Because of stricter regulations for heavy-duty commercial vehicles, a reduction in CO 2 emissions from the commercial vehicle fleet of approximately 25 % by 2027 is required in the USA; in Europe the reduction has to reach 30 % by 2030. Since the internal combustion engine will continue to be the pre dominant drive source for heavy long-distance transport in the foreseeable future, increasing the engine efficiency must make a significant contribution to achieving the targets. Accordingly, AVL has set itself the goal of achieving a brake thermal efficiency of 50 %. THERMODYNAMIC CONCEPTSThe intended engine concept is to be ready for series production by 2024 and is to be focused on base engine technol ogy without the use of waste heat re covery or hybridization [1]. However, in order to meet the requirements of future exhaust gas legislation, which will de mand significant NO x reduction under all operating conditions, it is necessary to apply Exhaust Gas Recirculation (EGR).A Brake Thermal Efficiency (BTE) of 50 % can be achieved by using several selected thermodynamic concepts.
