  • Combustion Method for Piston Combustion Engines
    Publication number: 20140216406
    Abstract: A combustion method for reciprocating internal combustion engines, in particular diesel engines, whose fuel injection system operates with pre-injection involves two pre-injections during a cold start phase, which are carried out prior to reaching top dead center of a piston. A first pre-injection is performed at approximately 25° CA before top dead center and a second pre-injection is performed at approximately 5° CA before top dead center. A crank angle interval ? of approximately 20° CA between the individual pre-injections and a crank angle interval ? of approximately 5° CA between the second pre-injection and a main injection, are maintained independently of the rotational speed.

  • Air-compressing internal combustion engine with self-ignition, with a main combustion space and an insert adjoining the latter, accommodated in the cylinder head and having an antechamber
    Patent number: 5105781
    Abstract: An air-compressing internal combustion engine with oblique injection into an antechamber having a sphere-like combustion space and conduit of arranged offset relative to one another. A spheroid impact head with a cup shaped recess on the underside thereof facing the conduit is provided in the lower half of the combustion space. A glow plug is arranged in the downward current of the air flow downstream of the injection nozzle in the antechamber.
