How the Rabbit works 
The Diesel. 
Oil is a natural liquid energy-storage 
system. It is produced by burying 
undecomposed organic matter under 
hundreds of tons of pressure for 
200 million years. Prudence dictates that 
we use it sparingly. 
Which is the fundamental advantage of 
Dr. Rudolph Diesel's compression ignition 
engine. Speed and power are controlled 
directly by restricting the fuel supply. 
The engine can have all the air it wants, 
but only enough fuel to accomplish the 
pb at hand. At idle, that can be as low 
as 4 tablespoons an hour. Although very 
efficient, it is also very slow and heavy, 
unfortunately placing it at odds with 
the concept of the small passenger car.
