Reducing emissions for rail, mining, and oil & gas applications

COOLED exhaust gas recirculation (EGR) is one of the most effective methods of reducing nitrogen oxide (NO) emissions in large diesel engines. BorgWarner is expanding applications and markets for its EGR coolers with Tognum MTU-brand diesel engines for off-highway applications. The MTU Series 1600, 2000 and 4000 engines are used to power locomotives, mining equipment and pumps for the oil and gas industry. These multiple-core EGR coolers help reduce emissions in MTU diesel engines using an innovative modular design concept that allows a high level of customisation and performance for a wide variety of applications with limited production volumes.

“BorgWarner engineers have been working closely with MTU to develop cooled EGR for heavy industrial diesel engine applications that demand both reliability and economy in extremely harsh environments,” said Brady Ericson, president and general manager, BorgWarner Emissions Systems.

The EGR coolers utilise specially designed hybrid tubes to optimise heat transfer and deliver superior heat rejection with less hydrocarbon build-up. The floating core and optimised coolant flow increase durability during extreme thermal loads typical in these applications, and anti-vibration clips help withstand the vibration expected in heavy-duty industrial engines. To minimise development times, tooling costs and investments whilst meeting the technical requirements of a broad range of engines and applications, the modular design provides customised performance by using multiple EGR cooler cores with a high percentage of common parts. Depending on the application, these can help engine manufacturers meet stringent emissions standards without any NO after-treatment technology.
