| Feature | Specification |
|---|---|
| Engine Model | Yanmar 3TNV80F |
| Configuration | In-line 3 Cylinder, 4-Stroke, Water-Cooled Diesel |
| Displacement | Approximately 1.3 - 1.5 Liters |
| Aspiration | Turbocharged & Intercooled |
| Fuel System | High-Pressure Common Rail with Electronic Control |
| Governor Type | Full-Authority Electronic (Indicated by "F" suffix) |
| Emissions Compliance | EPA Tier 4 Final / EU Stage V (Platform Standard) |
The 3TNV80F is engineered as a versatile and dependable prime mover for equipment requiring precise power management and reliable performance.
Compact Construction Machinery: An ideal power source for mini excavators, compact wheel loaders, skid-steer loaders, and light towers.
Agricultural & Grounds Care Equipment: Provides efficient power for compact tractors, utility vehicles, and large commercial mowers.
Power Generation: Serves as a reliable driver for generator sets, where its electronic governing ensures stable frequency and voltage output.
Industrial Applications: Powers pumps, compressors, and other industrial machinery requiring consistent, controlled power.
1. Advanced High-Pressure Common Rail Fuel System
The engine features a state-of-the-art high-pressure common rail fuel system. This technology enables ultra-precise, multiple fuel injections per combustion cycle, optimizing efficiency for superior fuel economy, significantly reduced engine noise, lower emissions, and responsive power delivery.
2. Full-Authority Electronic Control & Turbocharging
The full-authority electronic control system is the intelligence behind the engine's performance. It provides precise management of fuel, air, and aftertreatment systems. Combined with efficient turbocharging and intercooling, this ensures optimal combustion across all operating conditions, delivering strong low-end torque and high power density.
3. Integrated Emissions Control for Global Compliance
Engineered to meet the strictest global standards, the 3TNV80F utilizes a fully integrated aftertreatment system. This typically includes advanced components like a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR), ensuring clean operation and regulatory compliance without sacrificing performance or durability.
4. Durable Design for Maximum Uptime
Built with a high-strength cylinder block and premium components designed for severe-duty cycles, the engine ensures long service life and reliability. Its robust construction supports extended service intervals and easy maintenance, contributing directly to lower operating costs and higher equipment availability.
