Can Removing GPF from China 6 Vehicles Improve Performance?

[DeAdam]

Removing GPF from China 6 vehicles does not necessarily improve performance. Here is more information about emission standards: 1. China 4 Emission Standard: This is the national fourth-phase motor vehicle pollutant emission standard. The main pollutants emitted by vehicles include HC, NOx, CO, PM, etc. By applying technologies such as better catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the standard controls and reduces vehicle emissions below specified limits. 2. China 5 Vehicles: These are vehicles that comply with the 'National Fifth-Phase Motor Vehicle Pollutant Emission Standard.' 3. China 6 Vehicles: The symbol for China 6 is 'China VI.' China has already issued the China 6 vehicle emission standard, which is divided into two phases: China 6a and China 6b. The China 6a phase was officially implemented in 2020, and the China 6b phase was officially implemented in 2023.
