Maintenance is becoming increasingly an important element in the upkeep of the modern complex equipment. There are a number of approaches to the maintenance of the equipment such as the break down maintenance and preventive maintenance. Marine diesel engines require proper maintenance to ensure their efficient, safe and trouble-free operation. The preventive maintenance task that is most useful for reducing the overall maintenance, is also known as on-condition maintenance, condition-directed maintenance, or predictive maintenance. This is done by measuring some parameter over time where it has been established that parameter correlates well with the incipient failure conditions. This paper contains the studies of the evaluation of combustion chamber leakage of four stroke marine diesel engines by using a diagnostic device. It describes the methodology to develop the performance limits of the combustion chamber leakage of marine diesel engine and the method of evaluating the condition of diesel engines. The results of model tests of the diagnostic device, Pneumatic Indicator, are also reported. The proposed methodology allows performing the evaluation of the technical condition of a cylinder piston group of marine engines both qualitative and quantitative. Thus the maintenance and repairing works may be performed according to the real condition of the engine, which is extremely useful in decreasing the overall maintenance cost.
