Four-stroke engine is the most common internal combustion engine. They are used in a variety of different applications in multiple industries. BISON 4-stroke 168F engine provides power for a series of outdoor power equipment, including lawn mowers, generators, water pumps and tillers. Our four-stroke engines are the world leader in terms of output and quality.
High Stability: Made of nice quality cast iron and precision power transfer shaft, ensuring stable power transmission and low vibration
Energy saving and oil-saving: Adopts an innovative fuel system that burns gasoline completely, and the 4-stroke OHV mechanism provides fuel saving and high output
High quality: The pull wire has excellent abrasion resistance and high air filtration performance, reducing wear and prolonging the life of the engine
Low Noise: The low noise reduction design greatly reduces unpleasant noise, and ensures a reliable engine start without any kettle
Wide Range of Applications: With a maximum of 6.5 hp power, it is suitable for a variety of machines such as water pump, generator, high pressure washer, etc

Greater torque: 4-stroke engines always produce extra torque at low speeds than 2-stroke engines.
Higher fuel efficiency: 4-stroke engines have higher fuel efficiency than 2-stroke engines. At the same time, less waste gas pollution is produced.
No additional oil is required: only the moving parts require intermediate lubrication.
Complex design: The four-stroke engine has a complex mechanism, which increases the probability of failure.
Low power: the power is transmitted once every 4 strokes, and the power is small.
Intake: In the first stage, since the intake valve remains open and the piston is downward, air can enter the cylinder.
Compression: When the piston reaches bottom dead center and starts to move to the top, the intake valve closes, thereby compressing the air in the cylinder and significantly increasing the temperature.
Combustion: Shortly before reaching the top dead center, the fuel injector injects fuel into the combustion chamber, and the fuel ignites immediately after it comes in contact with the hot air.
Exhaust: After being ignited, the piston moves down, and due to inertia, it will return to the top dead center, thereby expelling the combustion gas and starting the cycle again.
