In addition, we also provide water-cooled diesel engines. For our single-cylinder diesel engine built with direct injection technology, it can be started quickly and easily with just one pull. The two-cylinder diesel engine is easy to install, has low fuel consumption, and achieves maximum combustion efficiency. Today, small diesel engines are widely used in generator sets, pressure washers, and some agricultural and construction applications, or as small stationary generators (such as generators on yachts).

There are currently two types of diesel engines on the market. Two-stroke diesel engine completes the power cycle by two strokes of the piston when the crankshaft rotates one revolution, while the four-stroke diesel engine completes the cycle by rotating the crankshaft in four separate strokes. Diesel engines can provide better running performance and higher fuel economy, making them more and more popular among end users. BISON provides diesel engines for all small machinery.

BISON has been producing high-performance diesel engines for many years. Professionals in each of our departments, basic research, development, production and after-sales support, are looking for processes to maximize customer value. We promise to provide diesel engines that meet your requirements under excellent quality control.

diesel engine applications

Diesel engine parts


After the air is compressed, fuel is injected into the cylinder, and then the diesel is ignited and exploded. This explosion moves the piston, generating power for the engine.


The piston is a device that slides up and down in the cylinder. Their job is to slide in and out, connected to the crankshaft, to compress the air injected into the cylinder. The air entering the cylinder is compressed to 14-25th of its original volume.


The job of the camshaft is to adjust when to let fuel enter and when to exhaust gas.

Fuel injector

The purpose of the fuel injector is to atomize the fuel. This means turning the liquid fuel into a mist, which greatly increases its surface area. This allows the fuel to burn faster, thereby providing more driving force for the piston.


The crankshaft is the most important component of the engine because it connects the parts together and enables the engine to generate power. Its purpose is to convert the linear motion of the piston into a rotary motion. One end of the crankshaft is connected to the camshaft. The other end is connected to the flywheel, which regulates the power of the engine.

BISON provides a large number of original, aftermarket and remanufactured parts for various popular diesel engines to help you handle any diesel generator maintenance work. We have our own diesel engine production workshop, follow strict manufacturing processes, and continuously control the quality of our products.
