Testing apparatus of engine valve mechanism rack

Abstract

The invention discloses a testing apparatus of an engine valve mechanism rack, and the testing apparatus comprises a rack, a water supply system, an oil supply system and a power mechanism, wherein the water supply system comprises a water supply plate and a water return plate respectively connected with the bottom of a cylinder cover and its side, a water supply cavity is formed inside the water supply plate which is provided with a plurality of water supply outlets connected with water inlets on the cylinder cover bottom, a water return cavity is formed inside the water return plate which is provided with water return outlets connected with the water return cavity, the water supply inlet is connected with the water return outlet through a pipe on which a circulating pump and a water tank are arranged, the oil supply system comprises an oil pipe connected with oil inlets and oil outlets on the cylinder cover, an oil pump and an oil tank. Through the testing apparatus of the engine valve mechanism rack, the water supply system and the oil supply system are simplified when multiple cylinders and valve mechanisms are realized in simulation, thus the testing apparatus is conveniently installed and disassembled, thereby effectively preventing water and oil from leakage.

Description

technical field [0001] The invention relates to the field of testing and testing of an engine valve mechanism, in particular to a bench test device for an engine valve mechanism. Background technique [0002] The engine is composed of engine casing, crankshaft mechanism, valve mechanism and intake and exhaust system. Among them, the function of the gas distribution mechanism is to open and close the intake valve and exhaust valve of each cylinder according to a certain rule according to the requirements of the working cycle or firing sequence in each cylinder of the engine, so as to promote the fresh combustible gas mixture gasoline engine or air diesel engine in time. Enter the cylinder and discharge the exhaust gas from the cylinder in time to obtain the best inflation and exhaust process, so as to ensure the best performance of the engine when working under different working conditions. The engine provides the power source for the operation of most mechanical equipment, ...

AI Technical Summary

Problems solved by technology

Conventional engine valve train bench test devices are mostly in the form of a single cylinder, and it is difficult to simulate a multi-cylinder, multi-valve valve train

Moreover, the pipelines of the oil supply and water supply systems in the conventional engine gas distribution mechanism bench test device are intricate, and it takes a long time for installation and disassembly and manpower. At the same time, there are also problems such as oil leakage and water leakage that are not easy to solve.
