FUEL SYSTEM [SKYACTIV-X 2.0]

id0114hf002600


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.
•  A brushless motor has been adopted in the fuel pump unit for improved fuel economy. Using the brushless motor, the fuel pump function is improved and a stabilized fuel supply is achieved.
