Quesiton : The air to gas ratio is maintained by a ________
Answer: modulating motor and linkage air damper butterfly valve (all of the above)
The air to gas ratio is maintained by a ________ A 'Stoichiometric' AFR has the correct amount of air and fuel to produce a chemically complete combustion event. For gasoline engines the stoichiometric A/F ratio is 14.7:1 which means 14.7 parts of air to one part of fuel. The stoichiometric AFR depends on fuel type-- for alcohol it is 6.4:1 and 14.5:1 for diesel. How can the answer be improved? As long as the air/fuel ratio adjustments are modest the exhaust gas flow rate will track the combustion air feed rate quite closely. Thus a properly implemented differential pressure measurement is a “fast cheap and easy” method for inferring combustion air … A 'Stoichiometric' AFR has the correct amount of air and fuel to produce a chemically complete combustion event. For gasoline engines the stoichiometric A/F ratio is 14.7:1 which means 14.7 parts of air to one part of fuel. Air-Fuel Ratio (AFR) is the ratio of air - to-fuel present in a combustion process such as in an internal combustion engine or industrial furnace. Below lists three common AFR schemes: REMVue®’s patented air-fuel ratio technology has been utilized in retrofitting natural gas fueled engines. Intro to Air-Fuel Ratio Control A.J.
