Auxiliary Engine (Generator Set) · Auxiliary Engines
The Perkins 1206D-E70TA also branded as C7.1 is a marine auxiliary engine. Auxiliary engines are installed in the engine room or dedicated machinery spaces to provide power for shipboard services, most commonly by driving an electrical generator but also, in some installations, pumps, hydraulic equipment or other auxiliaries. The engine operates independently of the main propulsion engine and is expected to accept changing service loads while maintaining reliable speed and support-system conditions. Compared with neighbouring auxiliary-engine entries, this unit is distinguished by its exact manufacturer and model designation and the stated rating where provided. Operational reliability depends on sound fuel injection, lubrication, cooling, starting, governor or electronic speed control and correct integration with the driven machine. For cylinder dimensions, rotational speed, pressures, clearances, temperatures, wear limits and setting values, refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Check starting reliability, load acceptance, speed stability and the engine's ability to carry its assigned electrical or mechanical load. Trend exhaust temperatures, oil pressure, cooling temperatures and abnormal vibration and compare cylinders or operating points for imbalance. Inspect fuel, oil, cooling-water and exhaust systems for leakage and verify filters, coolers, pumps and ventilation are in serviceable condition. For generator sets, verify governor response, load sharing, generator protection, emergency shutdowns and automatic-start functions where fitted. Inspect foundations, flexible mounts or couplings and the interface with the alternator or driven machine. For cylinder dimensions, rotational speed, pressures, clearances, temperatures, wear limits and setting values, refer to the manufacturer documentation for the exact figure.
Keep fuel and lubricating-oil filters, air-filter elements where fitted, injector-related spares, seals and gaskets, pump service kits and starting-system components on board. For generator duties, carry selected governor or speed-control components, sensors, relays and common electrical interface spares according to the installed control system. The final spare inventory should follow manufacturer recommendations, class requirements and the number of redundant generator or auxiliary sets available.
