I had a few free hours today so l decided to dedicate them to DOW. Or shuld l say makeing DOW better.
Warmed up the engine, the gasifier and set the throttle to about 3500 rpm on wood in neutral. Then l performed some tests.
First, l connected the original throttle body back (just the electric part) and played with different throtle positions vs rpm ups and downs (this it just the imaginary throtle, since l did not remove the twinflap). The main point of interest was timeing advance. But, it does look like l get the best timeing advance with the original TB disconnected completely (showing 73% throtle). This way l got 35° advance at 3500 rpm, but with the TB connected, only up to 25°.
The -40°c was still there, and no, l wasnt able to find air inntake temp. sensor. When that was cleared, l went to injectors leaking gasoline, causeing my big petrol consumotion.
I pulled out the injector fuse and the engine started to stumble, and dyed. Keep in mind it ran strong and constant on woidgas for about half a houtr. So, l went the other route, disscinnected the fuel line (just click-click) and the engine didnt eaven notice. So, my missing petrol theory is under questiin.
I added a fan today, this way l can save some startup petrol, will see where this takes me.
I allso wanted to try egr valve disconnected, to see if power increases, but forgot.
And in the end, a short video l wuld like to share with you guys, one l dont think l ever seen before on Youtube, the operateing near emoty gasifier hearth and its butyfull downburning flames:
