发动机润滑系统及发动机润滑方法
摘要：
一种发动机润滑系统及发动机润滑方法。该发动机润滑系统，包括：贮存机油的油底壳；机油泵，从油底壳泵送机油；主油道，接收机油泵所泵送的机油；与主油道并联设置的活塞冷却喷嘴油道，接收机油泵所泵送的机油，且设置有与活塞排气侧对准的活塞冷却喷嘴；在活塞冷却喷嘴油道中设置的机油电磁阀；以及电磁阀控制装置，根据机油温度和活塞温度控制机油电磁阀的开关，当机油温度低于所述机油温度预设值或者活塞温度高于所述活塞温度预设值时打开机油电磁阀，其中所述机油温度预设值小于所述活塞温度预设值。本发明既能够较好的冷却活塞，又能够在发动机冷启动时迅速提高机油温度，且可以更好地节约燃油消耗和保证发动机的可靠性。
摘要（英）：

The invention relates to an engine lubricating system and an engine lubricating method. The engine lubricating system includes an oil sump for storing engine oil, an engine oil pump pumping engine oil from the oil sump, a main oil gallery receiving the engine oil pumped by the engine oil pump, a piston cooling nozzle oil gallery connected with the main oil gallery in parallel, used for receiving the engine oil pumped by the engine oil pump, and provided with a piston cooling nozzle directed at the air exhaust side of a piston, an engine oil electromagnetic valve arranged in the piston cooling nozzle oil gallery, and an electromagnetic valve control device used for controlling the switch of the engine oil electromagnetic valve according to the temperature of the engine oil and the piston and starting the engine oil electromagnetic valve when the temperature of the engine oil is lower than the preset value of the engine oil temperature or the temperature of the piston is higher than the preset value of the piston temperature, wherein the preset value of the engine oil temperature is smaller than the preset value of the piston temperature. The engine lubricating system and the engine lubricating method not only can better cool the piston, but also can quickly increase the temperature of the engine oil when the engine is cold started, and better save the engine oil consumption and ensure the reliability of the engine.
