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 α of approximately 20° CA between the individual pre-injections and a crank angle interval β of approximately 5° CA between the second pre-injection and a main injection, are maintained independently of the rotational speed. |
