Inventor's appearance on 33.
Motorship Propulsion and Emissions Conference 2011
in Copenhagen generated real interest — almost one-and-half hundred
representatives of companies all over the world were requesting for more
detailed informations (including one of the world's largest producer of
i.a. engines and heavy trucks). We're allowed to make assumption, that the
moment of mass production of gun-engine is getting closer, but negotiations
are underway, and nothing has been signed yet.
In Prague, end of Juni 2011, Inventor presented his works — this
time from theoretical side rather, exposing his conclusions about the need
to change the orientation of research on the engines as thermodynamic systems,
by replacing thermodynamic Diesel-cycle with the quite new cycle.
What is Gun-Engine? It's environmentally friendly and
transmission-free engine based on the same mechanics as how a bullet is shot
from a gun. The engine can run on any liquid or gaseous fuel, including
acetylene. Initial test results showed 92% efficiency. As a consequention,
it has much longer mileage: around 450 MPG.
The fuel is vaporized before going into the combustion chamber. Vaporized
fuel combusts much more rapidly. The piston moves against an air chamber,
which then pushes it back into position in a spring-like action once the
combustion is complete. This prevents mechanical stress on the components.
Water is injected 8 parts per one part fuel, along with the fuel. As the
fuel combusts, the heat turns the water to steam, augmenting the expansion
in the chamber. This also absorbs the heat so that the run temperature is
much lower. The exhaust is only 140 degrees Fahrenheit.
The gun-engine does not require any exhaust treatment, thus it does not
have catalytic converter. The formation of NOx is blocked by the superior
design that does not synthesize pollutants. The efficiency is high (above
95%) because the gun-engine is cooled internally and the cooling preserves
heat that is than converted into additional work. The design of the
gun-engine eliminated all causes of inefficiency in current engines
inherited from the first prototypes of Otto and Diesel inventions. The myth
that engines must be inefficient is exposed! -- Stan (August 15, 2008)
Why the name Gun-Engine?
Of course, almost all of the above (with exception of additional piston)
you can find in Otto engine as well. There is still a significant
difference: Gun-Engine uses detonation for energy release — while Otto
(and Diesel) engine uses combustion, which is much slower process.
- barrel resembles cylinder;
- bullet resembles piston (that additional one);
- primer resembles ignition;
- case of ammo resembles combustion chamber;
- powder stores chemical energy similar to fuel;
When a gun barrel prolongs cylinder of traditional engine the combination
is a new engine that is the gun-engine, with one exception that the gun is
replaced with a gun-device that uses fuel instead of powder, but the
operation is similar in both.
When squeezing trigger powder explodes and bullet accelerates towards
piston, which compresses air in the space of barrel and cylinder. As bullets
flies towards the piston it compresses air, thus pressure over piston rises
until it is as high as that of resulting powder detonation. Thus bullet
stops rebounding and the process reverses.
Proper selection of the mass of bullet and powder causes that the max
pressure occurs when crank is horizontal, which boosts torque up to 100
times. and also makes torque independent from speed, which allows
elimination of transmission in cars.
