FIVA Overhaul & Calibration for ME Engines
Plan your FIVA overhaul and calibration with INJEGOV. Expert multiway valve service for electronically controlled ME engines, reducing fuel use and downtime
What Is a FIVA Valve?
FIVA (Fuel Injection & Valve Actuation) is a high-precision multiway hydraulic servo valve mounted on each cylinder of electronically controlled ME-type engines.
Using high-pressure engine oil as the control medium, the FIVA valve:
- Meters and times the fuel injection event.
- Opens and closes the exhaust valve according to the engine’s electronic control system.
- Reacts in milliseconds to the engine control commands over millions of operating cycles.
Technical documentation describes these multiway valves (FIVA, ELFI, ELVA) as key components for fuel injection and/or exhaust valve opening in ME engines, emphasizing their precision nature and direct impact on performance and operational efficiency.
Because a single valve controls both fuel and exhaust events for one cylinder, any deviation in its hydraulic performance or calibration affects the entire engine balance.
FIVA Valve Impact on Performance, Emissions & Reliability
Optimum control of fuel injection and exhaust outlet is a precondition for low emissions and minimum operating costs.Well-maintained and correctly calibrated FIVA valves deliver:
- Stable low-load operation.
- Reduced specific fuel oil consumption.
- Lower NOx and particulate emissions.
- Smooth starting and fast load response.
- Protection of critical components (cylinder cover, pistons, exhaust valves).
When Is a FIVA Valve Due for Overhaul?
- Planned overhaul every ~32,000 running hours (≈5 years).
- Replacement of the complete valve after ~64,000 running hours (≈10 years) when wear of the main spool and housing reaches the design limits.
These intervals assume normal operating conditions and correct oil cleanliness. Running significantly beyond them increases the risk of:
- Spontaneous valve failure.
- Extended slow steaming or de-rating of the engine.
- In extreme cases, over-pressure in the cylinder and loss of manoeuvrability.

What FIVA Overhaul Includes at INJEGOV
New Generation Test Bench at INJEGOV
INJEGOV has recently invested in a new state-of-the-art FIVA test bench designed to replicate real ME engine operating conditions with even higher accuracy. The system allows precise measurement of leakage, response time and flow characteristics under controlled pressure profiles, supporting more reliable zero-point calibration and detailed diagnostics. This upgrade shortens turnaround time, improves repeatability of results and ensures every valve returns to service fully verified against demanding performance standards.
