Abstract
Description
本發明是有關於一種引擎進氣調節系統及裝置，且特別是有關於一種能夠在引擎加速時讓空氣經由輔助空氣濾清器進入引擎進氣岐管，令油/氣比因而可較接近理想值者。BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an engine intake air conditioning system and apparatus, and more particularly to an air intake manifold that allows air to enter an engine intake manifold via an auxiliary air filter, thereby making the oil/gas ratio relatively close to ideal. Value.
如第1圖所示，傳統的引擎進氣路徑包括從一空氣濾清器6引入空氣，經由風管7、引擎進氣岐管3，與燃油混合後被活塞吸入引擎燃燒室4。流量計(AFM)8用以偵測該風管裡的氣體流速產生信號，燃油控制系統9則可根據流量計8給予的信號控制噴油量，使至少在怠速時能維持最經濟的油/氣混合比，譬如使之維持於1；15的油/氣混合比。有些引擎燃燒室4下方的引擎曲軸箱5以一PCV閥51將廢氣引入進氣歧管3，以一呼吸軟管(breather hose)52通往風管7與大氣相通，藉此在運轉中維持箱內的壓力平衡。As shown in Fig. 1, the conventional engine intake path includes introducing air from an air cleaner 6, passing through the duct 7, the engine intake manifold 3, mixing with the fuel, and being sucked into the engine combustion chamber 4 by the piston. The flow meter (AFM) 8 is used to detect the gas flow rate in the air duct to generate a signal, and the fuel control system 9 can control the fuel injection amount according to the signal given by the flow meter 8, so that the most economical oil can be maintained at least at idle speed. The gas mixing ratio, for example, is maintained at an oil/gas mixture ratio of 1; The engine crankcase 5 below the engine combustion chamber 4 introduces exhaust gas into the intake manifold 3 by a PCV valve 51, and communicates with the atmosphere through a breath hose 52 to the air duct 7 to maintain the operation. The pressure inside the box is balanced.
由於引擎燃燒室4的廢氣難免有些通過活塞而洩漏到引擎曲軸箱5(此種氣體含有碳氫化合物(HC)及一氧化碳(CO)等有害的瓦斯)，為了不被直接排入大氣中，必須利用引擎進氣時的吸力將這些洩漏的廢氣引入引擎進氣歧管3，再度吸入引擎燃燒室4去燃燒。過去各國規定引擎必須裝設強制循環換氣的PCV(Positive Crankcase Ventilation Valve)閥51，使這些的有害健康的碳氫(CH)和氧化碳(CO)等化合物被再度燃燒，以避免直接排放後造成空氣的污染。Since the exhaust gas of the engine combustion chamber 4 is inevitably leaked to the engine crankcase 5 through the piston (the gas contains harmful gases such as hydrocarbons (HC) and carbon monoxide (CO)), in order not to be directly discharged into the atmosphere, it is necessary to These leaking exhaust gases are introduced into the engine intake manifold 3 by suction at the intake of the engine, and are again sucked into the engine combustion chamber 4 for combustion. In the past, countries have specified that the engine must be equipped with a PCV (Positive Crankcase Ventilation Valve) valve 51, so that these harmful health hydrocarbons (CH) and carbon oxide (CO) compounds are reburned to avoid direct discharge. Causes air pollution.
在實際的運作上，前揭傳統引擎尚存有下列缺點，亟待改善：1.由於呼吸軟管52與風管7相通，引擎活塞下行時會往下壓縮曲軸箱5內的空氣，使箱內的機油蒸汽被迫排入風管7，遇冷空氣時凝結在管壁上，對風管7造成無法清除的油漬污染。In actual operation, the conventional engine still has the following shortcomings, which need to be improved: 1. Since the breathing hose 52 communicates with the air duct 7, the engine piston will compress the air in the crankcase 5 downward when the engine piston descends, so that the air is inside the box. The oil vapor is forced into the air duct 7, and condenses on the pipe wall when it encounters cold air, causing oil pollution of the air duct 7 which cannot be removed.
2.引擎的進氣及噴油設計，頂多只能在怠速時達到1；15較經濟的油/氣混合比。而在突然加速、駕駛猛踩油門的瞬間，既有的進氣系統無法立刻補充足量的空氣，這時油/氣混合比將過濃而無法完全燃燒，產生耗油及空氣污染。2. The engine's intake and injection design can only reach 1; 15 at an idle speed than the economical oil/gas mixture ratio. At the moment of sudden acceleration and driving on the throttle, the existing air intake system cannot immediately replenish a sufficient amount of air. At this time, the oil/gas mixture ratio will be too rich to be completely burned, resulting in fuel consumption and air pollution.
為解決前述引擎加速時空氣無法立刻補足的問題，本發明提供一種引擎進氣調節系統，包括一調節裝置及一輔助空氣濾清器。其中調節裝置係連接於空氣濾清器與引擎進氣岐管之間，利用引擎加速時的吸力驟增，使外界空氣可以從輔助空氣濾清器進入引擎進氣岐管，藉此加速補足引擎加速時瞬間驟增的空氣需求。In order to solve the problem that the air cannot be immediately replenished when the engine is accelerated, the present invention provides an engine air intake adjusting system including an adjusting device and an auxiliary air filter. The adjusting device is connected between the air filter and the engine intake manifold, and the suction force when the engine is accelerated is suddenly increased, so that the outside air can enter the engine intake manifold from the auxiliary air filter, thereby accelerating the complementing engine. The sudden increase in air demand during acceleration.
調節裝置可為任何利用引擎進氣吸力變化而啟、閉的氣閥。本發明之調節裝置實施例，包括一殼體、一膜片、一閥門元件及一輔助空氣濾清器；其中膜片係將殼體分隔為一第一空間及一第二空間。在殼體內的第一空間設有一粗抽氣孔及一進氣口，第二空間設出一細抽氣孔。粗抽氣孔與細抽氣孔係分別通往引擎進氣岐管，當引擎加速時進氣的吸力驟增，可在膜片的上、下形成壓力差而驅動膜片所連接的閥門元件開啟粗抽氣孔與進氣口之間的通道，讓外界空氣得以從輔助空氣濾清器、調節裝置、進氣岐管被吸入引擎燃燒室幫助燃燒。The adjustment device can be any air valve that is opened and closed by utilizing changes in engine intake suction. The embodiment of the adjusting device of the present invention comprises a casing, a diaphragm, a valve component and an auxiliary air cleaner; wherein the diaphragm divides the casing into a first space and a second space. The first space in the casing is provided with a rough air vent and an air inlet, and the second space is provided with a fine air vent. The rough suction hole and the fine suction hole system respectively lead to the engine intake manifold. When the engine accelerates, the suction force of the intake air increases rapidly, and a pressure difference can be formed on the upper and lower sides of the diaphragm to drive the valve element connected to the diaphragm to open. The passage between the air vent and the air inlet allows outside air to be drawn into the engine combustion chamber from the auxiliary air filter, the regulating device, and the intake manifold to help burn.
為讓本發明之上述目的、特徵和優點能更明顯易懂，下文特舉較佳實施利，並配合所附圖式，作詳細說明如下：如第2圖所示，依據本發明的引擎進氣調節系統實施例，包括一調節裝置1及一輔助空氣濾清器2與一引擎的進氣路徑連接。其中調節裝置1係連接於輔助空氣濾清器2與引擎進氣岐管3之間。調節裝置1設有一氣體通路，不作動時關閉，作動時利用引擎加速時的吸力驟增打開，使外界空氣可以從輔助空氣濾清器2經過調節裝置1內的氣體通路進入引擎進氣岐管3，補充引擎加速瞬間驟增的空氣。The above described objects, features, and advantages of the present invention will become more apparent and appreciated from the following description. An embodiment of the air conditioning system includes an adjustment device 1 and an auxiliary air cleaner 2 coupled to an intake path of an engine. The adjusting device 1 is connected between the auxiliary air cleaner 2 and the engine intake manifold 3. The adjusting device 1 is provided with a gas passage, which is closed when not actuated, and is suddenly opened by the suction when the engine is accelerated during the operation, so that the outside air can enter the engine intake manifold from the auxiliary air cleaner 2 through the gas passage in the adjusting device 1. 3. The supplemental engine accelerates the sudden increase in air.
較佳者，可將引擎的呼吸軟管52改接至調節裝置1與輔助空氣濾清器2之間，在引擎活塞上行時，空氣可從輔助空氣濾清器2補入引擎曲軸箱5維持壓力平衡。在引擎加速時，引擎曲軸箱5內的廢氣和機油蒸氣將經由調節裝置1、引擎進氣岐管3被吸入引擎燃燒室4燃燒。如此不但可以解決機油蒸氣污染風管7的問題，同時又可藉由再度燃燒，避免廢氣直接排入大氣造成污染。Preferably, the breathing hose 52 of the engine can be connected between the adjusting device 1 and the auxiliary air cleaner 2, and when the engine piston is ascending, air can be replenished from the auxiliary air cleaner 2 to the engine crankcase 5 to maintain Pressure balance. When the engine is accelerating, the exhaust gas and the oil vapor in the engine crankcase 5 will be sucked into the engine combustion chamber 4 via the regulating device 1 and the engine intake manifold 3 to be combusted. This not only solves the problem of oil vapor pollution of the air duct 7, but also prevents the exhaust gas from being directly discharged into the atmosphere to cause pollution by re-combustion.
如第3圖所示，依據本發明之調節裝置實施例可包括一殼體10、一膜片11、一閥門元件12、一第一彈簧131及一輔助空氣濾清器2；其中膜片11係將殼體10分隔為一第一空間14及一第二空間15。在殼體10內的第一空間14設有一粗抽氣孔16及一進氣口17，而在第二空間設出一細抽氣孔18。As shown in FIG. 3, the embodiment of the adjusting device according to the present invention may include a housing 10, a diaphragm 11, a valve member 12, a first spring 131 and an auxiliary air cleaner 2; wherein the diaphragm 11 The housing 10 is partitioned into a first space 14 and a second space 15. The first space 14 in the casing 10 is provided with a rough air vent 16 and an air inlet 17, and a fine air vent 18 is provided in the second space.
粗抽氣孔16與細抽氣孔18係分別通往引擎進氣岐管3。此實施例係令細抽氣孔18所容許的單位空氣流量遠小於粗抽氣孔16，因此當引擎加速時，進氣量與吸力驟增，可造成第二空間15內的壓力相對地大於第一空間14，使在膜片11因此往第一空間14移動。The rough air vent 16 and the thin air vent 18 are respectively connected to the engine intake manifold 3. This embodiment is such that the unit air flow rate allowed by the thin air vent 18 is much smaller than that of the rough air vent 16, so that when the engine is accelerated, the intake air amount and the suction force are suddenly increased, so that the pressure in the second space 15 is relatively larger than the first. The space 14 is thus moved toward the first space 14 at the diaphragm 11.
殼體10於第一空間14設有一閘口140可開啟地與閥門元件12密接。第一彈簧131設於殼體10之內，用以保持閥門元件12與閘口140密接，用以在引擎不加速或怠速時截斷粗抽氣孔16與進氣口17之間的氣體通路。The housing 10 is provided with a gate 140 in the first space 14 to be in close contact with the valve member 12. The first spring 131 is disposed within the housing 10 for maintaining the valve member 12 in close contact with the gate 140 for intercepting the gas passage between the rough vent 16 and the intake port 17 when the engine is not accelerating or idling.
如第4圖所示意，閥門元件於第一空間14內與膜片11相連。當引擎加速，引擎進氣岐管3驟增的吸力使膜片11產生壓縮第一彈簧131力量而往第一空間14移動，藉此推動閥門元件12打開前述氣體通路，讓外界空氣得以從輔助空氣濾清器2、調節裝置內2的氣體通路和進氣岐管3，一路被吸入引擎燃燒室4幫助燃燒。As shown in Fig. 4, the valve member is connected to the diaphragm 11 in the first space 14. When the engine is accelerated, the sudden increase in suction of the engine intake manifold 3 causes the diaphragm 11 to compress the force of the first spring 131 to move toward the first space 14, thereby pushing the valve member 12 to open the aforementioned gas passage, allowing the outside air to be assisted. The air cleaner 2, the gas passage of the regulator 2, and the intake manifold 3 are all sucked into the engine combustion chamber 4 to assist combustion.
實施者可將第3圖所示之調節裝置1改成如第5圖所示的變化實施例。此實施例係在第二空間15裡面增加一第二彈簧132及一第二調整鈕180，並在第二調整鈕180形成一細抽氣孔181。第二調整鈕180可壓縮或放鬆第二彈簧132，以移動第一彈簧132第二彈簧132的平衡位置，調整閥門元件12與閘口140之間密接的緊度，以確保膜片11可在引擎加速時推動閥門元件12開啟閘口140。The implementer can change the adjustment device 1 shown in Fig. 3 to a modified embodiment as shown in Fig. 5. In this embodiment, a second spring 132 and a second adjustment button 180 are added to the second space 15, and a thin air vent 181 is formed in the second adjustment button 180. The second adjusting button 180 can compress or loosen the second spring 132 to move the balance position of the first spring 132 and the second spring 132 to adjust the tightness between the valve member 12 and the gate 140 to ensure that the diaphragm 11 can be in the engine. The valve member 12 is pushed to open the gate 140 during acceleration.
實施者亦可將第5圖所示之調節裝置1改成如第6圖所示的變化實施例。此實施例係在第一空間14裡面增加一第一調整鈕170，並在第一調整鈕170提供一進氣口170。此實施例可調整第一調整鈕170與第二調整鈕180的相對位置，改變其平衡位置及調整閥門元件12與閘口140之間密接的緊度，以確保膜片11可在引擎加速時推動閥門元件12開啟閘口140。The implementer can also change the adjusting device 1 shown in Fig. 5 to a modified embodiment as shown in Fig. 6. In this embodiment, a first adjustment button 170 is added to the first space 14, and an air inlet 170 is provided at the first adjustment button 170. This embodiment can adjust the relative position of the first adjusting button 170 and the second adjusting button 180, change its balance position and adjust the tightness between the valve member 12 and the gate 140 to ensure that the diaphragm 11 can be pushed when the engine accelerates. The valve member 12 opens the gate 140.
實施者又可將第3圖所示之調節裝置1改成如第7圖所示的變化實施例。此實施例係在第二空間15裡面增加一第三調整鈕190，包括一柄部1901以末端橫向地進入第二空間15的細抽氣孔191。藉由第三調整鈕190的柄部1901設有螺紋1902，利用螺紋1902調節細抽氣孔191的可通氣截面績，在引擎加速時可用以增大或減少膜片11朝第一空間14移動的力量，使開啟推動閥門元件12開啟閘口140的力量調至適當大小，以適應不同引擎的操作。The implementer can change the adjustment device 1 shown in Fig. 3 to a modified embodiment as shown in Fig. 7. In this embodiment, a third adjustment knob 190 is added to the second space 15, and a shank 1901 is formed to enter the fine air vent 191 of the second space 15 at the end. The shank 1901 of the third adjustment knob 190 is provided with a thread 1902, and the ventilating section of the fine vent 191 is adjusted by the thread 1902, and can be used to increase or decrease the movement of the diaphragm 11 toward the first space 14 when the engine is accelerated. The force is adjusted to increase the force that pushes the valve member 12 to open the gate 140 to an appropriate size to accommodate the operation of the different engines.
此外，熟習此項技藝者可依據第6圖所示之調節裝置1加以變化，譬如第8圖所示，在第二調整鈕180的一側設置一第三調整鈕190，藉由柄部1901的末端橫向地進入第二空間15的細抽氣孔181內改變其可通氣截面積，藉以調整細抽氣孔181的通氣速率。In addition, those skilled in the art can change according to the adjusting device 1 shown in FIG. 6. As shown in FIG. 8, a third adjusting button 190 is disposed on one side of the second adjusting button 180, and the handle 1901 is provided. The end of the end enters the fine air vent 181 of the second space 15 laterally to change its ventilating cross-sectional area, thereby adjusting the ventilation rate of the fine air vent 181.
本發明所提供之引擎進氣調節系統和裝置，與其他習用技術相比較時，至少具有下列優點：1.怠速時，調節裝置1的彈簧使閥門元件得以關閉氣體通路，因此不會影響引擎預設的最佳油/氣混合比；而當引擎在加速時，立刻在膜片11的上、下產生壓力差而自動打開氣體通路，空氣被從輔助空氣濾清器2吸入而加速補足，降低油/氣混合的濃度，使燃燒更加完全。The engine intake air conditioning system and apparatus provided by the present invention have at least the following advantages when compared with other conventional techniques: 1. When idling, the spring of the adjusting device 1 allows the valve element to close the gas passage, thus not affecting the engine pre- The optimal oil/gas mixture ratio is set; when the engine is accelerating, a pressure difference is generated immediately above and below the diaphragm 11, and the gas passage is automatically opened, and the air is sucked from the auxiliary air cleaner 2 to accelerate the filling and lowering. The concentration of oil/gas mixture makes the combustion more complete.
2.從輔助空氣濾清器2吸入的空氣溫度較低，可降低引擎溫度，減少有毒氣體NOx的排放量。2. The temperature of the air taken in from the auxiliary air cleaner 2 is low, which can reduce the engine temperature and reduce the NOx emissions of toxic gases.
3.將呼吸軟管52改接至調節裝置1與輔助空氣濾清器2之間，不但可避免引擎曲軸箱5裡的機油蒸氣在風管7裡積成油垢，在引擎加速時又可將廢氣與該機油蒸氣與從輔助空氣濾清器2吸入的空氣氣混合，一起被吸入引擎燃燒室5再度燃燒，減少有毒氣體的排放。3. Reconnecting the breathing hose 52 between the adjusting device 1 and the auxiliary air cleaner 2, not only can prevent the oil vapor in the crankcase 5 of the engine from accumulating grease in the air duct 7, and can be accelerated when the engine is accelerated. The exhaust gas and the oil vapor are mixed with the air gas sucked from the auxiliary air cleaner 2, and are sucked into the engine combustion chamber 5 to be combusted again to reduce the discharge of toxic gases.
以上所述之調節裝置，可為任何利用引擎進氣吸力變化而啟、閉的氣閥。以上詳細說明，僅係針對本發明之較佳實施例而言，惟該實施例並非用以限制本發明的專利範圍，凡未脫離本發明技藝精神所為之等效實施或更動，均應包含於本案的專利範圍中。The above-mentioned adjusting device can be any air valve that is opened and closed by the change of the intake air suction of the engine.
