Fuel temperature control device for injection engine

The fuel temperature control device of the present injection engine is improved for the fuel combustion efficiency of the fuel injection engine, and the technology of generating the cooling surface and the heating surface on the wafer under the wafer by using the input current of the cooling chip simultaneously starts the vehicle. In the initial stage, the fuel is heated by the heating surface of the cooling chip, so that the fuel is more easily atomized when it enters the injector and accelerates the combustion chamber to reach the working temperature quickly, and at the same time, the combustion which is easy to occur when the engine is low-temperature combustion is incompletely reduced. The condition, when the engine reaches the working temperature, the cooling surface of the cooling chip begins to cool the fuel, so that the temperature of the combustion chamber is lowered when the cooled fuel enters the combustion chamber, thereby preventing the combustion temperature from being too high and causing death. Nitrogen oxide exhaust gas is discharged into the atmosphere, and at the same time, the temperature of the mixture entering the combustion chamber can be lowered to increase the oxygen content, improve the explosion condition during combustion, and increase the engine output horsepower. In addition, the temperature control unit transmits the temperature sensor to detect Measuring the engine temperature ensures that the heat of the cooled wafer is generated when the engine is colder than the minimum operating temperature of the engine. Start working to achieve the effect of preheating the engine; and when the temperature of the engine body reaches above the normal operating temperature of the engine, the cooling surface of the cooling chip starts to operate, thereby promoting the complete combustion of the engine and improving the output force, Ensure that engine performance continues to maintain optimal working conditions. The water-cooled heat sink of the present invention can dissipate the waste energy generated by the cooled wafer by water cooling to the system to improve the performance of the system for heating or cooling the fuel.

The fuel engine is the most used vehicle for current power vehicles. According to the statistics of the Ministry of Communications, the number of small passenger cars in Taiwan has exceeded 6 million, and the number of locomotives has exceeded 15 million. Therefore, the consumption of steam locomotives has become increasingly serious. According to the statistics, the current available gasoline stock can only be used for about 38 years, and the exhaust gas pollution generated by the fuel engine has caused the main cause of the global warming of the earth. Therefore, it is imperative to improve the combustion efficiency of the fuel engine. The general vehicle engine combustion efficiency improvement device or method is as follows:

1. Heating type fuel-saving device: The fuel-saving device of the new patents M347468 and M364124 of the Republic of China mainly uses the electric energy or the heating method of the engine itself to heat the fuel inlet pipe of the fuel system to enhance the kinetic energy of the fuel molecules entering the combustion chamber. The atomization effect, but the heating method causes the temperature of the mixture entering the engine room to be too high, so that the energy generated after the combustion explosion generates more nitrogen oxides and carbon monoxide, thus causing invisible air pollution.

2. Improved auxiliary device for improving engine fuel combustion efficiency: The improved device of the Republic of China new patent M424257 is a method for generating hydrogen and oxygen by electrolysis of water against high-voltage electricity, and sending hydrogen and oxygen generated after electrolysis The fuel pipe is mixed with the fuel, so that the mixed gas enters the combustion chamber to improve the combustion efficiency. However, this method requires input of a high-voltage current for the electrolysis behavior to be dangerous, and the generated hydrogen and oxygen are highly flammable gases. If there is a leak in the middle, it is easy to cause an explosion hazard.

3. Structure of cold air chilled petrol: The structure of the new patent of the Republic of China, M379527, is used to recover the low temperature effect of the cold air low pressure refrigerant pipe in the engine room, so that the temperature of the fuel entering the combustion chamber is lowered to keep the combustion chamber free of carbon. Trouble, but this method needs to have cooling function when starting cold weather, and the low temperature effect produced by the refrigerant pipe is not stable system, so it can not provide accurate cooling timing, and it is easy to cause chaotic fuel burning conditions.

4. Accelerated fuel-saving devices: The new patents M405477, M383043 and M389775 of the Republic of China use magnetic materials to magnetize the fuel pipe to improve the molecular structure of the fuel itself. However, the magnetized fuel molecules have weak magnetic properties. It is impossible to magnetize all molecules completely, and the fuel flow rate may not be able to pass the magnetic material magnetization in a short time.

According to the above statement, the devices that provide the engine combustion efficiency improvement have the problems of excessive volume or complicated structure. Therefore, this design provides a control method of the engine fuel temperature through another design method, so as to improve the combustion efficiency and easily For the purpose of erection or use.

The purpose of this creation is to control the heating or cooling of the fuel temperature of the vehicle to improve the combustion environment when the fuel enters the combustion chamber, thereby improving the combustion efficiency and reducing the emission of toxic exhaust gas. The creation includes a cryogenic wafer and oil. Cold head, pressurized pump water cooling head, heat exchange water tank, electronic fan and temperature control unit, etc., use the cryogenic wafer as the power source for temperature control of the fuel, and the heat exchange surface of one side of the cooling chip is closely related to the oil cooling head. Engaging, and the other side of the cooling chip is in close contact with the heat exchange surface of the water pump head of the pressure pump, and the temperature of the engine body is detected by the temperature control unit to determine the current direction of the input cooling chip, and is pressurized by the fuel pump. The fuel passes through the fuel pipe first through the oil cooling head, and the temperature of the fuel is changed by exchanging the heat exchange surface of the oil cooling head with the electric heating chip, and then the fuel having changed the temperature is sent to the pressure generated by the fuel pump to the fuel. The atomization effect is generated in the injector and sent to the combustion chamber of the engine for combustion; however, the waste energy generated on the other side of the refrigerant wafer is thermally conducted. Passing to the heat exchange surface of the water pump of the pressure pump, the waste liquid in the water cooling head of the pressure pump absorbs the waste energy and is sent to the heat exchange water tank through the internal pressure pump, so that the waste energy can be generated by the electronic fan. The air flow is discharged to the external environment for the energy exchange behavior of the heat exchange water tank, and the coolant after the energy discharge flows back to the pressure pump to repeat the heat in the water cooling head. Exchange actions.

According to the above components, the fuel temperature control can be performed according to the two different conditions of the engine just starting up and the normal working temperature of the engine: when the engine is just started, the temperature of the engine body is detected by the temperature sensor of the temperature control unit. The signal is transmitted to the temperature control unit, and the temperature control unit activates the cooling chip to generate a heating effect on the side of the cold wafer contacting the heat exchange surface of the oil cooling head, thereby heating the fuel to accelerate the fuel atomization effect and reduce the engine heat engine. At the same time, the cooling effect generated by the other side of the cooling chip is exchanged by the water pump of the pressure pump to remove the waste energy away from the system; when the temperature sensor of the temperature control unit detects that the engine body has reached the working temperature When the signal is transmitted to the temperature control unit to start the cooling wafer, the surface of the cooled wafer contacting the oil-cooling head exchange surface generates a cooling effect to lower the fuel temperature, so that the atomization effect generated by the injector can be achieved. Reduce the operating temperature of the combustion chamber, and reduce the temperature of the mixture according to the principle of thermal expansion and contraction, thus improving the mixing into the engine room. Oxygen-containing density, in order to achieve lower emissions and improve horsepower, while the effect of heat generated by the actuation of the pressurizing pump through a water-cooled head exchange energy is discharged the other side of the refrigeration system of the present wafer.

Connect the fuel outlet pipe (104) to the oil outlet of the oil cooling head (102) and fix it with the pipe clamp (122), and connect the other end of the fuel oil pipe (104) to the fuel injection nozzle (105); the first coolant One end of the tube (110) is connected to the water outlet of the pressure pump water cooling head (106) and the other end is connected to the water inlet of the heat exchange water tank (112) and fixed by the pipe clamp (122), and the second coolant pipe (111) One end is connected to the water inlet of the pressure pump water cooling head (106) and the other end is connected to the water outlet of the heat exchange water tank (112) and fixed by the pipe clamp (122), and the electronic fan (113) is connected to the heat exchange water tank.
