Answer / karan singh

As we know that a cylinder contains four functions that are
suction, combustion, expansion and exhaust. If cylinder
dimensions decreases then compression in a cylinder
increase with high pressure and and increase in a pressure
in expansion also. Due to that exhaust provide large output
and the Piston movement increases.

Answer / mazhar sunil

as the dimension of cylender deccreas the speed increases
because the volume of cylender decreases the compression
developed in cylinder increas as the result piston moves
speed

Answer / im5690

when the cylinder dimensions reduce so does the crank radii. hence the smaller dim of the crank leads to the increased linear speed of the piston

Answer / sukanta kumar chand

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.

Answer / nirmal

QUESTION is incorrect.piston speed remains constant
irrespective of engine size for all engines of the same
manufacturer.refer i c engine by sharma mathur chapter on s
