Abstract:
A direct injected, internal combustion engine comprised of a cylinder defining a cylinder bore, a piston reciprocating in said cylinder bore, a cylinder head closing one end of said cylinder bore and forming with said piston and cylinder bore a combustion chamber, at least a pair of intake ports formed in said cylinder head substantially on one side of a plane containing the axis of said cylinder bore, said intake ports being served by an intake passage arrangement that terminates at said intake ports, a pair of intake valves for controlling the flow through said intake ports, a spark plug having its spark gap disposed substantially at the center of said combustion chamber when at its clearance volume condition, a fuel injector mounted in the area adjacent the outer periphery of said cylinder bore and having its discharge nozzle disposed at the side of said intake ports for directly injecting fuel into said combustion chamber, and means for diverting the fuel sprayed by said fuel injector toward said spark plug gap at the time of firing in a stratified relation under at least one engine running condition and for directing the fuel spray under high speed, high load conditions to achieve a homogeneous mixture in said combustion chamber at the time said spark plug is fired.
