The air suction channel system is particularly for V-cylinder vehicular internal combustion engines and involves a housing part (10) forming at least a part of the air channels and supporting shutters (20) in an air channel, at least two of which have a co...

An intake air control device (20) for internal combustion engines includes a valve member (10, 10A) disposed within an intake air channel (3) of the internal combustion engine. The valve member is operable to open and close the intake air channel. An orifi...

An integrated intake manifold assembly (10) including a first poppet valve assembly (16) disposed at the air inlet (96) to the manifold (12) to regulate air flow into the manifold; a second poppet valve assembly (20) disposed on the manifold to regulate ex...

The device has a control element located in front of the valve seat in flow direction, with an active surface to influence the suction channel profile. The control element (2) is mainly ring-shaped and moves eccentrically around the longitudinal suction ch...

An intake device (100) of an internal combustion engine (1) is provided that includes an intake flow control valve (29) shaped so as to be capable of effectively forming a tumble flow within a combustion chamber (14) when there is a projection (27a) within...

The method of combustion control for an internal combustion engine (PS) involves measuring the ionization flow of the combustion gases (6) to regulate a turbulence generator using commands dependent on the flow values. The cylinder pressure dependent on th...

The internal combustion motor, with direct fuel injection, has at least one air intake channel (12) for the air feed into a cylinder (10). At least one inlet valve (13) and injection valve (14) are in the channel. A switch unit (15) in the air intake chann...

The mixture formation arrangement for an internal combustion engine has a metal fuel distributor strip feeding fuel under high pressure to individual injection nozzles and air suction channels leading to a cylinder head from a suction pipe. The metal fuel ...

In a port fuel injection lean burn engine, attaching of fuel spray onto a wall surface, which is a problem at atomizing injected fuel, is reduced, and the quality and shaping state of the mixed gas in cylinders of the engine is improved. The engine compris...
