Devices that can inject air-fuel mixture into the combustion chamber

AI Thread Summary
Devices that can inject an air-fuel mixture into the combustion chamber are not commonly available, as traditional fuel injectors are designed specifically for fuel. The discussion highlights the effectiveness of conventional intake strokes in managing air and fuel delivery. Some gas engines utilize port injection, which can handle air with fuel in suspension, but challenges remain for in-cylinder applications due to pressure constraints. The conversation suggests that while alternatives exist, they may not be suitable for typical engine conditions. Overall, the feasibility of injecting a combined air-fuel mixture remains complex and requires careful consideration of engine design.

hey,
I need all the help i can get on this one... can u guys tell me if there is any device that can be used instead of an ordinary fuel injector since i want it to be able to inject an air-fuel mixture. since the normal injector can't inject air i desperately need another device.

please do help!

Pretty hard to inject fuel and air at the same time considering the large volume of air needed by the engine. What's wrong with using a conventional intake stroke? That's exactly what it does and it seems to work very, very well!
 
Some gas engines use port injection; these injectors should be able to cope with air with fuel in suspension. For use in-cylinder you are going to struggle if you're planning to use 'conventional' cylinder pressures.
 
Do you have any examples of the injectors that you're thinking of, brewnog?
 
None that I should talk about, sorry. They're out there though!
 

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
