Scavenging Systems, Scavenging Pumps and Types of Supercharger

Scavenging Systems:

There are three types of scavenging systems

a.      Uniflow scavenging.

b.      Cross scavenging.

c.       Loop scavenging.

  Scavenging Pumps:

There are four types of scavenging pumps

1.      Crank case.

2.      Pistions.

3.      Roots.

4.      Centrifugal blows.

Types of Supercharger:

o. Centrifugal compressor.

o. Reciprocating compressor.

o. Root blowers compressor.

Turbo Charger:

When the supercharger is driven by exhaust gases from the engine is called turbo Charger.

What is Super-Charging?

It is defined as supply of compressed air during suction. 

Objectives of Super charging:

a.      To increase the output for a given bilb and weight of the engine.

b.      To compensate for power loss when the engine is operating at high altitude.
