Usually we talk about the EGR system, the understanding is the exhaust gas recirculation system, by introducing exhaust gas into the combustion chamber, thereby reducing the peak of engine combustion, to achieve the purpose of reducing NOx emissions. Diesel vehicles use an external system, that is, a pipeline is connected between the exhaust pipe and…

1. What is the performance of unplugging the fuel metering unit? All the fuel enters the common rail pipe, causing the rail pressure to be too high, the pressure limiting valve opens, and the limp mode is entered. It is also easy to cause the oil temperature to rise, which is detrimental to the entire…
