Does Converting to Natural Gas Affect the Engine?

[DeValentina]

Due to the low energy density of gaseous fuels, natural gas vehicles carry less fuel than gasoline vehicles, resulting in shorter driving ranges. Most natural gas engines currently in use are converted from gasoline engines, so after converting to natural gas, the power of the vehicle often decreases by about 10% to 20%. Since natural gas vehicles are modified based on existing gasoline or diesel vehicles, most retain the original fuel system of the gasoline or diesel engine. Therefore, it is necessary to install a natural gas fuel system in the trunk of the original vehicle, especially the gas cylinder, which reduces the effective usable space and increases the vehicle's weight. Currently, most natural gas engines on the market are converted from gasoline engines, so after "converting to natural gas," the vehicle's power typically decreases by about 10% to 20%. Additionally, as a gaseous fuel, natural gas is extremely difficult to store and transport. It can easily cause sudden and severe knocking in the cylinders, leading to poor engine break-in and subsequent insufficient vehicle power. After converting to natural gas, it is necessary to periodically use gasoline for a certain period. If gasoline is not used for a long time, the consequence is that the fuel lines do not receive the lubrication from gasoline, leading to aging and cracking of the fuel lines, which can cause the vehicle to self-ignite while driving.
