Running a car on fuel & fuel vapour. More power & mpg
Discussion
So I have this 92 landcruiser. Its a really nice truck.
Its a real juggernaut with impressive acceleration for its size. Its rated 11/12 mpgs but I've tweaked it so much I get 15 to 16mpgs. When fuel was still 143/l 8k worth of fuel takes me 388km which is quite impressive for an I6. First I adjust the fuel pressure regulator all the way and advanced the timing. I could really advance the timing to do 0 to 60 in 9 seconds and oem states 13sec but when I do I get some pinging so had to slowpoke it. People keep judging the truck by its size asking if it doesn't consume fuel. I told em not as u expect.
So some weeks back I decided to take out the EGR valve cuz it was kind of stuck open and the temp jumps whenever I do some hard acceleration. So i took it out and it has been OK ever since. Acceleration and mpg got up to 17 which is cool with the EGR out.
I did an airfilter element wash and let the element dry under the sun. After that I fixed it back into the housing and started up my truck. Upon movement the acceleration was so super im sure I could do 0 to 60 in 7 seconds. Quite quick even I couldn't believe. Out of curiosity Turned off my truck and turn it back on. Boost was gone. I was curious. Then I did a lil research. I came across a channel THE VAPOUR KID on you tube, did a prototype setup and I got really good mpgs and with aggressive accelerations + ac. Though my set up was temporary. When all fuel has been vapourized truck became normal. I repeated this few times with great mpg gains.
My main point
Cuz im curious. Can I introduce Lpg in very little quantity to one of the vacuum lines and engine still running of fuel? Cuz the reason for my mpg gain is my vehicle's ECU thinks it's running rich and cuts off the pulses to the injectors. Thereby saving a lot of fuel. So im just wondering if fuel and propane could work in the same combustion chamber.
Note fuel injectors spray fuel as gas and propane has a better air fuel ratio as its already in gas state.
I've already thought about the regulator and the electric shutoff valve and flash back arrester.
Whats your opinion. Let me know. Cuz a 3kg Lpg would carry me for months and I believe if the mix is suitable I could push my mpgs up to 20/22. The fuel vapour worked superb

Have you thought this bit through? Why does the ECU think the engine is running rich?Am I being taken for a mug by replying?

Lamda sensor regulates that. The FPR is regulated to really lean. There are 2 regulators on the fuel rail. Incoming and outgoing the outgoing(return line) is almost fully open. Thereby fuel passes in and out the fuel rail without any restrictions. Whenever I cut out the fuel from the bottle, it runs like its about to die till it balances out after some revs. Am I being taken for a mug by replying?

2 regs on the rail, but you have a fuel regulator set to lean, then the fuel isn't passing without any restrictions.My advice: add a supercharger made from your girlfriends hairdryer and your pet hamsters wheel. Wire into the battery for an extra 450 bhp through the wheels.
So just like the vapour kid you filled a container with petrol, stuck in a wick and fed the resulting vapour into the engine.
What could possibly go wrong?

Anyway, it's a very old concept called a wicking carburetor, patented but abandoned a long time ago.

Love the fact you are using a plastic bottle containing fuel in the engine bay where a lot of heat is produced and then in the video you are worried about keeping your distance from this bottle as it contains fuel and you are holding a mobile phone!

Also remember running a engine lean will cause a lot of damage to it over time due to the excess heat produced
Valve damage is common as well as catalyst (allthrough I don't that's an issue for you)
tes but he's saving money on fuel with his Heath Robinson contraption.Valve damage is common as well as catalyst (allthrough I don't that's an issue for you)

As far as I know its impossible for a mobile phone to ignite even fuel vapour, let alone fuel in a container.Edited by Saleen836 on Sunday 8th November 19:31
