Abstract

The invention discloses a device and a method for measuring an oil leakage amount of an engine. The device for measuring the oil leakage amount of the engine comprises a device main body and a pressure compensation device, a cavity is formed in the device main body, a feed opening and a gas outlet are formed in the cavity, a filtering device is arranged in the cavity to enable gas liquid to enterfrom the feed opening, so that the gas liquid is separated into a gas and oil after being filtered by the filtering device, and the gas is output from the gas outlet; the pressure compensation deviceis disposed on the device main body for adjusting the pressure value of the device main body, such that an output pressure value of the device main body is equivalent to an input pressure value. In the device disclosed by the invention, the filtering device can optimize the separation effect of the gas and liquid, and helps to completely separate the oil in the gas liquid; the pressure compensation device helps to eliminate the problem of increased internal resistance of the cavity caused by the arrangement of the filtering device, and table circulation of the gas liquid can be ensured by adjusting the pressure balance in the cavity, so that a more accurate measurement result is obtained.

Description

technical field [0001] The invention relates to the technical field of engine detection, in particular to the technical field of engine oil blow-by detection, and in particular to a device and method for measuring engine oil blow-by. Background technique [0002] Generally, the engine will generate blow-by gas mixed with combustible mixture and exhaust gas during the working process. The blow-by gas will escape into the crankcase from the gap between the piston ring and the cylinder liner. If it is not treated in time, it will cause engine damage. The pressure in the crankcase gradually increases, eventually leading to engine oil seal failure, oil leakage and other problems; moreover, if the blow-by gas is directly discharged into the atmosphere, it will also cause air pollution. Therefore, in order to ensure the normal operation of the engine, the crankcase is generally equipped with a forced ventilation system, which will guide the blow-by gas to the combustion chamber for...
