VEHICLE DESIGN
Weight and engine size

The weight is one of the
most important factors in

determining an automobile’s-.

fuel consumption especially
in city driving.

Coupled with weight is the
engine size which is needed
to provide the power
necessary for .acceleration
and sustained cruising. Put —

holds true if fuel is used
instead of people.

Engine efficiency

The thermal efficiency of
an engine defines the
amount of total energy used
compared with the amount
of mechanical output. Most
modern engines have ef-
ficiencies ranging from 10
per cent to 30 per cent.

Most engines waste much
more energy than they put to
a useful purpose. Diesel
engines are among the most
efficient; stratified charge,
and conventional, follow in
descending order of ef-
ficiency. ¢/ .
