Smallest:
Not much bigger than a stack of pennies, the "mini engine" is the first engine of its size to deliver power on a continuous basis.
Currently will produce 2.5 watts of electricity (0.00335 hp).
Uses 1/2 fluid ounce of fuel per hour
PRESSURE
The cylinder pressure is not constant. It is highest right after combustion, as much as 2,000 psi, and decreases as the piston moves away from the cylinder head.
Horsepower
A unit of power developed by James Watt to provide a basis for comparing the amount of power produced by horses and other engines.
