It would be a real problem doing a valve adjustment on your x engine buddy oh pal

How do you manufacture this groove? Typically camshafts (3) are ground and you cant do this.

You cannot machine it because the other lobe is in the way.

How do you adjust the valve clearances?...

Half of the Pattakon's pre engine showing an 85mm bore piston made from 6061 Aluminium at 450g. The whole piston will be 900g. An equivalent piston from a conventional engine weighs about 300g.

Here is yet another analysis that I have found. This one assesses the shaft. According to this diagram, the multi cylinder versions will increase the twisting load and it is calculated that the shaft...

Please review this analysis of the Pattakon engine that I sourced.

It was calculated using a standard combustion peak pressure. It was much worse in alloy. Steel mass 1.228kg with an...

Mate no offence but you sound like a real wanker with a comment like that. You obviously earn no more than $80k/year for a second rate engineering firm and you think that you can simply pass...

Mate, are you sure you have worked on a project of any significance before? Since when do projects, especially prototype projects, run on time? When dealing with innovation and limited resources...

Hightower99, for an explanation on teh technology, looks at their web site or read over teh previous 19 pages for an explanation, it is all there.

Isnt the issue here FUEL ECONOMY not performance orientation?

So from a fuel economy perspective, are we better having torque down low or up high???
