Process and system for starting a direct-injecting internal-combustion engine as well as motor vehicle
Abstract:
A process for starting a direct-injecting internal-combustion engine is disclosed. The process includes triggering a separate drive for adjusting the camshaft for causing an angular position change between the crankshaft and the camshaft until the separate drive rotates the crankshaft such that a working medium is compressed by a piston in a cylinder of the internal-combustion engine. The position of the pistons of the internal-combustion engine is determined by using position determining devices to identify the cylinder of the internal-combustion engine in which the working medium is compressed. Fuel is injected into the cylinder in which the working medium is compressed when the cylinder is in a proximity of an upper dead center to start the internal-combustion engine.
