📖 DEFINED CALIBRATION CONCEPT · v1.0.44
Common-Rail Fuel Pressure (bar) & Metering Control
Modern common-rail diesel systems (1,600 bar on EDC16 up to 2,500–2,700 bar on Bosch MD1 / Denso Gen3) atomize fuel via high-pressure pumps regulated by an inlet Metering Unit (IMV/ZME) and rail Pressure Control Valve (PCV/DRV).
Practical Workshop & Calibration Engineering Application
Safe Stage 1 calibration adds modest rail pressure only in upper load/RPM zones while keeping factory rail relief limits active.
