ABSTRACT:
A direct injection engine has a fuel injection valve that directs a spray of fuel to each side of a spark plug electrode. The fuel mixes with the air to define a region of relatively richer air-fuel mixture and a region of relatively leaner air-fuel mixture. The electrode is positioned within the relatively leaner region.
