4TNE98T
Yanmar

The Yanmar 4TNE98T is a robust, turbocharged diesel engine engineered to deliver a powerful combination of high torque, fuel efficiency, and reliable performance for demanding industrial, agricultural, and construction applications. Built on Yanmar's proven 4TNE platform, the "T" designation signifies its advanced turbocharged configuration, offering enhanced power density and responsiveness to meet the rigorous demands of modern equipment.
| Feature | Specification / Description |
|---|---|
| Engine Model | Yanmar 4TNE98T |
| Configuration | In-line 4 Cylinder, 4-Stroke, Water-Cooled Diesel |
| Aspiration | Turbocharged & Intercooled (Key feature indicated by "T") |
| Fuel System | Direct Injection |
| Rated Power | High output within the series range (e.g., ~70-90 kW / ~94-121 HP) |
| Emissions Technology | Engineered for global compliance (e.g., EPA Tier 4 Final / EU Stage V equivalent) |
| Key Design | High torque output, Durable construction, Turbocharged performance |
The 4TNE98T is designed as a prime mover for medium to heavy-duty equipment requiring dependable power and high torque.
Agricultural Machinery: Ideal for powering mid-to-large tractors, combine harvesters, balers, and high-capacity irrigation pump sets where strong pulling power is essential.
Construction & Industrial Equipment: Provides reliable power for generator sets, industrial air compressors, large forklifts, compactors, and drilling equipment.
Material Handling: Well-suited for heavy-duty forklifts and terminal tractors operating in ports and logistics centers.
1. Advanced Turbocharged Performance
The integrated turbocharger and intercooler system is the core of this engine's advantage. It forces a greater mass of dense, cool air into the cylinders, dramatically improving combustion efficiency. This translates directly into higher power output, superior low-end and peak torque, and improved fuel economy under load compared to non-turbocharged models.
2. Durable and Reliable Direct Injection System
The engine utilizes a robust direct injection fuel system known for its reliability and efficiency. This system contributes to stable combustion, consistent performance, and overall operational durability in tough working environments.
3. Built for Longevity and Severe-Duty Cycles
Constructed with a high-strength cylinder block and reinforced internal components, the 4TNE98T is engineered to withstand continuous, high-load operation. This focus on durability ensures extended service life, maximizes equipment uptime, and contributes to a lower total cost of ownership.
