The SURTEC NTDE186FA is the heavy-duty anchor among SURTEC's compact diesel engines: 9.0hp — 6.6kW at 3600r/min — from a 418cc single-cylinder, horizontal, four-stroke, air-cooled block with direct injection, and a 19.5:1 compression ratio working behind every pull of the torque curve. Powerful, steady torque output is the headline — the kind that keeps a loaded tiller climbing and a pump holding pressure when the work gets heavy. It is built for the applications where a smaller engine spends its life at full throttle — generator sets, pump sets and construction machinery that need steady pulling force hour after hour.

Combustion is where the NTDE186FA makes its case. The direct-injection system atomizes fuel finely, producing greater torque output, lower emissions and reduced fuel use — holding consumption at or below 280 g/kWh even under sustained load. BOSCH-style fuel injection keeps the burn smooth and consistent from cold start to the end of the shift, and the air-cooled configuration holds thermal stability through prolonged operation, no radiator to maintain and no coolant to leak.

Mechanically, the engine is built to outlast the machines it powers. A 42CrMo forged-steel crankshaft carries continuous high loads, while reinforced nitrided transmission gears minimize wear and vibration for smooth, balanced running. Starting stays simple — a manual system with quick ignition response — and the 5.5L fuel tank with a 1.65L oil tank keeps the package self-contained and easy to spec into new equipment.

Installation was kept as practical as the design is rugged. The compact structure fits tight engine bays, simplifies mounting and reduces maintenance effort in the field; air-filter care is a regular check with cleaning or replacement every 50 hours, and SURTEC tests the engine to run reliably from -5°C up to 45°C across varied terrains and climates. Agricultural machinery, construction tools and transport equipment are its natural homes, with output shafts, colors and specifications available for OEM customization.

For machinery factories, OEM buyers and spare-parts dealers shopping among high power engines, the NTDE186FA is the unit that carries the heavy end of the range: dependable torque, proven components and wholesale-ready supply from a manufacturer that keeps comprehensive spare-parts inventory for every engine it builds. As an engines supplier trusted across Latin America, Africa, Eastern Europe and Southeast Asia, SURTEC delivers the NTDE186FA at competitive pricing — ready to power the next generation of your machines.
