Abstract

The invention provides an engine detection device, an engine and a vehicle. The detection device of the engine includes: an intake module, which is connected to the intake port of the crankcase, and the intake module is used to deliver air to the crankcase; a first flow control module is arranged on the connecting pipeline between the intake module and the crankcase , the first flow control module is used to control the amount of intake air entering the crankcase; the second flow control module is arranged on the connecting pipeline between the crankcase and the oil-gas separator, and the second flow control module is used to control the intake of the oil-gas separator The first detection module is connected with the oil and gas separator, and the detection module is used to detect the separation efficiency information of the oil and gas separator. The detection device provided in this embodiment can realize the adjustable air leakage of the test engine. In this way, the separation efficiency information of the oil-gas separator under different air leakage of the engine can be dynamically measured, and the obtained data is the same as the actual state, which can more accurately test the performance of the designed oil-gas separator.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to an engine detection device, an engine and a vehicle. Background technique [0002] When the internal combustion engine is working, the gas flow from the combustion chamber into the crankcase through the cylinder liner and the piston assembly is called the crankcase leakage. The size of the crankcase leakage reflects the cooperation between the piston ring and the cylinder and the piston ring and the piston ring. and wear condition. [0003] In fact, during the use of the engine, with the continuous extension of the engine use time, the engine piston rings and cylinder liners will continue to wear, and the leakage of the engine will increase. In order to ensure that the oil and gas separator can still perform effectively within a certain range of air leakage, a certain safety margin will be considered in the design. [0004] The oil and gas separator is used as the...
