Kia Optima EGR Valve

In Kia Optima vehicles, the EGR Valve is used to regulate the rerouting of exhaust gases back to the combustion chamber with the intention of minimizing nitrogen oxide (NOx) emissions. The EGR Valve reintroduces a part of the exhaust emissions into the engine to reduced the oxygen content in the cylinder and adding inert gases which have heat absorption ability; preventing high temperatures that cause NOx production hence controlling emissions. It also further refines the efficiency of engines; more prevalent in petrol engines, by permitting an improved throttle position and reduced pumping losses. In Optima, Kia has used orifice jets to basic orifice jets or more complex valves that adapt to the condition of the coolant temperature and manifold vacuum. Contemporary EGR systems may also use backpressure transducers to adapt the flow with regard to the load in the engine. Although they are useful in keeping emission low EGR Valces used in Kia Optima cars may be choked by carbon deposits and need to be cleaned for the prime performance.
