Additionally, its long-term reliability makes it a suitable choice for long-term operations, as well as for standby applications.

The working principle of the QJ8/2 is fairly straightforward. The process begins with the fuel being pumped into the fuel system, where it is then distributed to the fuel injectors. The fuel is injected into the combustion chamber, where air is also added, forming a combustible mixture that is ignited by the spark plug, resulting in combustion. The pistons move downwards due to the combustion, creating power, which is transferred to the drive shaft. The drive shaft then transfers the power to the machine that is being powered by the engine.

The QJ8/2 is designed to create maximum efficiency from the power produced. It achieves this by utilizing a high-performance fuel-injection system, which ensures a consistent mix of air and fuel, which in turn allows for complete combustion. The advanced combustion process has been designed to minimize emissions, resulting in a cleaner and more efficient combustion cycle. This improved combustion also allows the engine to operate more efficiently, thereby reducing fuel consumption.

Overall, the QJ8/2 is a dependable and efficient engine choice for a wide range of applications. With its combination of low speed, heavy-duty components, and advanced control systems, the QJ8/2 is an excellent choice for a variety of machines, such as power generation, diesel-electric locomotives, construction and agricultural machinery. The engine is also highly reliable, making it a suitable choice for long-term operations, as well as for standby applications. Thanks to its efficient combustion cycle, the QJ8/2 is also capable of reducing fuel consumption and emissions, making it a sensible choice for both industrial and agricultural applications.
