Description
本發明係關於一種引擎機油冷卻器油路控制裝置，尤指一種適用於機車引擎之機油冷卻器油路控制裝置。The invention relates to an engine oil cooler oil circuit control device, in particular to an oil cooler oil circuit control device suitable for a locomotive engine.
傳統跨坐式機車氣冷引擎大多採用自然空冷之冷確方式，為提高機油的耐久性與穩定性常，一般會加裝機油冷卻器，用以控制機油油溫於一合適值。為了確保引擎基本潤滑油量不被減少，此一冷卻器需串聯於原本潤滑系統油路，避免引擎損壞。Most of the conventional straddle-type locomotive air-cooled engines adopt the natural air-cooling method. In order to improve the durability and stability of the oil, an oil cooler is generally installed to control the oil temperature at a suitable value. In order to ensure that the engine's basic lubricant quantity is not reduced, this cooler must be connected in series with the original lubrication system oil circuit to avoid engine damage.
請參閱圖1係習知引擎機油冷卻器油路控制裝置之示意圖，其潤滑油路包括有一油底殼90、一機油泵92、一潤滑機件94、一機油冷卻器96及複數連通管91,93,95,97。其中，機油泵入口921藉由連通管91與油底殼出口902相互連通，潤滑機件入口941藉由連通管93與機油泵出口922相互連通，機油冷卻器入口961藉由連通管95與潤滑機件出口942相互連通，而機油冷卻器出口962則藉由連通管97與油底殼入口901相互連通。亦即，機油冷卻器96係串聯於原本潤滑系統油路中，不論引擎是在熱車或冷車之狀況，機油冷卻器96皆會對潤滑油產生冷卻之效果。Please refer to FIG. 1 for a schematic diagram of a conventional engine oil cooler oil circuit control device. The lubricating oil circuit includes an oil pan 90, an oil pump 92, a lubricating machine 94, an oil cooler 96 and a plurality of communicating tubes 91. , 93, 95, 97.

That is, the oil cooler 96 is connected in series with the original lubricating system oil circuit, and the oil cooler 96 cools the lubricating oil regardless of whether the engine is in a hot or cold state.
隨著環保意識抬頭與有限資源影響下，引擎的排污與油耗表現已被嚴格的汙染法規所限制，上述習知加裝機油冷卻器96的引擎會使得熱車時間拉長，並使冷車的油耗變差，並非十分理想。此外，若於原本潤滑系統油路串聯節溫器，因其係利用節溫器來控制機油潤滑油量之大小，潤滑油量並不固定，有時又將使得潤滑油量不足，亦非十分理想，尚有改善之空間。With the rise of environmental awareness and limited resources, the engine's sewage and fuel consumption performance has been limited by strict pollution regulations. The above-mentioned engine with the oil cooler 96 will make the hot car time longer and make the cold car The fuel consumption is getting worse and it is not very ideal. In addition, if the original lubrication system oil circuit series thermostat, because it uses the thermostat to control the amount of oil, the amount of lubricant is not fixed, and sometimes the amount of lubricant is insufficient, not very Ideal, there is still room for improvement.
發明人原因於此，本於積極發明創作之精神，亟思一種可以解決上述問題之「引擎機油冷卻器油路控制裝置」，幾經研究實驗終至完成本發明。The inventor's reason is that, in the spirit of active invention and creation, he thought of an "engine oil cooler oil circuit control device" that can solve the above problems, and finally completed the present invention after several research experiments.
