Method for cold starting an internal combustion engine operating with an ethanol fuel, with ignition controlled by a control unit including a basic ignition advance map determined for a given engine, includes the following steps applied to at least one combustion chamber in contact with a piston connected to a drive shaft: determining the engine temperature; rotating the drive shaft; phasing the engine; ensuring the fuel pressure exceeds a determined threshold for injection; injecting fuel for a first operational engine cycle after phasing; below a determined engine temperature, increasing, in the first operational cycle, the advance of the first ignition point before the compression top dead centre for gases in the cylinder, with respect to the advance map, by a value between 21° and 50°; controlling a first ignition point according to advance map based on the cycle following the first cycle. |
