"Reasoning against scientific belief" I have no education but Mr Moore was a college grad. In his patent with the early close Atkinson cycle it says "With the sub-atmospheric compression,less than a full charge is used with each cycle. Thus,a larger engine would have to be used to obtain the...

Vincent Bless you for your comments. Clyde Bryant has several diesel patents that are basically the same thing I am saying about gasoline engines (6,279,550) So I would like to know how many of these critics that are saying I don't understand the fundamentals of engine design have ever built...

Why am I being repeatedly asked to answer questions that are explained with relevant SAE references in my patent 4,961,406? Obviously most of you are younger and far more educated than I am. That being said I am the first person who ever applied for a patent on the concept of using a detonation...

Ken The SAE papers mentioned in the patent give lots of the information you are looking for. What you are asking is like asking what the valve timing is for an Atkinson engine. Its a ratio thing, the more restrictive the VE the higher the expansion ratio that can be tolerated. The...

Isn't this basically an arguement about the chicken and the egg? I would argue that heat is what causes detonation. Heat is certainly impacted by how long the mixture is in the cylinder. My limited experience with a dyno has demonstrated that an engine will make more power at high speed on low...

You aren't going to get me to challenge that post

As politely as possible I will suggest you have it all wrong Does high octane fuel burn slower than low octane fuel? Which fuel resist detonation better at low speed heavy load conditions? Earlier than normal intake valve closing will increase low speed VE because in a fixed event camshaft...

I understand that this doesn't sound logical. When I first stumbled into this scenario we were didn't believe the data. We put the baseline cam back in the engine and another late close intake cam and we couldn't even get close to the same low speed numbers we got with the early close. I...

It is very hard to compress 30 years of research, 12 patent 10 prototype engines two of which were put in cars into a message. I am not computer skilled to cut and paste reference data in this message but all the reference data is in the patent. The best way I can say it is at low speed you...

Turbulence is good for fast burn at light load but at high load turbulence is terrible for detonation. At high load, lower speed, you want less turbulence and uniform mixing without to much atomization. The best tool to achieve burn control is proper variable control of the intake valves which...

I would not advocate IVT in a multi cylinder engine. I would suggest a search at the USPTO and SAE engineering papers on the subject to learn more about IVT. E85 will always be inferior to gasoline in MPG but on power E85 is great IF you use high compression. E85 may be unavailable in some...

IVT in a single cylinder engine is comlicated and expensive? Have you ever seen a single cylinder IVT Cadillac from the early 1900's? As a side bar - wouldn't all this be much easier to achieve by just setting small engines up as E85 fueled? I built IVT prototype engines for Ford GM and...

I think reinventing the wheel is an accurate summary of this thread. External EGR is like from the stoneages. Just look at the auto industry. The world is moving to internal EGR for reasons previously mentioned. Have any of you thought about the complications of fire from refueling and...

The biggest emission challenge facing the internal combustion engine is reducing cold start emissions. All the electronic gizmo's in the world can't surpass the clean start characteristics of Intake valve throttling due to the sonic atomization benefit not being dependent on engine temperature...

I have 13 patents related to variable valve timing. To answer this question you would need to tell be if you are talking flathead or OHV application. There are over 700 patents pending related to variable valve timing that you can easily view at the USPTO site. As I understand it the largest...

I would ask you to rethink that statement that the small engine industry can't afford variable valve timing. What if the single cylinder engines were intake valve throttled? Thats how the small engine industry was birthed. You can pick up internal EGR by altering valve event size or valve...

Internal EGR is implemented via variable valve timing and internal EGR is cooler than external EGR which reduces the potential detonation limited power loss. Internal EGR is superior to external EGR in all respects. This was all known 30 years ago. Makes you wonder why they just didn't do...

Patent 3,714,932 has some great information on the virtues of internal EGR derived from VVT and external EGR. In a nutshell Internal EGR is vastly superior to external EGR in accelerating engine warm up. Internal EGR is superior to external EGR in reducing hydrocarbon emissions because the...

In the 1980's I designed 7 intake valve throttled engines for Gm,Ford and Chrysler. My conclusion was its a great thing in a laboratory but isn't practical in mainstream cars. 1st its dificult to have all valve events the same at all operating conditions. Secondly IVT is great for light load...
