本発明は、デイーゼルエンジンの始動補助装置
であるグロープラグ電圧制御回路に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glow plug voltage control circuit which is a starting assist device for a diesel engine.

ウプラグに流れる電流を一定にする。 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 capacitor charging time, and the energization is stopped when the cooling water temperature exceeds a certain value.Preheating is performed at a higher voltage than when keeping warm to shorten the preheating time.'' The micro film published 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 are kept warm even after the engine has started.'' If the power is turned on until the cooling water temperature reaches a certain value, it will have to be turned on for a long time and a water temperature sensor will be required.Therefore, the power supply will be stopped after a certain period of time from the engine start signal is controlled by a timer. Furthermore, in Japanese Patent Publication No. 1452/1983, it is stated that ``When the engine starts, the battery voltage is detected and one or more of the several resistors connected in series with the glow plug is connected to the glow plug. If it is, short-circuit it to make the current flowing to the glow plug constant regardless of the high or low battery voltage.

装置が記載されている。 Additionally, Japanese Patent Publication No. 48-36126 states that when the voltage applied to the Zener diode rises above the set voltage after the engine starts, the glow plug, which has a glow resistor and display heat transfer wire connected in series, is no longer energized. The device that will be discontinued is described in Japanese Utility Model Application Publication No. 56-8863. If the voltage applied to the glow plug becomes 7V or more after the engine starts due to disconnection or other causes, the output of the comparator becomes "0" and the resistance A device is described for stopping energization to glow plugs connected in series.

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 even faster as the voltage increases. Overheating occurs, causing wire breakage or fusing of the heating coil.

は基本的には、このような技術思想に基づくもの
である。 The power supply for the glow plug heating control circuit is normally provided by the vehicle's battery, but the power supply voltage changes depending on the starting state of the engine. 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 such disconnection or fusing, 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 restart normal heating or All you have to do is switch to rapid heating. The present invention is basically based on such a technical idea.

だけ加熱を中止する。 Next, the operation of the control circuit will be explained. First, when key switch 2 is turned on, starter relay coil RLs is energized, starter relay contact RL 2 is closed, the starter is activated, and the engine starts.
On the other hand, the heating current of the glow plug is generated by the power supply as described above.
E p → Key switch 2 → Relay contact rl 1 → Current detection resistor R e → Glow plug 1 → Power supply E p and flow,
Ultra-rapid heating as shown by curve a in FIG. 3 is started. When the temperature of the glow plug reaches T M in the same figure,
That is, when a predetermined temperature is reached before the preheating set temperature Ts , the voltage between terminals a and b of the bridge circuit exceeds the set value of the comparator C1 , and the comparator C1 outputs an output signal. This output signal passes through an OR circuit 3, is amplified by an amplifier 4, and excites the first relay coil RL1 . Since the contact rl 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 5 outputs an output after the set time has elapsed, and the second relay coil is energized. Activation of the second relay closes its contacts rl 2 and inserts the voltage drop resistor R d in series into the heating current circuit of the glow plug 1. The heating speed is reduced by inserting the voltage drop resistor R d , and the third
Rapid heating occurs as shown by curve b in the figure. The above is the normal operation of the glow plug control circuit. Third
In the figure, to convert from ultra-rapid heating as shown in curve a to rapid heating as shown in curve b,
Although heating is stopped for a time Δt at the set temperature T M , if the set time t of the timer 5 is made smaller, the switching from ultra-rapid heating a to rapid heating b will be performed continuously. By the way, if the engine starts in a short time as shown by curve c in Figure 1 and a high voltage as shown in peak b in the figure is generated, a high heating current will flow through the ultra-rapid heating circuit of the glow plug. The heating coil of the glow plug becomes overheated. Therefore, when a voltage higher than such a steady voltage occurs, the comparator C 2 outputs an output while the high voltage continues, and the first relay is activated and its contact rl 1
Opens the ultra-rapid heating circuit and cuts off the heating current flowing to the glow plug's heating coil due to high voltage.
This prevents accidents such as disconnection or melting due to overheating of the glow plug heating coil. The temperature characteristics of the glow plug at this time are curve c in Figure 3.
The time d t during which high voltage is generated is as shown in
Just stop heating.

For E p , key switch 2, normally closed contact rl 1 of the relay that operates when the temperature of the glow plug exceeds a certain value, and a current detection resistor R having a value of 1/10 or less of the normal temperature resistance of the glow plug e , in an ultra-rapid heating circuit connected in series with a glow plug,
An output signal from comparator C 1 outputs when the temperature of the glow plug exceeds a certain value, and a comparator C 2 outputs when the power supply voltage exceeds a steady voltage value. Since the relay was activated by a signal and the ultra-rapid heating circuit was opened, there was no possibility of disconnection due to overheating of the heating coil due to the sensitivity of the glow plug to power supply voltage fluctuations due to the adoption of ultra-rapid heating. Alternatively, durability deterioration such as melting can be prevented, and since the voltage is constantly monitored while the glow plug is energized regardless of the heating rate, the glow plug can be reliably protected. In addition, the resistance of the voltage setting device 6
Since the set voltage can be arbitrarily set by R s , an accurate set value can be obtained even if the characteristics of the Zener diode are not constant.
