GENERAL

Variable valve lift system of SOHC engine is the system that aims at the improvement of fuel efficiency, the improvement of engine output, and the decrease of toxic substances in exhaust gas, etc.

It changes the lift amount of intake valve to low-lift or high-lift according to the engine driving status. Then, the combustion status of air-fuel mixture has been improved in the medium-low speed area.In the high-speed area, the intake air efficiency has been improved. As a result, the engine output improves, and at the same time the fuel efficiency improves.
