Electromagnetic control valve actuation is a new kind of variable valve timing technology. It can offer more advantages than general camshaft valve actuation when used in the engine.

Valve timing is a major factor in achieving good volumetric efficiency.

Reasonable combination of exhaust valve timing and boost pressure can effectively control the combustion phase and minimize emissions.

Engine using variable valve timing technology can improve the intake charge, so that coefficient of charge increase, engine torque and power can be further improved.

Based on the previous study, the combustion stability of HCCI combustion under various loads and valve timing intervals was investigated and the reasons for combustion instability were analyzed.

Electromagnetic valve actuation (EVA) is a new kind of variable valve timing technology.

Large negative valve timing interval would be beneficial to the improvement of combustion stability under low load whereas and small valve interval was favorable to the stability under high load.

Two new engines are offered, each with fuel - saving direct injection and variable valve timing technology.

The utility model relates to a filtering apparatus, in particular to the filtering apparatus used for a variable air valve timing device.
