Adapting spark-ignited engines for gaseous fuel operation

摘要

While gaseous-fueled spark-ignited engines continue to gain acceptance in a variety of industrial backup power systems, most are sourced ready to run on gasoline fuel, not dry gaseous fuel. The differences between these two fuel types are significant enough that generator manufacturers must extensively modify or purpose-design engines for use in backup power systems. As such, these manufacturers provide not only backup power expertise, but also considerable engine design expertise. Additionally, in spite of these modifications, gaseous-fueled backup power systems continue to be extremely cost-effective alternatives to diesel-fueled generators in applications below 150 kW.
