Whatis heat engine?
Heat
engineswork
on theprincipleof converting
chemical
energyinto
mechanical workand
evolve from external combustion engine to internal combustion engine. External
combustion engineis theheat
enginein
which fuel combustion takes
placeexternal to
cylinder.
Dueto this
it is bulkyand
consumes lot of place.Secondrevolution ofheat engines are
ICE in which fuel combustion takes
internallyand consumes less place and
became compact,cost effective.Of latethird revolution isNANO
Internal
CombustionEngine. It is difficult to
thread-ina needle. Imagineworking
with aninstrument with
one
billionth ofmetre. Download : Nano IC Engine
