ものが記載されている。 For example, Japanese Patent Application Laid-open No. 55-101771 states, ``In order to improve the startability of a diesel engine at low temperatures, suppress the generation of black smoke, and prevent the engine from stopping, the glow plug is continuously energized to keep it warm even after the engine has started.'' The energization time is controlled by the charging time of the capacitor, and the energization is stopped when the cooling water temperature exceeds a certain value.In addition, preheating is performed at a higher voltage than when keeping warm to shorten the preheating time. The microfilm in Utility Model Publication No. 56-13552 states, ``In order to improve the startability of diesel engines at low temperatures, suppress the generation of black smoke, and prevent engine stoppage, glow plugs continue to be used even after the engine has started.'' The power is turned on to maintain heat. If the power is turned on until the cooling water temperature reaches a certain value, the power must be turned on for a long time, and a water temperature sensor, etc. is required. Therefore, the power supply is stopped after a certain period of time has been controlled by a timer from the engine start signal. '', and furthermore, in Japanese Patent Publication No. 1452/1984, it is stated that ``When the engine is started, the battery voltage is detected and the battery voltage is lowered by one or more of several resistors connected in series with the glow plug.'' If it is, short-circuit it to keep the current flowing through the glow plug constant regardless of the level of battery voltage.''

線又は溶断等の原因となつている。 Conventionally, the air near the preheating plug in a part of the combustion chamber was preheated over a preheating time of 5 to 7 seconds until it reached the preheating set temperature (approximately 900°C). At this level of preheating speed, even if the power supply voltage increased slightly, the preheating speed only increased slightly and did not have much of an effect. However, for drivers who are accustomed to gasoline-fueled engines, it is unbearable to wait 5 to 7 seconds for preheating before starting the engine, and it is desirable to shorten the preheating time. In order to meet this demand, the preheating speed has been improved, that is, the resistance value of the heating coil of the glow plug has been extremely reduced and the heating current has been increased to achieve ultra-rapid heating. However, when ultra-rapid heating is performed by extremely reducing the resistance of the heating coil, the heating of the glow plug becomes extremely sensitive to changes in the power supply voltage, and the heating speed becomes too fast as the voltage increases. , causing disconnection or melting of the heating coil.

基本的には、このような技術思想に基づくもので
ある。 The power source for the glow plug's heating control circuit is usually the vehicle's battery, but the power source voltage changes depending on the engine starting condition. For example, as shown in FIG. 1, if it takes a long time to start the engine, the power supply voltage gradually returns to the steady voltage over time as shown by curve a. However, when the engine is started in a short time, the voltage not only returns to a steady state in a short time as shown by curve c, but also increases rapidly as the engine speed increases, generating a high voltage as shown at peak b. Such high voltage leads to overheating of the heating coil of the ultra-rapid heating glow plug, causing wire breakage or melting. Therefore, in order to prevent this disconnection or melting, it is necessary to detect such high voltage, cut off the heating current of the ultra-rapid heating circuit while the high voltage continues, stop ultra-rapid heating, and resume normal heating or rapid heating. All you have to do is switch to . The present invention is basically based on such a technical idea.

熱を中止する。 Next, the operation of this circuit will be explained. First, when key switch 2 is turned on, starter coil RL 2 is energized, starter relay contact γls is closed, the starter starts, and as mentioned above power supply Eo → key switch 2 → normally closed contact γl 1 of the first relay → current detection resistor A circuit is formed from Re to the glow plug to the power source Eo, and a heating current flows through the glow plug, starting ultra-rapid heating as shown by curve a in Figure 3. As the glow plug is heated and its temperature rises, the resistance Rg of the heating coil also increases, and at the same time, the voltage at the a terminal of the bridge circuit also increases. When the temperature of the glow plug reaches the predetermined temperature at point T M in Fig. 3, that is, before the preheating set temperature Ts, the voltage between terminals a and b of the bridge circuit will exceed the set value of comparator C1 . Comparator C1 provides an output signal. This output signal is
It passes through the OR circuit 3 and is amplified by the amplifier 4, and excites the first relay coil RL1 . Since the contact γl 1 is opened by the operation of the first relay, the heating current is cut off and the ultra-rapid heating is stopped. Subsequently, after the key switch 2 is turned on, the timer outputs an output after the set time and excites the second relay coil. Second
Activation of the relay closes its contact γl 2 and inserts the voltage drop resistor Rd in series into the heating current circuit of the glow plug. By inserting the voltage drop resistor Rd, the heating speed is reduced, resulting in rapid heating as shown by curve b in FIG. The above is the normal operation of the glow plug control circuit. In Fig. 3, in order to convert from ultra-rapid heating as shown in curve a to rapid heating as shown in curve b, heating is stopped for a period of Δt at the set temperature T M , but the setting of timer 5 is When time t is decreased, ultra-rapid heating a changes to rapid heating b.
The switching to Δt becomes 0 and is performed continuously. By the way, the engine curve c in Figure 1
If the startup occurs in a short period of time, as shown in curve b, and a high voltage is generated as shown in curve b in the figure, a high heating current will flow through the glow plug's ultra-rapid heating circuit, causing the glow plug's heating coil to overheat. It happens. Therefore,
When such a voltage higher than the steady voltage occurs, the regulator 6 outputs an output while the high voltage continues, the first relay is activated, and its contact γl 1 opens the ultra-rapid heating circuit, causing the glow plug to generate heat due to the high voltage. Cuts off the heating current flowing through the coil. This prevents breakdowns such as disconnection and melting due to overheating of the glow plug heating coil. The temperature characteristics of the glow plug at this time are as shown by curve c in FIG. 3, and heating is stopped for the time dt during which high voltage is generated.

For Eo, the key switch 2, the normally closed contact γl 1 of the relay that operates when the temperature of the glow plug exceeds a certain value, the current detection resistor Re having a value of 1/10 or less of the normal temperature resistance of the glow plug, In an ultra-rapid heating circuit connected in series with a glow plug, the output signal of the comparator C1 , which outputs an output when the temperature of the glow plug exceeds a certain value, and the output of the alternator are connected to the steady voltage of the power supply. Compare and set the regulator to output when it is abnormally high,
