In the process of starting by a recoil starter, a maximum value detection section of an ECM detects a maximum value of pressure (basic atmospheric pressure) in an intake pipe detected by a pressure sensor, within a predetermined range of crank angle after ...

Engine starting performance is enhanced by a brushless motor (3a) having no rotor position detecting sensor. In the first place an engine (2) is rotated forward and then is reversely rotated to overcome a high load region of the engine. Then, the engine is...

A process for determining the end of the starting phase of a combustion engine (32) started by an electric motor (34) through an accelerated freewheel uses data from the electric motor to determine the injection threshold. Independent claims are also inclu...
