本発明はテイーゼルエンジンのグロープラグを用いた予
熱装置の電子制御装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an electronic control device for a preheating device using a glow plug of a tasel engine.
従来の自動予熱制御装置としては、例えばキースイッチ

ンプを消灯させて予熱か完了したことを表示するように
構成した装置（例えばＮｌ５ＳＡＮサ一ビス周報第６３
７号第１１５頁）がある。Conventional automatic preheating control devices, for example, when a key switch is turned on, energize a glow plug for a energization time that corresponds to the engine cooling water temperature, and also turn on a glow lamp to indicate that preheating is in progress. A device configured to automatically stop energizing when the above energizing time has elapsed, turn off the glow lamp, and display that preheating has been completed (for example, Nl5SAN Service Bulletin No. 63)
No. 7, p. 115).
しかし上記の装置においでは、予熱時間を冷却水温に応

ープラグの抵抗値やワイヤハーネスの抵抗のバラツキや
経時変化及びバッテリ電圧の変動による発熱量の変化を
補正することが出来なかった。However, in the above device, the preheating time is set according to the cooling water temperature (for example, 60 seconds for temperatures below 36°C, 20 seconds for 36 to 70°C).
2 seconds for temperatures above 70°C), it is not possible to compensate for variations in glow plug resistance and wire harness resistance, changes over time, and changes in heat generation due to fluctuations in battery voltage. .
例えば、バッテリ電圧を■３、グロープラグの抵抗ヲＦ
Ｌ。、バッテリとグロープラグとを接続するワイヤノ・
−ネスの抵抗をＲＨとすれば、グロープラグにおける単
位時間当りの発熱量Ｗは、となる。For example, set the battery voltage to ■3, and the glow plug resistance to F.
L. , the wire connecting the battery and glow plug.
- If the resistance of the glow plug is RH, then the amount of heat generated per unit time W in the glow plug is as follows.
（１）式から判るように、バッテリ電圧■３が低下した
り、あるいはグロープラグやワイヤノ・−ネスの抵抗か
大きい場合には、単位時間光りの発熱量が低下するので
、同一の通電時間では、エンジン始動に最適な温度捷で
予熱することが出来ず、始動不良になる事態が生じるお
それがある。As can be seen from equation (1), if the battery voltage (3) decreases or if the resistance of the glow plug or wire connection is large, the amount of heat generated by the light per unit time decreases, so for the same energizing time, the amount of heat generated by the light decreases. In this case, the engine cannot be preheated to the optimum temperature for starting, and there is a risk that the engine will not start properly.
まだ上記の事態を避けるため、通電時間を予め長めに設
定しておく方法も考えられるが、この方法では、不必要
なときも通電時間が長くなるので。In order to avoid the above situation, it is possible to set the energization time longer in advance, but with this method, the energization time becomes longer even when it is unnecessary.
始動が不便であると共にノくノテリの電力消費が大きく
なり、またグロープラグが過熱する機会が多くなるので
寿命が短く力るという問題がある。Not only is it inconvenient to start, but the power consumption of the nokunoteri increases, and the glow plug has more chances to overheat, resulting in a short lifespan.
捷だグロープラグの抵抗値を低目に設定しておけば、バ
ッテリ電圧が低下した場合やワイヤハーネスの抵抗が大
きい場合でも迅速に加熱することか出来るか、バッテリ
電圧等が正営々場合はグロープラグが著しく過熱して寿
命か非常に短くなるので実用的ではない。If you set the resistance value of the glow plug to a low value, it will be possible to heat up quickly even if the battery voltage drops or the resistance of the wire harness is high. This is not practical as the plug will overheat significantly and its life will be extremely shortened.
なおテイーゼルエンジンの予熱制御装置としては特開昭

初に反転する時点との間隔は非常に短いから、どちらを
予熱時間の起点にしても大差はない。In the present invention, the temperature of the glove-lug is maintained at a constant value as described above, and there is no risk of overheating. Therefore, the resistance value of the glow plug can be set to a low value, so even if the battery voltage drops or the resistance value of the wire harness is long, it will heat up rapidly. Therefore, since the interval between the time when the above-mentioned signal S is applied and the time when the signal S8 is first inverted, there is no big difference whichever point is used as the starting point of the preheating time.
