    I know this is a technical post and should be posted in tech, but I also know that a large number of folks dont even bother to read the technical forum (you know who you are) and I feel that this writeup needs to reach as many folks as possible. Over the years I have had numerous incidences where I [read more]
EGR Removal/Replacement

EGR Valve Replacement: When optimal air/fuel mixture is attained (14.7:1), the combustion process creates several different nitrogen oxides (NOx) because the combustion chamber is operating at over 2000° F . To reduce the NOx emission, the combustion chamber temp must be lowered. So the Exhaust Gas Recirculation (EGR) valve (generic diagram 1.) recirculates the now inert exhaust gas back into [read more]

Understanding Exhaust Gas Recirculation Systems Posted 11/5/1997 By Henry Guzman Exhaust gas recirculation (EGR) systems were introduced in the early '70s to reduce an exhaust emission that was not being cleaned by the other smog controls. Oxides of nitrogen (NOx) are formed when temperatures in the combustion chamber get too hot. At 2500 degrees Fahrenheit or hotter, the nitrogen and [read more]
