to more closely control the system compared to the previous pressure type, to
increase reaction speed of cam, to improve startability, and to reduce the emission
of exhaust gas. Also, operation range of intake valve (valve opening angle)
is expanded. So, the output and fuel efficiency are improved.
Components
