However, at high loads ( i . e . high fuel / air ratios ), knocking is a possibility even in HCCI.
12.
In ultra-light cigarettes, the filter s perforations are larger, and in theory, these larger holes produce an even smaller smoke to air ratio.
13.
The fuel / air ratio is determined by the ratio of the diameter of the orifice to the diameter of the mixing tube.
14.
The experimenters also discovered that the smog in L . A . caused varnish to form in the automobiles carburetors, changing the fuel-to-air ratio.
15.
Alternate methods based on reducing the ullage fuel-air ratio to below the LFL or increasing the fuel-air ratio to above the UFL have also been proposed.
16.
Glow engines generally have to be run slightly rich with a higher fuel / air ratio than is ideal in order to keep the engine cool.
17.
Alternate methods based on reducing the ullage fuel-air ratio to below the LFL or increasing the fuel-air ratio to above the UFL have also been proposed.
18.
"' Tissue-to-air ratio "'( TAR ) is a term used in radiotherapy treatment planning to help calculate absorbed dose to water in conditions other than those directly measured.
19.
Cutting off the fuel supply causes the fuel-air ratio to become greater than sixteen to one, which is then too lean for combustion to take place, stopping the engine.
20.
The application of gas / combustion air ratio devices generates the greatest part of the energy saving, which is provided by the modern condensing boilers, not the condensation technology itself!
