Key Components of Small Gasoline Engines

Gasoline engines consist of several essential components that work together to ensure their smooth operation. These components include:


We produce robust pistons that oscillate seamlessly within the cylinder. This movement is a result of our precision engineering, transforming the force of combustion into linear motion to drive the engine.


Our crankshafts are expertly crafted to convert the linear motion of the piston into rotational motion. This is a critical process in powering the machines or devices attached to our engines. Quality and durability are our top priorities when producing these essential components.

Ignition System

Our ignition systems, comprising key parts like spark plugs, ignition coil, and distributors, are designed for reliability and longevity. They ignite the fuel-air mixture at the precise moment, ensuring efficient combustion every time.


At BISON, our engines are fitted with high-quality intake and exhaust valves. These valves expertly regulate the flow of the fuel-air mixture and exhaust gases in and out of the cylinder, ensuring optimal engine performance.

Cooling System

Recognizing the importance of maintaining ideal operating temperatures, BISON incorporates advanced cooling systems in our small gasoline engines. These systems effectively prevent overheating, prolonging the life and enhancing the performance of our engines.


Cylinders provide the perfect combustion chamber for fuel burning, ensuring optimum power output and efficiency. We meticulously design and manufacture the cylinder, the core component of BISON gasoline engines.

Exhaust System

BISON's exhaust systems are designed to safely direct burned gases away from the engine while also reducing noise levels. Our commitment to environmental responsibility means we continually work to improve the efficiency and cleanliness of our exhaust systems.

We are a generator factory located in Taizhou City, Zhejiang Province. There are currently 2 factories with an annual output of more than one million units and more than 400 employees.

Quality control is essential to building a successful business that delivers products that meet or exceed customers’ expectations. It also forms the basis of an efficient business that minimizes waste and operates at high levels of productivity. So, each of our products, whether raw materials or finished products, will be inspected and tested one by one.

Absolutely! Outdoor power equipment including lawnmowers, chainsaws, leaf blowers, and trimmers frequently employ gasoline engines. These engines provide the mobility and power essential for effective operation in outdoor environments.
