Abstract

The invention discloses an electromagnetic control valve for an engine VVA system, and relates to the field of electromagnetic control valves, the electromagnetic control valve comprises a valve sleeve and a valve element, the electromagnetic control valve is additionally arranged at an engine cam shaft, and the operation of the electromagnetic control valve is adaptively adjusted according to the working condition of an engine; by controlling the on-off of the two oil ways in the electromagnetic valve and the oil quantity in the oil ways, the effect of adjusting a cam adjuster is achieved, so that the air inflow of the cam of the engine is controlled, fuel oil can be fully combusted no matter the engine is in a high-rotating-speed area or a low-rotating-speed area, emission is further reduced, and the purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the field of electromagnetic control valves, in particular to an electromagnetic control valve used in a VVA system of an engine. Background technique [0002] With the development of society, energy saving and emission reduction is an inevitable trend. As a driving system, the energy saving and emission reduction of the engine is becoming more and more serious. It is the key to development to reduce engine emissions while increasing engine power. [0003] When the engine is under high load, the camshaft adjuster is used to optimize the valve lift according to the engine speed, so as to supply as much fresh air to the combustion chamber as possible, so as to achieve high power and torque. However, in the actual running process of the engine, if the adjustment of the camshaft adjuster is not timely, the fuel combustion of the engine will not be sufficient, resulting in waste of resources. [0004] The invention adjusts the cam...
