Abstract
A method of starting a multi-cylinder, direct-injection, internal combustion engine of a motor vehicle in particular without using a starter motor is described. The position of a piston in a cylinder of the internal combustion engine is determined, and fuel is injected into a combustion chamber of the cylinder whose piston is in a working phase, and the fuel is ignited immediately thereafter, thus triggering the starting operation. To improve the processing of the mixture during the starting operation, as the starting operation continues, immediately after ignition of the fuel in the cylinder which is in the working phase, fuel is injected into a combustion chamber of another cylinder whose piston is in an intake phase, and the injected fuel is ignited while still in the intake phase.
