DIY Gas Jet Turbine Go Kart - Walk Talk & Start Up

A resonably in depth Talk & Walk around and eventual start up and run of my DIY Jet Turbine Go Kart. Please excuse my mistake when I stupidly say that Jet engines dont 'Squeeze' the air - of course they 'squeeze' the air !! The compressor wheel within the turbocharger see's to that! - What was I thinking of ?? Oh, AND the fact I refer to the OIL pump as a FUEL pump as well - what a chump Eh ! :)
Also, the tacho didn't seem to want to work correctly, It wouldn't read over 5000RPM for some reason - I need to look at it - Flat out the engine will be spinning at around 86000RPM - Idle is 22000RPM.
One day I will actually get to sit in and run this thing along a track! I cannot at the moment find one that will cater for such a thing here in the UK without taking it along to a 'run what you brung' type Drag Strip event.
Anyway, hope you enjoy the clip
Jim

PS - the metal gate frame was HOT to touch after we had finished :o)

PPS - The word I was looking for was - Stoichometric :)

Thanks Carl :)

wow. what a helpful blog and a great project. im putting alot of thought into building a jet turbine. im a commercial combustion engineer and was just wondering if you have ever analysed the combustion products?? if so what is the co/co2 ratio like? thanks for your help. pete.

[smogthemog]

@ ngn (Pete) - No I haven't done any CO/CO2 analysis. It works so I am happy with that :)

Actually, you DO get a squeeze stroke in an engine like this. The compressor does not suck air in. It creates a vaccuum in the front of the housing which allows air to enter the compressor and the compressor wheel squeezes the air....Aka compresses it. Air itself is not very volatile. and results in a slow burn. thats why it must be compressed before it burns or is ignited.

@ antiricer4u - and if you read the blurb that goes with the video you will see that I have corrected what I said. Thanks for your comment though.

@ xPRED - Yes mate, I do do a cool down with the leaf blower. On board propane is in the RH tank as you sit in the kart. It's in a proper tested Propane tank. No flash arrestors fitted, it dosen't need them. Propane tank - 12V solenoid Valve - rotary valve for the throttle then the propane injector. Hope this helps.

what is the inducer size on the compressor? what kind of thrust do you achieve?

[KaptainKoolz]

how fast is that thing? i am looking to do a similar project, but im considering using twin engines

[Mrcaffinebean]

so it goes like this right...

turn oil on

insert leaf blower

ignite fuel

wait a a bit until it self sustains

[wcavalieri10]

amazing video, if the throttle is controlled by the amount of fuel then wouldnt the turbine spin faster and faster until it self distructs? also what is a safe rpm to run a turbocharger at? is that just any old turbocharger?

[erjohnson227]

very good video my friend, i am looking into making one of these... the information from this video was very helpful :)

smog- 3 quick questions. first are you doing a cool down? if so, with the leaf blower? second, where is your on-board propane located? any type of flash arrester on the propane line? third, how did you rig the propane to a throttle assy? o.k. so that was like 5, sorry. Love your machine, great job.
