PNEUMATIC HYBRID INTERNAL COMBUSTION ENGINE ON THE BASIS OF FIXED CAMSHAFTS

摘要

The invention is directed to an pneumatic hybrid internal combustion engine with at least one combustion chamber (3) composed of a cylinder in which a piston (2) is arranged mechanically interconnected to a crank shaft via a piston rod. An inlet valve (17) and an exhaust valve (19) are both mechanically interconnected via a valve gear to the crank shaft. The engine further comprises at least one charge valve (18) which is actuated by a charge valve actuator in a fully variable manner such that the engine can be operated in a four stroke hybrid mode.
