一种减少热机时间的机油外循环装置及控制方法
摘要：
一种机油外循环装置，包括机油外循环装置输入管、机油冷却装置、机油外循环装置输出管，机油外循环装置输入管与油底壳连接以便将机油引入机油冷却装置以及机油冷却分配模块，机油冷却分配模块的输出端与机油输出管相连，机油冷却分配模块的一输入端与机油输入管连接，另一输入端又与机油冷却装置的出口相连，机油冷却模块中设有节温器。一种机油外循环控制方法，当发动机台架试验启动时，机油温度未达到第一温度，机油经由冷却分配模块后直接流向发动机本体；当机油温度处于第一温度和第二温度之间时，装配机油冷却模块中的节温器阀门部分打开，部分机油通过机油外循环装置进行冷却；当机油温度达到或超过第二温度时，节温器全开，全部机油通过机油外循环装置进行冷却。
摘要（英）：

An engine oil outside loop device comprises an inlet tube of the engine oil outside loop device, an engine oil cooling device and an outlet tube of the engine oil outside loop device. The inlet tube of the engine oil outside loop device is connected with an oil pan to introduce engine oil to the engine oil cooling device and an engine oil cooling distributing module, the outlet end of the engine oil cooling distributing module is connected with an engine oil outlet tube, one inlet end of the engine oil cooling distributing module is connected with the engine oil inlet tube, the other inlet end is connected with an outlet of the engine oil cooling device, and a thermostat is arranged in the engine oil cooling module. An engine oil outside loop control method includes steps that engine oil flows directly to the engine body through the cooling distributing module when an engine bed test starts and engine oil temperature does not reach a first temperature; when the engine oil temperature is between the first temperature and a second temperature, a valve portion of the thermostat of an assembly engine oil cooling module opens, part of engine oil cools through the engine oil outside loop device; when the engine oil temperature reaches or is beyond the second temperature, the thermostat opens completely, and all the engine oil cools through the engine oil outside loop device.
