Abstract
The cylinder head to the combustion chamber is provided with a peripheral array of injection nozzles for injection non-igniting fuel into the combustion chamber and a central fuel injection nozzle for injecting an ignition fuel. The openings of the respective nozzles are arranged to inject a distribution of the fuels in the combustion chamber which is symmetrical relative to the cylinder axis. The openings of the peripheral nozzles are disposed to inject fuel transversely into the combustion chamber symmetrically to a plane passing through each respective peripheral nozzle and the central nozzle while the central nozzle has a nozzle opening in each such plane.
