| Spark ignited reciprocating internal combustion engines that run on gasoline, liquefied natural gas (LNG), compressed natural gas (CNG), liquid petroleum gas (LPG/propane), digester or landfill gas fuels are used widely for gas compression, power generation, pumping, emergency back-up and many other purposes. They are also a significant source of criteria gases and toxic air contaminants. This course covers spark ignited reciprocating engine operating theory, emission control methods and technologies including after-treatment devices (Oxidation, 3-way Catalysts, Selective Catalytic Reduction (SCR)), two-stroke/four stroke cycles, rich-burn/lean-burn engines, regulations, and inspection techniques. Air quality inspectors, engine operators, and environmental professionals will find this information valuable in conducting inspections, minimizing emissions, and staying in compliance with air pollution regulations. |
