With the increasingly strict environmental protection policy, the emission standards for motor vehicles are also constantly improving, in the past few years, the "national six" policy has caused a lot of commotion, in addition to the policy phased implementation, the impact on the owner of the car is also there, some cars have particle recovery failures, etc., even when driving the vehicle, will feel that the power of the vehicle is not as good as the car before the national five, so is this really the case?
Speaking of this, we have to analyze from the technical level of the engine of the national six and national five models, the national five and the national six still have a big gap in the engine technology, first of all, the vehicle emission system has a clear difference, according to the national six emission standards of light gasoline vehicles carbon monoxide, hydrocarbons, non-methane total hydrocarbons and nitrogen oxide emissions will be reduced by about 50% than the national five stage, particulate matter emissions reduced by about 40%, and so at the same time a car wants to meet the national six standards The core lies in the upgrade of the exhaust gas purification system. The most important of these is the accuracy of the three-way catalytic converter and fuel system.
To simply understand this, is to limit the output power of the part to meet the conversion efficiency of the vehicle's ternary catalyst, which requires the electronic control unit control standard between the engines to be more accurate, after all, the atomization requirements for gasoline are higher, this is like, the engine of the fifth country is burning to a bottle of water to achieve the power output requirements, and the standard of the sixth country is good in a bottle of water as long as the general amount to meet, the amount is less, the natural force is less, but we will not be affected too much in our daily driving.
In general, driving the car of China 5 and China 6, there are generally some differences in the power, the slight gap, generally for people with low power requirements, there is almost no gap in such a power experience, in the national six stage, many automobile companies are quite insufficient, of course, some car companies for the national six standards to develop models, which also caused us to feel different power when using the vehicle.
