Abstract

The invention discloses an electro-hydraulic valve for an engine and a working system thereof. The electro-hydraulic valve for the engine comprises an oil cylinder, a plunger and a valve body. An oil cylinder cover is arranged on the top of the oil cylinder, and a first oil cavity and a second oil cavity which are communicated with each other are formed in the oil cylinder. The plunger comprises a piston and a piston rod, wherein one end of the piston rod is perpendicularly arranged in the middle of the lower surface of the piston, the piston is arranged in the first oil cavity, and the other end of the piston rod penetrates through the second oil cavity, stretches out of the oil cylinder and can push the valve body to move vertically. According to the working system of the electro-hydraulic valve for the engine, an automobile computer controls opening or closing of an intake valve oil pressure control valve or an exhaust valve oil pressure control valve according to signals acquired by a crankshaft rotation speed signal sensor and a crankshaft angle and position signal sensor, and therefore the valve body in the electro-hydraulic valve for the engine can move to achieve intake or exhaust of the engine. By means of the electro-hydraulic valve for the engine and the working system thereof, the optimal intake or exhaust effect of the engine can be achieved.

Description

technical field [0001] The invention relates to an improvement of an engine valve, in particular to an engine electric hydraulic valve and its working system which can improve the best intake and exhaust effects of the engine. Background technique [0002] In the current mechanical manufacturing field, there are some reciprocating motions that need to be realized by camshafts, balance wheels or worms. For example, in the automotive engine manufacturing industry, the reciprocating motion of the valve has always been realized by the rotational motion of the camshaft. The valve train parts that drive the valve movement include camshaft, tappet, push rod, rocker arm, rocker shaft, rocker shaft seat and valve clearance adjustment screw, camshaft driven gear, transmission chain or toothed belt, transmission Chain guides, tensioners, half-moon keys, camshaft thrust plates, cam bearing caps and other components have complex structures, large layout space, high manufacturing costs, a...
