A control device (100) for an internal combustion engine (10) is provided that is configured to suppress a decrease in volumetric efficiency due to an influence of a pulsation of an intake air pressure that a turbo-supercharger (22) generates. In a case wh...

The process involves simultaneously opening inlet and exhaust valves of a cylinder in an inlet phase of a combustion cycle. Inlet and exhaust valves of another cylinder in compressed phase are closed. Exhaust valves of a third cylinder in exhaust phase is ...

A vacuum compensator for explosion engines which is used to be assembled in automobile engines and assembled in the suction opening for the intake of air from outside the air filter container, has a generally hollow cylindrical shape and has one of its bas...

An internal combustion engine (3) having a combustion heater (17) is constructed to prevent a thermal damage to the structure of an intake system (5) due to combustion heat emitted from the combustion heater (17). The engine includes the combustion heater ...
