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!

Carburetor CFM A Holley Carb rated at 500 cfm 2 barrel carb has venturi diameter of 1.3/8". There are 2 barrel carbs with 600 cfm and have 1.45 diameter venturi. Looking at the area the 1.378 bore has 5.9 sq. Inch area. The 1.45 dia. has 6.6 sq. inch. 5.9 - 6.6 = 0.70 sq. inch difference. Keeping the 500 cfm carb in place, if I can introduce 0.7 sq inch more area in the intake manifold, will I have the same potential horsepower as a 600 cfm carb provide? Assume I can change jetting to...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
