A starting method for a combustion engine 10 of a motor vehicle12, the combustion engine 10 comprising a crank shaft 14, at least one combustion chamber 16 with at least one gas exchange valve 18, at least one injection device 20 for supplying the combustion chamber 16 with fuel for driving the crankshaft 14 and a starting actuator 22 for accelerating the combustion engine 10 from the standstill to an idle speed. The at least one gas exchange valve 18 is kept permanently open while the combustion engine 10 is accelerated from a standstill to a predetermined engine speed, which is different from the idle speed, by means of the starting actuator 22. Alternatively a release valve 19, which is different from the gas exchange valve 18, is kept open while the combustion engine 10 is accelerated. Preferably the injection device is also deactivated during the acceleration to the predetermined engine speed. The method allows for both energy consumption and engine emissions to be decreased. |
