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.

The advantage of the coupling was the opportunity to produce a central cloud of nearly stoichiometric mixture at the center of the combustion chamber, with a surrounding cushion of air which could then be high-energy bulk ignited by multiple jets of hot reacting gases and rapidly and completely burned with reduced heat losses.
The peak burned gas temperature of the stoichiometric mixture is higher than the peak burned gas temperature of the lean and rich mixtures, for each of the RGF cases.
The significant weight losses of In : Ga : Zn (1:1:1) stoichiometric mixture at the range from 100[degrees]C to 250[degrees]C indicated the formation of metal-oxide bond and decomposition of the acetylacetonate ligands should occur with the rising of temperature.
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.
The optimum for the flame holding is reached near the J number of 10, when the gas mixture with the mixture fraction of 0.89 (i.e., the stoichiometric mixture of [H.sub.2] and [O.sub.2]) is involved in the recirculation.
Stoichiometric mixture of [Eu.sub.2][O.sub.3], Co, and BaC[O.sub.3] was dissolved in diluted (1: 3) nitric acid.
This stoichiometric mixture was taken in a re-crystallized alumina crucible and heated at 1000[degrees]C for 10 h to obtain phase pure CCTO (9).
The effects of ball milling parameters, namely, the ball-to-powder mass ratio and milling speed, on the synthesis of ([K.sub.0.5][Na.sub.0.5])Nb[O.sub.3] nanopowders by high-energy ball milling method from a stoichiometric mixture containing [Na.sub.2]C[O.sub.3], [K.sub.2]C[O.sub.3], and [Nb.sub.2][O.sub.5] were investigated in this paper.
According to Zhang et al., pure phase of [Zn.sub.3][V.sub.2][O.sub.8] is formed from the stoichiometric mixture of high purity ZnO and [V.sub.2][O.sub.5] heated above 700[degrees]C for 12 h.
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] = 1.4-1.6).
2.3-3.5 MJ/[m.sup.3] of stoichiometric mixture composition for the examined types of different diesel biofuels including mineral one prove the fact that its use does not have a big influence on diesel engine power indices, despite of much lower values of alcohols [H.sub.um] and [H.sub.uv].
