ABSTRACT:
A power source has at least one combustion chamber, an exhaust system fluidly connected to the at least one combustion chamber and configured to receive an exhaust-gas stream, and a fuel source configured to supply fuel to the at least one combustion chamber. The power source also has an additive supply device configured to supply an ethanol additive to the at least one combustion chamber; and a selective reduction catalyst system catalyst fluidly connected to the exhaust system and configured to receive the exhaust-gas stream.
