ABSTRACT:
A direct cylinder injected internal combustion engine that is effective to provide a stratified stoichiometric mixture at the spark gap at the time of firing and also a homogenous mixture under high speed high load conditions. This is achieved without specially formed bowls in the head of the piston by creating tumble under low speed and lower load conditions and by spraying on the heads of the intake valves during high speed high load conditions to obtain a homogeneous mixture.
