When nature reversing not occurring but in the state of dynamic or the angle critical reversing angle of deficiency is reversed naturally, step is performed
Suddenly (D) judges whether bent axle 31 is stopped in a starting angular interval, if then performing step (E), if not
Or then perform step (F) without angular interval information is started.Wherein, it is described to start angular interval in the present embodiment
It is 0 degree to 120 degree to be, is not limited thereto, if the angle position of bent axle 31 in above-mentioned interval can be without subtracting
Press and directly rotate forward starting engine 30.That is, the position that bent axle 31 is stopped can overcome the using inertia is operated
First compression impedance, execution step (E) directly drives the motor 23 and just goes under without the start of decompressor 32
Starting speed, and perform step (G).
Relatively, if above-mentioned bent axle 31 is not starting in angular interval, the reversion of step (F) bent axle 31 one is performed
Drive motor 23 just goes to starting speed again after specific reversing angle, and performs step (G).Wherein, it is described
It is 90 degree that specific reversing angle is in the present embodiment, is not limited thereto, and is started and the dress that generates electricity as driving
Put 20 reversions and trigger the door angle value of decompressor.That is, the position that bent axle 31 is stopped is at 120 degree
Cannot overcome the first second compression impedance using inertia is operated in 720 degree, therefore, start and TRT 20
Can invert one it is specific reverse angle after again drive motor 23 just go to starting speed, this it is specific reversing angle be true
The unlatching of decompressor 32 is protected, and has driven the motor 23 to rotate forward.
Then, step (G) stops driving, into power generation mode.Now, represent and start and TRT 20
It has been successfully driven engine 30 to start, power generation mode can have been entered.
