Pressure-Time Curve and Power for a Diesel Engine

by Chad McCann

Submitted : Fall 2012

Diesel engines are used in nearly all large ocean ships in the world due to the fact that they provide the highest thermal efficiency of any regular internal combustion engine (Stewart 2011). Even though these types of engines are very efficient at converting chemical energy to mechanical energy, losses in efficiency can still occur by over powering a vessel. By using measured pressures inside an engine it is possible to calculate the work that can be done by the engine. Once you know the exact work done by an engine it can be applied to a vessel that requires that exact amount of work to perform the desired task.
