As automotive manufacturers drive to more efficient solutions for fuel economy and performance, powertrain thermal management components must be optimized for heat transfer, weight, vehicle integration and total costs. Hybridization and electrification of powertrains increases the need for highly efficient thermal management solutions.
With the advent of stringent emissions regulations and improved fuel economy standards, the Exhaust Gas Recirculation Cooler (EGR-C) has become a critical component in both diesel and gasoline engine systems to reduce NOx (nitrous oxide) emissions and improve fuel economy. This is accomplished by returning cooled exhaust gas back to the engine. The EGR-C is designed to cool this recirculated exhaust gas with coolant, thereby reducing its volume and increasing its density. Modine was one of the first heat exchanger manufacturers to market with a light-duty automotive EGR-C.
Additionally, Modine works closely with the OEMs and intake manifold suppliers to integrate the LCAC into the intake manifold system for optimized performance and packaging. LCACs have typically been used as an aftercooler to cool the hot charge air to an acceptable level before entering the engine. With the introduction of series turbocharging, intercooling has also become necessary to reduce the charge air temperatures prior to being directed to the second compressor stage. This allows original equipment manufacturers flexibility to use lower cost materials for this second compressor.
