Description
Technical Field
The invention relates to the technical field of fuel supply system devices of gasoline octane number measuring machines, in particular to a fuel supply system device of a gasoline octane number measuring machine suitable for a plateau environment.
Background
A gasoline octane tester was used to test the octane number of the fuel. In conventional gasoline engines and other spark-ignition engines, octane number is an important indicator for evaluating the knocking resistance of fuels. The traditional gasoline octane number tester adopts a carburetor oil supply system to supply oil. The level of atmospheric pressure in the environment can affect the oil supply function of the system. If the condition for testing the fuel octane number by the gasoline octane number tester is that the fuel octane number can be normally tested in an atmospheric pressure environment, namely, in an area with the altitude lower than about 1500 meters. However, if the carburetor fuel supply system of the conventional gasoline octane number meter is insufficient in fuel supply and the atomization quality of the fuel is too low due to low atmospheric pressure in a plateau environment (an area with an altitude higher than about 1500 m), that is, in an environment lower than one atmosphere, the gasoline octane number meter cannot accurately measure the octane number of the fuel. In addition, the fuel octane rating measuring machine adopts a carburetor oil supply system which is different from the current oil supply system of the gasoline engine, and the obtained fuel octane rating result may not be capable of representing the actual condition of the fuel in the gasoline engine. Therefore, the carburetor oil supply system is required to be modified into an electric control oil injection supply system, so that the gasoline octane number tester can normally conduct the test of the fuel octane number under different atmospheric pressure environments. However, if a small fuel pump is used to provide the fuel supply pressure in the fuel supply system, the problems of insufficient fuel supply pressure and unstable fuel supply pressure in the fuel line are liable to occur during a long-term test. The atomization quality of the fuel in the air inlet channel can be affected, so that the octane number of the fuel cannot be accurately measured, and in addition, the small fuel pump can generate certain heat during operation, so that the temperature of the fuel in different oil ways in the system is different, and the measurement error of the octane number can be affected. If the fuel pump is frequently replaced or the cooling circulation device is adopted to cool the fuel temperature of each path, the problems of difficulty in installation and disassembly and certain cost are caused.
In view of the above, there is no suitable solution to accurately measure fuel octane number in plateau areas. Therefore, how to innovatively design a fuel supply system device of a gasoline octane number tester to enable the gasoline octane number tester to accurately measure the octane number of fuel under different atmospheric pressure environments is a technical problem to be solved in the art.

Further, the first linear relationship is p1=kp2, where P1 is a pressure value of the gas path between the high-pressure gas cylinder and the gas control switch monitored by the first pressure gauge, P2 is a pressure value of the fuel oil path between the fuel tank and the fuel rail monitored by the second pressure gauge, and K is a pressure fluctuation coefficient; and when the monitored value in the second pressure gauge does not reach the required value, adjusting the pressure value of the first pressure gauge, so that the pressure value of the first pressure gauge and the pressure value of the second pressure gauge accord with the first linear relation.
Further, the pressure fluctuation coefficient is determined in the following manner: the method comprises the steps of obtaining a volume parameter A1 of the fuel tank, a pipe diameter parameter A2 of the fuel pipe and a length A3 of the fuel pipe between the top surface of the fuel tank and the top end of the second pressure gauge, wherein K=A1×A2×A3.
Further, the fuel supply system device has a plurality of oil passages, each including a gas control switch, a fuel tank, and a second pressure gauge; according to the index of the required measured fuel, the oil ways are adjusted, and only one oil way is opened at a time.
Further, the oil supply pressure of the high-pressure gas cylinder is more than 10 atmospheres, and the fuel pressure in the oil path is kept at 4-5 atmospheres.

The electronic control unit is adopted to control the oil injection quantity of the oil injection nozzle 4, so that the oil injection quantity when the engine reaches the maximum knocking can be accurately found. The fuel injection nozzle 4 is mounted on an intake pipe located short of an intake valve of the engine. The air inlet pipeline of the engine is communicated with the arranged fuel system. The fuel injected from the fuel injector 4 is sufficiently atomized in the intake pipe of the gasoline octane number tester and sufficiently mixed with air before entering the combustion chamber of the engine.
In the process of measuring the octane number of the fuel, toluene reference fuel, high standard sample fuel, low standard sample fuel and fuel to be measured are respectively stored in a high-pressure-resistant fuel tank.

The high-pressure gas cylinder is connected to the high-pressure resistant fuel tank through a high-pressure pipe, the gas is controlled to be conveyed by the gas control switch, and the oil in the fuel tank is controlled to enter the oil nozzle by the oil path conveying control switch. The high pressure resistant fuel tanks are connected to respective second pressure gauges by using fuel pipes. A pressure gauge, a pressure regulating valve and a pressure relief valve are arranged in the fuel tank. The second pressure gauge is connected to the oil rail and the oil nozzle in sequence through the oil pipe. The second pressure gauge is arranged in the oil way, so that whether the pressure in the oil way system reaches the set pressure value or not and whether the fuel oil system can normally work for a long time or not can be monitored conveniently.
The position of the oil nozzle is selected on the air inlet pipe at a position which is not far away from the air inlet valve, and the oil nozzle has larger oil injection pressure, so that the fuel oil can be fully atomized in the pipe and fully mixed with the air. The injection pressure is almost the same as the injection pressure of an actual engine, and the combustion condition of fuel in the actual gasoline engine can be fully represented. By adopting the electric control oil nozzle, the mixing ratio of fuel oil and air when the knocking intensity generated by the engine reaches the maximum value can be accurately found.
