This package describes in detail the correct running of slow and medium speed diesel engines. Aimed at all shipboard engineers and engineering cadets, it will help avoid problems associated with running inefficiently, informs viewers of the environmental aspects of diesel engine emissions and alerts them to the warning signs of serious and costly breakdown. All the main components of a diesel-powered system are described including fuel storage and purification. The importance of correct fuel oil sampling is stressed and the analysis of samples in the laboratory is shown. Animation is used to show in detail the atomisation and burning of fuel within the engine's cylinders. We also see the monitoring of engine performance and the taking of traditional indicator cards as well as the use of their electronic successors. The package explains how deviations from the standard indicator plots can reveal timing and injection faults. Two typical scenarios are shown in which the engineers respond to indications of poor functioning and methodically arrive at the respective causes. Finally components are shown which have suffered real damage in service and the package stresses the importance of adhering to prescribed maintenance schedules.
