ABSTRACT:
The invention relates to a process for the injection of fuel into an internal combustion engine, wherein the fuel is firstly enriched in a gas enrichment device (20) with a gas or a gas mixture, in particular oxygen or air. The fuel is atomized and the gas or gas mixture dissolved into the atomized fuel and the enriched fuel is then injected directly into at least one cylinder (12), or indirectly into a preceding region (17), in particular the intake manifold of the engine, with the result of further atomization. The fuel, at least in the enriched state, is cooled up until the final atomization such as to counteract a release of the gas or gas mixture from the fuel before said final atomization. The invention further relates to an injection unit for carrying out said process.
