ENGINE EXHAUST GAS RECIRCULATION SYSTEM MONITOR FREE
Now, the exhaust gases are inert gases because they have already been burnt and free oxygen is not present in the exhaust gases. Once mixed, the concentration of the oxygen in the fresh air is reduced and the temperature of the fresh air is increased slightly. This valve opens and redirects some of the exhaust gases back to the intake manifold, where these are mixed with fresh air. There is an EGR-valve fixed after the exhaust manifold and before the catalytic converter. The working of this process is fairly simple but the implications are impressive. Governments are always bringing in tougher emission regulations to keep the environmental pollution in check and the customers are looking for more powerful or more fuel-efficient cars at the same time.ĮGR – Exhaust Gas Recirculation – Working That is the reason why so much research has gone into these aspects and new technologies keep coming up as the emission and performance requirements keep on increasing. As we know, the quality of air inside the combustion chamber, the ignition process, pressure and temperature inside the engine decide all the performance, fuel and emission parameters and output of a car, tweaking these could bring in a ton of benefits in all these regards. This could range from controlling the temperature inside the combustion chamber to improving the fuel economy of a car and everything in between. EGR – Exhaust Gas Recirculation – Principle and NeedĪs the term suggests, Exhaust Gas Recirculation refers to the redirection of the exhaust gases after the combustion process and use it to achieve various goals in the engine of the vehicle.
