摘要： An internal combustion engine piston having a combustion bowl with fuel control structure for redirecting at least a portion of the fuel exiting the combustion bowl. One form of the piston includes a sharp edge disposed at the outer surface of the piston adjacent the entrance to the combustion bowl and a rounded fuel receiving lip located within the combustion bowl.

摘要： An air intake heater system for internal combustion engines is disclosed including a microprocessor controller, intake manifold air temperature sensing means, water in fuel sensors, electrical air heating elements actuated by the microprocessor, and system status indicators. Additionally, fuel injector timing is altered by the microprocessor depending upon intake manifold air temperature. Air intake heating is provided to assist cold weather starting of engines as well as for minimizing white smoke pollutants produced by diesel engines. Power consumption of the device is maintained below a predetermined level by judicious use of the microprocessor controller in conjunction with the electrical heating elements.

摘要： 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.
