Analysis of EGR emission reduction technique

In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders.

 In a gasoline 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. The principal function of EGR to reduce the amount of NOX that is produced during the combustion process Nox is created by high combustion temperature that allowed the Nitrogen and Oxygen to combined and form Nitrogen Oxide. A combustion temperature of at least 2500 degree is required to form Nitrogen oxide. We use exhaust gases to curb that temperature inside  the chamber.




Project Idea :

This idea is to understand details of the thermal and mechanical properties of the deposit layer, and how they are affected by operating conditions, The student will work with our group to improve test hardware, conduct experiments, and interpret results. It will provide hands on experience in a modern engine test cell with an advanced heat transfer study.
