Comparision
of 2 and 4 stroke
The two
stroke engine gives an engine which..
1.has
high power / mass ratio
2.is easy
to reverse
3.has a
reduced number of moving parts and consequently requires less maintenance
Where as
the 4 stroke
1.good
volumetric efficiency
2.good
combustion characteristics
3.positive
exhaust scavenging
4.less
arduous lubrication requirements due to idle strokes which allow spread of
lubricating oil through bearings and around the liner.
