• Cummins Engine Co. Ltd, has revealed that its parent Cummins company, of Columbus, Indiana, USA has reached an agreement with Filteron International Inc. of Dallas, for Cummins to acquire worldwide manufacturing and marketing rights to apply a new concept in pollutant filter systems to diesel engines.
The system will be made and marketed by Cummins' Fleetguard division in Tennessee, and a marketable product is not expected before 1972. The Filteron system uses an electrical process to remove sub-micron-sized particles from the air stream and is claimed to be more efficient than any other known process. Cummins, which has been working for some time on developments intended to produce engines with no visible exhaust smoke, is enthusiastic about the possibilities of Filteron but feels that it requires intensive development in order to adapt it successfully for use with diesel engines.
