The combination of BorgWarner’s optimized turbocharger and its latest compact EGR technology fulfills future engine requirements with improved durability.

Renault’s powertrain strategy included 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 buildup.

The system also features an integrated hydroformed EGR tube to guide exhaust gases into the cooler and a metallic EGR filter with optimized permeability to protect the turbocharger compressor wheel by filtering out any remaining particulates.
