Description

引擎節流閥體結構 Engine throttle body structure

本發明係有關一種引擎節流閥體結構，尤指一種可避免節流閥體的感知器盒體受到引擎回火衝擊而損害之缺失產生，進而來提升節流閥體使用功效之引擎節流閥體結構。 The invention relates to an engine throttle body structure, in particular to an engine throttle which can avoid the loss of damage caused by the engine tempering impact of the throttle body of the throttle body, thereby improving the efficiency of the throttle body. Valve body structure.

按，用於噴射引擎的節流閥體1，如圖一所示，至少包括有一閥本體11、一設於閥本體11內的節流閥12，以及一插設於閥本體11上的溫度壓力感知器13。 The throttle body 1 for the injection engine, as shown in FIG. 1, includes at least a valve body 11, a throttle valve 12 disposed in the valve body 11, and a temperature inserted into the valve body 11. Pressure sensor 13.

該閥本體11具有一可供空氣流通的空氣通道111，該節流閥12係設於該空氣通道111內，該節流閥12具有一閥桿121，該閥桿121穿設出該閥本體11外；該閥本體11於該空氣通道111的出氣端側壁設有一插設孔112，該插設孔112連通著該空氣通道111，該溫度壓力感知器13係插設於該插設孔112上，藉此該溫度壓力感知器13可以感測該空氣通道111的出氣端的大氣壓力與溫度，並將所測得的大氣壓力與溫度訊息傳遞給引擎控制中心(ECU)(圖式中未繪出)，來作為行車控制重要參考訊息。 The valve body 11 has an air passage 111 through which the air is circulated. The throttle valve 12 is disposed in the air passage 111. The throttle valve 12 has a valve stem 121. The valve stem 121 passes through the valve body. The valve body 11 is provided with an insertion hole 112 at the air outlet end side of the air passage 111. The insertion hole 112 communicates with the air passage 111. The temperature pressure sensor 13 is inserted into the insertion hole 112. Thereby, the temperature pressure sensor 13 can sense the atmospheric pressure and temperature of the air outlet end of the air passage 111, and transmit the measured atmospheric pressure and temperature information to the engine control center (ECU) (not drawn in the drawing) Out), as an important reference message for driving control.

如圖一所示，該溫度壓力感知器13係插設於該閥本體11的插設孔112上，該插設孔112直接連通著該空氣通道111；然而， 如眾所周知，引擎運作時當活塞由下死點向上推移時，提供進氣與排氣的進、排氣閥有一小段時間係成同時開啟狀，因此有一部份的燃爆後之廢氣會混合部份的油氣，由進氣閥被推進該節流閥體1內，此種現象一般稱為回火，該回火所推進該節流閥體1內的廢氣與部份的油氣會經由該插設孔112而接觸到該溫度壓力感知器13；更明確的說，由於該插設孔112直接連通著該空氣通道111，因此該溫度壓力感知器13會被該回火推進該節流閥體1內的廢氣與部份的油氣所汙染，從而失去感測功能，更嚴重者，該廢氣通常含有燃燒不完全的碳粒，該碳粒更易堆積而使該溫度壓力感知器13失去感測能力，另外該回火現象發生時，該溫度壓力感知器13會偵測瞬間的高壓力，此一高壓力訊息傳遞到引擎控制中心(ECU)後，會造成引擎控制中心(ECU)誤判，嚴重時會造成行車的安全受到威脅；是以，上述供該溫度壓力感知器13安裝用的該插設孔112直接連通著該空氣通道111，造成該溫度壓力感知器13因引擎之回火而容易損害失效，亦即該溫度壓力感知器13設於出氣端，因此溫度的感測後受到回火影響致使測得溫度不正確，而實有加以改善之必要。 As shown in FIG. 1, the temperature and pressure sensor 13 is inserted into the insertion hole 112 of the valve body 11, and the insertion hole 112 directly communicates with the air passage 111; however, As is well known, when the engine is running up when the piston is pushed up from the bottom dead center, the intake and exhaust valves for the intake and exhaust are provided for a short period of time to open simultaneously, so that some of the exhaust gas after the explosion will be mixed. The oil and gas is propelled into the throttle body 1 by an intake valve. This phenomenon is generally referred to as tempering. The tempering promotes the exhaust gas and part of the oil and gas in the throttle body 1 through the plug. The hole 112 is provided to contact the temperature pressure sensor 13; more specifically, since the insertion hole 112 directly communicates with the air passage 111, the temperature pressure sensor 13 is urged to the throttle body by the tempering The exhaust gas in 1 is contaminated with part of the oil and gas, thereby losing the sensing function. More seriously, the exhaust gas usually contains incompletely burnt carbon particles, which are more likely to accumulate and cause the temperature and pressure sensor 13 to lose the sensing capability. In addition, when the tempering phenomenon occurs, the temperature pressure sensor 13 detects an instantaneous high pressure, and after the high pressure message is transmitted to the engine control center (ECU), the engine control center (ECU) may be misjudged. Will cause the safety of driving The above-mentioned insertion hole 112 for the temperature and pressure sensor 13 is directly connected to the air passage 111, so that the temperature and pressure sensor 13 is easily damaged by the tempering of the engine, that is, the temperature. The pressure sensor 13 is disposed at the air outlet end, so that the temperature is sensed and the tempering effect causes the measured temperature to be incorrect, which is necessary for improvement.

如圖二所示，乃有業者開發出一引擎控制中心(ECU)2，該引擎控制中心(ECU)2內容包含有溫度壓力感知器(圖式中未繪出)，該引擎控制中心(ECU)2凸設出一感測孔柱21，該感測孔柱21來插設於該閥本體11的插設孔112上；然而，當引擎有回火現象時，該回火所推進該節流閥體1內的廢氣與部份的油氣，依然會經由該插設孔112再由該感測孔柱21進入引擎控制中心(ECU)2內，同樣的會使設於該引擎控制中心(ECU)2內的溫度壓力感知器損害；因此，該引 擎控制中心(ECU)2內容包含有溫度壓力感知器之方式，仍然無法解決引擎回火所造成溫度壓力感知器損害之缺失。 As shown in Fig. 2, a manufacturer has developed an engine control center (ECU) 2, which contains a temperature and pressure sensor (not shown in the drawing), and the engine control center (ECU) 2, a sensing hole column 21 is protruded, and the sensing hole column 21 is inserted into the insertion hole 112 of the valve body 11; however, when the engine has a tempering phenomenon, the tempering advances the section The exhaust gas and part of the oil and gas in the flow valve body 1 will still enter the engine control center (ECU) 2 through the insertion hole 112 through the insertion hole 112, and the same will be provided in the engine control center ( Temperature and pressure sensor damage in ECU) 2; therefore, the reference The engine control center (ECU) 2 contains the temperature and pressure sensor, and still can not solve the lack of temperature and pressure sensor damage caused by engine tempering.

如圖三所示，為解決引擎回火所造成溫度壓力感知器13損害之缺失，乃有業者於該節流閥體1的閥本體11上，以加工的方式鑽設一連通空氣通道111的溫度壓力引入部14，該溫度壓力引入部14係由第一通道141、一第二通道142所構成，該第一通道141連通該閥本體11的空氣通道111，該第二通道142一端連通第一通道141，另一端連通著該溫度壓力感知器13，其中該第二通道142連通第一通道141的端頭填塞著一阻塞珠143，該第一通道141連通該第二通道142的端頭亦填塞一阻塞珠144；藉由該第一通道141、第二通道142形成一轉折狀之感測通道，藉此祈能避免該引擎回火直接衝擊該溫度壓力感知器13；然而，藉由該第一通道141、第二通道142形成一轉折狀之感測通道的加工費用，會造成該節流閥體1的使用成本過高，況且該第一通道141、第二通道142形成一轉折狀之感測通道，其對於避免引擎回火直接衝擊該溫度壓力感知器13效果仍然不佳，同時亦無法解決該溫度壓力感知器13會偵測瞬間的高壓力，並將此一高壓力訊息傳遞到引擎控制中心(ECU)造成引擎控制中心(ECU)誤判之缺失；另且，該第二通道142的端頭所填塞的阻塞珠143，以及該第一通道141的端頭所填塞的阻塞珠144，會產生加工精度與洩漏之問題。 As shown in FIG. 3, in order to solve the problem of the damage of the temperature and pressure sensor 13 caused by the tempering of the engine, a manufacturer drills a communication air passage 111 on the valve body 11 of the throttle body 1 in a processing manner. The temperature and pressure introduction portion 14 is composed of a first passage 141 and a second passage 142. The first passage 141 communicates with the air passage 111 of the valve body 11, and the second passage 142 is connected at one end. a channel 141, the other end of which is connected to the temperature and pressure sensor 13, wherein the end of the second channel 142 communicating with the first channel 141 is filled with a blocking bead 143, and the first channel 141 is connected to the end of the second channel 142. A blocking bead 144 is also filled; the first channel 141 and the second channel 142 form a turning-shaped sensing channel, thereby avoiding the engine tempering directly impacting the temperature pressure sensor 13; however, by The processing cost of the first channel 141 and the second channel 142 forming a turn-shaped sensing channel may cause the use cost of the throttle body 1 to be too high, and the first channel 141 and the second channel 142 form a turning point. Sensing channel Avoiding the tempering of the engine directly impacts the temperature. The pressure sensor 13 is still not effective, and at the same time, the temperature pressure sensor 13 is not able to detect the high pressure of the moment, and the high pressure message is transmitted to the engine control center (ECU). Causing the engine control center (ECU) to misjudge the fault; in addition, the blocking bead 143 stuffed at the end of the second passage 142, and the blocking bead 144 filled in the end of the first passage 141, will produce machining precision and The problem of leakage.

緣是，如何能提供一種可避免引擎回火直接衝擊該溫度壓力感知器之節流閥體結構，已為車輛業者亟待解決之課題。 The reason is that how to provide a throttle body structure that can avoid the engine tempering directly impacting the temperature pressure sensor has been an urgent problem for the vehicle industry.
