PROBLEM TO BE SOLVED: To solve a problem that an air/fuel ratio is kept in a lean condition in which the final fuel injection quantity cannot reach an aiming fuel injection quantity even by raising a feed-back correction value to a limit in the case an environment change detecting means ge...
The oxygen content of the exhaust gas, oxygen intake into the motor and the air/fuel ratio are measured to give the fuel/air ratio in the stoichiometric conditions of the combustion equation. To estimate the fuel/air ratio used by an internal combustion motor, with exhaust gas recirculation, ...
Closed-loop control of air-fuel ratio (AFR) can ensure a stable fuel feeding. The AFR control system adjusts the injected fuel in real time according to the feedback parameters in order to make the AFR value maintained at stoichiometric value (generally is 14.7), which can keep the three-...
While thermodynamic analysis suggests that a CH4/CO2 ratio of 1:2 at 800°C would be sufficient to avoid carbon deposition, experimental results suggested gradual deactivation of the Ni–anode catalyst in terms of increased ohmic resistance and activation polarization, which should be attributed to ...
For optimal methanol synthesis, the early hydrogen concentration of the syngas is usually very low. Equation (3) shows the water–gas shift reaction (WGSR), which is used to reduce the carbon monoxide concentration and increase hydrogen share, producing carbon dioxide and hydrogen from water and...
The numerical results were compared to actual experimental data from the literature, and they agreed well with the experiment. Taking the fuel/air ratio and Mach number as the optimization conditions, the initial size of the combustor could be obtained. On the basis of an optimized combustor, ...
Furthermore, it has been found that there is an optimal steam-fuel ratio (the value is 1.0 for B35), which facilitates the conversion of combustible components in the primary combustion products from a gas–solid state to a pure gaseous phase. Simultaneously, the temperature of combustion ...
CO and H2 were the fuel gases generated by IPA solution in the moving bed reactor prior to combustion with oxygen carriers. The yields of fuel gas generated from IPA solution were determined to modify the equation of oxygen carrier-to-fuel ratio for moving bed operation. The IPA conversion ...
Finally, by using the fuel/air ratio equation described above, it is possible to estimate the fuel/air ratio measured from MT and Mair: λ = M gazB · PCO M air · ( 1 + PCO ) + M gazB · PCO = 1 - M air M T ( 7 ) It is deduced: Mair=(1−λ)MT. By using notat...
An apparatus for controlling the air-fuel ratio of an air-fuel mixture to be supplied into a combustion chamber of an internal combustion engine comprises a passage bypassing a carburetor and a thrott
