    摘要： A method for starting an engine of a motor vehicle, the engine having an intake manifold, an intake throttle controlling admission of air into the intake manifold, and a plurality of combustion chambers communicating with the intake manifold, the method comprising providing a reduced pressure of air in the intake manifold prior to delivering fuel or spark to the engine, the reduced pressure of air responsive to a temperature of the engine; delivering fuel to one or more of the plurality of combustion chambers in an amount based on the reduced pressure of air; and delivering spark to the one or more combustion chambers to start the engine.

    摘要： Various methods are described for controlling engine operation for an engine having a turbocharger and direction injection. One example method includes performing at least a first and second injection in response to a driver action. The first and second injection may be performed during a cylinder cycle, the first injection generating a lean combustion and the second injection injected after combustion such that it exits the cylinder unburned into the exhaust upstream of a turbine of the turbocharger.
