2Ohm Red Coil CNG LPG Autogas Rail Injector for Car Kit
This injector rail uses a listed 2 Ω red-coil configuration. It meters gaseous fuel under ECU control in a compatible sequential injection system. Confirm the fuel specification, injector-driver requirements and rail configuration before ordering.
The rail supplies gas to the engine intake through the installed outlet connections. It should not be described as a gasoline direct injector. Engine compatibility depends on the complete gas system and calibration.
Technical Specifications
Specifications must match the supplied rail variant. Confirm the following listed values against the model-specific technical sheet and test conditions.
| Standard Listed Configuration | 2 Ω red coil |
|---|---|
| Fuel Application | Confirm CNG or LPG suitability for the selected variant |
| Listed Operating Voltage | 12 V DC ±10%; confirm the required injector drive strategy |
| Listed Operating Pressure | 0.5–2.5 bar; confirm whether gauge, absolute or differential pressure |
| Listed Temperature Range | −20°C to +120°C; confirm operating and test conditions |
| Listed Operating Frequency | 150 Hz; request pulse duration, duty cycle and test conditions |
| Listed Opening Time | 2.5 ms ±5%; request electrical and pressure conditions |
| Listed Closing Time | 2.0 ms ±5%; request electrical and pressure conditions |
| Nozzle Specification | Confirm outlet bore dimensions, tolerance and corresponding flow data |
| Other Resistance Options | Listed options: 1 Ω, 3 Ω and 6 Ω; confirm availability and compatibility |
| Other Coil Colors | Listed options: silver, blue, black and orange; confirm configuration |
Coil color is not a universal electrical specification. Confirm resistance and drive requirements from the product documentation rather than identifying compatibility by color alone.
Will This Rail Match Your ECU?
ECU compatibility requires more than a matching resistance value. Confirm current control, drive strategy, connector type and supported injector calibration.
Electrical: Coil resistance, tolerance and injector-driver compatibility.
Mechanical: Mounting dimensions, inlet size, outlet connections and clearance.
Gas delivery: Fuel type, operating pressure, nozzle configuration and required flow.
Calibration: Injector settings and pressure compensation supported by the ECU.
Different cylinder counts require the appropriate rail arrangement. The listed range includes 2-, 3-, 4-, 6- and 8-cylinder configurations. Confirm the number of injector channels and rail assemblies in the quotation.
Calibration must match the installed components. Read our injector rail and ECU calibration guide for related information.
How Should Pressure and Nozzle Data Be Checked?
Operating pressure and pressure-test limits are different specifications. Request the rated operating range, pressure reference and documented test limits. A proof or test pressure must not be treated as a continuous operating rating.
A dimension in millimeters describes geometry, not flow rate. Request the nozzle bore diameter and tolerance, then obtain flow data for that configuration. Do not use a nozzle size alone to estimate supported engine power.
Pressure reference: Gauge, absolute or differential pressure.
Flow measurement: Test gas, pressure, temperature and measurement unit.
Measurement scope: One injector channel or the complete rail.
Pulse conditions: Frequency, pulse duration and duty cycle.
What Supports the Response-Time Claims?
Opening and closing times depend on the measurement conditions. Request the test voltage or current profile, gas pressure, temperature and measurement method supporting the listed values.
Identify the tested rail and coil variant.
State the electrical drive conditions.
Record the gas pressure and temperature.
Define the opening and closing measurement thresholds.
Provide the permitted variation and recorded results.
Material descriptions do not establish service life. The product information lists a stainless-steel internal magnetic tube. Request durability or wear-test data before making a quantified lifetime comparison.
Which Quality Records Should Buyers Request?
Inspection records should identify the product and acceptance criteria. Request the checks applicable to the rail in your order.
Coil inspection: Resistance, measurement temperature and tolerance.
Leak testing: Test medium, pressure, duration and acceptance limit.
Flow consistency: Channel-to-channel results under defined conditions.
Response testing: Opening and closing measurements.
Traceability: Batch or serial reference and inspection date.
Approval documents must cover the purchased variant. Review our certification information and request applicable model-specific records.
What Other Components Are Required?
The injector rail is one component of the conversion system. Confirm compatibility with the gas ECU, regulator, sensors, filter, hoses and fittings.
The quotation defines what is included. Review our conversion kit component guide when comparing a rail-only offer with a wider component package.
Frequently Asked Questions
Can a red 2 Ω coil be replaced with another resistance?
Do not substitute resistance variants without checking ECU compatibility. Confirm driver requirements, injector characteristics and calibration changes before replacement.
Can the same rail operate with CNG and LPG?
Fuel suitability must be confirmed for the selected variant. Check materials, seals, pressure ratings and technical documentation. Neither coil color nor resistance alone establishes fuel compatibility.
Does the rail improve engine power?
No fixed power improvement is established by this page. Results depend on engine condition, gas supply, component matching and calibration.
What should be checked when idle becomes unstable?
Unstable idle can have several causes. Qualified technicians should check engine condition, pressure, filters, wiring, sensors and injector operation before replacing parts.
How should the rail be maintained?
Follow the component manufacturer's service instructions. Use approved inspection and repair procedures. Our gas system maintenance guide provides background information.
