Abstract

The invention is directed to a method of starting an engine for internal combustion engines of a motor vehicle driven by gasoline direct injection with the engines being subdivided into several cylinder banks and a high pressure injection system being provided for each cylinder bank. During a first phase (A), an injection into the cylinders of a first cylinder bank in correspondence to their normal ignition sequence takes place and no injection is carried out in the cylinders of the remaining cylinder banks. In a subsequent second phase (B), injection takes place also into the cylinders of the other cylinder bank or banks.
