    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.
