4TNV84T
Yanmar

The Yanmar 4TNV84T is a high-performance, water-cooled diesel engine engineered to deliver an exceptional balance of power density, fuel efficiency, and reliable operation in a compact package. Featuring advanced turbocharging technology, this engine is designed to meet the rigorous demands of modern compact industrial, construction, and agricultural equipment while complying with stringent global emission standards.
| Feature | Specification / Description |
|---|---|
| Engine Model | Yanmar 4TNV84T |
| Configuration | In-line 4 Cylinder, 4-Stroke, Water-Cooled Diesel |
| Aspiration | Turbocharged & Intercooled (Key feature) |
| Fuel System | High-Pressure Common Rail with Electronic Control |
| Emissions Compliance | Engineered for EPA Tier 4 Final / EU Stage V standards |
| Key Design | Compact footprint, High power-to-weight ratio, Low NVH |
The 4TNV84T is engineered as a versatile prime mover for medium-duty compact equipment requiring responsive power and high reliability.
Compact Construction Machinery: An ideal power source for compact track loaders, mini excavators, aerial work platforms, and light compaction equipment.
Agricultural & Industrial Equipment: Provides efficient power for compact utility tractors, turf equipment, generators, and industrial pumps.
1. Advanced Turbocharged Performance
The integrated turbocharger and intercooler system forces a dense charge of air into the cylinders. This technology is central to achieving high power density and strong low-end torque from a compact design, providing the responsive performance needed for equipment with sudden load changes.
2. High-Precision Common Rail Fuel System
The engine utilizes a high-pressure common rail fuel system managed by an intelligent Electronic Control Module (ECM). This ensures ultra-precise fuel injection timing and quantity, optimizing combustion for superior fuel economy, reduced emissions, and smooth power delivery.
3. Integrated Emissions Control System
Designed to meet the world's strictest regulations, the engine incorporates a fully integrated aftertreatment system. This typically includes a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) technology, ensuring clean and compliant operation without sacrificing performance or durability.
