The EGR Valve in Pontiac Grand Prix automobiles assisting the flow of exhaust gases back to the combustion chamber that helps in minimizing the Nitrogen oxide (NOx) emission. It reduces the concentration of oxygen by passing a part of the exhaust gas back in to the intake manifold through a device known as the EGR Valve, this reduces inert gases and dilutes the combustion heat thus reducing NOx resulting from the high temperatures. This mechanism not only helps in achieving the emission targets but also helps in improving the engines performance as it offer higher throttle positions and lesser pumping losses. Throughout the years, some of the Pontiac Grand Prix cars uses have included various forms of EGR Valves ranging from simple orifice jets on to valves that are controlled by coolant temperature and manifold vacuum. Current EGR systems may comprise back pressure transducers for controlling the flow according to the load requirement of the engine. However, EGR Valves used in Pontiac Grand Prix vehicles work effectively as desired but has the problem of being blocked by carbon deposits which makes it requires frequent cleaning.
