ABSTRACT:
A direct injected, internal combustion engine combustion chamber configuration and injection control strategy. Stratification is accomplished by providing a piston bowl and air flow pattern within the combustion chamber through intake passage shape and squish action. The shape of the combustion chamber also provides rapid flame propagation even at low speeds and loads. The timing of injection of fuel from the fuel injector is such that under low speed/low load conditions the injector begins its injection at a time when the piston is at the end of its compression stroke and under other running conditions the fuel injector begins its injection during the intake stroke
