What does EGR do on a motorcycle?
A mechanical exhaust gas recirculation (EGR in brief) system has been developed for motorcycles and attempt to reduce NOx exhaust emission as a valuable method.
What happens if you dont clean EGR?
If the EGR valve is stuck open, it will essentially cause a vacuum leak, leading to inefficient combustion, rough idling, hesitation, and sometimes stalling in extreme cases. This is because the car cannot combust on carbon dioxide from the tailpipe — it needs atmospheric oxygen.
Does overlap reduce HC emissions?
In this study, the strategy of varying the valve overlap was employed to reduce methane emissions. Although a torque valve cannot meet engine emission specifications, the hydrocarbon and methane emissions were reduced by approximately 41% by decreasing the valve overlap duration while using HCNG fuel.
What is EGR PDF?
Exhaust gas recirculation (EGR) is a pre-treatment technique. This is the widely used process to reduce and control the oxides. of nitrogen (NOx) emissions from diesel engines.
Can EGR be cleaned?
To clean the valve, wear an acid-resistant pair of gloves. Put on safety glasses, too, as the carbon deposits could become airborne in the process. Spray the EGR valve cleaner onto the carbon deposits. Remove the carbon buildup with the use of a pipe cleaning brush and dull scraper.
Can EGR valve cause knocking?
Knocking noises from the engine can be caused if the EGR is constantly closed. This is because at low rpm the fuel ignites early when it meets the high temperature. Detonations are also common as a second ignition can occur after the normal ignition.
Can EGR cause misfire?
It is also possible for an EGR valve to leak, causing a random misfire. The next thing you should check is the fuel pressure with a gauge. In addition to leaking pressure, a bad fuel pressure relay can also prevent a good fuel pump from delivering full pressure to the injectors as well.
