Description.
Internal combustion engine with two crank
shafts and two pistons in one cylinder.
At the beginning, when the reciprocating internal combustion engine was
invented
and developed, the fuel economy (diesel and petroleum) - wasn't live issue.
While
engineering continued to develop, the main attention was attended to engine
power,
where was improved fuel mix, spraying of fuel and etc.
Now, when the quantity of the cars, planes, ships, locomotives, agricultural
technics and any technics, using reciprocating internal combustion engine in
each field of
industry, hardly multiplied, the problem of fuel economy and engine power
increase with
the same fuel expense, became urgent.
The basic idea of how reciprocating internal combustion works can give us
device
commonly known as potato cannon. This example explained and could be found at
http://www.howstuffworks.com/engine.htm/printable.
Say that you took a big piece of plastic sewer pipe and put a cap on the end
of it.
Then you sprayed a little WD-40 into the pipe or put in a tiny drop of
gasoline. 'Then you
stuffed a potato down the pipe. When you introduce a spark, you can ignite the
fuel.
The potato cannon uses the basic principle behind any reciprocating internal
combustion
engine: if you put a tiny amount of high energy fuel (like gasoline) in a
small, enclosed
space and ignite it, an incredible amount of energy is released in the form of
expanding
gas.
The best example is an old Revolutionary War cannon (we load the cannon with
the
gun powder and a cannon ball and light it) - that is internal combustion.
If you can create a circle that allows you to set off explosions like this
hundreds of times
per minute and, if you can harness that energy in a useful way, what you have
is the core
of a car engine.
Almost all cars currently use what is called four-stroke combustion circle to
convert
gasoline into motion:
- intake stroke;
compression stroke;
combustion stroke;
exhaust stroke.
Principle of how reciprocating internal combustion engine works (on petroleum
and
diesel) we explained on example of shooting cannon, where in use only the
energy,
released from the ball's shot, flying straight ahead. But there is no use for
kick-energy of
cannon itself, which is equality to energy of cannon's ball.
Due to above-mentioned, our idea of improvement of reciprocating internal
combustion engine consist in more efficient energy using, that allow us to
increase engine
power in two times with the same fuel expense. For using of kick-energy we
suggest to
use two crank shafts in engine and two pistons in each cylinder.
In enclosed bulb - the pressure at each side of it dispart evenly (as known
from
physics).

It could fmd use in two- and four-stroke, petroleum and diesel reciprocating
internal
combustion engines.
If we would consider two- or four-stroke reciprocating internal combustion
engine,
working on petroleum or diesel, than the engine we're suggesting work by the
same
principle, like currently using.
In applying drawings we didn't identify spark plug and injector.
Let's review in one engine 2 crank shafts and in one cylinder -2 pistons,
which
move up and down, as shown in the Figure I and Figure 9/l.
1 Cycle (compression)
Figure l: Two pistons compresses fuel, moves to each other with close valves
intake and exhaust. When pistons reach the point 5-10% before the top dead
center,
the spark plug emits spark to ignite the gasoline.
2 Cycle (combustion)
Figure 2: After pistons hits the top dead center, the gasoline explodes (gases
expand in capacity many times), and it create the pressure inside the
cylinder, which
driving the pistons down (pressing on both pistons evenly). Pistons push both
crank
shafts with evenly energy and make it to rotate. Valves intake and exhaust
still close
until pistons will reach bottom dead center.
3 Cycle (exhaust)
Figure 4: After pistons hits bottom dead center of crank shafts, the exhaust
valves
opens, intake valves still close and let out exhaust, till pistons will reach
top dead
center.
4 Cycle (intake)
Figure 6: After pistons hits top dead center - the exhaust valves will close
and
intake valves will open. Next goes the intake cycle of new charge of gasoline,
till
pistons reach the bottom dead center.
Now engine will go through all these cycles again consistency.
Figure 9: Pay-load goes on flywheel with assistance of crank shaft's
cogwheels.
This pay-load could be use the same way at the currently using engines.
Figure 9/l: Describes parts of engine.
Figure 10: If we would follow our idea: valves - intake and exhaust - possible
to
place not only in the center, but also around the cylinder and in any
cylinder's point.
