Fixed-Speed YANMAR Diesels for Generator Sets
The YANMAR generator-use engines are fixed-speed industrial diesels built for generator sets, from the 11.8 hp 3TNM74F-NGGE to the 68.4 hp 4TNV98CT-GGE. Most run at 1800 rpm; the 3TNM74F-NH6GE runs at 3600 rpm. All are EPA Final Tier 4 except the 4TNV98T-ZGGM, which is certified to EPA Marine Tier 3.
Now even more reliable. The Final Tier 4 line builds on the legendary reliability of the YANMAR TNV line, with a focus on vibration reduction and high-strength materials.
Final Tier 4 compliant. Building off the proven TNV design, YANMAR improved the combustion chamber and increased the displacement and compression ratios to meet the strict NTE and NRTC test requirements.
Better fuel efficiency, fewer emissions. A refined combustion process gives more precise fuel delivery and control, for reduced emissions and increased fuel economy.
The table on the Specs tab gives YANMAR America’s gross power for each engine. For generator sizing, each spec sheet on the Downloads tab gives the engine’s own ratings for its generator duty.
