This 2-cylinder LPG CNG injector rail serves as an essential core assembly for two-cylinder vehicular gas sequential fuel injection conversion kits. It is composed of solenoid coils, precision valve nozzles and high-strength rail body. With exactly two built-in injection nozzles matching 2-cylinder gasoline engines, it delivers accurate and balanced gas supply for each cylinder during CNG or LPG dual-fuel retrofit. Manufactured with precise CNC machining process and advanced high-tech assembly technology, this injector rail maintains stable performance under varied engine-compartment working conditions.
This gas vehicular fuel injector rail fits two-cylinder passenger vehicles, small utility vehicles, motorcycles and light equipment engines for petrol-to-gas conversion. It can work cooperatively with autogas ECU, pressure reducer, gas hoses and other accessories to build a complete autogas conversion kit. We support factory bulk wholesale for global distributors, repair workshops and gas conversion project partners.

Frequently Asked Questions
Q1: What vehicles and engines fit this 2-cylinder injector rail?
A1: It is specially designed for 2-cylinder multi-point port injection gasoline engines, suitable for small cars, light utility vehicles and motorcycles for CNG or LPG dual-fuel conversion.
Q2: How to select proper resistance version for my injector rail?
A2: 2Ω version is recommended for LPG application, and 3Ω version works better for CNG system. Please confirm your autogas ECU driving requirement before placing orders.
Q3: Can this injector rail work with third-party brand autogas ECUs?
A3: Yes, it has wide compatibility with most mainstream sequential-type autogas ECUs. Please verify voltage and resistance parameters before installation.
Q4: What are common failure symptoms of 2-cylinder injector rail?
A4: Rough idle under gas mode, power drop, excessive gas consumption or gas leakage. Regular nozzle cleaning is advised; replace components if internal parts are permanently damaged.
Q5: Do you accept custom-made 2-cylinder injector rail?
A5: Yes, our R&D team supports OEM and ODM service, we can adjust resistance, flow rate and structure according to customer drawings and technical requirements for bulk orders.
Q6: What other spare parts are required to complete full gas conversion kit?
A6: You need to match autogas ECU, pressure reducer, pressure sensor, gas filter, gas hoses and relevant pipe fittings to complete the whole vehicular fuel injection system.
Q7: What is your warranty policy?
A7: We provide 1-2 years factory warranty against manufacturing defects. Damage caused by improper installation, impurity contamination or mechanical impact is not covered.
