Abstract

PURPOSE:To eliminate watt consumption for only temperature detection of a glow plug, by cutting off a switching element at the upper limit value of temperature in the glow plug, while contributing the glow plug so as to be energized with power at the elapse of time corresponding to a detection value of engine temperature. CONSTITUTION:When a transistor Tr7 is turned to ON by operation of a processing circuit 11 at a certain time, a plug G (consisting of G1-Gn) is heated. And, temperature in the glow plug G reaches an upper limit value theta13 beyond fuel ignitable temperature theta11 and an lower limit value theta12 in a control temperature range, the transistor Tr7 is turned to OFF from the output of a temperature detecting circuit 12 receiving voltage at both ends of a temperature detecting resistor 4. And, simultaneously a timer 15 is set in motion via a trigger circuit 14, and the timer 15 starts its clocking operation of time W corresponding to the output of a cooling water temperature detecting element 8. And, after the elapse of the time W, the transistor Tr7 is turned to ON again via the driving circuit 17 whereby the glow plug G is kept within temperature ranges theta12- theta13.

この範囲で病精度の制御が行なわれなければならない。Background Art When preheating the sill of an easel engine using a glow plug 1, in order to shorten the preheating time and speed up the start, the control temperature range of the glow plug and the electric power supplied to the glow plug must be adjusted. It is necessary to set it to an optimal value. The control temperature range of the glow plug is determined by the heat resistance of the glow plug and the ignition temperature of the fuel. If you raise the temperature of the glow plug too high and it overheats, it will destroy the glow plug. Also, the temperature of the glow plug may be too low.
It is not possible to improve fuel ignitability. Therefore, the control temperature range is set around the temperature at which fuel ignition is good.
Disease accuracy must be controlled within this range.

Therefore, it is desirable to reduce the amount of power supplied to the glove 2 as much as possible.

When starting the diesel engine, the processing circuit 1 such as a microcomputer turns on the main relay 2 at time L1 in FIG. As a result, electric power from the battery 3 mounted on the vehicle is applied to the glow plug G through the temperature detection resistor 4. In this way, the temperature of the glow plug G increases. The voltage across the temperature detection resistor 4 is detected by the processing circuit 1. The glow plug G has a positive temperature coefficient, and the current flowing through the glow plug G decreases as the temperature increases. The temperature detection resistor 4 has a low resistance value of, for example, about 10 mΩ, and the temperature of the goo-plug G can be detected by detecting the voltage of the temperature detection resistor 4. The temperature of this glow plug G rises and exceeds the temperature θ1 at which fuel can be ignited, and the lower limit value θ of the control temperature range is reached.
2 and further reaches its upper limit value θ3, the processing circuit 1 shuts off the main relay 2. Therefore, the auxiliary relay 5 is always turned on by the processing circuit 1 at the time of starting. Therefore, when the main relay 2 is cut off, the current from the battery 3 is transferred from the current detection resistor 4 to the glow plug GI via the auxiliary relay 5 and the protective resistor 6.
:@Reru. This allows the temperature detection resistor 4 to detect the temperature of the glow plug G. The protective resistor 6 prevents an excessive current from flowing through the glow plug G when the main relay 2 is cut off, and therefore the temperature decreases from the upper limit value θ3 when the main relay 2 is cut off. When the temperature of the glow plug G reaches the lower limit value θ2, the processing circuit 1 activates the main relay 2.
conducts. In this way, the temperature of the glow plug G is maintained within the control temperature range θ2 to θ3.

Therefore, is the power consumed by battery 3? The quantity is large.

に信号を与える。By turning the switching element 7 on and off, the temperature of the glow plug G is controlled. The diesel engine is a so-called water-cooled engine that is cooled by a cooling liquid, and the temperature of this cooling liquid is detected by a temperature detection element 8 such as a thermistor. The glow plug G has a positive temperature coefficient, and the current decreases as the temperature increases. The temperature detection resistor 4 has a low resistance value of about 10+nΩ, and the voltage across the temperature detection resistor 4 is the line 9,
10 to a processing circuit 11. The voltage between the lines 9 and 10 when the transistor 7 is conductive has a value corresponding to the temperature of the glow plug G. Processing circuit 1
The temperature detection circuit 12 included in 1 is connected to lines 9 and 10.
The temperature of the glow plug G corresponding to the voltage between is detected, and when the detected temperature reaches the upper limit value θ13 of the control temperature range 012 to θ13 (described later), a signal is sent via line 13. and gives it to the 191 circuit 14. A trigger circuit 14 is provided in conjunction with the timer 15. timer 15
The 191 circuit 14 connects the temperature detection circuit 12 to the line 13.

The drive circuit 17 also receives a signal from the temperature detection circuit 12 via the line 18, and shuts off the transistor 7 when the temperature of the glow plug G exceeds the upper limit value θ131 of the control temperature range.

する。As shown in FIG. 3 (1), the temperature of the glow plug G exceeds the temperature θ11 at which fuel can be ignited, further exceeds the lower limit value θ12 of the control temperature range, and reaches the upper limit value θ13. As a result, the drive circuit 17 drives the transistor 7 as shown in FIG.
). The 191 circuit 14 activates the timer 15, and thereby the timer 15 starts clocking the time-open W corresponding to the detection output of the temperature detection element 8.

θ１３はたとえば９００°Ｃである。At the time when time W has elapsed after the transistor 7 was cut off, the temperature of the glow plug G has reached the lower limit value θ12. At this point, drive circuit 17 makes transistor 7 conductive. In this way, the glow plug G is heated again, and the glow plug G is maintained within the control temperature range θ12 to θ13. The lower limit value θ12 is, for example, 800'C, and the upper limit value θ13 is, for example, 900°C.

Therefore, when the Y range stuff is cut off, no current flows through the glow plug G at all, and no current flows through the glow plug G.
This embodiment does not consume power only for temperature detection as in the prior art described in connection with FIGS. . In addition, in this control system, the control temperature is the upper limit value θ13
and the lower limit θ12, and the inevitable hysteresis characteristic of the temperature of the glow plug G is obtained, so that stable and highly accurate temperature control can be performed.

Alternatively, in the case of an air-cooled diesel engine, the ambient temperature may be detected, or the temperature associated with the diesel engine may be detected.

Since the glow plug is energized with power after a certain period of time has elapsed, power is not consumed solely for detecting the temperature of the glow plug, and therefore, it is possible to reduce power consumption.
