Effectively reducing the levels of oxides of nitrogen (NOx) is what your Infiniti I30 exhaust gas recirculation (EGR) valve is all about. Mounted right at the exhaust manifold, the part forms a vacuum through its diaphragm to effectively route exhaust gases to designated pipes and chambers. For computer assisted engine assemblies, EGR valves make use of one of more solenoids or steeper motors to effectively manage and manipulate gas flow. While it only opens once your engine already has warmed up or already runs as part-throttle, the part therefore requires certain amount of back pressure to be operated. You can easily determine when the part starts fouling up for your vehicle will surely run differently. Once the valve stick in open position or fails to close in time, vacuum leaks might be formed and cause rough idle, hesitation, and stalling. Once the valve fails to open, NOx gas compounds might rise within exhaust pipes or combustion chambers that may cause detonation.
During fuel combustion operations, nitrogen and oxygen gases in the air along with hydrocarbons reacts and combines with water and carbon dioxide. This chemical reaction leaves nitrogen unchanged. When engine heat tends to build-up, nitrogen reacts with combustion by-products which are water and ozone and therefore from NOx. Your engine employs EGR valve to limit the production of NOx. Because this gas compound is formed only at high engine temperature, the part facilitates intermixing of incoming air with re-circulated fuel exhaust gases to dilute the mixture of toxic gas emission. This way, exhaust gases increases the specific heat capacity of the gas mixtures which then lowers the peak combustion temperatures.
While practical EGR valve applications come with tremendous fuel efficiency as well as performance gains, it also has restrictions to applications. As it increases inlet manifold pressure, the part reduces throttling losses. To reduce heat rejection, the part prevents losses to the thermal energy at combustion chamber surfaces in lowering peak combustion temperature. By doing so, more energy will be produced by fuel combustion operations as it reduces chemical dissociation. However, EGR valve applications are not fitted for high load driving applications as it might lead to reduce peak power output. Also, it is not to be used at idle or zero load and low-speed driving applications for it might cause rough idle.
Because stock EGR valves are exposed to virtually the harshest working environment, it is bound to fail with age. Once the part starts fouling up, it needs professional service. Because EGR valves are electronic parts, it needs special mechanical skills and knowledge to be fixed.
