Description
本發明係有關一種引擎的冷卻通道配置，尤指一種可避免水冷式引擎需另外接設一冷卻水供給管，該冷卻水供給管易受排氣管高溫之影響而產生裂化，使冷卻水供給管損壞而導致冷卻水外漏，進而影響到引擎的正常運作之缺失產生之引擎的冷卻通道配置。 The invention relates to a cooling channel arrangement of an engine, in particular to a water-cooled engine that needs to be additionally connected with a cooling water supply pipe, which is susceptible to cracking due to the high temperature of the exhaust pipe, so that the cooling water is supplied. The tube is damaged and the cooling water leaks, which affects the cooling channel configuration of the engine caused by the lack of normal operation of the engine.
按，引擎因散熱方式不同，可分為氣冷式引擎及水冷式引擎二種，其中，習知水冷式引擎1，如圖一、二所示，主要係於曲軸箱11上設置有汽缸本體12、汽缸頭13；該曲軸箱11之右側設水泵16，該水泵16罩設有水泵蓋161，該水泵蓋161上設有冷卻水輸入口1611，該冷卻水輸入口1611係與散熱器(圖中未示出)連接，該汽缸本體12上方設有汽缸頭13，而汽缸本體12內則設有一活塞14，該汽缸本體12設有冷卻水供給入口121及冷卻水通路122；該汽缸頭13設置有一進氣通道131及一排氣通道132，該排氣通道132上設有排氣管18，於汽缸頭13之下方處具有一燃燒室133；而汽缸頭13另設有一冷卻水出口134，藉此、藉由水泵16來輸送冷卻水於汽缸本體12及汽缸頭13中流動，最後冷卻水會通往散熱水箱(圖中未示出)進行散熱，以達到冷卻引擎1之目的。 According to the different heat dissipation modes, the engine can be divided into two types: an air-cooled engine and a water-cooled engine. Among them, the conventional water-cooled engine 1, as shown in Figs. 1 and 2, is mainly provided with a cylinder body on the crankcase 11. 12, the cylinder head 13; the right side of the crankcase 11 is provided with a water pump 16, the water pump 16 is covered with a water pump cover 161, the water pump cover 161 is provided with a cooling water input port 1611, the cooling water input port 1611 and the radiator ( A cylinder head 13 is disposed above the cylinder body 12, and a piston 14 is disposed in the cylinder body 12, and the cylinder body 12 is provided with a cooling water supply inlet 121 and a cooling water passage 122; the cylinder head 13 is provided with an intake passage 131 and an exhaust passage 132. The exhaust passage 132 is provided with an exhaust pipe 18 having a combustion chamber 133 below the cylinder head 13; and the cylinder head 13 is further provided with a cooling water outlet. 134. Thereby, the cooling water is sent by the water pump 16 to flow in the cylinder body 12 and the cylinder head 13. Finally, the cooling water is sent to a heat dissipation tank (not shown) for heat dissipation to cool the engine 1.
再如圖一、二、三所示，由於輸送冷卻水之主要動力源水泵16係設置於曲軸箱11之右側，當水泵16由散熱器(圖中未示出)抽出輸送到該汽缸本體12之冷卻水供給入口121及冷卻水通路122時，該汽缸本體12及汽缸頭13與水泵16同側設置有迴油室15，因此必須由水泵16之冷卻水輸出口162外接軟性材質的冷卻水供給管17，該冷卻水供給管17繞過汽缸本體12下方至汽缸本體12的另一 側，來接設於汽缸本體12之冷卻水供給入口121，藉此來令冷卻水得以於汽缸本體12及汽缸頭13中流動。習用上述冷卻水通路的構造，藉由一外接的冷卻水供給管17才能令冷卻水得於汽缸本體12及汽缸頭13中流動，因該冷卻水供給管17係為外接的橡膠軟管並繞設汽缸本體12下方，且係位於排氣管18的上方，因此易造成該冷卻水供給管17因排氣管18高溫之影響而產生裂化，使冷卻水供給管17損壞而導致冷卻水外漏，進而影響到引擎的正常運作。因此如何能改善習用上述冷卻水通路之缺失，實為機車業者亟待解決之重要課題。 As shown in FIG. 1 , FIG. 2 and FIG. 3 , since the main power source water pump 16 for conveying cooling water is disposed on the right side of the crankcase 11 , the water pump 16 is pumped out to the cylinder body 12 by a radiator (not shown). When the cooling water supply inlet 121 and the cooling water passage 122 are provided, the cylinder main body 12 and the cylinder head 13 are provided with the oil return chamber 15 on the same side as the water pump 16. Therefore, the cooling water outlet 162 of the water pump 16 must be connected to the soft cooling water. Supply pipe 17, the cooling water supply pipe 17 bypasses the lower side of the cylinder body 12 to the other of the cylinder body 12 The side is connected to the cooling water supply inlet 121 of the cylinder body 12, whereby the cooling water is allowed to flow in the cylinder body 12 and the cylinder head 13. With the above-described structure of the cooling water passage, the cooling water can be supplied to the cylinder body 12 and the cylinder head 13 by an external cooling water supply pipe 17, because the cooling water supply pipe 17 is an external rubber hose and wound. The cylinder body 12 is disposed below the exhaust pipe 18, so that the cooling water supply pipe 17 is likely to be cracked due to the high temperature of the exhaust pipe 18, and the cooling water supply pipe 17 is damaged to cause leakage of the cooling water. , which in turn affects the normal operation of the engine. Therefore, how to improve the lack of the above-mentioned cooling water passage is an important issue that the locomotive industry needs to solve urgently.
