Internal/External Combustion Engines
Basically, there are two types of Combustion (Heat)
Engines. These are the INTERNAL COMBUSTION engine and the EXTERNAL COMBUSTION
engine. These names are derived from the relative location of the fuel-burning
apparatus which creates the energy to run the engines.
In the case of the External Combustion
engine the fuel is combusted outside of the main expansion chamber of the engine hence the
term External Combustion. Here, once the fuel is burnt the energy is transferred
into the expansion chamber via a medium, most commonly steam, and is converted into
mechanical energy via the movement of the piston.
Soon to be on display at Confectionery Capers will
be a fully operational 1/8 scale model of an American prototype steam
locomotive (wheel arrangement 4-8-4 ... commonly known as a 'Northern' type
locomotive) .If you would like more information, check out the
Also at Confectionery Capers you can currently see
a small working model of a stationery steam engine which operates at the press
of a button. Even though it would run perfectly on steam, it operates currently
on compressed air. Check out the animation

The Internal Combustion, or commonly the I.C. engine is
without doubt one the greatest and most useful inventions of man. The Germans Otto and Langan are generally credited with inventing the first practical I.C. engine around 1880.
Unlike the previously mentioned steam engine the I.C. engine burns it's fuel
directly within the expansion chamber - hence the name Internal Combustion.
The animation to the right demonstrates the basic
principles of operation of a four stroke I.C. engine as commonly found in
the majority of cars.
The small animation to the left shows the principal of a
two stroke I.C. engine. This design is commonly found in motor cycles and
power equipment. In general terms the two stroke engine produces more power for the
relative size of the engine but with far less fuel efficiency and greater pollution.
Since Otto and Langan's original designs the I.C. engine
has undergone steady evolution towards lighter, faster and more efficient
designs while maintaining the basic operating principles. Today it comes in hundreds
of forms and has thousands of applications in powering our modern industrial world.
