ABSTRACT:
An internal combustion engine having at least one cylinder, each cylinder including an open chamber permanently connected with a separate chamber. A small portion of the fuel charge is injected in the separate chamber, where it vaporizes, mixes with air, the fuel-air mixture being electrically ignited. The remaining portion of the fuel charge is injected in the open chamber into the burning gases ejected from the separate chamber. Both fuel injections are achieved by the same injection pump. The fuel charge of the separate chamber is accumulated in the injector of this chamber during the fuel injection in the open chamber, and is injected in the separate chamber during the next cycle.
