should remember one thing...For designing a vehicle, the designer
looks for POWER of an engine. This is NOT dependent on size of the
engine. Case in point 2-stroke and 4-strokes put out different
amounts of power at roughly the same size. The reason some engines are
used instead of others is the factors of fuel efficiency,
weight(different from size), and fuel mixture, and etc.
Instead of basing the engine and speed of a vehicle of NERPS (which is
size, right?) how about using engine power units (call them EPUs).
Here is a basic kind of table.
Engine EPU Rating Fuel Economy (Miles Per Energy Unit)
------ ---------- ------------------------------------
V-Twin 4 120 40(F)
V-Twin 6 200 36(F)
Turbine Electric 280 45(E)
DC Brushless 200 60(E)
AC Induction 150 80(E)
Note: E -> Electric Source
F -> Liquid Fuel Source
Several over engine types and even specifcs can be added.
Once the EPU of the engine is picked then the transmission could be
chosen to give the car the performance needed (top speed, acceleration).
Transmissions could be of any gear ratio combination. The effects
would really only be noticed in the speeds of the vehicle for game
purposes. For simplicity only about 3 or 4 different kinds of
transmissions need be used. This would allow the designer to tailor
the car to a specific performance nitch. The transmission would also
allow easy computation of the cars performance stats from the engine
EPU, vehicle weight, and etc. In other words the transmission could
act as the conversion factor from EPU and weight to speed.
What do you think? Comments?
