automixte system

 A system (devised by Henri Pieper, a Belgian) of driving automobiles employing a gasoline engine and an auxiliary reversible dynamo. When there is an excess of power the dynamo is driven by the engine so as to charge a small storage battery; when there is a deficiency of power the dynamo reverses and acts as an auxiliary motor. Sometimes called Pieper system.  [Webster 1913 Suppl.]
