Abstract

The invention discloses a crankcase ventilation adjusting system and a control method. The crankcase ventilation adjusting system comprises a crankcase, a crankcase ventilation gas passage and an oil-gas separator; one end of the crankcase ventilation gas passage is connected with the crankcase, and the other end of the crankcase ventilation gas passage is connected with the oil-gas separator; thecrankcase ventilation adjusting system further comprises a sensor component, a controller and a crankcase ventilation adjuster. the crankcase ventilation adjuster communicates with the crankcase ventilation gas passage; the crankcase ventilation adjuster is provided with an oil passage, an engine oil pressure control valve, an oil pressure cavity, a pressure piece and an adjusting component; andthe oil pressure cavity communicates with the oil passage, the pressure piece is assembled in the oil pressure cavity and connected with the adjusting component, and the engine oil pressure control valve is installed in the oil passage. According to real-time signals measured by the sensor component, the controller controls opening and closing of the engine oil pressure control valve and adjusts the oil quantity of the oil pressure cavity, so that the pressure piece moves along the oil pressure cavity so as to rotate the adjusting component to a standard angle to adjust the speed of crankcaseventilation gas flowing to the oil-gas separator.

Description

technical field [0001] The invention relates to the field of engines, in particular to a crankcase ventilation regulating system and a control method for the crankcase ventilation regulating system. Background technique [0002] With the continuous development of engine technology, the power performance of the engine is continuously enhanced, but due to the enhancement of the power performance, the amount of bent gas leaked into the crankcase during the working process of the engine is also increasing. Among them, the curved gas includes the mixed gas of air, fuel oil and engine oil and the exhaust gas produced after combustion. If the bent gas stays in the crankcase, the water vapor contained in the exhaust gas will easily condense in the engine oil to form foam, which will damage the oil supply, dilute the engine oil in the crankcase, and change the physical parameters of the engine oil, causing serious damage to the engine operation. What is more serious is that the exha...
