Abstract

The invention relates to an automatic control device for heating an oil tank by using automobile exhaust and an automatic control method based on the same. Through the device and the method, the problem of the existing device for heating a diesel vehicle oil tank can not achieve automatic control of a heating process is solved. The automatic control device comprises an electric control valve, a central processing unit (CPU), a temperature sensor, a light-emitting diode (LED) indicating lamp, a buzzer and a display screen. The automatic control method based on the device includes that the oil tank temperature is detected and displayed; whether the oil tank temperature is larger than or equal to a heating upper limit preset value is judged, on yes judgment, the LED indicating lamp is red, the buzzer alarms, and heating is stopped; whether the oil tank temperature is smaller than or equal to a heating lower limit preset value is judged, on yes judgment, the LED lamp is yellow, and heating is started; and otherwise the LED indicating lamp is green. The automatic control device and the automatic control method are applied to automatic control and heating of the automobile oil tank, especially high-latitude areas and south-north transportation truck groups.

Description

technical field [0001] The invention relates to an automatic control device for heating a fuel tank by using automobile exhaust gas, and an automatic control method based on the device. Background technique [0002] In winter, the temperature drops rapidly. When the diesel temperature is close to or lower than the freezing point temperature corresponding to the diesel grade, the diesel will produce waxing, solidification and other phenomena, thus reducing the fluidity of diesel and affecting the starting and normal operation of diesel vehicles. During operation, the viscosity increases, which affects the atomization effect of diesel and increases fuel consumption. Especially in alpine regions, diesel vehicles may not even work when the situation is severe. Therefore, when winter comes, we can't help but pay attention to the problem of diesel freezing. [0003] In order to prevent diesel oil from waxing at low temperature, the following methods are generally adopted: [00...
