Abstract

The invention relates to an intelligent control system for fuel oil heating. The intelligent control system comprises an engine, an engine controller, a main oil tank, an auxiliary oil tank, a fuel oil heating controller and a storage battery. The main oil tank is communicated with the engine through a main oil tank switch valve, the auxiliary oil tank is communicated with the engine through an auxiliary oil tank switch valve, the engine controller is in signal connection with the fuel oil heating controller, and the fuel oil heating controller is electrically connected with an ignition switch, the main and auxiliary oil tank switch valves, a relay coil, a fuel oil heating switch and a temperature controlled switch; the positive pole of the storage battery is grounded through a battery main switch, a relay contact and a main oil tank heater in sequence, and the negative pole of the storage battery is grounded; when the temperature of an oil sucking opening of the main oil tank is lower than 5 DEG C, an oil way is switched to an auxiliary oil tank loop so as to start the engine, when the rotating speed of the engine reaches 700 rpm, the main oil tank heater starts to heat, when the temperature of the oil sucking opening of the main oil tank reaches 25 DEG C, heating is stopped, and the oil way is switched to a main oil tank loop. By means of the intelligent control system, the starting performance of the engine is improved, and the safety and the reliability are high.

Description

technical field [0001] The invention relates to the field of automobile electrical systems, in particular to an intelligent fuel heating control system and a control method thereof, which are mainly suitable for avoiding the problem of battery feeding caused by excessive heating power during static heating, thereby improving the starting performance of the engine. Background technique [0002] As the outside temperature decreases, the viscosity and density of diesel oil both increase. Increased viscosity and increased density of diesel oil lead to poor fluidity, which affects the starting of the diesel engine and the normal operation of the engine. To ensure the normal starting of the engine, it is necessary to use low-grade diesel oil. For normal cars, when the ambient temperature is 6 degrees lower than the diesel label, it will affect the normal start of the engine. Therefore, it is recommended to use 0﹟ diesel oil when the temperature is above 4°C; -10﹟ diesel oil when...
