The article discusses the author's experience of measuring the rejected heat rate of a diesel engine for a U.S. Navy ship. The ship had been designed to a rejected heat rate of 4 million British thermal unit per hour (Btuh) from each of the ship's four engines. The author measured a total of 2.75 million Btuh heat production from the engine, less than the 4 million Btuh specified by its manufacturer. As a result, a fifth engine was installed in every ship.

    The paper details a wholly analytical approach to heat release modelling. The approach is based on the diffusion combustion process which is specific to diesel engines operating under very high injection pressures. The combustion is subsequently controlled mainly by two items, the instantaneous...
