Mazda CX-5 Service & Repair Manual: Fuel System
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.
