Al Navecky Jr Posted July 7, 2006 Share Posted July 7, 2006 I am having a brain fart here and can not remember which is fuel and which is air in the ratio 14.7:1. Which way is lean, which way is rich? Thanks Link to comment
smiller Posted July 7, 2006 Share Posted July 7, 2006 14.7 is air, lower number is richer, higher is leaner. Link to comment
ShovelStrokeEd Posted July 7, 2006 Share Posted July 7, 2006 The answer lies in the terminology. It is air/fuel ratio. 14.7 lbs of air to 1 lb of fuel, in this case. Richer would be 12 lbs of air to one lb of fuel. Actually the units don't much matter just understand that they represent mass. I'm actually going to have to go back and do some reading on Stoichimoetry to see if it refers to lbs of air or lbs of oxygen, but, I think it is air when refering to internal combustion engines. Mitch would know this stuff off hand but, us older guys need to research. After some research a very clear explanation can be found Wikipedia Link to comment
