Section 3 deals with the fuel consumed when the vehicle is
stationary and the engine is idling. In Section 4, the fuel consumption
of a vehicle travelling at a constant speed is analysed, and Section 5
deals with the fuel consumed during a stop/start manoeuvre. i.e. when
a vehicle decelerates from an initial steady speed to zero speed and then
accelerates up to a final steady speed. When a trip starts with the
engine cold, a fuel consumption penalty is incurred and the quantification
of that excess fuel due to cold starts is the subject of Section 6 and a
summary of the main results is given in Section 7.
