Will Fuel Vehicles Be Phased Out?
1 Answers
The claim that fuel vehicles will be phased out by 2025 actually originated from a meeting of the Ministry of Industry and Information Technology. The average lifespan of fuel vehicles is between 10 to 15 years. Considering unrestricted usage would be within 10 years, even the last batch of fuel vehicles, based on average lifespan, would persist until 2035. During this period, they can still be used and will not be phased out. Introduction: The energy density of gaseous fuels is low. Natural gas vehicles carry less fuel, resulting in shorter driving distances compared to gasoline vehicles. Gaseous fuels occupy a certain volume in the combustible mixture within the cylinder (the volume occupied by liquid fuel in gasoline engine cylinders is negligible). Under the same cylinder working volume, less work is done when using natural gas as fuel. Conversion from Original Gasoline Engines: Most natural gas engines currently in use are converted from original gasoline engines. Therefore, when gasoline vehicles switch to natural gas, their power often decreases by about 10%-20%, leading to phenomena such as reduced climbing power and slower acceleration response, as reported by drivers. If diesel vehicles are converted to use natural gas in a "dual-fuel" mode, such phenomena do not occur, but the structure of the conversion components is more complex. Fuel System: Since current natural gas vehicles are modified based on original gasoline or diesel vehicles, most of the original gasoline or diesel fuel systems are retained. The addition of a natural gas fuel system, especially the gas tank, reduces the effective space of the original vehicle and also increases its own weight.
