Main Engine 4-Stroke · Main Engines (4-Stroke)
This equipment category includes marine propulsion engines. Caterpillar's BCPXN18.1EN2 is a 6-cylinder, 4-stroke turbocharged engine designed for variable-pitch and electrically coupled propellers. Introduced in 2011, it operates under EPA Category 1 regulations with a rated power of 533 kW at 2100 rpm. Common failures include issues like poor combustion due to injector wear or fuel contamination, lubricating-oil pressure problems, cooling-system deterioration, valve-train faults, and fuel-system leakage. To ensure optimal performance, spare parts such as fuel filters, lubricating oil filters, injectors, and starting system components should be readily available onboard. Regular service checks focus on running records, visual inspections for leaks, and planned maintenance of key components to prevent potential issues.
Every value below comes from the manufacturer datasheet or class-society record on file for this model.

What our service work and the manufacturer documentation say about keeping this model running.
Review running records for exhaust-temperature spread, lubricating-oil pressure, cooling temperatures, starting behaviour, vibration and abnormal consumption trends. Inspect for fuel, lubricating-oil, cooling-water and exhaust leaks and check the condition of flexible connections, mounts, foundations and coupling or gearbox interfaces. Examine filters, coolers, pumps, valve gear, injectors and accessible combustion components in accordance with the planned-maintenance system. Check crankcase condition, oil analysis and any available bearing or vibration monitoring for developing wear. A surveyor should verify alarms, shutdowns, overspeed protection, emergency stopping arrangements and guarding of moving or hot parts as applicable to the installation. For cylinder dimensions, rotational speed, pressures, clearances, temperatures, wear limits and setting values, refer to the manufacturer documentation for the exact figure.
Carry fuel-filter and lubricating-oil-filter elements, approved seals and gaskets, injector service or replacement components, valve-train wear parts appropriate to the engine, and service parts for essential pumps. Critical installations should also hold selected sensors, relays or control modules, starting-system components, belts or flexible elements where fitted, and manufacturer-recommended bearing or cylinder-head service items. The exact onboard spare scale should follow the manufacturer, class requirements, engine redundancy and the vessel's trading pattern.
