The quest of human
beings to develop engines with high power, high torque, less vibration and most
essentially with no pollution is on since the discovery and development of
engine. Stirling engine is just one step forward towards the creation of a
noise free and pollution less engine.
The Stirling engine is the engine, which
uses a fixed amount of gas sealed inside a cylinder. The expansion and
contraction of the gas, using heat from external source, creates the useful
work. The main advantage of this engine is its capability to use any type of
fuel and the emission of no exhaust gases.
Due to this pollution free and use of
any type of fuel characteristics the Stirling engine shows a greater potential
over any other type of engine existing today. To consolidate this claim an
effort has been made to develop a working model of Stirling engine.
All of us including
the lamest of laymen would have at one time or another experienced problems
with our vehicles engine and most of the time after moaning and cursing finally
in line with the universe and accepting our doom we would have coughed up the
cash for repairs and parts and insistently taken old parts home, disregarding
the fact that no descent human would have wanted them and during this exercise
in existence it is doubtful that anybody would have chance to miss seeing a
piston or two, this ubiquitous creatures that scurry up and down in an enclosed
cylindrical space, getting their crowns slammed regularly and
unceremoniously…eventually to be thrown aside and replaced by a marginally wider
chap. Doubtful that any of us would be able to imagine modern travel without an
internal combustion cycle. Hell if we ask our mechanic if he has ever seen a
vehicle without any exhaust then he is probably going to refer to you to the
nearest shrink.
So an engine without any exhaust gas is
a mirage or it can be a reality? The answer for this is definitely yes. We can
have an engine without any exhaust gas and that is what a Stirling engine is.
