  • FUEL INJECTION CONTROL DURING START-UP
    Publication number: 20110186014
    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.

  • METHOD AND SYSTEM FOR ENGINE CONTROL
    Publication number: 20110162620
    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.

  • COOLED EGR SYSTEM FOR COOLANT HEATING DURING COLD ENGINE START
    Publication number: 20110139133
    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. One or more engine operating parameters are adjusted in response to the HP-EGR entering the engine during the cold start in order to maintain combustion stability.
