  1. emission
    a substance that is released
    There are four basic types of vehicle exhaust emissions: hydrocarbons (from unburned fuel or fuel evaporation), carbon monoxide (from partially burned fuel), oxides of nitrogen (from extremely high temperatures during combustion), and particulates (solid pieces of carbon soot and fuel additives).
  2. quench
    put out, as of fires, flames, or lights
    A quench area is produced when the engine pistons move too close to the cylinder head; this closeness quenches combustion and increases emissions due to unburned fuel.
