FUEL SYSTEM [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5]

id0114zc002600


Purpose, Outline

•  A multiple hole type fuel injector has been adopted which provides higher fuel injection accuracy for improved fuel efficiency and output.
•  Piston movement-compression by the 4-head cam inside the high pressure fuel pump heightens the fuel pressure, achieving improved fuel efficiency and output.
