What are the categories of Ranqi cars, and the advantages of Ranqi cars?

1. Gas cars, also known as natural gas cars, are mainly divided into liquefied petroleum gas cars and compressed natural gas cars.Gas cars are mainly fueled by natural gas. Its CO emissions are reduced by more than 90% compared with gasoline cars, hydrocarbon emissions are reduced by more than 70%, and nitrogen oxide emissions are reduced by more than 35%. It is a relatively practical low-emission car.

2. Liquefied natural gas (LNG) has high ignition point and strong safety performance, which is suitable for long-distance transportation and storage.

3. The environmental protection performance, renewable raw materials, high efficiency, safety performance and other advantages of natural gas vehicles have received wide attention. Although its use and construction require certain technical and economic cost support, it is a more superior choice in terms of environmental protection and energy saving.

4. LNG bus - LNG (liquefied natural gas) can compress the volume of natural gas to a greater extent. Once inflated, it can drive 500km or even more than 1000km, which is very suitable for long-distance transportation, and LNG is liquid and is not affected by the natural gas pipeline network. At the same time, all indicators are significantly better than LPG.

5. Compared with fuel vehicles of the same power, HC (hydrocarbons) in the exhaust gas of natural gas vehicles can be reduced by 90%, CO can be reduced by 80%, and NOX can be reduced by 40%; natural gas has significant advantages in reducing greenhouse gas emissions. Foreign research results show that the CO2 emissions of natural gas vehicles can be reduced by more than 20% compared with traditional vehicles.

However, the car's air intake pipe can't run! Ask the master for an answer!

1. It generally occurs when the engine is at medium and high speed.The exhaust pipe is fired, and it gets better or disappears after refueling. This is because the spark energy is not enough to ignite the dilute mixture, and it is discharged into the exhaust pipe and burns. In general, as long as the oil road injector is dredged and the amount of fuel injection is adjusted, the fault will disappear.

2. The main reason for the decline in power of natural gas vehicles is the characteristics of the fuel itself and the structure of the engine. In terms of fuel properties, gasoline is a liquid fuel, while natural gas is a gas fuel.

3. After the engine valve, cylinder liner, piston and ring are worn, the cylinder pressure does not meet the requirements. The gap between the intake valve is too large and the gap between the exhaust valve is too small. Or the intake and exhaust door is snapped. It will lead to lack of cylinder. Affect the acceleration performance. The timing belt (chain) is worn, resulting in the ignition time, which also affects the acceleration performance.

4. The reasons for the acceleration of the car are: failure of the ignition system, improper adjustment of the valve gap, perforation of the exhaust pipe, and blockage of the ternary catalyst. The ignition system fails. If the spark plug is aging or fails, stepping on the accelerator deeply may make the fuel unable to ignite, resulting in a missing cylinder, and the exhaust pipe is prone to the sound of gunfire.

What are the brands of natural gas vehicles

1. BYD, Beijing Hyundai, Chang'an, Dongfeng Citroen, Shanghai Santana, FAW Weizhi, FAW Volkswagen, etc. The natural gas vehicle freight series include Dongfeng, FAW Jiefang, Shaanxi SINOTRUK, etc. Gas vehicles, also known as natural gas vehicles, are mainly divided into liquefied petroleum gas vehicles and compressed natural gas vehicles. Gas cars are mainly fueled by natural gas.

2. Models using natural gas are new energy models. For example, Hyundai, BYD, Chang'an, FAW-Volkswagen, etc. have all launched natural gas models; compared with traditional fuel vehicles, natural gas models have less impact on the environment and less exhaust emissions; natural gas vehicles are powered by natural gas.

3. BYD, Beijing Hyundai, Chang'an, Dongfeng Citroen, Shanghai Santana, FAW Weizhi, FAW Volkswagen, etc.The natural gas vehicle freight series include Dongfeng, FAW Jiefang and Shaanxi SINOTRUK. Natural gas vehicles are cars powered by natural gas as fuel.
