Daga IV - 4 stroke IC engine

[iszczyg]

Hi,
I have just finished my fourth project: 4 stroke internal combustion engine based on Jan Ridders plans.

I have finished the engine in the beginning of this year, but since I've made a lot of mistakes, I had many problems with starting the machine. Finally, it is finished and works fine. I'm going to capture the engine operation with high speed camera.

Jan, thank you for the advices!

Best regards
Irek

Congratulations Irek,
It looks like you have the problems sorted out quite well. The engine starts and runs fine. I would think that this particular engine was quite a challenge for your first I.C. engine.

Looks great, runs great and watching the combustion is extremely cool. Congrats on a job well done.

Nice engine!
Can you tell me about your ignition system. I'm building jan Ridders 4-stroke with rotating valve and don't know anything about the ignition system.

Thanks all for the kind words!
The diagram of the ignition system is shown in the Jan Ridders page. It bases on the electronic gas lighter. I have noticed, that it works better with the 2V supply, so I have used two AA rechargeable batteries (1.2V each) with 1.2 Ohm/2W resistor.
