The ICCT team—John German and Aaron Isenstadt—concluded that diesels have and will retain two significant advantages over gasoline engines: significantly better fuel economy and cargo hauling and towing ability. Meeting the 2025 standard will require an average improvement in fuel economy of about 4.1%

Manufacturers continue to optimize diesel emission controls, such as DOC, DPF and SCR, in order to promote uniform catalyst coating, improve NO x conversion efficiency, reduce back pressure on the engine, and reduce thermal mass. Better catalysts and urea dosing systems can achieve high NOx conversion during lower temperature operation.

Thanks to this rightsizing approach, the new engine enjoys the consumption benefits of a downsizing engine in partial load operation, while at higher loads it has the advantages of a large-displacement engine. The result is optimal efficiency and performance characteristics across the entire engine speed range. Stroppiana, A.,
