Products Description
YC112 CNG/LPG Injector Rail for Sequential Gas Injection
YC112 is a CNG/LPG injector rail for sequential gas injection conversion systems. The rail assembly includes solenoid-operated injectors, valve nozzles and a rail body. The selected injector configuration should match the engine-cylinder quantity and the intended CNG or LPG system requirement.
This product category can be discussed for vehicle conversion projects using matched ECU kits, pressure reducers, wiring harnesses and related gas-system components. Final compatibility must be confirmed according to the vehicle engine, original petrol injection arrangement and selected system configuration.

Frequently Asked Questions
What information is needed to select a YC112 injector rail?
Please provide the vehicle model, engine-cylinder quantity, intended fuel, original petrol injection configuration, required ECU kit and related reducer or wiring requirements. These details help identify the relevant injector-rail configuration for discussion.
What is the difference between the LPG and CNG versions?
The listed LPG version uses 2Ω resistance, while the listed CNG version uses 3Ω resistance. The suitable version should be confirmed with the selected fuel application and ECU configuration.
Can YC112 be discussed with a matched ECU kit and pressure reducer?
Yes. The injector rail, ECU kit, pressure reducer, wiring harness and related components should be considered together for the intended CNG/LPG sequential conversion-system configuration.
