Engine Model: CAT C18
Manufacturer: Caterpillar
Engine Type: Diesel - fueled, four - stroke, turbocharged (in most configurations) and aftercooled engine, designed for a wide range of industrial applications such as heavy - duty construction equipment, power generation, and marine propulsion.
2. Performance Specifications
Power Output
Rated Power: The rated power output of the CAT C18 engine can range from approximately 447 kW (600 hp) to 708 kW (950 hp), depending on the specific configuration, application, and operating conditions such as altitude and ambient temperature.
Maximum Power: In some applications with short - term power demands, the engine can provide a higher peak power output, usually through advanced turbocharging and fuel injection strategies.
Speed
Rated RPM: Typically, the rated speed is around 1800 - 2100 revolutions per minute (RPM). This speed range is optimized for efficient power delivery and fuel economy in industrial applications.
3. Mechanical Specifications
Configuration
Cylinder Arrangement: V - 18 configuration (18 cylinders arranged in a V - shape). This design provides a compact footprint for the high - power output and relatively smooth operation due to its inherent balance characteristics.
Bore and Stroke: The bore diameter is usually around 145 mm and the stroke length around 183 mm. These dimensions directly influence the engine's displacement and combustion characteristics.
Displacement: The displacement of the CAT C18 engine is approximately 34.5 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 1900 - 2200 kg. The weight can vary depending on additional components such as the turbocharger, aftercooler, and other accessories.
Wet Weight: With all fluids (coolant, fuel, and oil) filled to the recommended levels, the weight can increase to around 2200 - 2500 kg.
Dimensions
Length: Approximately 1700 - 1900 mm.
Width: Around 1100 - 1300 mm (including external components like manifolds and turbochargers).
Height: Roughly 1400 - 1600 mm. These dimensions are approximate and can vary based on the specific installation requirements and additional equipment attached.
