Abstract

Strict emission standards are now in place that set specific limits to the amount that can be released into the environment. Reduction of exhaust emission of a vehicle is done through an EGR technique. EGR coolers are subjected to severe fouling such that their thermal efficiency can drop as much as 30 percent within a very short period of time. Durability of EGR cooler performance is key issue that affects the function of EGR system as anti-pollutant device. Decrease of thermal efficiency and increase of gas pressure drop caused by soot deposition implies higher EGR gas temperature and lower EGR flow. Selection of heat exchanger technology and definition of design parameters have an important effect on this degradation. This paper reviews a compendium of different tests, where different technologies and sizes of EGR cooler have been exposed to different engine test cycles. The focus is going to be mainly on Computation fluid dynamics (CFD) and to increase effectiveness of EGR cooler used in EGR system.
