Car burning natural gas has no effect on the car,,
Three point oneThe decrease of inflation coefficient is an important reason for the decline of the power of natural gas vehicle. However, the decline in the coefficient of gas is determined by the nature of the gas itself, from the fuel is clearly unable to solve this problem, the only solution is to take the intake boost measures. However, the increase in air intake will undoubtedly increase the size and quality of the engine, there are some difficulties in the implementation.
When the vehicle is made of natural gas, it is found that the combustion chamber is obviously corroded, and even the crankshaft is corroded. The valve, piston ring and cylinder are seriously wornThis is another problem faced by natural gas vehicles. The reason for the corrosion and early wear of natural gas vehicles is that there are trace sulfur compounds in natural gas
In terms of fuel properties, gasoline is a liquid fuel, while natural gas is a gas fuel. The use of gasoline, and the volume of the air intake volume of liquid gasoline compared to almost negligible, but the use of natural gas as fuel, fuel volume occupies a large proportion in the whole intake, resulting in the amount of air entering the cylinder is reduced, air coefficient decreased, resulting in reduction of engine power.In the engine structure, the main factor to determine engine power is the compression ratio of the engine, the greater the compression ratio, the higher the thermal efficiency, the greater the effective power. At the same time, the greater the compression ratio, the greater the tendency of engine detonation. Therefore, the engine compression ratio must also be consistent with the fuel antiknock. Gasoline antiknock determines the compression ratio of gasoline engine can not be too large, but the natural gas antiknock good, can be used to compress the larger engine, thereby enhancing its power. The application of natural gas vehicles is still in its infancy, the supply of natural gas is not as popular as gasoline, in this case, it is difficult to promote the design of natural gas engine cars. At present, most of the natural gas vehicles put into operation are dual purpose fuel vehicles. In order to take into account the use of gasoline, the dual fuel vehicle has a smaller or no increase in compression ratio. As a result, the characteristics of high anti explosion of natural gas have not been fully utilized, which results in the decrease of engine power.
OneOne of the main problems in the use of natural gas vehicles is that the power of the engine is significantly lower than that of gasoline. According to reports, the car in the use of natural gas as fuel, power generally declinedThe main reason for the decline of the power of natural gas vehicles is the characteristics of the fuel and the structure of the engine.
Because of the obvious advantages of natural gas vehicles in emissions, compared with the use of gasoline vehicles, natural gas vehicle emissions of particulate matter is almost zero,
