Pressure-tested. Calibrated. OEM-matched.
Every reducer and injector leaves our facility verified on a live-engine rig.
No generic stock—each unit carries OEM fitment data for the platform it serves.
Engine-specific parts, not shelf stock
Pressure Reducers
CNC-machined brass bodies, single and dual-stage variants. Fitment data verified for Changan, Chery, Geely, Foton, and Roewe platforms. Each unit ships with a pressure-test certificate.
Bore dimensions and inlet/outlet specs documented per engine family. Custom inlet tolerances available from our in-house CNC workshop with standard 7-day lead time.
Gas Injectors
Rail-mount injectors calibrated to OEM fuel-delivery maps for single-point, MPI, and GDI configurations. Flow rates measured on bench rigs before every shipment batch.
Injector sets paired with matching ECU pulse-width tables for Changan GDI, Chery MPI, and Geely Emgrand platforms—no manual remapping required at install.
Every unit on the rig before it ships
Reducers are bench-tested at rated inlet pressure with leak-down checks logged per unit. Injectors run calibration cycles on live-engine rigs—flow deviation outside ±2% is rejected and rebuilt.
Test certificates reference the serial number, test date, and platform spec. Distributors receive the certificate file with each order—ready for fleet audit or customs documentation.
