Logotipo de máquinas Tonkee
Engine Model: 3056 and 3056E
Manufacturer: Caterpillar
Engine Type: Four – stroke, turbocharged (in some configurations), diesel – fueled engine. It's used in a variety of machinery applications such as construction equipment, agricultural machinery, and generators.
2. Performance Specifications
Power Output
Rated Power: The rated power of the CAT 3056 engine typically ranges from around 105 – 134 kW (141 – 180 hp), depending on the specific configuration and application. The 3056E model might have different power settings optimized for better fuel efficiency and emissions control.
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 1800 – 2200 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 6 – cylinder configuration. This arrangement provides good balance and smooth operation, reducing vibrations during engine running.
Bore and Stroke: The bore diameter is approximately 102 mm and the stroke length around 120 mm. These dimensions directly affect the engine's displacement and combustion characteristics.
Displacement: The displacement of the CAT 3056 engine is about 5.9 liters. It's calculated using the formula .
Weight
Dry Weight: The dry weight of the engine (without coolant, fuel, and oil) is around 500 – 600 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 550 – 650 kg.
Dimensions
Length: Roughly 1000 – 1100 mm.
Width: Around 700 – 800 mm (including external components such as manifolds).
Height: Approximately 900 – 1000 mm. These dimensions are approximate and can vary based on the specific installation requirements and additional equipment attached.
