CONTROL OF SPARK IGNITED INTERNAL COMBUSTION ENGINE |
摘要 |
There is provided, in one aspect of the present description, a method of controlling a spark ignited internal combustion engine having a fuel injector which injects fuel directly into its combustion chamber. The method comprises stopping the fuel injection if a desired torque for the engine is a predetermined torque or less and a speed of the engine is a predetermined speed or greater. The method comprises resuming the fuel injection by injecting a first amount of fuel directly into the combustion chamber during a negative pressure period and injecting a second amount of the fuel into the combustion chamber during an intake period. The method further includes resuming the fuel injection by injecting a third amount of the fuel directly into the combustion chamber during the negative pressure period and injecting a fourth amount of the fuel into the combustion chamber during the intake period.
