BorgWarner supplies EGR cooler with new hybrid tube tech for Renault’s 1.6 diesel engine

July 18, 2013: BorgWarner has supplied its latest exhaust gas recirculation (EGR) cooler for Renault’s 1.6-litre diesel engine, available on the European Scénic and Mégane as well as Nissan’s Qashqai crossover. The company claims its advanced EGR cooler with integrated hybrid tube technology helps improve fuel economy up to 3 percent while helping to achieve upcoming Euro 6 emissions standards. The combination of its optimised turbocharger and latest compact EGR technology meets future engine requirements with improved durability.

“BorgWarner’s advanced EGR solutions, combined with our optimised turbocharging technology, is a major step in enabling diesel engines to meet future emissions regulations while improving fuel economy,” said Brady Ericson, president and general manager, BorgWarner Emissions Systems. “With our many years of experience, BorgWarner offers customers the latest compact, low-pressure EGR technology. We expect this effective, fast-growing technology to drive engine advancements in the future.”

Renault’s powertrain strategy includes a low-pressure, compact EGR system. Although low-pressure EGR systems offer lower emissions and better fuel economy than high-pressure systems, components in low-pressure EGR systems must withstand extreme loads and damaging particles. BorgWarner’s EGR cooler technology employs highly corrosion-resistant stainless steel hybrid tubes inside the cooler to quickly reduce the temperature of hot exhaust gases. The specially shaped hybrid tubes keep exhaust gases moving at high speeds to increase EGR rates as well as avoid soot and hydrocarbon build-up. The system also features an integrated hydro formed EGR tube to guide exhaust gases into the cooler and a metallic EGR filter with optimised permeability to protect the turbocharger compressor wheel by filtering out any remaining particulates.
