My 20 lb thrust PJ Engine with 32 Argus valves

[Rocket Man]

My 20 lb thrust Engine has 32 Argus valves. It starts easy on propane, gas, alcohol and different fuel mixtures. Gasoline produces more power than propane, 50/50 gas kerosene produces more power that 100% gasoline. 100% Methanol produces about 50% more power than gasoline. I am using fuel injection in this video with propane. Fuel injection also works fine with gasoline, alcohol and fuel mixes. I also experemented with a venturi and a needle valve it works excellent too. I can adjust the needle valve to 100% thrust for each fuel. Fuel injection is the best. I bought a digital scale to measure thrust but this scale is worthless it locks on a weight and stays there until it is reset. I returned to my old method let the engine lift a bucket of water off the bathroom scales. It was interesting to experement to see the thrust difference of fuels and different fuel mixtures. Methanol with 2% water produces more thrust than 100% methanol. I took about 10 videos but nothing turned out good I wanted to show the thurst readings on the digital scale. Engine starts very easy on low thrust the scale locked on 4 lbs of thrust then when I throttle it up to 20 lbs and 25 lbs the scale still reads 4 lbs. The old time spring type bathroom scale works the best. I thought I posted this video several months ago but I guess I never got around to it. My camera does not show the difference when I change fuels, I can start on propane then turn on gasoline then swap to methanol the different fuels make a noticable difference in sound and thrust but the video shows the sounds to be the same all the time. Camera must have some type of built in sound volume protection.

I built a 50 lb thrust engine that runs excellent. I used it to power a bicycle running on methanol it pushes that bike faster than I want to ride it. The bike speed-0-meter was reading 50 mph and I was holding the brake to keep from going any faster the wind in my eyes was blinding me. I want to get a video of this but I need my Sons help. I want him to drive along side and get a video of me picking up speed the reading on my bike speed-0-meter and his car speed-0-meter. Next time I need goggles.

I am building a 250 lb thrust engine. I don't do much work in the shop in the summer I would rather be hiking and camping.

I am getting the stuff together to build a 1000 lb thrust PJ engine. Nothing much is happening at the moment I hope to get back to work on my projects about November when the weather is bad and I become a prisoner in my work shop.
