A better insight into the different response of the engine to the diverse injection mode is provided by the charts in Figure 4 as the relative air-to-fuel ratio is plotted for the six cylinders for the SP (red plots) and the MP (blue plots) configuration for WOT (solid lines) and part load operations (dashed lines).
Table 1 and Figure 7 show that C[O.sub.2] mass fraction has remained relatively unchanged as the air-to-fuel ratio increased.
Burners are monitored using CO/[O.sub.2] sensors to get the best air-to-fuel ratio for combustion optimization.
The system is designed to predict and provide the amount of fuel needed to keep the optimum air-to-fuel ratio of 14.1:1.
This refers to limits set by the Environmental Protection Agency on the amount of particulate matter emitted by wood-burning appliances that meet certain criteria (dealing with air-to-fuel ratio, firebox volume, burn rate, and weight).
In this way, the air-fuel mixture from the main chamber back feeds into the pre-chamber thereby detrimentally causing an unknown air-to-fuel ratio within the pre-chamber.
[40], [41], Cylinder composition estimation is extensively discussed in terms of air-to-fuel ratio control [42,43].
In eco mode, the 912 iS will operate close to Lambda 1, which is a stoichiometric 14.7 to 1 air-to-fuel ratio. Rotax was cagey on precise fuel scheduling, but allowed as how Lambda 1.3 (leaner) might be possible in some operating environments.
For the catalyst to perform its emission-reducing capabilities, the natural gas engine's lean-burn characteristics had to be altered to a stoichiometric air-to-fuel ratio.
Turbochargers for large-bore reciprocating engines no longer will represent merely a system add-on to increase the air-to-fuel ratio, but will play a major role as a controllable component that significantly reduces pollutant emissions and increases engine fuel efficiency.
By recirculating exhaust gases back into the combustion chamber, however, Mitsubishi uses the exhaust to reduce [NO.sub.x] Because the air-to-fuel ratio is so high, the exhaust gases, which normally hinder combustion, can be as much as 70 percent of the cylinder volume.
