摘要： In known starting devices, an individual starter is provided which accelerates the internal combustion engine to only a relatively low rotational speed at which an initial injection with subsequent combustion takes place. During a cold start of the internal combustion engine, it is therefore absolutely necessary to provide a relatively rich fuel/air mixture for the initial injection. However, this results in a situation in which, during this phase, relatively high exhaust gas emissions, in particular of hydrocarbons, are produced, which cannot be controlled by a catalytic converter which is not yet at its operating temperature. In order to reduce the exhaust gas emissions, a starting device for an internal combustion engine is proposed which has two starters for starting the internal combustion engine, a first starter being activated at the beginning of the starting process and being deactivated after a specific rotational speed of the internal combustion engine has been reached, a second starter (2) being activated. The second starter subsequently drives the internal combustion engine further to a specific setpoint rotational speed, after which, when the setpoint rotational speed has been reached, an initial injection of fuel for subsequent combustion is carried out. The starting device according to the invention is provided for internal combustion engines of vehicles.
