Description
本發明係有關於一種引擎的吹漏氣機構，尤指一種可確保該吹漏氣機構可以發揮油氣分離之效果，俾使引擎可有效的減少潤滑油油氣之排出量，而可減少潤滑油之損耗量，並可有降低引擎排放廢氣之污染之引擎的吹漏氣機構。 The invention relates to a blow-by-gas mechanism of an engine, in particular to ensuring that the blow-by-gas mechanism can exert the effect of oil and gas separation, so that the engine can effectively reduce the discharge of lubricating oil and gas, and can reduce the lubricating oil. The amount of loss, and the blow-by-gas mechanism of the engine that reduces the pollution of the engine exhaust.
按，引擎1係為高速的運轉之機械，為避免引擎1之各構件(包括活塞、曲軸、凸輪軸等)，因接觸摩擦的增加，而造成損壞，因此引擎1均有設置油潤滑系統，該油潤滑系統提供了潤滑油來潤滑引擎1各構件之目的。 According to the engine 1, the engine 1 is a high-speed running machine. In order to prevent the components of the engine 1 (including the piston, the crankshaft, the camshaft, etc.) from being damaged due to the increase of the contact friction, the engine 1 is provided with an oil lubrication system. The oil lubrication system provides lubricating oil for the purpose of lubricating the components of the engine 1.
惟，引擎1在運轉中會不斷的產生高熱，而潤滑油會因蒸發而產生油蒸氣，該油蒸氣稱為吹漏氣，為避免該吹漏氣直接被排放至大氣中而產生空氣污染，引擎1的曲軸箱11上會設置一吹漏氣機構2，藉由該吹漏氣機構2來達到潤滑油油氣分離的目的。 However, the engine 1 will continuously generate high heat during operation, and the lubricating oil will generate oil vapor due to evaporation. The oil vapor is called blow-by gas, and air pollution is generated to prevent the blow-by gas from being directly discharged into the atmosphere. A blow-by gas mechanism 2 is disposed on the crankcase 11 of the engine 1, and the blow-by gas mechanism 2 achieves the purpose of lubricating oil and gas separation.
如圖一、二所示，該吹漏氣機構2係設於汽缸本體13的後側方，該吹漏氣機構2上端設有油氣排出口21，該油氣排出口21係連結至空氣濾清器(圖式中未匯出)，該吹漏氣機構2內設置迷宮構造22，藉由該迷宮構造22之阻繞及導引，來令進入吹漏氣機構2的部份潤滑油之油氣會凝結而恢復成油體狀，經由該吹漏氣機構2的潤滑油回流口23來回流至曲軸箱11內而能 再使用，另一部份的潤滑油之油氣則由油氣排出口21排出至空氣濾清器，藉此可避免潤滑油之油氣於曲軸箱11內形成龐大的油氣壓力，而影響引擎1正常之運作。 As shown in FIG. 1 and FIG. 2, the blow-by gas mechanism 2 is disposed on the rear side of the cylinder body 13. The upper end of the blow-off gas mechanism 2 is provided with an oil and gas discharge port 21, and the oil and gas discharge port 21 is connected to the air filter. The labyrinth structure 22 is disposed in the blow-off mechanism 2, and the oil and gas entering the lubricating oil of the blow-by gas mechanism 2 is blocked by the labyrinth structure 22 It will be condensed and returned to the oil body shape, and can be returned to the crankcase 11 through the lubricating oil return port 23 of the blow-by gas mechanism 2, and can be When used again, the oil and gas of another part of the lubricating oil is discharged from the oil and gas discharge port 21 to the air filter, thereby preventing the oil and gas of the lubricating oil from forming a huge oil and gas pressure in the crankcase 11, and affecting the normal operation of the engine 1 Operation.
再請參閱如圖二所示，該吹漏氣機構2的潤滑油回收口23，一般係設於曲軸箱11的右曲軸箱體111上，且該吹漏氣機構2的潤滑油回流口23的出口係朝向曲軸箱11的下側方向開設；然而，引擎1於右曲軸箱體111設置有離合器12，該離合器12的運轉方向係為逆時鐘方向運轉(如圖二中的箭頭方向)，該離合器12運轉時會將右曲軸箱體111處的潤滑油飛甩，因此被離合器12飛甩的潤滑油，除可使離合器12獲得潤滑油之油潤外，同時可將該潤滑油飛散到右曲軸箱體111內部各處，藉此來潤滑右曲軸箱體111內的其他構件。惟，該潤滑油被離合器12的運轉而飛散時，該飛散的潤滑油會對該吹漏氣機構2的潤滑油回收口23形成一壓力，進而會使原欲從吹漏氣機構2的潤滑油回收口23回流的潤滑油，無法順利的回流到右曲軸箱體111內再使用；另，被離合器12飛甩而飛散的潤滑油一部份，更會被飛甩由吹漏氣機構2的潤滑油回收口23進入吹漏氣機構2，進而造成吹漏氣機構2無法有效的發揮油氣分離之效果。 Referring to FIG. 2 again, the lubricating oil recovery port 23 of the blow-by gas mechanism 2 is generally disposed on the right crankcase body 111 of the crankcase 11, and the lubricating oil return port 23 of the blow-by gas mechanism 2 The outlet is opened toward the lower side of the crankcase 11; however, the engine 1 is provided with a clutch 12 in the right crankcase 111, and the running direction of the clutch 12 is reversed (as indicated by the arrow in FIG. 2). When the clutch 12 is in operation, the lubricating oil at the right crankcase body 111 will fly, so that the lubricating oil that is caught by the clutch 12 can be dissipated by the lubricating oil of the clutch 12, and the lubricating oil can be scattered to the lubricating oil. The entire crankcase 111 is located inside, thereby lubricating other components in the right crankcase 111. However, when the lubricating oil is scattered by the operation of the clutch 12, the scattered lubricating oil forms a pressure on the lubricating oil recovery port 23 of the blow-by gas mechanism 2, thereby causing lubrication of the original blow-by gas leakage mechanism 2. The lubricating oil returned from the oil recovery port 23 cannot be smoothly returned to the right crankcase 111 for use; and a part of the lubricating oil that is scattered by the clutch 12 is more likely to be blown by the blow-by gas mechanism 2 The lubricating oil recovery port 23 enters the blow-by gas mechanism 2, thereby causing the blow-by gas mechanism 2 to effectively perform the effect of oil and gas separation.
因此習用之引擎的吹漏氣機構，實有改善之必要，是以如何能提供一種確保能達成油氣分離的引擎的吹漏氣機構，實為車輛業者亟待解決之一大課題。 Therefore, the blow-by-gas mechanism of the conventional engine is necessary for improvement, and it is a major problem for the vehicle industry to solve the problem of how to provide a blow-by-gas mechanism for ensuring an engine that can achieve oil and gas separation.

Since the opening direction of the lubricating oil return port 54 of the blow-by gas mechanism 5 is opened in the direction of rotation of the clutch 7, when the labyrinth structure 51 of the blow-by gas mechanism 5 has condensed into lubricating oil, it is intended to be blown therefrom. When the lubricating oil return port 54 of the air leakage mechanism 5 flows back into the crankcase 3, the lubricating oil that has condensed in the labyrinth structure 51 can be smoothly returned to the crankcase 3 by the right crankcase 31 without any hindrance. Further, since the lubricating oil return port 54 of the blow-by gas mechanism 5 is disposed in the recessed portion 311, it is possible to prevent the lubricating oil scattered by the clutch 7 from being rushed into the lubricating oil return port of the blow-by gas leakage mechanism 5 54 flows into the labyrinth structure 51, thereby ensuring that the blow-by gas mechanism 5 can An effect the separation of oil and gas.
本發明功效在於，藉由該右曲軸箱體31於與右曲軸箱蓋33結合側設有一凹部311，該吹漏氣機構5的迷宮結構51的潤滑油回流口54係設於該凹部311內，且該吹漏氣機構5的潤滑油回流口54的開口方向於右曲軸箱體31的凹部311係成斜向設置，亦即該吹漏氣機構5的潤滑油回流口54的開口方向，於右曲軸箱體31的凹部311係朝曲軸箱3的後方設置，且該吹漏氣機構5的潤滑油回流口54開口方向，係朝安裝於右曲軸箱體31凹部311外側的離合器7轉動的方向順向開設； 藉此，該吹漏氣機構5的迷宮結構51內已凝結成的潤滑油即可在無任何阻礙下順暢的由該右曲軸箱體31回流至曲軸箱3內；同時藉由該吹漏氣機構5的潤滑油回流口54係設於該凹部311內，而能避免被離合器7因運作而飛散的潤滑油飛入吹漏氣機構5的潤滑油回流口54，而流入迷宮結構51內，進而能確保該吹漏氣機構5可以發揮油氣分離之效果，俾使引擎A可有效的減少潤滑油油氣之排出量，而可減少潤滑油之損耗量，並可有降低引擎A排放廢氣之污染。 The effect of the present invention is that a recess 311 is formed on the side of the right crankcase 31 coupled to the right crankcase cover 33, and the lubricating oil return port 54 of the labyrinth structure 51 of the blow-by gas mechanism 5 is disposed in the recess 311. The opening direction of the lubricating oil return port 54 of the blow-storch mechanism 5 is obliquely disposed in the recessed portion 311 of the right crankcase 31, that is, the opening direction of the lubricating oil return port 54 of the blow-by gas mechanism 5, The concave portion 311 of the right crankcase 31 is disposed toward the rear of the crankcase 3, and the lubricating oil return opening 54 of the blow-by gas mechanism 5 is rotated toward the clutch 7 attached to the outside of the concave portion 311 of the right crankcase 31. Directions are opened in the direction; Thereby, the lubricating oil that has condensed in the labyrinth structure 51 of the blow-by gas mechanism 5 can be smoothly returned from the right crankcase 31 to the crankcase 3 without any hindrance; The lubricating oil return port 54 of the mechanism 5 is disposed in the recessed portion 311, and the lubricating oil scattered by the clutch 7 due to the operation can be prevented from flying into the lubricating oil return port 54 of the blow-by gas mechanism 5, and flows into the labyrinth structure 51. Furthermore, it can be ensured that the blow-by-gas mechanism 5 can exert the effect of oil and gas separation, so that the engine A can effectively reduce the discharge amount of the lubricating oil and gas, and can reduce the loss of the lubricating oil, and can reduce the pollution of the exhaust gas of the engine A. .
