Answer the following statements by True or False:
1. Superchargers are used to increase the power of an IC engine by raising the
intake pressure and thus allowing more fuel to be burned per cycle.
2. Scavenging is the process by which the oil rings scrape the lubricating oil
from the cylinder wall and allow the oil to return to the oil pan.
3. The power output of a two-stroke engine equals that of a four-stroke engine
for the same displacement.
4. After coolers are used after the compressor to drop the air temperature and thus
