Lei LIU,Zhi-jun LI,Hong-yang ZHANG,Qing CHANG,Bo-xi SHEN.Effect of rich air/fuel ratio and temperature on NO_x desorption of lean NO_x trap[J]. Journal of Zhejiang University-Science A(Applied Physics & Engineering).2013(11)Effect of rich air/fuel ratio and temperature on NO_x ...
The results illuminated that, the CO emissions drop sharply when air/fuel mixture changed from rich to lean. Particularly, at full load the CO emission decreases by about 4 times when λ changed from 0.85 to 1.1, and it keeps decreasing to only about one-tenth at λ = 1.2. Besides,...
Rich Condition Under the condition in which the air-fuel ratio of the exhaust gas is adjusted to be rich, NOx adsorbed on the lower layer under the first lean condition described above is converted to ammonia (Formula 2) by the reaction with the hydrogen generated from the water gas shift...
Conversely, the CH injection strategy leads to a lean mixture inside the prechamber at 7500 rpm and full load and a rich mixture at partial load due to a poor diffusion of liquid fuel in the cylinder. It is worth noting that the equivalence ratio trends of the PN8 geometry are more ...
PURPOSE:To output stable air-fuel control signals being unaffected by temperatures and perform good feedback control of air-fuel ratio by generating definite control voltages respectively on the rich side and lean side atmospheres. CONSTITUTION:Two standard side electrode layers 12A and 12B or two me...

An air/fuel ratio detector capable of producing an unambiguous output for both fuel-rich and fuel-lean regions. A solid-electrolyte oxygen-concentration-difference-actuated electrochemical cell sensor
Therefore, this A/F ratio sensor cannot be used for the purposes of A/F ratio control unless it is known definitely whether the combustor is operating in the fuel-lean or fuel-rich region. According to one method that has been proposed for meeting this need, the atmospheric air is ...
The results confirm that the dopant can preserve most of the Pd species in PdO even under the rich conditions. The results also suggest that both metallic Pd and PdO can act as the active sites for methane oxidation under much richer conditions, and that under lean conditions, PdO instead ...
aThe direct injection of fuel is what is responsible for the heterogeneously mixed air and fuel which forms local areas of both lean and rich mixtures. 燃料的直接射入是什么负责对形成两个精瘦和富有的混合物地方区域的异种地被混合的空气和燃料。[translate]...
