2. Performance Specifications
Power Output
Rated Power: The rated power of the Cummins ISF3.8 engine typically ranges from around 95 – 125 kW (127 – 168 hp), depending on the specific configuration and application. The engine offers different power ratings to suit different machinery requirements.
Maximum Power: In certain conditions such as short – term overloads, the engine can produce a slightly higher power output. However, continuous operation at maximum power is not recommended to avoid engine damage and ensure longevity.
Speed
Rated RPM: The engine usually has a rated speed of around 2600 – 3200 revolutions per minute (RPM). This speed range is designed to provide a balance between power output and fuel efficiency for different machinery applications.
3. Mechanical Specifications
Configuration
Cylinder Arrangement: In – line 4 – cylinder configuration. This arrangement provides a relatively compact design and good balance, reducing vibrations during engine operation.
Bore and Stroke: The bore diameter is approximately 102 mm and the stroke length around 118 mm. These dimensions directly affect the engine's displacement and combustion characteristics.
Displacement: The displacement of the Cummins ISF3.8 engine is about 3.76 liters. It's calculated using the formula .
Weight
Dry Weight: The dry weight of the engine (without coolant, fuel, and oil) is around 320 – 360 kg. The weight can vary depending on additional components like the turbocharger (if equipped), alternator, and other accessories.
Wet Weight: With all fluids (coolant, fuel, and oil) filled to the recommended levels, the weight can increase to approximately 360 – 400 kg.
Dimensions
Length: Roughly 800 – 900 mm.
Width: Around 600 – 700 mm (including external components such as manifolds).
Height: Approximately 700 – 800 mm. These dimensions are approximate and can vary based on the specific installation requirements and additional equipment attached.
