Re: Quiet recently

Been away for a long time. Friends died, buisiness down the drain. Health issues. All that time my DIZH has been waiting for me in a dark corner. Getting it in running state is one of the last small fires still burning inside me. Today I pushed myself to make a start again. A lot of crucial parts we...

Re: wasted horsepower

Thanks Tappy, for the backup. I've ran some tests at my workshop. I took a flywheel and cover from a seized yanclone(10hp) and connected them to a testbench used for testing electrical pumps. The bench showed that running at 3600 rpm the fins use 1.87 kW electrical power. So this is on top of what t...

Re: Punsun Dnepr build completed

Here is the problem. In holland, when you switch from gasoline to diesel, under the new rules the bike has to comply to these rules as if it was a new bike. This means that no matter how old your frame is, it has to be fitted with indication lights, proper brakes, proper headlights, modern (safe) br...

Re: Forced induction from the fan shroud

Lets not forget, these engines where not ment to be placed in a bike frame in the first place! I'm convinced that the speed derived airflow is enough to keep the cilinder within limits. Maybe on the high side but that's ok for a diesel. And as I stated in another tread, getting rid of the fanblades ...

Thanks for the compliment sno bro. The 350 indeed goes like a maniac :mrgreen: . Even with the original span. It's a Duna span made almost completely out of aluminum. It weighs next to nothing.

Re: Greek Opposed Piston Diesel

If you can get an oil with good lubrication qualities wich is also combustable without producing smoke than 2 stoke will become widely accepted again. I'm not quite sure what burning lubrication oil has to do with anything. It may interest you to note that two-stroke diesels don't work in the same ...

Re: Tech Pictures of the HDT engine

I guess it wil be quite simmular to a common rail dieselpump. I think that's the way to go. A high pressure pump and a piezo injector on a one-cilinder. That would get the performance up and over gasoline levels.

Currently, the focus in engine development is mostly on 2 stroke. Just because its a better principle. The work temperature and fuel/air mixture need to improve. Smoking is caused by burning lubrication oil. If you can get an oil with good lubrication qualities wich is also combustable without produ...

Congratulations! Nicely done. Nice movie as well. However it seemed to me that however you tuned the engine up to 4500 RPM it didn't go near there. I have the feeling that if you would use a larger rear sprocket, it might just have some extra power to overcome wind resistance an maybe gain some extr...
