Scavenging process 

What is scavenging ?

Scavenging is a procedure used inwards internal combustion (ic) engine  inwards which burnt gases are forced to atmosphere from engine cylinder yesteryear using inlet pull per unit of measurement area of fresh air.

I.e scavenging is procedure inwards which exhaust gas removes yesteryear using fresh charge.

What is Scavenging procedure inwards ic engine 



Engine scavenging organization is a procedure of sweeping out halt gas yesteryear fresh accuse from cylinder is called every bit scavenging process.

Scavenging it entirely used inwards 2stroke engine inwards both si too ci engine.4 stroke engine scavenging procedure is non used.3 stroke engine too or thence fourth dimension used scavenging process. 

Scavenging it used high density of air than surrounding. But supercharging too scavenging procedure is non same.

Crown shape piston used inwards 2 stroke for deflector.this shape is of import for deflection of exhaust gas.

Scavenging inwards ii stroke used entirely non for four stroke engine.because four stroke engine has four stroke too bring separated stroke thence no exhaust removing problems.so scavenging organization is entirely used inwards entirely 2 stroke engine.

The term of scavenging is to a greater extent than frequently than non associated alongside high efficient engine.

Two stroke engine scavenging is minor inwards size than three stroke engine scavenging procedure part.



Effect of scavenging procedure on ic engine 

1) If proper scavenging procedure used too then ability output increase.

2) thermal efficiency decreases.

3) Scavenging is increasing the efficiency of ic engine is upto 95% to 100%.


Types of scavenging 

1) cross stream scavenging 
2)back/loop scavenging 
3)uniflow scavenging. 



Mcq on scavenging process 


1. When Scavenging procedure used inwards four stroke ci engine too then engine efficiency is..........

A. Below 30%
B. Between 30% to 50%
C. Between 85% to 95% 
D. Between 95% to 100%
Ans - D

2. When scavenging procedure used too then increased.............

D. Power output 
Ans - D


3. Scavenging procedure to a greater extent than frequently than non used in.....

A. 2 stroke engine 
B. four stork engine 
Ans- A

4. The air used for forcing out of burnt gases out of engine cylinder during exhaust periods that procedure is called as..............

A. Scavenging 
B. Supercharging 
C. Turbocharging 
D. None of these 
Ans - A
