Injector for Hydrogen Fuel Cell Vehicles


This injector controls the flow volume of decompressed hydrogen gas from the regulator based on electrical signals from the ECU in order to deliver the required hydrogen to the fuel cells.
They are built into an injector ejector unit comprised of low-pressure system components.

The Keihin Advantage

Adopts the same basic structure used for natural gas vehicles
Based on gas fuel valve technology tested in injectors for natural gas vehicles, with improved durability, low-temperature operability, and hermetic performance.

Seal materials and bearings designed to withstand the hydrogen environment
The seal materials were developed to ensure airtightness, using special bearing specifications to maintain durability in a non-lubricated environment.

Customer Benefits

・Reliable flow control contributes to more stable power generation from the fuel cells.
