stoichiometric mixture

stoichiometric mixture

The ratio of fuel to air, in which both ingredients can be consumed completely in the chemical reaction. The ratio is about 1 lb of gasoline to 15 lb of air. See air-fuel mixture ratio.

Typically, the 2-S ICE operates in a condition of poor stoichiometric mixture ([lambda] < 1), which leads to incomplete combustion and emissions in significant amounts in the exhaustion gases, usually ten times higher compared with a 4-S ICE.
In the tests, the engine was operated with the stoichiometric mixture and the engine-out coolant temperature was controlled at 90[degrees]C.

Similarly nitro-methane, when added as a fuel component, is reported to boost engine output because of its high specific heating value (the amount of heat that can be released per unit mass of air under stoichiometric mixture conditions) which is almost twice that of methanol (refer to Table 1).
The results obtained of differential pressure carburetor from the engine test run conditions shows that the controller has maintained stoichiometric mixture at different constant load conditions and at load throw off conditions.
There are 2 ways of preparing the mixture for combustion: the preparing of a stoichiometric mixture of gas and air ([lambda] = 1) and the preparing of a weaker mixture of gas and air ([lambda]>1, [lambda] = 1.
