the energy in an IC engine is produced by the burning of
fuel in each power stroke..inefficiency is created in many
much of this heat energy is lost with exhaust gas,by
convection,conduction and radiation from the cylinder..only
some of it is converted to useful energy i.e in pushing the
piston down rapidly..this is the major cause of inefficiency
in IC engines.. after ehich various mechanical losses like
friction comes in...
The major loss is "heat loss". Efficiency of an IC engine
wrt to the carnot efficiency i.e. max possible efficiency.
Since we are unable to harness all the heat produced into
work, efficiency is very low.
Other reasons of loss of efficiency are as above, valve
timing, friction and all those. but the major cause is heat
If a fixed gear having 200 teeth is in mesh with another
gear having 50 teeth.The two gear are connected by an
arm.What will be the number of turn made by the smaller gear
for one revolution of arm about the center of bigger gear?
Any effort is appreciable witha proper logic..
