These diesel engine assemblies are designed to provide reliable power for a range of applications. They are commonly used in agricultural machinery, construction equipment, generators, and other industrial or mobile power - requiring systems.
2. Engine Configuration
Cylinder Arrangement:
The engine is typically a four - cylinder configuration. This arrangement provides a balance between power output and smooth operation. The four - cylinder in - line design helps in distributing the power strokes evenly, reducing vibration and ensuring a more consistent torque output.
Bore and Stroke:
The bore (cylinder diameter) and stroke (piston travel distance) are important dimensions that determine the engine's displacement and performance characteristics. For these engines, the bore might be in the range of 84 - 86 mm and the stroke around 90 - 92 mm. These dimensions result in an effective displacement that influences the power and torque capabilities of the engine.
3. Power and Performance
Rated Power:
The rated power of the engine varies depending on the specific model and application requirements. Generally, it can range from around 18 - 25 kW (kilowatts). The power output is achieved at a specific rotational speed, which is an important factor for matching the engine to the load it will drive.
Torque Output:
The torque output is related to the power and rotational speed through the formula . At the rated speed, the engine provides a significant amount of torque to drive various loads such as pumps, compressors, or mechanical drives. The torque curve of the engine is designed to offer good low - speed torque for better starting and acceleration characteristics.
Speed Range:
The operating speed range of the engine usually extends from an idle speed of around 600 - 800 revolutions per minute (rpm) to a maximum rated speed of around 3000 - 3200 rpm. This range allows the engine to operate effectively in different applications, from slow - moving equipment to those requiring higher speeds for power generation.
