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

Click For Summary

Discussion Overview

The discussion revolves around the search for devices that can inject an air-fuel mixture into a combustion chamber, as opposed to using conventional fuel injectors that only inject fuel. Participants explore the feasibility and alternatives to achieve this goal, touching on theoretical and practical aspects of engine operation.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses a need for a device that can inject an air-fuel mixture, questioning the limitations of conventional fuel injectors.
  • Another participant argues that using a conventional intake stroke is effective for introducing air and fuel into the engine, suggesting that the existing method works well.
  • A participant references a blog post about Honda's CVCC technology, implying a potential relevance to the discussion.
  • It is mentioned that some gas engines utilize port injection, which may accommodate air with fuel in suspension, but challenges exist for in-cylinder applications under conventional pressures.
  • A participant inquires about specific examples of injectors that could meet the original request, but the response indicates a lack of specific information.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best approach to inject an air-fuel mixture, with differing views on the effectiveness of conventional methods versus the need for alternative devices.

Contextual Notes

There are unresolved questions regarding the technical feasibility of injecting an air-fuel mixture, including the implications of engine pressures and the specific types of injectors that may be suitable.

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!
