FUEL SYSTEM [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)]

id0114q5002600


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.
