Saturn LS EGR Valve
The main function of the EGR Valve in Saturn LS vehicles is to control the flow of back pressure exhaust emission into the combustion chamber when the air-fuel ratio of the engine is off cycle hence, minimizing air pollution. This mechanism assists in reducing the level of nitrogen oxide (NOx) emissions through the re-circulation of part of the exhaust gas thus, reducing the maximum combustion temperature. In Saturn LS models, the EGR Valve contributes to better efficiency of the engine and decrease in emissions through the use of larger throttle positionings and reduction in pumping losses in petrol variants and substitution of excess oxygen in diesel variants to reduce combustion temperature. EGR works through restriction orifices jets but over the years, changes and improvements have been made in Saturn LS vehicles including coolant temperature, manifold vacuum among others. Contemporary EGR systems utilized in these automobiles employ backpressure transducers to tailor the flow in accordance with the demand of the engine. However, on the negative side, the EGR Valve is most times blocked with carbon and hence needs to be cleaned or replaced periodically to serve its intended purpose.
Each OEM Saturn LS EGR Valve we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
Saturn LS EGR Valve Parts Questions & Experts Answers
- Q: How Does the EGR System Reduce NOx Emissions, and how to Replace the EGR Valve and Pipe on Saturn LS?A: Nitrogen oxides NOx are those compounds formed in the combustion chamber with oxygen and nitrogen; in the incoming air normally above 2500 F temperatures When emitted from the car tail pipe the NOx combines with the reactive organic compounds, hydrocarbons and sun light to cause formation of ozone and photochemical smog. The EGR system work to reduce NOx emission; exhaust gases from the exhaust manifold are channeled by the EGR valve and then back to the intake manifold to mix with the air/fuel mixture thereby cooling the combustion chambers. This system comprises of the PCM, EGR valve, as well as the sensors that assist the PCM to decide the right time at which to open the EGR valve. When initialised, the EGR valve, has a position feedback circuit which accurately positions the pintle valve to enhance performance of the EGR system. Too much EGR flow might cause the engine to stall or has rough idle, as little flow might cause high combustion temperature, spark knock or overheating. In the case of EGR valve replacement unplug the electrical connector, then remove the bolts and extract the valve and its old gasket, before cleaning the contact surface and replacing the gasket with a new one then fixing the valve. For EGR pipe replacement, remove the nuts that connect the pipe to the intake and exhaust manifolds, remove the pipe, clean it well, apply anti seize on the threads and offer back the pipe, make sure that all nuts are right tight.
