PT414-B High-Precision Cummins Fuel Injector Calibration and Test Bench

Cummins PT Fuel System Platform

The PT test bench is purpose-built for Cummins PT (Pressure-Time) fuel injection systems used in heavy-duty diesel engines. The PT type system uses a mechanical governor with fuel pressure and injection timing controlled by the rotary throttling action of the PT pump. Supported engine families include Cummins N14 / NTA855 / M11 / ISM / ISX / QSX / QSK / K19 / K38 / K50, and Cummins STC (Step Timing Control) / PT(K) / PT(G) / PT(GC) / PT(FCP) fuel systems.

PT Pump Calibration and Injector Testing Functions

The platform provides high-precision pressure measurement, flow rate analysis and air leakage detection for Cummins PT pumps and injectors. Calibration profiles cover idle speed, rated speed, full load and torque curve. Integrated mechanical governor testing allows verification of throttle shaft operation, idle spring tension and transfer pressure.
