Fragmented combustion in a ICE is the reason why there is CO, HC,02,NOX left after combustion. I built a fragmented to Supersonic Injector for high speed combustion. Ran a big V8 engine for 20 minutes with it in garage with door shut. Any CO I'd be dead right now. Don't try this at home!! Over on engine tips forum they say 0% humidity is when you get most power. Can't find info on that. Do you have info on that? Last edited by maxc; 19-02-2013 at 03:24 PM. Reason: wrong terms |

Re: NACA study 531
I only just looking into this after reading your link.
Now I have to further research to get into greater details on this to form some some basic insight of this concept. Basically deflagration has to be induced rather a natural combustion process. In your case, steam is used to initiate this?

ICE? Please explain

I don't use steam in my pre-burn fuel system. Some steam is created in the fuel heating process. Last edited by maxc; 18-02-2013 at 02:29 PM. Reason: grammer |

Re: NACA study 531
I guess the NACA paper is focused on oxidantion of CO in a environment with steam.
Putting this study in practice in an ICE, CO percentage will be less but HC emissions is higher.

Only the water vapor level is different. So water displaces 02 in test cylinder. But flame moves faster. Something too ponder? |

Re: NACA study 531
One thing I've found with steam injection with carbed engine is that the HC's go down. I tested it with 4gas analyzer. Steam helps vaporize fuel on its way too combustion chamber. I don't have the 4gas analyzer now too show you that.

Re: NACA study 531
I just wonder the amount of system introduced was only a fraction of the products of combustion, namely CO2 and H2O.
Have you tried to work out this ratio? I will be very interested.

Re: NACA study 531
It was a 2.3 liter pinto engine at idle the water flow rate was about 2cc per minute. Don't know what the steam temp was about 450f 500f?
