  • Methods for transient fuel control compensation
    Patent number: 11739708
    Abstract: Methods and systems are provided for an engine for adjusting cylinder parameter settings to optimize engine output during a transient mode. In one example, a method may include adjusting cylinder parameter settings, including a cam timing setting, a spark timing setting, and a fuel injection timing setting based on a chamber temperature in response to a rate of fuel injection acceleration being greater than a positive threshold, thus indicating the engine is in the transient mode.

  • Methods and systems for aftertreatment device
    Patent number: 11725558
    Abstract: Methods and systems are provided for an exhaust system. In one example, a method includes heating an aftertreatment device during an engine off. The heating includes utilizing one or more of an injector, a heater, and a recirculation fan.

  • Method and system for compensating engine thermal conditions
    Patent number: 8731802
    Abstract: A method for compensating for thermal transient conditions of an engine that can cause valve growth or contraction is disclosed. In one example, the method provides cylinder air amount compensation during non-blow-through and blow-through conditions. The approach may improve cylinder air amount estimates, thereby improving engine emissions.

  • Control for alcohol/water/gasoline injection
    Patent number: 8434431
    Abstract: A system for controlling an engine is described. In one example, fuel and a fluid are delivered to the engine cylinder, the fluid including at least some water. The amount of fuel and fluid delivered is adjusted in different ratios as a condition varies to address both pre-ignition and knock.

  • Control for alcohol/water/gasoline injection
    Publication number: 20070119391
    Abstract: A system for an engine of a vehicle traveling on the road, comprising of a cylinder located in the engine, a delivery system configured to deliver fuel and a fluid to at least an engine cylinder while the vehicle is traveling on the road, said fluid including at least some water, and a controller for varying an amount of said fuel and fluid delivered to the cylinder in different ratios as a condition varies, said controller further varying a spark timing of a spark in said cylinder as an amount of water in said fluid varies.

  • Controlling spark of an engine with adjustable intake valve timing
    Publication number: 20060123770
    Abstract: 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 an engine with adjustable intake valve timing
    Publication number: 20060037306
    Abstract: 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.
