- Summary
- In a gasoline direct injection (GDI) engine, highly pressurized gasoline is injected via a common rail fuel line and injectors that deliver fuel directly into the combustion chamber of each cylinder. In comparison, in a conventional multi-point fuel injection (MPI) engine, relatively low pressure gasoline is injected into the intake port of each cylinder. Due to high fuel pressures in a GDI system, servicing the GDI system requires special attention and handling procedures. This bulletin provides special service information and specification for the GDI fuel system components.
