Abstract
Description
本案涉及內燃機領域，特別是一種可以提升輸出扭力與功率的噴射注油引擎。 This case relates to the field of internal combustion engines, especially a jet fueling engine that can increase the output torque and power.
一般的四行程引擎包括有進氣、壓縮、***、排氣四個作動行程，該四個行程連續地循環作動以驅動曲軸連續旋轉，從而達到動力輸出之目的。 The general four-stroke engine includes four actuation strokes of intake, compression, explosion, and exhaust, and the four strokes continuously circulate to drive the crankshaft to continuously rotate, thereby achieving the purpose of power output.
上述四行程引擎已經很普遍與成熟地使用於交通工具，尤其是汽車與機車，當四行程引擎的汽車或機車要求提升速度與加速度時，多採用提升工作轉速、增大汽缸容積以及多汽缸並聯等方式來工作。 The above four-stroke engine has been widely and maturely used in vehicles, especially in automobiles and locomotives. When a four-stroke engine car or locomotive requires speed and acceleration, it is often used to increase the working speed, increase the cylinder volume, and connect multiple cylinders in parallel. Waiting for the way to work.
提升工作轉速可增加輸出功率，但是轉速增加也會使得進氣行程時間縮短，致使在自然進氣中明顯會有進氣不足的問題。增大汽缸容積，尤其是加大活塞行程，也使得進氣不足，在自然進氣中更明顯是功率輸出的瓶頸，造成工作轉速難以提升，也難以提升扭力與工作功率輸出。 Increasing the working speed increases the output power, but the increase in the speed also causes the intake stroke time to be shortened, resulting in a significant shortage of intake air in the natural intake. Increasing the cylinder volume, especially increasing the piston stroke, also makes the intake air insufficient. In the natural intake air, the bottleneck of the power output is more obvious, which makes it difficult to increase the working speed, and it is difficult to increase the torque and the working power output.
為了解決上述進氣不足的問題，坊間提供了多種改良進氣方式的引擎；其中之一的方式為增大進氣閥門口徑；其二的方式為增加進氣閥門數量；其三的方式為增大進氣閥門間隙；其四的方式為增大進氣閥門開啟時間；其五的方式為預先將空氣壓縮再注入汽缸；如此可以在相同運作條件下獲得更大量的進氣量，能夠有效提升引擎工作轉速、輸出更大扭力與功率。 In order to solve the above problem of insufficient intake air, a variety of engines for improving the intake mode are provided. One of them is to increase the diameter of the intake valve; the other is to increase the number of intake valves; the third way is to increase Large intake valve clearance; the fourth way is to increase the intake valve opening time; the fifth way is to compress the air into the cylinder beforehand; so that a larger amount of intake air can be obtained under the same operating conditions, which can effectively improve The engine works at a higher speed and outputs more torque and power.
坊間所提供的預先將空氣壓縮以改良進氣的方式又有兩種：其一為利用引擎排出的廢氣驅動渦輪增壓器而預先將空氣壓縮後再進氣；其二為利 用引擎輸出的動力驅動渦輪增壓器或驅動螺旋空壓機，預先將空氣壓縮再進氣；這兩種方式均有良好結果與商品推出。 There are two ways to compress the air in advance to improve the intake air. One is to use the exhaust gas from the engine to drive the turbocharger and compress the air before re-injecting the air; The engine output power drives the turbocharger or drives the screw air compressor to compress and re-intake the air in advance; both methods have good results and products are introduced.
利用引擎排出的廢氣驅動渦輪增壓器以預先將空氣壓縮再進氣的缺點是必須額外增加高轉速渦輪增壓器，且需要與排放廢氣及進氣的管路連接，在空間上的安排不易，又需要在高、低溫與高、低轉速的環境下工作，其維修與使用壽命短是主要考量的問題；另一個次要問題是在低轉速工作時的效果並不明顯，尤其在短距離加速競賽中急劇加速時會感覺動力輸出有延遲現象。而利用引擎驅動渦輪增壓器或螺旋空壓機以預先將空氣壓縮再進氣來改善上述問題的效果較明顯，但是仍然需要額外增加渦輪增壓器或螺旋空壓機，而且要與引擎輸出軸及進氣管配合連接，在空間的安排上不易仍是問題。 The disadvantage of using the exhaust gas from the engine to drive the turbocharger to compress and re-intake the air in advance is that an extra-high speed turbocharger must be added, and the pipeline connecting the exhaust gas and the intake air is required, and the space arrangement is not easy. It also needs to work in high, low temperature and high and low speed environment. Its maintenance and short service life are the main considerations; another minor problem is that the effect is not obvious when working at low speed, especially in short distance. When the acceleration is accelerated in the accelerated race, the power output is delayed. The use of an engine-driven turbocharger or a screw air compressor to compress air and re-intake the air to improve the above problems is more obvious, but an additional turbocharger or screw compressor is required, and the engine output is required. The shaft and the intake pipe are connected and connected, and it is not easy to solve the problem in space arrangement.
本案的目的在於改善將空氣預先壓縮再進氣的習知引擎在空間的安排不易以及維修與使用壽命短的問題，同時可以進一步降低引擎製造成本。 The purpose of this case is to improve the problem that the conventional engine that pre-compresses and re-intakes air is difficult in space and the maintenance and service life are short, and the engine manufacturing cost can be further reduced.
本案的特徵是以習知的多缸式引擎為基礎，將其中部分汽缸改為進氣預先壓縮空氣的汽缸，空氣被壓縮後再經由引擎工作汽缸的進氣閥門於進氣行程時注入該工作汽缸中，以獲得額外空氣進氣量，再執行一般引擎的壓縮、***、排氣行程，完成引擎四行程的工作，達成增加扭力輸出及提升引擎功率的目的。 The feature of the present invention is based on a conventional multi-cylinder engine, in which some of the cylinders are changed to cylinders that are pre-compressed air, and the air is compressed and then injected into the intake stroke through the intake valves of the engine working cylinders. In the cylinder, to obtain the additional air intake amount, and then perform the compression, explosion, and exhaust stroke of the general engine, complete the four strokes of the engine, and achieve the purpose of increasing the torque output and increasing the engine power.
藉由本案所改良後的增壓進氣引擎，其在執行進氣、壓縮、***、排氣的四行程過程中曲軸需要旋轉兩圈，而曲軸旋轉兩圈則使得空壓汽缸完成預先進氣壓縮兩次，以四汽缸引擎來計算：曲軸每旋轉兩圈，原來的進氣量為四單位，每單位不考慮進氣效率為該氣缸的排氣量，如果將其中兩汽缸改變為空壓汽缸，改變後的空壓汽缸採用進氣-壓縮二行程工作，使得二個空壓汽缸的進氣量也是四單位，再加上原來未改變的二個工作汽缸原有的二單位進氣 量，總計可以獲得六單位的進氣量；如前面所述，因為進氣量是引擎扭力及功率輸出瓶頸所在，故藉由此方式可以在相同條件下得到1.5倍的空氣輸入量，因而可提高引擎扭力輸出及功率的目的；並且，此引擎的法定排氣量只有原來的一半，更可大幅節省車輛的相關稅金。 With the boosted intake engine improved in this case, the crankshaft needs to rotate two times during the four strokes of performing intake, compression, explosion, and exhaust, and the two rotations of the crankshaft enable the air compressor to complete the pre-intake. Compressed twice, calculated by four-cylinder engine: every two revolutions of the crankshaft, the original intake air amount is four units, and the unit does not consider the intake efficiency as the displacement of the cylinder. If two cylinders are changed to air pressure Cylinder, the changed air compressor cylinder adopts the intake-compression two-stroke operation, so that the intake air volume of the two air compressor cylinders is also four units, plus the original two-unit air intake of the two working cylinders that have not been changed. A total of six units of intake air can be obtained; as mentioned above, since the intake air amount is the engine torque and the power output bottleneck, by this way, 1.5 times the air input can be obtained under the same conditions, thus The purpose of increasing the torque output and power of the engine; and the legal exhaust capacity of this engine is only half of the original, and can significantly save the relevant taxes of the vehicle.

本案之增壓進氣引擎的運作方式如下：引擎先藉由電力啟動使曲軸3旋轉，曲軸3則分別帶動第一工作活塞11A、第二工作活塞11B、第一空壓活塞21A及第二空壓活塞21B往復移動，且曲軸3同時經由時規皮帶輪G1和G2配合時規皮帶L帶動凸輪軸4以半速旋轉以控制該等第一壓縮空氣進氣閥門13A、第一自然進氣閥門13A1、第一廢氣排氣閥門14A、第二壓縮空氣進氣閥門13B、第二自然進氣閥門13B1、第二廢氣排氣閥門14B、第 一空氣進氣閥門23A、第一空氣排氣閥門24A、第二空氣進氣閥門23B及第二空氣排氣閥門24B的開啟與關閉時序。當第一工作活塞11A與第二工作活塞11B分別在第一工作汽缸1A與第二工作汽缸1B內往下方移動時進行進氣行程，此時適量的外部空氣輪流從第一自然進氣閥門13A1與第二自然進氣閥門13B1進入第一工作汽缸1A與第二工作汽缸1B，以及經由第一空氣進氣閥門23A與第二空氣進氣閥門23B進入第一空壓汽缸2A與第二空壓汽缸2B，再經由噴射注油管7將適量燃油適時地注入第一工作汽缸1A與第二工作汽缸1B內，然後在第一壓縮空氣進氣閥門13A與第二壓縮空氣進氣閥門13B輪流關閉後，第一工作活塞11A與第二工作活塞11B分別輪流往第一工作汽缸1A與第二工作汽缸1B的上方移動以進行壓縮行程，在第一工作活塞13A與第二工作活塞13B分別接近上死點時藉由電路控制火星塞點火，使注入的燃油燃燒產生動力以推動第一工作活塞11A與第二工作活塞11B往下方移動(即***行程)；第一工作活塞11A與第二工作活塞11B越過下死點後則再往上方移動以進行排氣行程，使第一工作汽缸1A與第二工作汽缸1B內的廢氣分別經由第一廢氣排氣閥門14A與第二廢氣排氣閥門14B排出(即排氣行程)；前述的進氣、壓縮、***、排氣行程連續地進行並且循環，從而驅動曲軸3持續地運轉。 The supercharged intake engine of the present invention operates as follows: the engine first rotates the crankshaft 3 by electric power, and the crankshaft 3 drives the first working piston 11A, the second working piston 11B, the first air compressor piston 21A and the second air respectively. The pressure piston 21B reciprocates, and the crankshaft 3 simultaneously rotates the camshaft 4 at half speed through the timing pulleys G1 and G2 to control the first compressed air intake valve 13A and the first natural intake valve 13A1. a first exhaust gas exhaust valve 14A, a second compressed air intake valve 13B, a second natural intake valve 13B1, a second exhaust gas exhaust valve 14B, The opening and closing timings of an air intake valve 23A, a first air exhaust valve 24A, a second air intake valve 23B, and a second air exhaust valve 24B. When the first working piston 11A and the second working piston 11B move downward in the first working cylinder 1A and the second working cylinder 1B, respectively, an intake stroke is performed, and an appropriate amount of external air is alternately flowed from the first natural intake valve 13A1. And the second natural intake valve 13B1 enters the first working cylinder 1A and the second working cylinder 1B, and enters the first air cylinder 2A and the second air pressure via the first air intake valve 23A and the second air intake valve 23B. The cylinder 2B, in turn, injects an appropriate amount of fuel into the first working cylinder 1A and the second working cylinder 1B via the injection oil filling pipe 7, and then turns off after the first compressed air intake valve 13A and the second compressed air intake valve 13B are turned off. The first working piston 11A and the second working piston 11B are respectively rotated to move above the first working cylinder 1A and the second working cylinder 1B to perform a compression stroke, and the first working piston 13A and the second working piston 13B are respectively close to each other. When the point is controlled by the circuit to control the ignition of the spark plug, the injected fuel is combusted to generate power to push the first working piston 11A and the second working piston 11B downward (ie, the explosion stroke); After the plug 11A and the second working piston 11B pass the bottom dead center, they move upward again to perform the exhaust stroke, and the exhaust gases in the first working cylinder 1A and the second working cylinder 1B are respectively passed through the first exhaust gas exhaust valve 14A and the first The exhaust gas exhaust valve 14B is exhausted (i.e., the exhaust stroke); the aforementioned intake, compression, explosion, and exhaust strokes are continuously performed and circulated, thereby driving the crankshaft 3 to continuously operate.
曲軸3連續運轉時則分別經由第一空壓連桿22A與第二空壓連桿22B驅動第一空壓活塞21A與第二空壓活塞21B分別在第一空壓汽缸2A及第二空壓汽缸2B內往復移動；第一空壓汽缸2A及第二空壓汽缸2B並沒有設置火星塞，因此第一空壓活塞21A與第二空壓活塞21B分別在第一空壓汽缸2A及第二空壓汽缸2B內僅進行進氣與壓縮二個行程。請配合第3圖所示，其中，當第一工作汽缸1A在進氣行程時，第一空壓汽缸2A亦進行進氣行程，此時，引擎外部的空氣經由空氣輸送管5及第一自然進氣閥門13A1被吸入第一工作汽缸1A中，以及經由空氣輸送管5及第一空氣進氣閥門23A被吸入第一空壓汽缸2A中；稍後，在第一工 作汽缸1A進行壓縮行程之中，第一空壓汽缸2A已進行壓縮行程，將第一空壓汽缸2A內的空氣壓縮後通過第一壓縮空氣排氣閥門24A經第一輸氣管6A及第一壓縮空氣進氣閥門13A注入第一工作汽缸1A中，藉此增加第一工作汽缸1A內的額外空氣量，從而提升其在***行程中的輸出功率，以及提升輸出扭力。同樣的，當第二工作汽缸1B在進氣行程時，第二空壓汽缸2B亦進行進氣行程，此時，引擎外部的空氣經由空氣輸送管5及第二自然進氣閥門13B1被吸入第二工作汽缸1B中，以及經由空氣輸送管5及第二空氣進氣閥門23B被吸入第二空壓汽缸2B中；稍後，在第二工作汽缸1B進行壓縮行程之中，第二空壓汽缸2B已進行壓縮行程，將第二空壓汽缸2B內的空氣壓縮後通過第二壓縮空氣排氣閥門24B經第二輸氣管6B及第二壓縮空氣進氣閥門13B注入第二工作汽缸1B中，藉此增加第二工作汽缸1B內的額外空氣量，從而提升其在***行程中的輸出功率，以及提升輸出扭力。 When the crankshaft 3 is continuously operated, the first air pressure piston 21A and the second air pressure piston 21B are respectively driven by the first air pressure connecting rod 22A and the second air pressure connecting rod 22B at the first air pressure cylinder 2A and the second air pressure, respectively. The cylinder 2B reciprocates; the first air cylinder 2A and the second air cylinder 2B are not provided with a spark plug, so the first air compressor piston 21A and the second air compressor piston 21B are respectively in the first air cylinder 2A and the second In the air compressor cylinder 2B, only two strokes of intake and compression are performed. Please cooperate with FIG. 3 , wherein when the first working cylinder 1A is in the intake stroke, the first air cylinder 2A also performs an intake stroke. At this time, the air outside the engine passes through the air delivery pipe 5 and the first natural The intake valve 13A1 is sucked into the first working cylinder 1A, and is sucked into the first pneumatic cylinder 2A via the air delivery pipe 5 and the first air intake valve 23A; later, at the first work During the compression stroke of the cylinder 1A, the first air compressor cylinder 2A has undergone a compression stroke, compresses the air in the first air compressor cylinder 2A, passes through the first compressed air exhaust valve 24A through the first air delivery pipe 6A, and the first The compressed air intake valve 13A is injected into the first working cylinder 1A, thereby increasing the amount of additional air in the first working cylinder 1A, thereby increasing its output power during the explosion stroke and increasing the output torque. Similarly, when the second working cylinder 1B is in the intake stroke, the second pneumatic cylinder 2B also performs an intake stroke. At this time, the air outside the engine is sucked through the air delivery pipe 5 and the second natural intake valve 13B1. The second working cylinder 1B is sucked into the second pneumatic cylinder 2B via the air delivery pipe 5 and the second air intake valve 23B; later, during the compression stroke of the second working cylinder 1B, the second pneumatic cylinder 2B has performed a compression stroke, compresses the air in the second air compressor cylinder 2B, and then injects it into the second working cylinder 1B through the second compressed air exhaust valve 24B through the second air supply duct 6B and the second compressed air intake valve 13B through the second compressed air exhaust valve 24B. This increases the amount of additional air in the second working cylinder 1B, thereby increasing its output power during the explosion stroke and increasing the output torque.
前述第一空氣進氣閥門23A、第一壓縮空氣排氣閥門24A、第二空氣進氣閥門23B及第二壓縮空氣排氣閥門24B的開啟與關閉時序除了可以藉由凸輪軸4來控制之外，本案也可以將該第一空氣進氣閥門23A、第一壓縮空氣排氣閥門24A、第二空氣進氣閥門23B及第二壓縮空氣排氣閥門24B分別設為單向閥門，因而可以藉由該第一空氣進氣閥門23A以及第二空氣進氣閥門23B前後的壓力差使其自動開啟或關閉，以及藉由第一壓縮空氣排氣閥門24A及第二壓縮空氣排氣閥門24B前後的壓力差使該壓縮空氣排氣閥門自動開啟或關閉；此種結構構無需時規皮帶、凸輪軸、汽門頂桿等複雜零件，可以進一步降低製造成本與維修成本。 The opening and closing timings of the first air intake valve 23A, the first compressed air exhaust valve 24A, the second air intake valve 23B, and the second compressed air exhaust valve 24B may be controlled by the camshaft 4 In this case, the first air intake valve 23A, the first compressed air exhaust valve 24A, the second air intake valve 23B, and the second compressed air exhaust valve 24B may be respectively configured as one-way valves, thereby The pressure difference between the first air intake valve 23A and the second air intake valve 23B is automatically opened or closed, and the pressure difference between the first compressed air exhaust valve 24A and the second compressed air exhaust valve 24B is The compressed air exhaust valve is automatically opened or closed; such a structure does not require complex parts such as a timing belt, a camshaft, a valve stem, etc., which can further reduce manufacturing costs and maintenance costs.
再者，第一圖所示之引擎所包含的四個汽缸係以並列方式排列，然而在其他實施例中，可以將複數汽缸對臥排列(如第4圖所示)，也可以採用V形排列(如第5圖所示)，或是星形排列(如第6圖所示)。此外，考量輸氣管長度的 配置，前述各種排列的複數汽缸最好使工作汽缸與空壓汽缸相互交錯地並列排列、相互交錯地對臥排列、相互交錯地V形排列或相互交錯地星形排列。 Furthermore, the four cylinders included in the engine shown in the first figure are arranged in a side by side manner. However, in other embodiments, the plurality of cylinders may be arranged side by side (as shown in FIG. 4) or may be V-shaped. Arrange (as shown in Figure 5) or star-shaped (as shown in Figure 6). In addition, consider the length of the gas pipe Preferably, the plurality of cylinders of the various arrangements described above preferably have the working cylinders and the air compressor cylinders alternately arranged side by side, alternately arranged in a staggered manner, and alternately arranged in a V-shape or alternately arranged in a star shape.
由於不同的引擎採用不同的燃料，致使對於引擎汽缸的壓縮比有特別的要求，因此，本發明之被第一工作連桿12A與第二工作連桿12B連接的曲軸3部位，以及被第一空壓連桿22A與第二空壓連桿22B連接的曲軸3部位分別具有不同的偏心量或者有不同的上死點容積，使得該等第一、二工作汽缸與該該第一、二空壓汽缸具有不同的壓縮比。 Since different engines use different fuels, there is a special requirement for the compression ratio of the engine cylinders. Therefore, the crankshaft 3 portion of the present invention connected by the first working link 12A and the second working link 12B is first The portions of the crankshaft 3 connected to the air pressure connecting rod 22A and the second air pressure connecting rod 22B respectively have different eccentricities or different top dead center volumes, so that the first and second working cylinders and the first and second air cylinders The pressure cylinders have different compression ratios.
前述的各個第一空壓汽缸2A與第二空壓汽缸2B係具有相同的汽缸容積與壓縮比，然而在另外的實施例中，該第一空壓汽缸2A與第二空壓汽缸2B可以分別具有不同的汽缸容積及壓縮比，且該等空壓汽缸內的空壓活塞的作動時序各不相同，使該空氣壓縮機藉由各自不相同之汽缸容積與壓縮比而達到分段壓縮空氣之功能。 Each of the foregoing first air compressor cylinders 2A and second air compressor cylinders 2B has the same cylinder volume and compression ratio. However, in other embodiments, the first air compressor cylinder 2A and the second air compressor cylinder 2B may respectively Having different cylinder volumes and compression ratios, and the operation timings of the air pressure pistons in the air compressor cylinders are different, so that the air compressor achieves segmented compressed air by different cylinder volumes and compression ratios. Features.
前述的實施例係包含有二個空壓汽缸，然而在另一實施例中，也可以僅提供一個較大的空壓汽缸，該較大的空壓汽缸可以具有雙倍以上於工作缸的容積，且該空壓汽缸的壓縮空氣排氣閥門同時連接至二個工作汽缸的壓縮空氣進氣閥門，使單一較大的空壓汽缸所預先壓縮的空氣被輪流同時輸送至不同的工作汽缸以提升進氣與增加功率輸出，並降低製造成本與使用時間。 The foregoing embodiment includes two air compressor cylinders. However, in another embodiment, only one larger air compressor cylinder may be provided, and the larger air compressor cylinder may have a volume more than double the working cylinder. And the compressed air exhaust valve of the air compressor cylinder is simultaneously connected to the compressed air intake valves of the two working cylinders, so that the pre-compressed air of the single large air compressor cylinder is simultaneously sent to different working cylinders in turn to promote Intake and increased power output, and reduce manufacturing costs and usage time.
習知的二行程引擎也包含有前述四行程引擎的曲軸、連桿、汽缸與活塞等結構，但汽缸內活塞係進行壓縮與***二個行程，使活塞經連桿帶動曲軸持續旋轉而得以輸出更大動力，並且不需設置四行程引擎的進排氣閥門、凸輪等結構，其輕巧且製造成本較低，但因為排放的廢氣中含有未能完全燃燒之機油而產生了環保問題，亟待改善。 The conventional two-stroke engine also includes the crankshaft, the connecting rod, the cylinder and the piston of the aforementioned four-stroke engine, but the piston in the cylinder performs two strokes of compression and explosion, so that the piston is continuously rotated by the connecting rod to output the crankshaft. More power, and no need to set up the four-stroke engine intake and exhaust valves, cams and other structures, which are light and low in manufacturing cost, but because the exhaust gas contains oil that is not completely combusted, it creates environmental problems and needs to be improved. .
基於本發明將空氣壓縮機整合於引擎免除了曲軸所需潤滑油隨進氣進入汽缸的問題，也一併改善了前述機油未能完全燃燒的環保問題；且前 述本發明實施例之四行程引擎中的空氣壓縮機也沒有四行程引擎所需要的時規皮帶、凸輪軸、彈簧、進氣閥門、排氣閥門、汽門頂桿、…等零件，因此，本發明的增壓進氣引擎構造也可以適用於二行程引擎提升功率輸出，使得在相同法定排氣量的條件下，二行程引擎還有較四行程引擎雙倍的***行程，還具有較四行程引擎的結構簡單輕巧且製造維修成本更低的優點。 The invention integrates the air compressor into the engine to eliminate the problem that the lubricating oil required for the crankshaft enters the cylinder with the intake air, and also improves the environmental protection problem that the foregoing oil is not completely burned; The air compressor in the four-stroke engine of the embodiment of the present invention also does not have the timing belt, the camshaft, the spring, the intake valve, the exhaust valve, the valve ejector, etc. required by the four-stroke engine, therefore, The supercharged intake engine structure of the present invention can also be applied to the two-stroke engine to increase the power output, so that under the condition of the same legal exhaust volume, the two-stroke engine has twice the explosion stroke of the four-stroke engine, and has four more. The structure of the stroke engine is simple and light, and the manufacturing cost is lower.
如第7圖係顯示本發明之增壓進氣引擎應用於二行程引擎的實施例前視平面示意圖。第7圖顯示了該高功率二行程引擎包括有一工作汽缸1C與一空壓汽缸2C，其中，工作汽缸1C的缸體上端設置點火裝置與燃油噴嘴，燃油噴嘴則連接噴射注油管7以供應注入燃油；工作汽缸1C的缸體側壁不同位置分別設置一壓縮空氣進氣閥門13C與一廢氣排氣閥門14C，壓縮空氣進氣閥門13C與廢氣排氣閥門14C的各自閥門的開啟與關閉是由工作汽缸1C內的工作活塞11C經由一工作連桿12C活動連接至曲軸3，藉此，曲軸旋轉時得以經由機構的設計而控制工作活塞11C在工作汽缸1C內往復運動，並且在工作活塞11C往復運動的過程中，依預定的時序使廢氣排氣閥門14C及壓縮空氣進氣閥門13C開啟或關閉，以達成上述優點。但是仍有習知二行程引擎在廢氣未完全排出時空氣進氣閥門即已開啟進氣，致使部分進氣從廢氣排氣閥門排出之浪費，雖然採用缸內噴入燃料無燃料浪費，但採下述方式改善進氣免於浪費。 Figure 7 is a front plan view showing an embodiment of the turbocharged engine of the present invention applied to a two-stroke engine. Figure 7 shows that the high-power two-stroke engine includes a working cylinder 1C and an air-pressure cylinder 2C, wherein the upper end of the cylinder of the working cylinder 1C is provided with an ignition device and a fuel nozzle, and the fuel nozzle is connected to the injection fuel injection pipe 7 for supplying fuel injection. A compressed air intake valve 13C and an exhaust gas exhaust valve 14C are respectively disposed at different positions of the cylinder side wall of the working cylinder 1C, and the respective valves of the compressed air intake valve 13C and the exhaust gas exhaust valve 14C are opened and closed by the working cylinder. The working piston 11C in 1C is movably connected to the crankshaft 3 via a working link 12C, whereby the working piston 11C is controlled to reciprocate in the working cylinder 1C via the mechanism design, and reciprocates in the working piston 11C. In the process, the exhaust gas exhaust valve 14C and the compressed air intake valve 13C are opened or closed according to a predetermined timing to achieve the above advantages. However, there is still a known two-stroke engine that the air intake valve has opened the intake air when the exhaust gas is not completely exhausted, so that some of the intake air is discharged from the exhaust gas exhaust valve, although the fuel injected into the cylinder is fuel-free, but The intake is improved from waste in the following manner.
第8圖顯示另一種更佳的二行程引擎實施例，係在第7圖所示的二行程引擎基礎上，將第7圖所示之工作汽缸1C之壓縮空氣進氣閥門13C與廢氣排氣閥門14C由第一連桿13C1及第二連桿14C1與曲軸3活動連接增設在工作汽缸1C外之滑套閘門8而可上下作動；其作動時序為在曲軸的旋轉角度中，工作汽缸活塞11C落後滑套閘門8九十度，並使得滑套閘門8的行程約為工作汽缸11C的一半或更小；在滑套閘門8適當位置分別開出進氣孔隙81及排氣孔隙82，達成工作活塞11C在***行程接近下死點前先開啟廢氣排氣閥門14C再開啟壓縮空氣進氣 閥門13C，而在進氣時關閉廢氣排氣閥門14C，除滿足前述防止進氣從廢氣排氣閥門排出之浪費。 Figure 8 shows another preferred two-stroke engine embodiment. Based on the two-stroke engine shown in Figure 7, the compressed air intake valve 13C of the working cylinder 1C shown in Figure 7 is exhausted. The valve 14C is movably connected to the crankcase 3 by the first link 13C1 and the second link 14C1 and the crankshaft 3 to be actuated up and down by the sliding sleeve gate 8 outside the working cylinder 1C; the actuation timing is the working cylinder piston 11C in the rotation angle of the crankshaft. The sliding sleeve gate is 8 ninety degrees, and the stroke of the sliding sleeve gate 8 is about half or less of the working cylinder 11C; the intake aperture 81 and the exhaust aperture 82 are respectively opened at the appropriate position of the sliding sleeve gate 8 to achieve work. The piston 11C opens the exhaust gas exhaust valve 14C and then opens the compressed air intake before the explosion stroke approaches the bottom dead center. The valve 13C closes the exhaust gas exhaust valve 14C at the time of intake, in addition to satisfying the aforementioned waste of preventing intake of the exhaust gas from the exhaust gas exhaust valve.
以上所述者僅為用以解釋本案之較佳實施例，並非企圖據以對本案做任何形式上之限制，是以，凡有在相同之發明精神下所作有關本案之任何修飾或變更，皆仍應包括在本發明意圖保護之範疇。 The above description is only for the purpose of explaining the preferred embodiment of the present invention, and is not intended to impose any form of limitation on the case, so that any modifications or changes to the case made in the same spirit of the invention are It should still be included in the scope of the claimed invention.
