Abstract
A piston having an offset piston bowl for use in an engine having a correspondingly offset fuel injector, wherein the piston bowl has a non-circular or non-annular shape. The non-annular bowl shape is contoured to permit increased spray plume length, avoiding impingement. The bowl is especially useful in a diesel engine having two-valves per cylinder, wherein the injector must be mounted in an offset location because a central region of the cylinder head is occupied by two proximal valve ports. The bowl has a raised inner portion surrounded by a concave outer portion. A peak or apex of the raised inner portion is located closer to a peripheral wall of the concave outer portion at a 'short' side of the bowl than at a 'long' side of the bowl.
