Gasket Systems with Integral Filter Elements for Low-pressure Exhaust Gas Recirculation
- 102 Downloads
In exhaust gas recirculation systems, the gaskets used to seal the components that the exhaust gas passes through have to meet high standards of quality, including resistance to high temperatures and aggressive substances. An additional requirement in low-pressure exhaust gas recirculation processes is the use of a filter to protect the turbocharger from mechanical damage caused by solid particles. ElringKlinger and GKD – Gebr. Kufferath AG have developed a system consisting of gaskets and filters specially for this purpose.
Exhaust gas recirculation (EGR) has a long tradition. It was recognised as a very effective solution for the reduction of nitric oxide from diesel engines as early as 1973 and towards the end of the 1980s became a standard volume production part for direct-injection diesel engines fitted to passenger cars. Although this brought considerable fuel consumption advantages compared to the conventional combustion chamber diesel engine, NOxemissions were...
