Title: Fuel economiser for IC engine - preheats fuel before it is mixed with combustion air
Inventor: FINZE SEN HELMUT
IPC: F02M31/16
Filed: 1975-08-27
Abstract: The device preheats the fuel before being mixed with the combustion air. The preheated fuel would have a greater volume as a consequent and therefore able to absorb more oxygen. The oxygen intake being colder than the preheated fuel would cause a finer atomisation than conventional carburation. The fuel could be fed through a spiral tube passing through the engine water cooling system. In the case of an air cooled engine the surplus heat would be similarly used. The heating would take place on the pressure side of the fuel lift pump to avoid the formation of air bubbles.
