Latest Patents

Kevin Walsh holds a patent for an "Engine braking method and control system varying engine braking power within cylinder-number braking mode." This invention includes engine braking actuators that adjust exhaust valve timings to engine braking timings in a cylinder-number braking mode. The system features an engine braking controller that is coupled to a control switch, producing a request indicating the desired cylinder-number braking mode. The controller transitions exhaust valves to the appropriate timings, determines a control term to adjust intake air pressure, and modifies the geometry of an exhaust turbine based on this control term. This results in an adjusted speed of a compressor, which changes the intake air pressure and subsequently adjusts the braking power of the engine. Different levels of braking power are provided within various cylinder-number braking modes.
