High Pressure Common Rail PCM106

Overview

This High pressure Common Rail (Common Rail) EFI

technology refers to A closed loop system composed of

high pressure oil pump, pressure sensor and electronic

control unit (ECU), the injection pressure generation

And injection process are completely separate from

Each other a way of oil supply This series of sensors is

Divided into A and B structure, that is, PCM36A series

And PCM36B series, wide measuring range, It is widely

Used in the control system unit of diesel vehicles.
