An example of the output graph produced using this procedure, for a two-day
cycle, is shown in Figure 5.5.

5.1.5 Other Vehicle Types
The discussions so far have focussed on land vehicles, but the same processes
can be equally applied to aeroplanes and boats providing that fuel consumption
and range data are available [6,7]. Diesel trains could also be run on biodiesel,
and the processes, again, would be the same. However, electricity demand from
electric trains would be more easily modelled at the demand profile selection
stage as a direct electricity demand, due to the way in which consumption data is
available.
5.2 Internal Combustion and Diesel Engine Modelling
There are two possible ways to approach the performance modelling of internal
combustion or diesel engines. Firstly, the combustion process and
thermodynamic cycle could be explicitly modelled, in order to predict the
performance of different engine designs. This approach, however, would
require a large volume of data that would not be easily available (much of which
