="Econologie"]OMG !...A such engine seems very difficult to build...
Yes, first production and prototype are difficult tu build.Right now we not have a complex formulae at this engine.But only design rght now is difficult. In factory this engine need serial elements -piston -rods-crankshaft combination in a new block engine.
Advantages -1 .No collision elements (ask pilots, but on road blocked popped with pistons made too danger situation)
As you can see, the construction is very simple and is an "ocean of new ideas", as one reviewer said.
I made two going prototypes,and have a little expirens
After analyzing the results, I was surprised that the intake volume changes while the angle between the crankshafts changes (!!). This change, as the parameters and sizes of the diameters and strokes of all three pistons is constant, is little - but in a range of possible work of the engine - can reach few percent.
The minimal chamber volume can vary about to 400%, which was a huge surprise. This calculations revealed the possibility of the compression ratio change from 7 to 24 (!!).Minimal room is not 360 degrees of turns of main axes also, as we are acclimated for it. The minimal chamber volume is in radically other point of the crankshaft rotation - not traditionally in 360 deg, but in 375 deg, 15 deg after the T.D.C. (U.D.C.) where the torque of the (shoulder) arm-crank is much greater. This several degrees takes a stand after external expression of main crush which minimum surely big increase of rotary moment will cause that - maximum gas power acts on greatest shoulder of crank of axis.
I cannot exactly say, what it would incorporate in combustion process, because it is a very new, DYNAMIC and VARIABLE â€œcombustion area.â€
Temperature in combustion area no hight, because pistons are made aluminum -temperature work about 350 deg Celsius. This advantages of 800 deg traditional popped exhaust valve. -Possible height compression ratio, and difficult made NOx -whose they emerge up of 600 deg Celsius.
Right now, a lot of advantages of this idea can be seen - variable compression ratio, while changing the angle between crankshafts for all own cylinders in the engine, by adjusting only ONE mechanism.
I estimate that the fuel consumption would be affected with:
- Bigger volume capacity - better efficiency (- 20% )
- variable compression ratio ( - 10 % )
- lack of the valve springs - less power needed to operate them the timing gear ( - 10 % in full power-in no full power largest)
- possible changes of intake and exhaust angles ( - 10 % )
- mechanically forced combustion process ( - 5% )
The geometrical and thermodynamically issues are not so obvious, while considering such old construction. One of the most important advantages is that there are NO elements working percussively. The well lubricated, pistons are working silently and smoothly. Any crankshaft or timing gear failure does not cause any additional failure to the engine. This is a big improvement in reliability. In addition to this there is almost no limitation of rpm, while considering the timing gear. There is no valve's clearance and no service it, no such a thing in here. The endurance of the set of main pistons is the only thing that limits the rpm. The power can be too received from the timing gear, which is important, for e.g., for aircraft engines - where the rpm should be rather low, because of the propeller. In other construction this â€œlow rpmâ€ power will advantageous e.g. in agrimotor.
The design of the engine could be very simple, because it can be made of only one block, eliminating the overhead, and complications that come with it.(gasket, e.g.) The dynamic and combustion forces are relatively different to a popped valve engine. It's worth to mention that the minimal volume capacity is about 15 deg after after the T.D.C the main piston turn, what affects surely the torque, because the arm-crank is much greater then. The arm crank of the exhaust piston is 70-120 deg after the T.D.C , while the greatest combustion forces take place - it may cause a strange effect - the maximum torque can be taken from the smallest piston (!!). The concept of receiving power from the timing gear can be really interesting and improving.
While we consider the possible combinations of all of these elements, we could even reach one billion combinations.(!!) The first thing to do I guess is to create a software that could calculate all of these elements, using rather a really powerful computer, to simulate the engine behavior and make the first design easier. Perhaps this invention, because of it's unique features, will be a start of a new internal combustion science division.
May be these advantages will enough to start design new engine. I have a little expires, and I can help.
