Engine Model: D902
Manufacturer: Kubota
Type: Four – stroke, diesel – fueled, vertical – cylinder engine. Commonly used in small – to – medium – sized agricultural and construction equipment, generators, and other machinery.
2. Performance Specifications
Power Output
Rated Power: Typically ranges from about 16.5 to 24.8 horsepower (12.3 – 18.5 kW). The actual power output can vary depending on factors such as engine speed and application requirements.
Torque: The engine provides a significant amount of torque, which is essential for applications that require pulling or pushing power. Peak torque usually occurs at a lower – mid range of engine speeds.
Speed
Rated RPM (Revolutions per Minute): Usually in the range of 2800 – 3600 RPM. This speed range is designed to balance power output, fuel efficiency, and the operational requirements of the equipment it powers.
3. Mechanical Specifications
Cylinder Configuration
Number of Cylinders: 3 – cylinder vertical arrangement. This configuration provides a relatively smooth operation compared to single – cylinder engines and is more compact than larger multi – cylinder engines.
Bore and Stroke: The bore (cylinder diameter) is approximately 90 mm, and the stroke (distance the piston travels) is around 78 mm. These dimensions are crucial in determining the engine's displacement and combustion characteristics.
Displacement: The total displacement of the engine is about 1.437 liters. It's calculated using the formula: Displacement = (π/4) × (bore)² × stroke × number of cylinders.
Engine Weight
Dry Weight: The dry weight (without coolant, fuel, and oil) is usually around 170 – 190 كجم. The weight can vary depending on additional components such as the fuel injection system and alternator.
Wet Weight: With all fluids (coolant, fuel, and oil) filled to the recommended levels, the weight is approximately 190 – 210 كجم.
Dimensions
Length: Roughly 600 – 700 mm.
Width: Around 400 – 500 mm (including external components like the fuel tank and air cleaner).
Height: Approximately 600 – 700 mm. These dimensions are approximate and can vary based on the specific installation requirements and additional equipment attached.
