Editing Diesel engine (section)

==Future developments==

In mid-2010s literature, main development goals for future diesel engines are described as improvements of exhaust emissions, reduction of fuel consumption, and increase of lifespan (2014).<ref name="Merker_2014_58" /><ref name="Reif_2014_11" /> It is said that the diesel engine, especially the diesel engine for commercial vehicles, will remain the most important vehicle powerplant until the mid-2030s. Editors assume that the complexity of the diesel engine will increase further (2014).<ref name="Merker_2014_273" /> Some editors expect a future convergency of diesel and [[Otto engine|Otto engines']] operating principles due to Otto engine development steps made towards [[homogeneous charge compression ignition]] (2017).<ref name="Stan_2017_252" />
