Efforts to meet future legislated emission requirements including those for carbon dioxide are leading to considerable innovation for improved powertrain performance. Leading these efforts is of course, vehicle electrification in its various forms for mild hybrids, full hybrids (serial and parallel), range extenders, plug-in hybrids and battery electric vehicles. Internal combustion engines (ICEs) have too been making significant strides in improving efficiency especially through downsizing efforts. Such approaches usually rely on boosting together with the use of direct fuel injection. There are various additional strategies pursued by the OEMs that include design changes to engine air induction systems, various exhaust gas recirculation (EGR) and cooling architectures together with suitable control strategies.
The accompanying exhibit shows the myriad of technological offerings open to the automotive OEMs for realizing improvements in combustion efficiency through modifications to engine air induction, cooling, boosting and EGR systems. The pressure boosting of engine intake air is a key factor behind the success of downsized engines for improved fuel economy. This has placed new requirements on air induction and cooling systems as a result of the need to incorporate and cool charged air. Modern methodologies enable engine engineers to more closely control both the pressure and temperature of the charged air with a resultant improvement in combustion efficiency.
The use of EGR has been embraced as a means of improving engine efficiency and reducing engine emissions. Various approaches are used including internal recirculation and low and high pressure EGR systems. The EGR technology selected impacts both the air induction and cooling system architectures.
Cooling systems in the past have focused on minimizing component costs while fulfilling non-optimized engine requirements. Investments in advanced thermal management technologies offer significant performance improvements. Variable speed pumps and/or electronic coolant flow control are being developed. Such approaches minimize flow of coolant to the engine during warm-up but optimize coolant flow during warm engine operation so as to minimize friction and maximize engine thermodynamic efficiency.
ITB’s new report provides an in-depth analysis of these examples and integrates this analysis with the overall business, legislative and technical developments impacting the automotive engine air and cooling market. In addition, the report features a chapter on engineering thermoplastic developments due to the important role they play in enabling the success of today’s air induction and cooling systems.
