Abstract
An internal combustion engine, especially of a motor vehicle, is described wherein fuel can be injected into an intake manifold or into a combustion chamber during warm up. A control apparatus is provided for determining a warm-up factor (fWL) for increasing the injected fuel quantity below an operating temperature of the engine. With the control apparatus, the warm-up factor (fWL) is determined from a base factor (fG) and a load-dependent factor (fLA).
