Engine Model: SAA4D95LE - 3
Application: Specifically designed for use in Komatsu PC130 - 7 and PC110 - 7 excavators.
Manufacturer: Komatsu (associated with the excavator brand)
2. Performance Specifications
Power Output
Rated Power: The rated power of this engine usually ranges from around 66 - 75 kW (89 - 101 horsepower). This power output is calibrated to provide the necessary force for the excavator's digging, lifting, and other operational functions.
Maximum Power: In situations such as heavy - duty digging through tough materials, the engine can potentially provide a slightly higher output for short - term operations.
Speed
Rated RPM: The engine's rated speed is typically around 2000 - 2200 revolutions per minute (RPM). This speed range is optimized to deliver the right amount of torque for the excavator's hydraulic systems and other operational requirements.
3. Mechanical Specifications
Configuration
Cylinder Arrangement: In - line 4 - cylinder configuration. This layout provides good balance and smooth operation, reducing vibrations and noise during the engine's operation.
Bore and Stroke: The bore diameter is usually around 95 mm and the stroke length around 115 mm. These dimensions play a crucial role in determining the engine's displacement and combustion characteristics.
Displacement: The displacement of the SAA4D95LE - 3 engine is approximately 3.26 liters. Calculated using the formula V = π/4 × (bore)²× stroke × number of cylinders.
Weight
Dry Weight: The dry weight of the engine (without coolant, fuel, and oil) is approximately 380 - 420 kg. The actual weight may vary depending on additional components or accessories.
Wet Weight: With all fluids (coolant, fuel, and oil) filled to the recommended levels, the weight can increase to around 420 - 460 kg.
Dimensions
Length: Approximately 800 - 900 mm.
Width: Around 600 - 700 mm (including external components like manifolds).
Height: Roughly 700 - 800 mm. These dimensions are approximate and can vary based on the specific installation requirements and additional equipment attached.
