Waste Heat Recovery and LP EGR Integrated System

With the upcoming new emissions regulations, cold-start will have a big impact on the overall homologation cycles where both emissions and fuel consumption are directly penalized by the time the engine runs in cold conditions. At the same time, the use of cooled EGR during that cycle is a very widespread strategy between OEMs. BorgWarner presents solutions for both aspects in the same product where a low pressure EGR system is integrated with an Waste Heat Recovery System (WHRS) that helps to reduce the engine warm-up time and hence reduces the overall cycle consumption and emissions. Apart from compactness and serviceability, the module directly assembled close coupled to after treatment recovers most available heat without conduction losses.
