Abstract:
This paper describes a new 1.6-liter four-cylinder gasoline turbocharged engine with a direct injection gasoline (DIG) system and a twin continuously variable valve timing control (CVTC) system. Demands for higher environmental performance make it necessary to improve engine efficiency further. At the same time, improvement of power performance is important to enhance the appeal of vehicles and make them attractive to consumers.In order to meet these requirements, a 1.6-liter direct injection gasoline turbocharged engine has been developed. By using many friction reduction technologys, this engine achieves the high power performance of a 2.5-liter NA(Naturally Aspirated) gasoline engine and low fuel consumption comparable to that of a smaller displacement engine. In addition, this engine achieves low exhaust emission performance to comply with the US LEV2-ULEV and EU Euro5 emission requirements.This engine has been named MR16DDT, and the first vehicle fitted with MR16DDT engine is the Juke.This paper describes in detail the technologies incorporated in this new engine.
