Internal-combustion engine e.g. petrol engine or diesel engine, starting method for vehicle, involves activating electric motor after stopping phase, and determining mixture enrichment after exceeding starting rotational speed

摘要

The method involves activating an electric motor (12) after a stopping phase, and bringing an internal-combustion engine (2) e.g. petrol engine, to a starting rotation speed by the electric motor. The engine is brought to a desired rotational speed by the electric motor in a trailing phase, where the desired rotational speed lies above the starting rotational speed. Mixture enrichment is determined after exceeding the starting rotational speed. A fuel measurement takes place based on the mixture enrichment, after reaching the desired rotational speed. Independent claims are also included for the following: (1) a controller for controlling and regulating an internal-combustion engine (2) a computer program, which is executable on controller, for controlling and regulating an internal-combustion engine.
