The 3TNV70 is a versatile power source built for compact machinery that requires dependable, continuous-duty performance. Its primary applications include:
Compact Agricultural Machinery: Ideal for powering walk-behind tractors, small riding mowers, tillers, sprayers, and irrigation pumps.
Light Construction & Industrial Equipment: Provides reliable power for small generators (10-15 kVA), welders, air compressors, and light material handling equipment.
Mobile & Auxiliary Power: Well-suited for mobile cleaning machines, turf equipment, and as an auxiliary power unit in various vocational vehicles.
1. Advanced Combustion and Fuel System
The engine utilizes an efficient direct injection fuel system combined with an optimally designed combustion chamber. This technology ensures precise fuel delivery and complete combustion, resulting in superior fuel economy, low emissions compliance (meeting stringent EPA Tier 4 Final/EU Stage V standards without complex after-treatment), and stable power output.
2. Compact and Lightweight Design
Engineered with a compact footprint and low weight, the 3TNV70 offers excellent power-to-size and power-to-weight ratios. This design philosophy allows for easy integration into space-constrained equipment chassis without sacrificing performance or durability.
3. Low Noise and Vibration Operation
Through meticulous engineering, including a balanced crankshaft and refined engine structure, the 3TNV70 operates with remarkably low noise and vibration levels. This enhances operator comfort and allows the equipment to be used in noise-sensitive environments.
