I am the woodworking enthusiast mentioned in this post.

 

I tried to explain how I tried to make the Parson's design to no avail on my web site....

 

If you can tell me how to make it work, please let me know.  You cana email me from my web site linked above.

 

thanks

 

Dale

Depending on the demand this technology could be used for two and / or four stroke engines

Velocity of piston and rack assembly: An integral cam that work between segmental wheels, explained earlier, would work as a shock absorber to decelerate and accelerate the assembly at TDC and BDC. So the velocity curve is not a square wave. It would be just like a sine curve with a straight line at the top. Starting 45 degrees is like a sine curve's 0 to 90 degrees, the next 90 degrees is a horizontal line parallel to x axis and the ending 45 degrees is like the 90 to 180 degrees of a sine curve

@jhmumford: I can't give anything away, but if you think that two-stroke engines are "very polluting and inefficient," you may want to stay tuned for the new product that Evinrude will be revealing in less than two weeks.

Evinrude's first-generation E-TEC engines (DI two-stroke), which came out about ten years ago, were the first outboards to receive the EPA's Clean Air Award... and still have the lowest reportable emissions of any outboard, two-stroke or four-stroke.  Now Evinrude is planning to unveil a new era of ourboards.  All I can say is: prepare to be surprised.

@EdDanzer – I am sure these manufacturers already know this and have taken a step further to prevent this happening.

@Dave – I think its already being a competition to the ordinary crankshaft engine. The power the fuel consumption itself brings this engine forward.

@a.saji – a good point, I think it should be able to handle at least 10000 RPM referring to the torque chart.

More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
As additive manufacturing (including 3D printing) becomes increasingly popular among businesses as a quick and easy solution to creating and evaluating prototypes and end-use products, the debate about whether to outsource production or to purchase equipment for in-house use is at the forefront of industry discussions.
With increasing terrorist threats overseas, organizations are thinking about how best to defend themselves here and abroad. Engineering can play a role, especially when it comes to putting a barrier between yourself and the bad guys.
Time to market is everything, but at the same time, you canít sacrifice quality for speed. Thatís where additive manufacturing comes into play.
In the last few years, use of CFD in building design has increased manifolds. Computational fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
