Question 2: What do you mean by engine country, two countries and three countries? Hello, this refers to the national motor vehicle exhaust emission standard, country 2, which is the national motor vehicle exhaust emission standard No.2; Country three, that is, the third standard .. Now most cities are country four standards, and Beijing and Shanghai are country five. ..
Question 3: What does motorcycle country mean by one country, two countries and three? China 1, China 2 and China 3 refer to the emission standards of exhaust gas, that is, the content of harmful gases in exhaust gas is different, which has nothing to do with the quality and performance of vehicles. However, with the increasingly strict requirements of national environmental protection laws and regulations, all motor vehicles, including motorcycles, must implement increasingly strict ring valve standards, otherwise production is not allowed.
Compared with the first country, the second country mainly meets the standards by adding a secondary air intake system. Compared with the second country, the third country added a conversion catalyst made of precious metals in the exhaust pipe to purify the harmful gases in the exhaust gas, and further controlled the oil quantity by finely controlling the carburetor, and added a carbon canister to absorb the evaporated oil and gas in the oil tank to meet more stringent environmental protection requirements. Some national three models have also adopted EFI technology to reduce emissions, and motorcycles will inevitably implement national four standards in the future. By then, carburetor will be completely eliminated, and all motorcycles will adopt EFI.
During the period of upgrading from National 1 to National 2 and National 3, the performance of motorcycles has basically not changed, and may even decline slightly. However, due to the increase in manufacturing costs, prices have been rising all the way. Because motorcycles with substandard exhaust gas are not allowed to be produced, it seems that they are not directly related to the owner, so they must pay more for a car, even if the motorcycle owner pays for environmental protection.
