摘要： A method of controlling start of an internal combustion engine is provided. By the method, supply of fuel and ignition are suspended at the beginning or initial stage of cranking and started for the first time when a cranking speed has become a predetermined value. In a modified embodiment, a time elapsing from the starting of the cranking is measured, and supply of fuel and ignition are started when the time elapsing from the staring of the cranking has become a predetermined value, though the cranking speed does not become the predetermined value. The predetermined value can be altered depending upon battery voltage and coolant temperature. A device for carrying out the method is also provided.
