BorgWarner’s EGR tech debuts on Hyundai-Kia hybrids

0

BorgWarner supplies its advanced exhaust gas recirculation (EGR) valve for the new Hyundai Ioniq sedan and the Kia Niro crossover sport utility vehicles. These gasoline and hybrid vehicles are powered by the 1.6-liter gasoline direct-injected (GDI) Kappa engine, expected to drive a growing line-up of hybrid models from the auto makers. BorgWarner’s compact, optimized EGR valve contributes to the vehicles’ lower emissions and 3% increase in fuel economy.

“Our years of gasoline and diesel EGR experience along with our deep engine system knowledge drove us to develop a new EGR valve designed specifically for the unique requirements of today’s advanced gasoline engines,” said Brady Ericson, president and general manager, BorgWarner Emissions Systems.

“BorgWarner’s new low-pressure EGR technology offers auto makers a compact, reliable and cost-effective method for improving fuel economy and reducing emissions, and is fast becoming the standard solution for gasoline hybrid propulsion systems. We are pleased to contribute our EGR technology to a growing list of Hyundai and Kia vehicles.”

Precisely regulating EGR throughout a range of rpms and loads reduces high temperatures in the combustion chamber, enabling a variety of strategies aimed at improving engine efficiency and fuel economy. For example, using cooled EGR manages pumping losses to help the engine run more efficiently, improves combustion timing for a leaner burn without knocking and helps avoid using enriched fuel/air mixtures, which saves fuel.

The technology also reduces carbon monoxide (CO) and nitrogen oxide (NOx) emissions as well as particulate matter (PM). Unlike competitive models, BorgWarner’s EGR valve delivers superior accuracy by measuring valve lift directly. The simplified, low-leak design also resists sticking and uses fewer parts in the gear train, resulting in a compact, cost-effective solution with 25% faster response compared with previous models.
