  • Used to force more air only to the cylinder of a gasoline engine

  • Usually of the rotary screw or the centrifugal type

  • used to increase power output

  • never used on gasoline engines

Explanation

Question 2 of 10

Explanation

Question 3 of 10

1

Scavenging is:

Select one of the following:

  • The supplying of air for combustion

  • The removal of exhaust gases from the cylinder

  • Used in all diesel engines

  • Usually used in four-stroke cycle engines

  • Re-circulation of exhaust gases to reduce emmisions

Explanation
