3Ohm 4-Cylinder CNG LPG Common Injector Rail
This four-cylinder injector rail meters gas under ECU control. The listed coil resistance is 3 Ω. Confirm the fuel specification, ECU driver compatibility and nozzle configuration before ordering.
Fuel suitability depends on the specific rail variant. Resistance alone does not establish CNG or LPG compatibility. Request the corresponding technical sheet and operating limits.
Technical Specifications
Electrical and flow specifications must match the installation. Confirm the following details for the supplied variant.
| Configuration | 4-cylinder gas injector rail |
|---|---|
| Listed Coil Resistance | 3 Ω; confirm tolerance and measurement temperature |
| Fuel Application | Confirm CNG or LPG suitability for the selected variant |
| ECU Requirements | Confirm drive voltage, current control and injector settings |
| Operating Pressure | Request the rated range and pressure reference |
| Flow Data | Request nozzle size, test gas, pressure and temperature |
| Response Time | Request opening and closing times with units and test conditions |
| Connections | Confirm electrical connector and gas connection dimensions |
Will This Rail Match Your ECU?
A matching resistance does not guarantee compatibility. Check the ECU driver, connector, wiring and calibration support before installation or replacement.
ECU: Provide the model and supported injector settings.
Electrical load: Confirm coil resistance and required drive strategy.
Connections: Compare connector type, pin assignment and mounting dimensions.
Gas delivery: Match pressure, nozzle configuration and required flow.
Calibration must match the installed rail. See our injector rail and ECU calibration guide for background information.
How Should Test Data Be Checked?
Flow and response values require stated test conditions. Ask whether measurements cover one injector channel or the complete rail. Compare results only under equivalent conditions.
Flow: Test gas, pressure difference, temperature, nozzle size and measurement unit.
Response: Opening and closing times, electrical drive conditions and gas pressure.
Leak testing: Test medium, pressure, duration and acceptance limit.
Consistency: Channel-to-channel flow variation and permitted tolerance.
Traceability: Product reference, batch and inspection date.
Patents and trademarks do not replace product test reports. Request applicable documents and check the covered product. Review our certification information.

Frequently Asked Questions
Does 3 Ω mean the rail is only for CNG?
No fuel application should be inferred from resistance alone. Confirm the variant's fuel compatibility, seals and pressure rating before use.
Can it replace another four-cylinder rail?
Replacement requires electrical and mechanical checks. Compare drive requirements, flow data, connections and mounting dimensions. Recalibrate according to the system instructions.
What should be checked if the engine idles unevenly?
Uneven idle does not identify one faulty component. Qualified technicians should check engine condition, gas pressure, filters, wiring, sensors and calibration. Follow approved service procedures before dismantling the rail.
What maintenance is required?
Follow the installed component's maintenance instructions. Request inspection intervals and approved service methods. See our gas system maintenance guide for background information.
What is included in the price?
The quotation defines the supply scope. Confirm the complete rail, nozzles, fittings and other accessories separately. Request warranty terms, packing details and lead time.
