Why are Small Cars Rarely Modified With LNG?

CNG vehicles refer to vehicles that use compressed natural gas instead of conventional gasoline or diesel as vehicle fuel. LNG vehicles comply with the most stringent vehicle emission regulations in the world. It refers to a car that uses liquid natural gas at a temperature of -162 degrees under normal pressure and is stored in a vehicle-mounted insulated gas cylinder as a power fuel.

The main component of LNG is methane, which is recognized as the cleanest fossil energy source on earth. However, as the temperature of the LNG storage tank will rise with the storage time, the liquid will turn into gas, and the internal pressure of the cylinder will be automatically discharged after it exceeds a safe value to ensure a safe pressure.

Moreover, the density of natural gas is lower than that of air, and the emitted gas will escape upwards. The small amount of gas leaked when a large car is parked outdoors quickly dissipates in the air, but if it is a small car, there is a high chance to park in a confined space such as a garage. The released natural gas accumulates in the confined space, which may cause the accumulation of gas.

In addition, the LNG bottle is a double-layer stainless steel bottle with a large weight and a series of additional devices such as gasification and pressurization. It is really inappropriate to install on a small car. More suitable for continuous operation buses and large trucks.

Operating vehicles such as taxis and buses are more likely to be converted into compressed natural gas-powered cars. In addition to natural gas in oil fields and natural gas fields, CNG can also use artificial biogas. The finalized gasoline car is refitted, and a special compressed natural gas device is added while retaining the original car's fuel supply system to form a CNG dual-fuel car. The fuel conversion only requires a toggle switch. It can travel about 200 kilometers with one refill of natural gas.

Therefore, CNG is currently used for taxis or small buses. LNG is used for large vehicles such as large buses, large trucks, heavy trucks or ships.
