An engine control system includes one or more oxygen (O2) sensors disposed proximate to a three-way catalytic converter (TWC) in an exhaust system of the vehicle, a nitrogen oxides (NOx) sensor configured to measure an NOx level of the exhaust gas downstre...

A fuel injection valve includes: a needle valve including a seat portion in a front end side; a nozzle body including a seat surface on which the seat portion sits, and including an injection hole at a downstream side with respect to the seat surface; and ...

A fluid injector (1) for a combustion engine is disclosed. It comprises a central longitudinal axis (LA), an injection valve housing (HO) with an injection valve cavity (CA), a valve needle (VN) being axially movable within the injection valve cavity (CA) ...

The present invention addresses the problem that in a fuel injection control system for an internal combustion engine provided with a low pressure fuel pump and a high pressure fuel pump, delivery pressure of the low pressure fuel pump can be decreased as ...

A fuel injection device is equipped with a fuel injection valve that is mounted in an engine body and injects fuel containing air bubbles, and void fraction adjustment means that changes a void fraction of the fuel that is to be injected from the fuel inje...

A fuel injection device is provided with a fuel injection valve to inject fuel into a combustion chamber of an engine, and an electronic control unit to operate the fuel injection valve to inject the fuel in multiple separate injections. The electronic con...

The fuel injection system has a first injection nozzle that is arranged centrally above a combustion chamber (117). A second controllable injector nozzle (101) is arranged in an upper wall or confinement region of the combustion chamber. The homogenous air...
