A system for improving engine performance and emissions is presented. The system can lower exhaust pressure and improve engine breathing. In one example, exhaust gases are combined to reduce exhaust pressure during exhaust valve overlap.

System for improving engine performance and emissions

A system and method for lash adjustment in the valvetrain of an internal combustion engine include a hydraulic lash adjuster having a damping device to limit rate of movement of a plunger relative to a body to control response time of the lash adjuster reducing or eliminating over-compensation or pump-up of the lash adjuster.

Hydraulic lash adjuster with damping device

A system for an engine, comprising a cylinder, a first injection subsystem for injecting a first substance into the cylinder, a second injection subsystem for injecting a second substance into the cylinder, and an electronic engine controller configured to control a plurality of operating parameters of the engine, where the electronic engine controller is configured to cause variation of at least one of the operating parameters in response to a shortfall condition of the second injection subsystem.

Control strategy for engine employng multiple injection types

A system and method to control spark timing of an engine wherein the injection timing of the engine is varied relative to a crankshaft position depending on engine operating conditions. According to the method, spark timing is varied as fuel injection timing varies for at least a portion of the engine operating range. The method can reduce fuel consumption, reduce transient fuel requirements, improve engine performance, and reduce CO emissions, at least under some conditions.

Controlling spark of an engine with adjustable intake valve timing

A system and method to control an engine wherein at least intake valve timing is retarded relative to a crankshaft position depending on engine operating conditions. According to the method, at least a portion of the fuel is injected during the intake valve open period with retarded valve timing. The method can reduce fuel consumption, reduce transient fuel requirements, improve engine performance, and reduce CO emissions, at least under some conditions.
