Development trends in heavy-duty diesel engines

Abstract

736 Development trends in heavy-duty diesel engines parallel, manufacturers need to control the cost of hardware and find ways to reduce the cost of operation at the customer side. CO 2 Regulation The big success of CO 2 regulations for passenger cars will lead to challenging limits for commercial vehicles. The variety of vehicle types and operation modes makes a certification on a rolling road test difficult -almost all regulatory approaches use simulation methods. The EU will have the most advanced tool "VECTO" which is currently under verification. The EU Commission plans to use VECTO first as a labelling tool; between 2018 and 2020 a regulation comparable to passenger cars is most likely. Requirements of 20-30% CO 2 -reduction are to be expected and will completely change the commercial vehicle drivetrain. Development Trends in Heavy Duty Diesel Engines -Prof. Dr.-Ing. Karl Viktor Schaller Heavy duty diesel engines will be heavily influenced by the upcoming EU and EPA CO 2 limits. In parallel, manufacturers need to control the cost of hardware and find ways to reduce the cost of operation at the customer side.
