● The engine is air cooled and water cooled, with a dual cooling effect superior to ordinary water cooling, lower heat load, and better durability;

● Adopt low speed and high torque intake ports to improve the power output of the engine at low rotational speeds, so that the engine truly meets the operating conditions of tricycles;

● Special water cooled piston, which increases the head volume, increases the engine compression ratio, and improves the engine's power output; Adding micro arc oxidation treatment to the head to improve the service life of the piston;

● The clutch adopts 7 widened clutch plates, with stronger bearing capacity;

The right crank adopts a unique oil pan structure to effectively deposit impurities, making the oil entering the crankshaft needle and piston cleaner and making the crankshaft and piston more durable;

● The oil between the crankshaft big end, cylinder block and piston is filtered twice to improve the cleanliness of the oil, reduce wear between the friction pairs, and improve the service life;

● Special right large cover for water cooling, with a unique washable reusable fine filter structure and steel filter screen, making cleaning more convenient and engine oil cleaner;

The crankshaft large end needle roller is made of imported materials, which enhances the strength of the needle roller and extends its service life;

● Water cooled unique alloy cast iron material cylinder liner, with higher wear resistance; The cylinder block adopts platform reticulation technology, making the formation of oil film easier. Improved lubrication between the cylinder block, piston, and piston ring, improving reliability;

● The use of special steel oil pump gears improves the high temperature and oil resistance of the oil pump gears, making the engine lubrication performance more stable;

● Adopt a pressure reducing valve cam, making foot starting more convenient and effectively protecting the overrunning clutch.
