The 186F Air-Cooled Diesel Engine is a single-cylinder, 4-stroke, direct-injection diesel engine designed for agricultural, industrial, and power generation applications. With a rated power of 6.5kW (9HP) and maximum output of 7kW (10HP) at 3600RPM, it is one of the most popular compact diesel engines for tillers, water pumps, and generators worldwide.
Engineered for reliability and fuel economy, the 186F features a forced air cooling system that eliminates water-related maintenance issues, a direct injection combustion chamber for lower fuel consumption, and a rugged cast iron construction for extended durability. The engine supports both recoil start and electric start, offering flexibility for different operating environments.
Direct Injection Combustion System — Delivers superior fuel efficiency (≤280g/kW·h) and easy cold starting
Forced Air Cooling — No radiator, water pump, or antifreeze needed; maintenance-free cooling system
Cast Iron Cylinder Block & Forged Crankshaft — Built for long service life under heavy-duty conditions
Dual Starting System — Recoil start standard; 12V electric start optional for push-button convenience
Low Noise & Low Emission — Equipped with high-efficiency muffler and optimized injection timing
Compact Horizontal Shaft Design — Universal mounting dimensions compatible with most 9-12HP equipment
5L Large Fuel Tank — Extended operation time, fewer refueling interruptions
