ABSTRACT:
The clearance volume of a combustion chamber of an internal combustion engine at the same crankangle is varied by changing the location of a small piston reciprocally disposed in a small cylinder formed in a cylinder head, which small cylinder communicates with an engine cylinder. Changing the location of the small piston is controllable through a link mechanism in response to the movement of a throttle valve for controlling the amount of intake air supplied to the combustion chamber.
