DiesOtto
The DiesOtto motor is an experimental automobile engine that "is said to incorporate the benefits of a diesel engine, but runs on gasoline instead." Its name is a portmanteau of Diesel and Otto, referring to the Diesel engine, first introduced by German engineer Rudolf Diesel, and the Otto cycle, as a reference to Nicolaus Otto (even though the invention of the gasoline engine is variously attributed to both Nicolaus Otto and Alphonse Beau de Rochas). As of 2017, the only company which announced to launch a car with a DiesOtto motor is Mazda, with SKYACTIV-X. == Engine characteristics and principles of operation == The concept engine has an in-line, four-cylinder configuration and displaces 1.8 litres.
