The key points of modifying LNG cars are troublesome and detailed

If LNG is used in vehicles, it is mainly for vehicles with diesel engines. Because LNG itself is a cryogenic liquid with extremely high temperature requirements, the minimum capacity of LNG cylinders is more than 100 liters, so there is no trolley modified LNG at present. There are currently two ways to modify LNG vehicles, one is single-fuel and the other is dual-fuel.

Single fuel is to change the diesel engine of the vehicle itself to a gas engine, for its own gas refueling, or the vehicle is often at a low speed or stop and go vehicles, such as buses or dock low-speed vehicles, are suitable for changing to single fuel, of course, if the power of the engine itself is below 280 horsepower, you can also consider changing to single fuel. Another way is to change to diesel and natural gas mixed burning, this way itself does not change the working principle of the diesel engine itself, through the installation of a set of dual-fuel device to use the original car can use diesel and natural gas at the same time, more suitable for long-distance and power in more than 300 diesel engine vehicles.

Due to the fact that the maintenance work required for the characteristics of the gas engine itself is not sufficient, the modified gas engine will have more maintenance than the diesel engine, and the modification cost itself is also higher, but for the owner of the vehicle with sufficient gas supply, the 100% replacement rate is still very attractive.

Do you want to change to a truck or a racing car or a sedan.

Refit? This is almost outdated, you go to the lng car network to take a look, there is a lot of information to share for free.

Cars** can be modified LNG Each gas station has information on the manufacturer of modified natural gas.

The cost of converting the car to a single-fuel vehicle is 4,000-6,000 yuan, and the cost of a dual-fuel vehicle is about 2,000 yuan higher (excluding gas cylinders). The requirements for the vehicle are in good condition, and the vehicle with a running life of less than 3 years is not ideal for the vehicle that has been running for more than 4 years, and the exhaust treatment effect after modification is not ideal, which is of little significance. For the modification of diesel vehicles, it is recommended to purchase LNG vehicles directly.

Advantages of LNG vehicles For the comparison of calorific value per unit volume, 1 standard square of natural gas is equivalent to liters of diesel and equivalent to liters of gasoline.

After switching to an LNG vehicle, the SO2 in the exhaust can be reduced by more than 90%, CO can be reduced by 90%, HC can be reduced by 74%, NOX can be reduced by 39%, CO2 can be reduced by 24%, and noise can be reduced by 40%, which greatly reduces environmental pollution. Each tonne of diesel replaced reduces CO2 emissions by tonnes.

Low fuel cost: This is mainly reflected in the fuel **, LNG market sales ** higher than about yuan, 0 diesel ** yuan, 93 gasoline ** yuan, 97 gasoline ** yuan, the cost can save more than 40%.

The relative density of LNG is about about that, which is lighter than air, and it is easy to spread after leakage, and will not accumulate in low-lying places and catch fire; The ignition point is 650, which is much higher than the diesel ignition point of 260, and it is not easy to ignite; In addition, the cylinders used in LNG cars are high-pressure containers, and their manufacturing, inspection and testing have strict standards, and there are explosion-proof devices, so there will be no fire or ** due to collision.

Extend the service life of the engine and reduce maintenance costs: the LNG octane number is 130, the composition is stable, and it does not contain corrosive substances such as sulfide and moisture. LNG burns sufficiently, does not deposit carbon, has low noise, reduces the wear and tear of the engine, prolongs the life of the engine, and can save more than 50% of the maintenance cost.
