Fuel Injection System Repairs & Overhaul

Maximizing Engine Efficiency Through Precision Fuel Injection Maintenance 

Proper maintenance of 2-stroke diesel engine fuel injection systems is critical for engine efficiency, performance, and compliance with IMO emission regulations. Faulty components such as fuel pumps, injectors, and valves can cause poor atomization, leakage, and performance loss.

KIMI provides expert repair, overhaul, and fuel valve reconditioning for main and auxiliary engines from OEMs including MAN B&W, Sulzer, and Mitsubishi. Services are performed in-house or onboard, fully compliant with OEM and class standards.

Our capabilities include barrel and plunger remanufacturing, precision injector reconditioning, and timing adjustments, ensuring optimal fuel delivery, reduced emissions, and extended component life.

FAQs

Yes. KIMI has a dedicated in-house department for 2-stroke fuel injection systems, delivering specialized overhaul, repair, and remanufacturing services in full compliance with OEM and class requirements.

KIMI provides complete services for fuel pumps, injectors, fuel valves, barrels & plungers, non-return valves, and spindle guides, restoring them to zero-hour condition and ensuring optimal engine performance.

KIMI provides advanced in-house remanufacturing solutions for key fuel injection components, including barrel & plungers (since 1998), non-return valves, and spindle guides.

Through our remanufacturing solutions, components are restored to “zero-hour” condition, effectively resetting their service life and delivering performance equivalent to new OEM parts—while achieving significant cost savings.

All reconditioned components are tested using in-house test bench equipment, including opening pressure testing of fuel valves.

This ensures:

• Correct opening pressure at nominal values
• Proper sealing and tightness
• Reliable atomization and performance

Each component is verified after reconditioning to meet OEM specifications, guaranteeing optimal operation and compliance with performance standards.
