= "Econology"] OMG! ... To such an engine seems very difficult to build ...
Yes, first production and prototype are difficult to build.Right now we have a complex formula at this engine.But only design 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 dangerous 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 volume changes 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 small - but in a range of possible work of the engine - can reach few percent.
The minimum chamber volume can be compared to 400%, which was a huge surprise. This calculations reveals the possibility of the compression ratio change from 7 to 24 (!). Minimal room is not 360. The minimal chamber volume in the crankshaft rotation - not traditionally in 360 deg, but in 375 deg, 15 deg after the TDC (UDC) where the torque of the arm-crank is much greater. This is one of the most important steps in the evolution of the market.
I can not exactly say, what it would be in combustion process, because it is a new, DYNAMIC and VARIABLE â € œcombustion area.â € ???
Temperature in combustion area no hight, because pistons are made of aluminum -temperature work about 350 deg Celsius. This benefits of 800 traditional popped exhaust valve. -Possible height compression ratio, and difficult made NOx -whose they emerge up to 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 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 the timing gear (- 10% in full power-in
- 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 is that there are NO elements working percussively. The well lubricated, pistons are working silently and smoothly. Any crankshaft or timing gear does not cause any additional failure to the engine. This is a big improvement in reliability. In addition to this, it is almost no limitation of rpm, while considering the timing gear. There is no valve and no service, no such a thing in here. The endurance of the set of pistons is the only thing that limits the rpm. The power can be used for timing engines, which is important, for eg, for aircraft engines - where the rpm should be rather low, because of the propeller. In other construction this â € œlow rpmâ € ??? power will be able eg in agrimotor.
The design of the engine could be very simple, because it eliminates the overhead, and complications that come with it (gasket, eg) The dynamic and combustion forces are relatively different to a popped valve engine. It is worth mentioning that the minimum volume is about the piston turn, which affects the torque, because the arm-crank is much greater then. The arm crank of the piston is 15-70 deg after the TDC, while the greatest combustion forces take place - it can 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 these elements, we could consider the possibility of using a very powerful computer. , to simulate the engine behavior and make the first design easier. Perhaps this invention, because of its unique features, will be a start of a new internal combustion science division.
May be these advantages will be enough to start design new engine. I have a little expires, and I can help.
