In a two or four cycle reciprocating internal combustion engine, an intake section is defined in the combustion chamber wherein a stratified charge of a rich fuel-air mixture is established in close proximity to the intake valve and the spark plug. An exhaust section also is defined within the combustion chamber and is connected with the intake section through a passage of restricted cross section. Fuel is injected into the intake manifold of the engine through a low pressure fuel injector during an optimum period of the crankshaft rotation. The operable excess air ratio may be adjusted by varying the position of the intake section with relation to the cylinder axis.
