cooler air; second, it results in an air charge of
higher density and pressure at the end of the suc-
tion stroke. The provision of a greater amount of
fresh air permits the combustion of a greater
quantity of fuel and, consequently, a higher out-
put from a turbo-charged engine than from one
not so equipped.
Scavenging the combustion space with fresh
air cools the cylinder head, cylinder walls, valves
and piston. For this reason a greater amount of
fuel can be burned, and greater power devel-
oped in an engine turbo-charged with the Buchi
system without harmful effects on these engine
parts due to excessive heat. The speed and out-
put of the turbo-chargers vary automatically and
promptly with variations in engine load or speed.
