TPI
« on: May 12, 2019, 06:20:22 PM »
A big thank you to Ray Smith for resurrecting this site. Rebooting all the old stuff on My Fuel injection development has paid dividends in terms of a resource  to show time lines for the development as it happened in real time. KTM recently tried to patent the TPI system, claiming they invented it. Actually a recent article put out by KTM now claims they accidentally " discovered'' TPI in 2014 , perhaps here on TSM I would say , but never the less a patent was applied for. TM, understanding that TPI was free for any manufacturer to use has set up and is starting to sell 300 TPI enduro bikes. They were unhappy that KTM tried to pull this greedy trick. They came to me for help to stop this patent application, understanding that I had done TPI first and published it . I pointed them to this web site where there is a time line on development. I have heard that the KTM patent application has been declined because of the appeal TM has put up, using TSM as a heads up. So this means TPI is now free for any manufacturer to use. Good for twostrokes.

Go buy a TM ;D

You are welcome.

Your documentation of that design was how I found TSM in the first place. I was saddened by its loss when the server crashed and was a big part of why I worked to get the original content back.

I am glad it paid off.

(BTW my name is Ron :)

Opps, sorry Ron , for some reason I always thought it was Ray? Please accept my apologies.
Im keen to post on my mk2 system but have promised TM I will keep mum about it at the moment. In the next few months will be make or brake, Im about to finally finish my 360 rotary valve revers cylinder mk2 TPI engine, Ive told TM if they do not do something with mk2 TPI by then, I'm publishing it, here.

I can and will post some update pictures, just with a rag over the cylinder for now, there is a lot more to this engine  apart from just the mk2 TPI.
