Abstract | NREL and the South Coast Air Quality Management District (AQMD) through separate agreements are funding a program with Mack Trucks Inc. to develop the next generation heavy-duty natural gas engine to be installed in a refuse hauler. Mack and Southwest Research Institute developed the E7G 12-liter lean burn natural gas engine to operate with stoichiometric (chemically correct) combustion and cooled exhaust gas recirculation (EGR). This engine was coupled to a three-way catalyst for reducing emissions. The objective of the project is to develop a natural gas engine with nitrogen oxide (NOx) and particulate matter (PM) emissions of 0.5 g/bhp-hr and 0.01 g/bhp-hr respectively with the use of a three-way catalyst. |
