Normal Air Fuel Ratio At Idle at Lisa Mccoy blog

Normal Air Fuel Ratio At Idle. Anything that has more air (or less fuel) than this is considered lean, or a lambda of greater than 1.0. The ideal ratio is generally around 14.7:1. This is largely dependent on the camshaft design, the valve overlap, and the ability of the injectors to deliver very short pulse width injections (somewhat difficult with large injectors), as well as the injector flow balance. If you richen it to where it idles best you'd find out it's in the low 13's if. That’s 14.7 parts air for every 1 part of fuel. I run at ~14.7:1 at idle (when hot),. You really can't use a afr meter at idle on a race engine. In many cases, the idle stability will determine where we set the idle air fuel ratio. To optimize the combustion process, certain quantities of fuel and air need to be supplied in the combustion chamber. This the amount of air required for the complete combustion of the fuel, known as the stoichiometric mixture or lambda 1.0. I have increased the primary idle air bleed size, and decreased both sets of high speed bleeds.
