ENGINE STARTER

Japanese Patent JP2015229944

A

PROBLEM TO BE SOLVED: To provide an engine starter capable of realizing shorter engine start time without reducing a motor rush current reduction effect.SOLUTION: An engine starter 1 comprises: a rush-current reduction means 5 reducing a rush current of a motor 6; and starter-characteristic switching means switching characteristics of the engine starter 1 over between characteristics of high torque and low revolving speed and characteristics of low torque and high revolving speed. The starter-characteristic switching means includes a variable speed reduction mechanism unit 7; and a speed-reduction operation switching unit 31 switching a state of the variable speed reduction mechanism unit 7 (over between a reduction mode and a non-reduction mode). The variable speed reduction mechanism unit 7 is set into a reduction mode at a moment of maximum engine friction at least during a first course of passing of a piston over a top dead center in a compression stroke after starting carrying a current to a solenoid SL1, whereby the engine starter 1 exhibits the starter characteristics of high torque and low revolving speed. At a time of cranking an engine after completion of the first course of passing of the piston over the top dead center in the compression stroke, the variable speed reduction mechanism unit 7 is set into a non-reduction mode, whereby the engine starter 1 exhibits the starter characteristics of low torque and high revolving speed.
