Abstract
An in-cylinder injection, spark ignited internal combustion engine including a fuel injection valve spraying fuel substantially in a sector having a relatively small thickness and spreading substantially vertically to implement homogenous combustion and stratified combustion, ensures that for stratified combustion a large portion of the sprayed fuel is injected into a cavity and thus sufficiently vaporized and positioned as a combustible air fuel mixture in a vicinity of an ignition plug. A fuel injection valve is arranged at a perimeter of an upper portion of the cylinder and a piston has a top surface provided with a cavity biased in location to be farther from the fluid injection valve and having a wall opposite the fuel injection valve deviating toward the cylinder's substantial center the fuel sprayed for stratified combustion through the fuel injection valve into the cavity.
