Abstract
A heat engine has a starting system comprising two starters so arranged that their pinions engage the starter crown of the engine in parallel once the ignition key is turned. Each starter comprises an electric motor and a power interrupter connected in the power circuit of the motor and controlled by energizing a coil. The closing of the interrupter of one of the starters is delayed with respect to the other one. Reopening of one of the interrupters due to the voltage drop caused by closing the interrupter of the other starter is avoided by appropriate selection of the time delay.
