Exhaust gas recirculation

June 30, 2014

Exhaust Gas Recirculation (EGR) is a nitrogen oxide emissions reduction technique used in petrol and diesel engines.
 

EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders.


In a petrol engine, this inert exhaust displaces the amount of combustible matter in the cylinder. In a diesel engine, the exhaust gas replaces some of the excess oxygen in the pre-combustion mixture. Because NOx forms primarily when a mixture of nitrogen and oxygen is subjected to high temperature, the lower combustion chamber temperatures caused by EGR reduces the amount of NOx the combustion generates. Most modern engines now require exhaust gas recirculation to meet emissions standards.

BG Diesel Air Induction & EGR service


The EGR service cleans more that just the EGR valve. Cleaning the EGR valve alone will be a very short term solution (at best) to the problems of accumulated deposits in the EGR system. The BG EGR service will clean the EGR valve and the channels (where most of the deposits accumulate).


This service will restore power and reduce Nox emissions
