Answer:
🟠GVU stands for “gas valve unit.”
🟠GVT stands for “gas valve mechanism.”
[The design may be compact or a separate compartment next to the GE, GCU, or ME.]
Both devices regulate the gas supply pressure depending on engine load, ensuring a stable and accurate supply of low-pressure gas (typically 5-10 or 300 bar) to the gas supply valves.
Includes safety features: dual shut-off and bleed valves that isolate the gas flow during shutdowns or malfunctions. In hazardous situations (such as leaks), it automatically vents and purges the gas line with nitrogen to prevent explosions.
✈️ The device monitors pressure and temperature, integrating with the engine management system for smooth operation in gas mode.
