The scenario
Automotive fuel system P&ID for high-pressure direct injection on a 2015 Ford Mustang EcoBoost, covering supply, filtration, high-pressure delivery, injection, and return control.
What is in this drawing
Read the decisions behind it.
01
Used pump_pd for the high-pressure fuel pump and pump_centrifugal for the in-tank lift pump.
02
Added FT/FIC and PT/PIC loops for fuel flow and rail pressure control.
03
Represented the direct injector as valve_control with electric control signal from FIC.
When modeling automotive liquid fuel systems, especially direct injection return-type circuits with pressure regulation and pump speed control.
