Our factory YC112 series CNG LPG injector rail is a critical core component for vehicle multi-point electronically controlled gas injection systems. This 3Ohm 4-cylinder common injector rail assembly consists of solenoid coils, precision valve nozzles and high-strength rail body. The built-in nozzle quantity perfectly matches 4-cylinder gasoline engines for CNG or LPG dual-fuel conversion. We also supply other variants covering 1cyl, 2cyl, 3cyl, 6cyl and 8cylinder to fit diverse engine requirements for passenger cars, taxis and light commercial vehicles.
Manufactured with precise CNC machining and advanced high-tech assembly technology, this natural gas fuel injector rail delivers stable gas metering performance. It is universally compatible with most autogas ECUs and conversion kits for petrol-to-gas retrofit projects worldwide.

Frequently Asked Questions
Q1: What vehicles fit the 3Ohm 4-cylinder common injector rail?
A1: It applies to most 4-cylinder multi-point port injection gasoline vehicles for CNG gas conversion. 2Ohm variant is recommended for LPG projects. We also provide 1/2/3/6/8-cylinder models for different engine displacements.
Q2: Can this injector rail work with third-party autogas ECUs?
A2: Yes, this YC112 injector rail has wide compatibility and can cooperate with most mainstream multipoint sequential autogas ECUs on market.
Q3: How to maintain CNG LPG injector rail during daily usage?
A3: Regular cleaning for nozzles is suggested to avoid gas impurity blockage. Dismantle and flush the nozzles when you notice unstable idle speed or power drop under gas mode.
Q4: Do you support custom specifications for injector rail?
A4: Yes. Our R&D team accepts OEM ODM orders, we can adjust resistance, flow rate and appearance according to customer drawings and technical requirements.
Q5: What is your warranty policy for injector rail products?
A5: Our injector rails enjoy 1-2 years factory warranty for manufacturing defects, excluding damage caused by improper installation or bad fuel impurities.
Q6: What spare parts should match together with injector rail?
A6: To finish full gas conversion system, you need to match autogas ECU, pressure reducer, pressure sensor, gas hose and relevant pipe fittings.
