Description

Electric and water heating device for engine oil and fuel tank diesel

technical field

The utility model provides a heating device in the field of thermal engineering, in particular a device for heating engine oil and fuel tank diesel with electricity and water.

Background technique

Existing diesel oil tanks use high-grade oil as fuel in cold seasons in winter, so as to avoid the diesel engine from not being able to normally supply oil due to the low temperature causing the diesel to solidify and not flow easily. Use low-grade oil in summer and warm seasons to reduce fuel costs. If low-grade oil can also be used in winter and cold seasons, the cost of fuel can be reduced. However, due to the low freezing point of low-grade oil, when the temperature drops to a low enough level, it will become viscous, even semi-solid, and cannot enter the engine through the oil pipe, thus causing the engine to stop and cannot run. In order to be able to use low-grade oil even when the temperature is low, it is necessary to heat the fuel in the tank. Common heating methods include electric heating, engine cooling water heating and exhaust gas heating.

Among them, electric heating requires battery power, consumes a lot of useful work of the engine, wastes fuel, and is prone to leakage, and even causes fire or explosion accidents. Therefore, it is less used.

Among them, there are also many ways to heat the engine cooling water, usually consisting of a combination of a low fuel tank and a high fuel tank. Most of its low fuel tank heaters are coil type, which takes up a lot of space, has a small heat exchange area, and has no temperature control device, which can easily cause the oil temperature to be too high or too low, resulting in clogging of the oil pipe, causing the engine to cease fire, and causing the engine to overheat or Insufficient output due to low fuel density. After starting the engine with high-grade oil and running it, it takes quite a long time for the engine coolant to reach the temperature that can heat the diesel oil, which is used to heat the diesel in the low-grade oil tank. After switching from high-grade oil to low-grade oil , Low-grade oil cannot quickly increase the oil temperature and work normally, so it is easy to cause poor oil supply of low-grade oil and affect the normal operation of the engine.

Among them, diesel oil can also be used when the engine exhaust is interspersed through the fuel tank, but the temperature is difficult to control and the safety is poor, so it is less used in manufacturing.

In a cold state, the oil in the engine is also easy to freeze, affecting the oil supply, resulting in incomplete gasification of fuel and insufficient combustion. Especially due to insufficient supply of engine oil, it is easy to cause excessive wear of engine pistons and cylinder blocks, which affects the service life of the engine.

Contents of the invention

In order to overcome the disadvantages that the existing engine oil and diesel oil in the fuel tank cannot be operated normally due to the influence of cold temperature, the utility model provides a device for heating engine oil and diesel oil in the fuel tank by electricity and water. The device solves the problem of vehicle engine start-up and the use of low-grade diesel oil by installing an electric heater in the engine oil tank, a cooling water heater in the low-grade diesel oil tank, and an electric heating wire in the low-grade oil suction pipe. question.

The scheme that the utility model solves technical problem adopts is:

1. Install an oil heater in the oil tank at the position of the oil discharge nozzle of the engine bottom case;

2. A cooling water heater is installed at the bottom of the low oil tank, and an electric heating wire of the low oil suction pipe is connected to the low oil suction pipe;

3. There is a switching valve connected to the high-grade oil suction pipe and the low-grade oil suction pipe, and connected to the oil supply pipe;

4. A temperature controller is installed in the cab, which is connected with the temperature sensor, electric heater and electric heating wire through wires to display and control the heating temperature.

Positive effect is: because the electric heater of engine oil is installed in the engine oil tank of the engine oil discharge mouth of engine sump, engine oil can be preheated, reaches the effect of safe quick start. Because the cooling water heater of flat shape is installed in the low-number oil tank, the engine cooling water can be used to heat the low-number diesel oil, so that it can be used normally at low temperature. Since the electric heating wire is connected in the low-grade oil suction pipe, the temperature of the diesel oil sucked into the engine can be quickly increased when the low-grade oil is initially used, so that it can be operated quickly with low-grade diesel oil. Because the temperature controller is installed in the cab, it can display and control the temperature of the engine oil temperature and the diesel oil in the low-grade fuel tank, so as to ensure normal use and operation. It can achieve the effect of quick start of the engine in cold season and running with low-number diesel oil. The utility model is suitable for use on diesel engines and diesel automobiles.
