What is the difference between the national second car and the national third car?

The difference between the national third engine and the national second engine is the content of harmful substances emitted by the engine exhaust gas. The national third engine is lower than the national second engine. Distinguishing the difference between the engine from the structure of the engine, the fuel supply system of the national third engine and the national second engine are different, and the emission of harmful substances in the engine exhaust is also different.

Look at the engine. The second country is the most common and simplest engine. The engine adopts a naturally inhalation method, which is very rough. When igning, the engine noise is louder than that of the third country, and there is more black smoke.

In addition, the price of the national third car is also higher than that of the national second car. Because the national third car is more advanced in technology and environmental protection, the production cost is also higher, resulting in higher prices. However, considering the performance and environmental protection of the national third car, this price difference is also acceptable.

The oil supply system of No. 3 and No. 2 is different, and the emission of harmful substances in the engine exhaust is also different. The internal structure of the No. 3 engine is improved on the basis of the No. 2 engine, and the cost of the No. 3 engine is much higher than that of the No. 2 engine. From July 1, 2008, new cars are only allowed to cars with national three emission standards.

The three countries and four countries are divided according to different years, and the five countries have different requirements. Among them, the first country requires the limit of vehicle emission pollutants and experimental methods, as well as signs and on-board diagnostic systems. The national second standard mainly targets the emission limits of carbon monoxide and hydroxide, which has higher requirements than the national first standard.

How about the quality of the national third engine?

The national third engine is more reliable, which can better ensure the safety of the car and reduce the possibility of various accidents, so as to ensure the safety of car users.

Good. Source manufacturer. Absolutely no renovation, reliable quality, diverse styles, quality assurance. Run smoothly. Focus on quality, no oil burning, non-destructive installation, high-speed, high-precision, low-noise, more durable, ingenuity to create energy-saving and efficient.

The country is good. Compared with the second engine, the national third engine has higher power and lower fuel consumption. This is because the national third engine adopts more advanced combustion technology, which makes the engine more thermally efficient and can generate greater power with less fuel consumption.

Good.Source manufacturer. Absolutely no renovation, reliable quality, diverse styles, quality assurance. Run smoothly. Focus on quality, no oil burning, non-destructive installation, high-speed, high-precision, low-noise, more durable, ingenuity to create energy-saving and efficient.

The national third engine has good insulation performance, which can more effectively prevent overload, so as to reduce electromagnetic interference, effectively protect the circuit and electronic equipment of the car, and thus extend the service life of the car.

An all-fuel engine is an engine that uses diesel as fuel. In fact, as a diesel engine with a small cylinder diameter, the full fuel capacity is relatively large, and the overall quality is about the same.

Good quality. High reliability: The all-fire engine has been rigorously designed and tested, and adopts advanced technology and high-quality parts to ensure excellent performance under various working conditions.

Not bad. According to the relevant information in Baidu, the diesel engine of Guosanda is relatively powerful, with low fuel consumption, more fuel-efficient, and emits less exhaust pollutants, which is relatively more energy-saving and environmentally friendly, so it is not bad.

The all-fuel engine has the characteristics of strong power, low fuel consumption and high reliability, which is related to the continuous pursuit of intelligent strategy of all-fuel. It uses a professional tool chain, from the perspective of data collection, analysis, processing and optimization, and cooperates with certain methodological guidance to improve the quality of the development process and ensure the steady and efficient performance development of new products.
