Modification of the secondary air inlet of Chery Ruiqi? Come on, everybody, 3Q.

The modification of Chery Ruiqi still depends on which car it is, such as M 1 M5. As for G5, it is possible to modify the secondary circuit, but you have a misunderstanding about the purpose of the secondary circuit. The secondary loop mainly solves the emission standard problem, not the power problem. If you want to supercharge the exhaust gas into the cylinder, you might as well add a twin turbocharging engine, that is, DETT engine (D stands for DOHC, E stands for electronic oil injection, TT means twin turbocharging. The working principle of the secondary loop is mainly used when the car is cold. Because the concentration of mixed gas below 40℃ is relatively high in cold state, the secondary air intake starts to work for 30-90 seconds, and the gas is directly supplied to the exhaust branch pipe, so that the burning waste can be combusted for the second time and then cleaned. This is his main purpose, not to improve the power of the engine. For example, the 4G63 of Mitsubishi EVO and the EJ20 engine of Subaru were all modified by the factory because they could not meet the statutory emission standards.
