Exhaust Gas Recirculation
EGR is a NOx (nitrogen oxide and nitrogen dioxide) reduction technique used in most gasoline and diesel engines.
EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. Intermixing the incoming air with recirculated exhaust gas dilutes the mix with inert gas, lowering the adiabatic flame temperature and (in diesel engines) reducing the amount of excess oxygen. The exhaust gas also increases the specific heat capacity of the mix lowering the peak combustion temperature. Because NOx formation progresses much faster at high temperatures, EGR serves to limit the generation of NOx. NOx is primarily formed when a mix of nitrogen and oxygen is subjected to high temperatures.
Currently in purney's garage: laguna 1.9dci privilege sport tourer
My T reg 1999 Laguna has 158,000 on the clock Engine, steering, suspension and body is all in excellent condition except for sunroof problem.
My last car, a Clio dci 1.5 80hp Expression, had 104000 on the clock when I traded it in at 24 months old. Not one fault and only tyres and pads changed.
My previous car, A Clio dci 65hp Expression, had 128000 on the clock after 20 months. That car had a new alternator at 94000 miles.
Here's to my new Modus being as reliable.
(I'm a driving instructor by the way).
