Abstract
An internal combustion engine defining a combustion chamber for the direct injection of fuel through a centrally located fuel injector and having a first inlet passage and port for directing hot exhaust gases of a recirculation medium to a central region of the combustion chamber and a second inlet passage and port for directing air tangentially into the combustion chamber to cause a circular flow about the chamber's periphery and about the exhaust rich central region. The injector sprays fuel through the hot exhaust gas medium in the central region which results in a pre-heating of the fuel which has been found to reduce hydrocarbon emissions prior to ignition by a spark plug located adjacent the periphery of the combustion chamber.
