Exhaust Gas Recirculation (EGR)
Land Vehicle and Diesel Engine
EGR IS CURRENTLY USED FOR ON HIGHWAY APPLICATIONS AS A METHOD OF MEETING THE STRINGENT EMISSIONS LEGISLATION.
Exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR is currently used as a method of meeting the stringent emissions legislation that applies to passenger car and on / off highway engine applications.
EGR works by recirculating a proportion of an engine’s exhaust gas back to the engine cylinders.
In a diesel engine, the exhaust gas replaces some of the excess oxygen in the pre-combustion mixture and 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 process generates. Most modern engines now require exhaust gas recirculation to meet emissions standards.
Senior Flexonics uses its highly flexible plate design heat exchanger technology which will vary in size depending on the engine size and the emission standard the engine must comply with. Senior Flexonics design and develop solutions to meet the exact requirement of the customer and application.
