In order to improve performance and more precise emission controls of an internal combustion engine, there is provided a method of controlling an internal combustion engine, the engine including a variable flow exhaust gas recirculation (EGR) system driven...

A fuel injector assembly (16) is provided which includes a control valve (72) actuated by a piezoelectric actuator (80) acting through a hydraulic amplifier (110) to facilitate pressurization of fluid fuel within the fuel injector assembly for dispersing t...

In a piston engine, end play of the piston pin can be prevented without unduly shortening the pin. In the simplest design (fig. 4), a full length piston pin (22) can have spherical end surface (72) in close clearance spacing relative to the combustion cham...

The motion of a control rod in a fuel injector can be detected by an electrical sensor mounted in the fuel injector housing. The sensor includes an electrical probe, insulated from the injector housing, and having a tip located to be contacted by a shoulde...

A fuel injector assembly for an internal combustion engine including an injector body (20) in fluid communication with a source of fuel and a nozzle assembly (28) through which fuel is dispersed from the fuel injector assembly during an injection event. A ...

A fuel injector assembly (10) for an internal combustion engine including an injector body (20) in fluid communication with a source of fuel and a nozzle assembly (28) through which the fuel is dispersed from the fuel injector assembly during an injection ...

A fuel injection system, comprising a low pressure fuel delivery pump (78) with constant output in fluid communication with a low pressure fuel line; said fuel line connected to an electronic controlled fuel pressure regulator (80) and fuel pressure sensor...
