| Definition | Current methods for controlling NOx emissions in motor vehicles include retardation of spark timing, increasing the air/fuel ratio, injecting water into the cylinders, decreasing the compression ratio, and recirculating exhaust gas. For stationary sources, one abatement method is to use a lower NOx producing fuel or to modify the combustion process by injecting steam into the combustion chamber. |
