I notice that the difference is using pistons instead of valves. But I would like to know the benefits in terms of power, torque, durability and rpm."
a brief summary of:
So yeah .. I made two prototype engines in such a system. First, this is my thesis at the Technical University. He had to show that the engine has the possibility to work at all. The assumption has done surprisingly well ..
My second prototype, with many improvements done and its description and photos are on my website. The idea was it to work in the car Fiat 126 p on car races, which were held in Poland at the time. In my assumptions had he gives an output of around 100 horsepower at 10 000 revolutions. I made a prototype with its design and start-up to a satisfactory level of about 3 years (1000 days) View as a day of work takes a good mechanic replacing a head gasket does not, for example, in the "Lotus", and you will know the approximate costs are such a prototype and its launch . ...
All these costs were, funding of my personal funds ..
But it was worth it. Flagellum yes - inventions also sometimes surprising, in a good way. Not everything new has to be wrong. IN THIS case in good page surprise was even beyond the scope of forecasts. Namely, how are the practice has shown a prototype of the engine has an output of around 250 horsepower at 10 000 revolutions .. it is dwai know half times than the expected value. with such a large difference, finding out about it was a big threat to life ... Here a little more fully described.
Due to this process, the engine is so big power from a relatively weak engine, its use in a racing car does not make sense, because the engine would have already collapsed at the start, using his full power. Also I did not want to risk because of this, the startup was repeatedly dismantled because some surprised me, not only when it comes to the same power. These repeated cutting weakened some of its elements, so they can no longer be too much to repeat ... But at the moment, have the engine in ready to work .. You can screw it to the 10 000 cycles. Unfortunately, I will not let the torque measurement, because it would crash ended his .. Just a reality this time by two and a half times, and so exceeded the limit of sustainability, the design ..
Strange that since 2005, despite the existence of this site, no one was willing to see the prototype at work .. However, questions are asked, and sure. You maybe someone thinks that the data you publish false. . Really, please bear the costs of a visit, and so they will be much than the venue of the construction of its new prototype, and of course a few blunders that and I had .. Operation of the engine, is in every respect a surprise in the right direction .. Maybe instead of theorizing, it is worth it alone to see for yourself.
If it comes to SERVICE LIFE is sure it will be a lot more stable, because most emergency items in today's engines are running timing and head gasket, In my design of these elements is not .....
As regards the speed that is a structure that allows no low speed, up to 30 000 revolutions of the main shaft .. crak timing schaft spins then only 15 000 cycles, while maintaining constant high precision charge exchange as the existing structure does not guarantee,
The engine has a huge advantage. The most hot item in the combustion chamber heats up, no more than 250 degrees Celsius. This is a huge advantage, because at this temperature does not occur in the most harmful NOx pollution, .. Of course, the compression ratio can also pick up a lot ..
Adding up all the advantages and possible regulatory tions, you will get about 50 % fuel efficiency, with the same parameters driving ...
Well unless you do not believe the Displacement gives more power ..
