Question

doubling the engine cylinder diameter increases the Piston trust by

Answer 1

hii dearuuuuu!!

here ur amswer^_^

▪▪If you increase the bore diameter keeping the stroke length constant, then the engine will become over square engine.( Bore to stroke ratio greater than 1)

>><<<This type of engines have both advantages and disadvantages.

>>>><<<Coming to advantages, by increasing the bore diameter the engine can run at higher speeds that means the power of the engine can be increased.it also has higher possible RPM

>>><Also the Frictional losses are minimised and crank stress is lowered

>><<<Now coming to disadvantages, since there is a bulky cabin at the combustion chamber, the developed heat energy after the power stroke will have a chance to escape to the surroundings of the cylinder. This will decrease the thermal efficiency of the engine.

>>><<<The size of the ignition chamber can cause inhomogeneity in the mixing of air and fuel and can increase the emissions of the engine..

!!hopr help u plz mark brainlist dear!!
