MECHANISM FOR DEACTIVATION OF CYLINDERS IN INTERNAL COMBUSTION ENGINES

摘要

The inventionis a Mechanism for deactivation of cylinders in internal combustion engines summarized as the cancellation of the functioning of one or more cylinders in an internal combustion engine, by means of the release and locking of the springs which close the inlet and exhaust valves in order to keep them closed and open respectively and simultaneously. The closed inlet valve prevents the intake of gases or fuels from the inlet manifold and the open exhaust valve prevents compression of the gas contained in the combustion chamber of the deactivated cylinder, so that the latter avoids fuel consumption and compression efforts during periods of low demand on engine power.
