Most diesel engines in the U.S. use a combination of technologies to reduce emissions. Usually there will be a diesel particulate filter (DPF), selective catalytic reduction (SCR) with urea (DEF fluid ...

ABSTRACT Exhaust gas recirculation (EGR) is effective in reducing engine-out NOₓ emissions; however, the EGR system is subject to fouling and corrosion. Fouling is mainly due to particulate buildup on ...

While most of the early problems have been engineered out of the exhaust gas recirculation systems on today’s clean diesel engines, corroded coolers, stuck valves and other problems still plague ...

ABSTRACT The buildup of deposits in EGR coolers causes significant degradation in heat transfer performance, often on the order of 20-30%. Deposits also increase pressure drop across coolers and thus ...

Two critical elements that need to be checked out at 100,000 miles are the EGR valve and the DPF. Hasten says to run a computerized flow test on the DPF filter tol show if the filter in the exhaust ...

Contracts for two different exhaust gas recirculation (EGR) coolers awarded Result of strong relationship development and technology leadership Proprietary compact floating core architecture enables ...
