Valve Train System
Valve Train System
Valve train system is used to operate an intake valve of an internal combustion engine. In this, an operational amount of the intake valve is controlled. When there is a requirement of improving fuel efficiency then the compression ratio within the combustion chamber has been increased. This is done mainly on the basis of an engine operating state, which includes the opening and closing of intake stroke until the pressure within the exhaust chamber becomes equal to the pressure within the exhaust passage. It is provided only with the view to increase the compression ratio within the exhaust valve.
