Rural Cargo Hauling Tricycle

The power system is the core of this upgrade. The rural cargo hauling tricycle offers two displacement options of 200cc and 250cc water-cooled gasoline engines, both adopting a single-cylinder four-stroke overhead valve structure, matched with a front-mounted large-size aluminum radiator and a forced circulation water pump to form a closed-loop water-cooling system. Compared with air-cooled models of the same level, the working temperature of the engine cylinder head can be reduced by more than 25℃. When driving continuously under full load in an environment above 40℃, there is no obvious attenuation of power output, completely solving the overheating problem under long-distance climbing and high-frequency heavy-duty conditions. The 250cc version delivers a rated output power of 9.2kW at 7500rpm and a peak torque of 15.2N·m at 5500rpm. Matched with a 5-speed cyclic transmission mechanism, it provides sufficient torque amplification in low gears, with a maximum climbing angle of 22° under full load, and can stably run on hilly roads and rural dirt roads. The core engine components adopt alloy wear-resistant cylinder liners and forged crankshafts. Combined with the constant-temperature working environment of water cooling, the major overhaul cycle of the whole engine is extended to more than 50,000 kilometers, and the service life is increased by 30% compared with air-cooled models. The fuel supply adopts a vacuum diaphragm carburetor with high atomization efficiency and excellent fuel economy. The comprehensive fuel consumption is about 3.0L per 100 kilometers. Matched with a 14L large-capacity fuel tank, the cruising range on a full tank exceeds 400 kilometers, reducing the frequency of refueling on the way and meeting the demand for long-distance transportation between towns and villages.
