A control device for an engine comprises an intake control valve disposed in an intake passage at an upstream side of an intake valve in each cylinder for individually opening/closing the intake passage, an actuator for opening/closing the intake control v...

A system for controlling exhaust gas temperature of an internal combustion engine having a combustion cycle frequency and being provided with an exhaust gas after-treatment device. The system includes a combustion airflow control valve adapted for position...

The internal-combustion engine system has an exhaust reconduction plant (6) having a fresh air valve unit (27), with which a introduction stream entering from a return line (11) in an introduction place (13) into a fresh air line (7) of a fresh air plant (...

The valve has a conduit (12) for guiding a medium e.g. exhaust gas, and including walls. A valve unit (20) is arranged in close or open conditions within adjacent walls of the conduit. The valve unit is formed at a curve where a cylinder cut with another c...

The valve assembly (14) for the controlling of a fluid flow in or out of a cylinder (10) of an internal combustion engine has at least two inlet valves (14A,14B) for the entry of the fluid flow into the cylinder and/or at least exhaust valves for the exhau...

The throttle closure has a number of parallel elastic lamella elements (13) extending across the flow cross-section of the suction channel (12) and expanded in height via operating elements (25), so that adjacent lamella elements are brought into contact w...

The valve has a quick-switching flap, with an elastic region (20), stiffened at an edge region (22) by a reinforcing ring (23) or similar. This damps the impact against the seat surface (19) of the channel structure and levels out the tolerances, thus mini...

A charge control device for a reciprocating IC engine, especially a gas engine, containing at least one cylinder (4) in which works a piston is connected to a crankshaft(10). The cylinder has an inlet opening (16) in which an inlet valve (18) works, openin...
