なければならない煩わしさがあつた。 Since this warm-up operation is normally performed under no-load conditions, the time cannot be shortened, and there are also several disadvantages such as the generation of unburned gas due to incomplete combustion.
In order to solve this problem, the applicant invented a warm-up promotion method and device, and
A patent application was filed using Publication No. 45494. This acceleration method uses an electromagnetic retarder to apply a predetermined load after the diesel engine starts, thereby speeding up the temperature rise and shortening the warm-up time. In order to cause the engine to stop, the driver must manually prevent the engine from stopping by depressing the accelerator pedal connected to the load lever of the fuel injection pump.

る。 FIG. 1 is a block diagram of an apparatus according to an embodiment of the present invention.
The device of this embodiment includes a flywheel 3 which is a magnetic rotor mounted on a crankshaft 2 of a diesel engine 1, a retarder unit 5 and a fuel injection pump 6 attached to the flywheel housing 4.
This load lever 7 is connected to the load lever 7 of
a solenoid 8 which is an electromagnetic drive means for displacing the fuel so as to increase the amount of fuel injected;
The electric circuit includes a battery 9 that supplies current to the retarder unit 5, and a retarder switch 10 that interrupts the current flowing through the solenoid 8 and the retarder unit 5.

付けられている。 The retarder unit 5 is formed by an excitation coil 12 for applying magnetic force to the teeth 11 and a shorting ring 13 for short-circuiting a current generated due to a change in the lines of magnetic force between the teeth 11 and the teeth 11. A plurality of retarder units 5 (eight in this example) are attached to the flywheel housing 4.

せ、暖機運転を促進させる。 By turning on the retarder switch 10, an excitation current flows through the excitation coil 12, generating lines of magnetic force and forming a magnetic circuit with the teeth 11 of the flywheel 3, which is a magnetic rotor, so that they are attracted to each other. Therefore, it acts as a braking force for the flywheel 3 that is about to rotate. This braking force becomes a load on the diesel engine. Furthermore, as the crankshaft 2 rotates, the teeth 11 of the flywheel 3 move one after another relative to the core 14 inside the excitation coil 12, so the lines of magnetic force change and the short-circuit ring 1
A current is generated in the short-circuit ring 13, and this current turns into heat in the short-circuit ring 13, raising the temperature of the diesel engine 1 in a short time and promoting warm-up operation.

ぐことができる。 At the same time, a current flows through the solenoid 8 connected to the load lever 7 of the fuel injection pump 6, and this solenoid 8 is energized to move the load lever 7 in the direction of fuel increase, thereby reducing the speed of the diesel engine, which is about to decrease due to the warm-up promotion effect. Automatically increase rotation speed. As a result, even if the retarder is activated to reduce the engine rotational speed during warm-up operation, the fuel injection amount is automatically increased, thereby preventing the engine from stopping.
