what is blow by and blow down phenomena in ic engine?
Answer Posted / kk
Blow-by occurs when the explosion that occurs in your
engine's combustion chamber causes fuel, air and moisture
to be forced past the rings into the crankcase. Your
engine's rings must maintain an excellent fit in order to
contain the pressure.
Blowdown is the amount of time/distance/degrees between
exhaust port opening and transfer port opening.
The absolute most accurate description of blowdown would
be... the amount of TIME between the exhaust and transfer
port openings. This "measurement" would of course only be
accurate at one rpm, so blowdown is commonly referred to in
degrees of crank rotation.
