A system and method for widening auto-ignition range of a lean burn internal combustion engine employs stratified charge of exhaust gas content and air content. A fuel injection system carries out a first injection of gasoline fuel for dispersion within th...

A system and method controls auto-ignition of gasoline fuel within a cylinder of an internal combustion engine by varying an exhaust gas retaining duration. A generator provides a parameter indicative of combustion event within the cylinder. An engine cont...

A homogeneous-charge, compression-ignition engine (10) having engine coolant, an intake manifold and an exhaust manifold including a controller for advancing and retarding auto-ignition in the combustion chamber of the engine, the intake manifold providing...

An enhanced auto-ignition in a gasoline internal combustion engine, comprises a fuel injector directly communicating with said combustion chamber for spraying gasoline fuel. The fuel injector sprays a first injection quantity of gasoline fuel into a combus...

The invention relates to a cylinder injection engine including a fuel injector (6) for injecting a fuel into a combustion chamber formed between a cylinder head and a piston (40), an intake port opening to the combustion chamber, an intake valve (41) dispo...

A compression self-ignition gasoline engine includes a stratifying device stratifying gas in a combustion chamber of the engine, a fuel injector directly injecting fuel in the combustion chamber and a controller connected to the stratifying device and the ...

The control procedure, for use on a multi-cylinder 4-stroke engine with each cylinder (1) having at least one inlet (2) and exhaust (3) duct, consists of taking a quantity of the exhaust gas from one cylinder when the engine is under partial load and trans...
