Because the use environment of the diesel engine is relatively bad, in the working process of the engine, the engine oil with proper quantity, pressure and temperature is always required to be continuously conveyed to the transmission part of the engine through the lubricating system, so that the friction force is reduced, the power consumption is reduced and the abrasion is lightened, and therefore, in the use process of the engine, the temperature and pressure sensors are always required to be arranged for detecting the pressure and the temperature of the oil.
