  • Patent number: 8297255
    Abstract: Methods and systems are provided for controlling exhaust emissions by adjusting a fuel injection into an engine cylinder from a plurality of fuel injectors based on the fuel type of the injected fuel and further based on the soot load of the engine. Soot generated from direct fuel injection is reduced by decreasing an amount of direct injection into a cylinder as the engine soot load increases.

  • Publication number: 20120239277
    Abstract: Methods are provided for operating an engine with a variable fuel blend in a cylinder, where the variable fuel blend varies a peak achievable engine torque for a given operating condition. One example method comprises selectively operating an engine actuator that affects engine torque and engine fuel economy at the given operating condition, and extending operation of the actuator to higher engine torques as a peak engine torque for the given operating condition increases.

  • Publication number: 20120227382
    Abstract: Various systems and method are described for controlling an engine having an exhaust system which includes a particulate filter. One example method comprises, after shutting down the engine and spinning down the engine to rest, operating a vacuum pump to draw fresh air through the exhaust system to an intake system, and regenerating at least a portion of the particulate filter during the engine rest.

  • Patent number: 8240294
    Abstract: Various systems and method for heating an engine in a vehicle during a cold start are described. In one example, thermal efficiency of the engine is improved by heating engine coolant via a high-pressure exhaust gas recirculation (HP-EGR) system. For example, after light-off of an exhaust catalyst, exhaust gas is routed through the HP-EGR system which includes a HP-EGR cooler. Heat from the exhaust gas is then used to warm the engine coolant via the HP-EGR cooler.

  • Publication number: 20120203443
    Abstract: Systems and methods of operating an engine, the engine including an injector configured to directly inject fuel into an engine cylinder. One example method comprises, during an engine cold start, performing compression direct fuel injection, and retarding a timing of the compression injection as a fuel alcohol content of the fuel increases.

  • Publication number: 20120165155
    Abstract: A multi-mode internal combustion engine is described. As one example, the engine may be transitioned between a two stroke mode and a four stroke mode in coordination with a transmission shift by adjusting a number of strokes performed by the engine per combustion cycle while shifting the transmission between different gear ratios. Under select conditions, the number of strokes performed by the engine per combustion cycle may be reduced while shifting the transmission from a higher gear ratio to a lower gear ratio. Under other conditions, the number of strokes performed by the engine per combustion cycle may be increased while shifting the transmission from a lower gear ratio to a higher gear ratio.

  • Patent number: 8166952
    Abstract: A method of operation of an internal combustion engine including an intake valve coupled to a combustion chamber, and a port fuel injector positioned upstream of the intake valve in an intake manifold including a throttle, the port fuel injector fluidly coupled to a fuel rail included in a fuel delivery system housing a fuel at least partially composed of alcohol. The method including, during a start-up operation when the temperature of the engine is below a threshold value and fuel is actively being injected into the intake manifold, adjusting a cone angle of a fuel spray from the port fuel injector, via adjustment of the throttle and/or fuel delivery system, based on the position of the intake valve.

  • Patent number: 8096920
    Abstract: An approach is described that coordinates transmission shifting with changing between two-stroke and four-stroke combustion to improve shift and drive performance. In one example, responsive to a driver tip-in, the system may transition the engine to a two-stroke combustion mode from the four-stroke mode and increase a transmission gear ratio in order to avoid transmission shifts during the subsequent acceleration.
