Question { L&T, 9042 }
the avg piston speed of an internal combution engine
increases as cylinder dimension decreases justify?
Answer
as mean piston speed = 2*L*N ,
L=stroke length ,N=crank speed,
for constant power output at constant speed of engine i
directly propertional to L as (Bp=P*L*A*N/60).
so mean piston speed increases.
