TO ALL: It is again a pleasure to inhale the fresh air at this thread. Let the spirit of harmony prevail. Silicon Investor is a discussion board where the pros and cons of various subjects are presented for the benefit of all. I would never deny Greg and his friends a platform, and I am sure he and his really don't want to deny us the same platform. Competition and controversy create the dynamics of change and that is what progress is all about. Therefore, I feel part of our "mission" is to continue to debate the strengths and weaknesses of AENG in a responsible manner. Other SI investors will come to the thread and need a full complement of facts upon which to make a decision regarding the merits of AENG. I am a little amazed that I have not been directly challenged on some of my recent statements regarding Manthey and the patents. Could it be that #s-man has stumbled (with much help from ww) upon the truth? This type of engine has a stratified charge ignition system to achieve ignition at a very low end-point mixture ratio. It may or may not use a small separate chamber to achieve a high enough mixture ratio for ignition. This results in the low exhaust temperature and probably very complete combustion. The inlet and exhaust ports of this type of engine should be spaced in such a way that the intake and power strokes are longer in time than the compression and exhaust strokes. That is the really unique feature available from this design, more efficient expansion of the hot gas and extended time to induct as compared to the equal-stroke crankshaft IC engine. Shash pointed this out as a desirable feature a month ago, and I believe Sword did some calculation on time available for induction (or lack of thereof). The cam plate can be shaped to compliment this. Dual rotating cylinder blocks could be employed. All of the above design art have been previously patented. So, what does Manthey and AENG bring to the table. Practically nothing. That is why I opined that he may be the bamboozler. Manthey's patent '"advantages" speak to thrust reduction, a poorly worded reference to reduced lubrication, a wordy paragraph about small and light and other things to be "hereinafter apparent." Wow, that is nothing compared to the 90 year history of the basic design with no buyers. Which also points up that most of the patentable features have already been patented by other people for the last 90 years, and most of those patents have already expired, again with no buyers. In other words this engine is public domain. That then brings us to the value of AENG. In my opinion it is worthless because the patents are public domain. The fact that eminent people in the motor world are impressed only means that it is taking them as long to do this homework as we have taken. 246810
