"Clean" Diesel

If GM (Ford or Chrysler) were to use a diesel engine with low or lower emissions they could try this method.

The outgoing (emission) gases (flowing upward) would be filtered through cylindrical screens. The innermost screen would have a larger mesh with the outermost screen being of the smallest mesh. As the emission gases pass upward through these combined screens, a cleansing liquid would flow downward on the outermost screen, where all the exhaust would finally end up, removing a goodly portion of the diesel emissions and ridding the diesel pollutant of that awful smell. This cleansing liquid would be recycleable - renewed and reused.

This possible emission control could make it feasible for a diesel motor to be used in any vehicle, being the smallest auto to the biggest truck.
