Internal combustion engine for car, has valve head allowing sealing between additional chamber and combustion chamber by valve body that seals opening of additional chamber for allowing fluid connection with combustion chamber

摘要

The engine has a conduit (3') opening into an additional chamber (14) of a cylinder head that is in fluid connection with a combustion chamber (1'). A valve head (5'b) slides in the additional chamber for sealing between the conduit and the additional chamber associated with a valve on a suitable seat located in a connection region between the conduit and the additional chamber, and for sealing between the additional chamber and the combustion chamber by a valve body (5') that seals the opening of the additional chamber for allowing a fluid connection (15) with the combustion chamber.
