Internal combustion engine with direct fuel injection

摘要

In an internal combustion engine with direct fuel injection having a piston disposed in a cylinder and a cylinder head which together define a combustion chamber, wherein a fuel injector is mounted in the cylinder head so as to inject fuel into the combustion chamber in a conical pattern whereby the fuel is mixed with combustion air to form a combustible mixture, the cylinder head has a shape around the conical fuel pattern which aids in providing combustible fuel/air mixture at least in an area adjacent the conical fuel pattern where a spark plug with electrodes is mounted such that its electrodes are disposed outside the conical fuel pattern.
