Auxiliary Engine (Generator Set) · Auxiliary Engines
Series 1163 G-16cyl by MTU Onsite Energy is a sixteen-cylinder mechanical diesel engine listed in the supplied record at 4640 kW, 230 mm bore and 1300 rpm for MGO operation. In marine service an engine of this type can be installed as an auxiliary power source or generator prime mover, with fuel, lube-oil, cooling-water, starting-air or starting-electric and exhaust systems integrated around the engine. Its reliability depends on balanced combustion, clean fuel and lubricating oil, adequate cooling and correct valve and injection condition across all cylinders. The engine should be treated as a complete system: turbocharging, charge-air cooling, governing, protection and generator coupling can all produce symptoms that appear to be internal engine faults. Neighboring Series 1163 variants may differ in cylinder count, rating, application and equipment package; the supplied record only identifies this G-16cyl execution. Use the exact engine serial number and manufacturer documentation for rating-specific settings, wear limits and parts.

What our service work and the manufacturer documentation say about keeping this model running.
Trend cylinder exhaust temperatures, operating pressures, lube-oil condition, coolant condition and abnormal noise rather than relying only on calendar maintenance. Inspect fuel equipment, valve gear, filters, turbocharger/charge-air path and protective shutdowns in accordance with the engine PMS. Use oil analysis and inspection findings to support decisions on internal opening where permitted by the maker and class regime. After maintenance, carry out leak checks and a controlled test run while comparing cylinder balance and protection functions. Class survey may include records, safety devices, crankcase protection, remote shutdowns and selected internal components depending on survey scope. Refer to the manufacturer documentation for all exact service intervals, torque values, clearances and wear limits.

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Class surveyor typically checks engine performance, vibration, and noise levels, as well as inspecting critical components such as cylinder liners, piston rings, and crankshaft bearings for wear or damage.
Estimated lifetime: 20000-30000 hours
Carry consumable filter elements, gasket and O-ring kits, injector-related service spares, selected valve-gear components and approved sensors or switches according to vessel criticality. For an essential generator engine, consider a serviceable fuel injector, fuel-pump components, starting-system spares and maker-recommended cylinder-head or valve spares. Major rotating and bearing parts should be planned according to voyage profile and supply-chain risk rather than ordered by generic engine-series name.
