Thank you.
So do I.
Screwing off parts and screwing them back on a unit which someone else designed and built is not clever.
They also are doingbresearch into a reversed rotary. The seals are on the engiens block and can be replaced as a DIY job.
Yoiu said " I haven't -". Which says it all.
When? 1890?
You don't say....
Piston engine won because they are afraid to move away from a technology that makes them billions. they want the status quo. They don't want advancement. Orbital of Australia perfected the 2-stroke about 12 years ago. It passed the California emissions. A unit was made for cars: half the weight 50% more mpg, half the size, revs like hell as no valves, quiet (no valves again), etc. A car with one in which the body was designed around it could double current mpg with no affects in performance. Why don't we see them in cars? Mmmmmmm, mmmm A few are in boats.
Get this balls out of your head, that if anything was good enough the big boys would be using it. The car industry is tooled up for the piston engine with their mentality geared that way, and can't turn around, unless forced by legislation.
A small English company is developing a cross between a turbine and a piston engine that is being taken up for combined heat and power applications in Holland. This promises a lot.
