Independent LNG Fuel Injection Rail for Vehicle Gas Conversion
We are a professional manufacturer of full-series LPG, CNG and LNG automotive gas conversion components. The LNG Single Injector Rail is a core standalone fuel injection part for LNG vehicle systems. The independent single-nozzle structure offers steady injection accuracy and flexible installation, with more stable performance than traditional integrated rails. Matched with LNG pressure reducers, it controls gas supply steadily via ECU signals, achieving uniform atomization, smooth combustion and stable power output. It is a practical upgrade and replacement part for LNG passenger cars, commercial trucks and engineering machinery.
Product Introduction
Traditional integrated gas rails commonly have minor defects such as inaccurate injection, uneven gas supply and gradual aging after long use. These issues may cause engine jitter, slow acceleration and increased gas consumption, affecting vehicle running stability.
Our upgraded LNG single injector rail adopts a split injection structure and reliable solenoid core, with stable ECU signal response and consistent single-point injection performance. Optimized for LNG working characteristics, it operates steadily at 0.3-0.6Mpa working pressure, improving common stability problems of ordinary injection rails.

Product feature and application
Core Working Advantages
The independent single-nozzle structure avoids uneven gas supply between cylinders seen in integrated rails, effectively improving common issues like engine jitter, slow acceleration and high fuel consumption. It maintains stable injection accuracy under variable speed and load conditions, delivering consistent power output and better fuel economy.
The product features good anti-aging and anti-blocking performance, which reduces impurity accumulation in LNG fuel and lowers daily maintenance frequency. Stable long-term injection keeps the engine in good combustion state, helping control operating costs and improve vehicle stability.
Main Application Scenarios
It is suitable for LNG passenger cars, commercial trucks and engineering machinery, applicable for new vehicle assembly, gas system upgrades, faulty part replacement and fleet renovation. It works well with most mainstream LNG gas conversion kits for common working scenarios.
Product Details
The rail body adopts high-strength alloy material, with stable pressure resistance and vibration resistance for long-term engine operation. The matched solenoid core provides consistent and stable injection volume. Quality composite seals resist low-temperature aging and medium corrosion, maintaining reliable gas tightness in long-term use.
The optimized nozzle structure forms even fuel atomization to support sufficient combustion. The independent split design reduces mutual interference between nozzles. Standard reserved interfaces support plug-and-play installation, no complex modification required for easy replacement and daily maintenance.
