FUEL SYSTEM [SKYACTIV-G 2.5]

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.
