The EGR is usually located on the inlet manifold of the engine, although sometimes it can be located lower down near the exhaust manifold. It operates by recirculating exhaust gas back into the engine through the intake. This gas is cooler than the combustion temperature inside the cylinder, which reduces the production of oxides of nitrogen.

Additives in premium diesel fuel help reduce fouling of the EGR valve, EGR cooler and turbocharger. A typical #2 diesel can burn incompletely and leave deposits.

EGR is not the devil most think it is as GDE has greatly cleaned up the combustion so less soot is being sent into the intake from the EGR. Don't let the active EGR stop you from buying a great tune package. Feedback so far looks great. In simple terms, the wastegate on a diesel engine creates a “leak” in the exhaust side of the turbocharger when the pressure gets to be too much. The intake side has an actuator that measures the amount of air going in. As the pressure or boost increases, the actuator will begin to open the wastegate on the exhaust side. The Diesel Particulate Filter (DPF) is an assist in emissions-control included within diesel exhaust systems, to catch the remaining particulates left within the combustion cycle of the diesel engine. Each combustion cycle within a diesel engine includes un-burnt components of diesel fuel, carbon, and other particulates that accumulate into . 232 94 385 44 231 280 18 443
