Investigation into producer gas utilization in high performance natural gas engines
MetadataShow full item record
A wide range of fuels are used in industrial gas fueled engines including well-head gas, pipeline natural gas, producer gas, coal gas, digester gas, landfill gas, and liquefied petroleum gas. Many industrial gas fueled engines operate both at high power density for increased efficiency and at ultra-lean air-fuel ratios for low NOx emissions. These two conditions require that engine operation occurs in a narrow air-fuel ratio band between the limits of misfire and the initiation of knock. The ability to characterize these limits for a given fuel is essential for efficient and effective engine ...
