BorgWarner has announced it is supplying compact EGR valves for the Hyundai-Kia 1.6-litre GDI Kappa petrol engines used in the recently launched Hyundai Ioniq sedan and Kia Niro crossover SUV vehicle ranges.
The supplier said the gasoline direct injected (GDI) engine is expected to drive a growing line-up of hybrid models from both automakers and its optimised 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.
BW said precisely regulating EGR throughout a range of engine speeds and loads reduces high temperatures in the combustion chamber, enabling a variety of strategies aimed at improving engine efficiency and fuel economy. 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 components, BorgWarner claims, its 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 part with 25% faster response compared with previous models.
