起動モータ２はオフし、エンジン１から切り離さ
れる。 First, when the start switch 11 is turned on, the power is connected to the control device 8, the start delay is turned on, and a start command and a start rotation speed command are input to the control device 8. After a predetermined time, the relay of the ignition system 9 turns on, and the push delay starts from the ignition system on.
After T 0 , the starting motor 2 is turned on. That is,
The starting motor 2 first has a drive pinion pushed into the ring gear of the engine 1 after a pushing delay T 0 , and then after a starting motor delay T 1 the pinion of the starting motor 2 rotates for a time T 2 . The rotation of the pinion of the starting motor 2 causes the engine 1 to
When the crankshaft rotates and its rotational speed reaches N1 , the fuel valve 6 opens and fuel gas is supplied to the combustion chamber, so the engine starts. When the rotational speed of the engine under its own power reaches N2 , the starting motor 2 is turned off and disconnected from the engine 1.

弁６を閉弁した後、再びフローの最初に戻り起動
デイレーを再度オンして上記操作を繰り返す。 After the starting motor 2 is turned off, the engine 1 further increases its rotation speed from N 2 to the specified starting rotation speed N 3 due to its own rotation. The number of revolutions of this engine 1 is N 2
The above rotation will take some time after starting motor 2 is turned off.
If the engine continues for a period of time T 3 , and during that time rises to the specified rotation speed N 3 at startup, and maintains that rotation speed N 3 , the load application timer turns on only in that state, and after time T 4 . The load input device 3 is turned on and the load is connected. Here, if the rotation speed of the engine 1 does not continue at N 2 or higher for T 3 hours and the rotation speed decreases, the load application timer will not turn on, and after closing the fuel valve 6, the engine will restart at the beginning of the flow. Turn on the return start delay again and repeat the above operation.

場合にはエンジン停止に至ることがある。 As described above, when the load input device 3 is turned on and the load is connected, the operating speed switching timer is turned on at the same time, and after time T5 , the engine speed is
Starting command rotation speed N 3 to specified rotation speed during normal operation
It is switched to N 4 and operated under control such that N 2 <N 4 ≦N 3 . In this case, when the above-mentioned load is applied, the engine is subjected to a sudden load and the rotational speed temporarily decreases, so the steady operating rotational speed decreases as soon as the load is applied.
When switching to N 4 , it is difficult to make a smooth switch and the steady rotational speed N 4 becomes disturbed. In the worst case, the engine may stop.

なみに利用することを可能にする。 As described above, the internal combustion engine starting control device according to the present invention controls the number of revolutions per unit time of the internal combustion engine, which is equipped with a starting motor and a load application device that turns on and off the connection with the load. A sensor is provided to detect the engine speed, and the load application device is turned on and off via a control device based on the rotational speed signal detected by the sensor, and the starting motor is turned on while the load application device is off to start internal combustion. After the engine is started and the starting motor is turned off, the rotational speed detected by the sensor is greater than or equal to the specified rotational speed N2 for a specified period of time T3.
Continuing the above, the load application device is turned on only when the specified rotation speed at startup increases to N 3 , and after a specified time T 5 or more has elapsed since the load application device was turned on, the specified rotation speed at startup N 3 decreases to the steady operation rotation speed. Since the control is made to switch to N4 , the startup of the internal combustion engine is ensured until the load is connected, making it possible to use the internal combustion engine as much as an electric motor.
