ELECTRIC HEATER OF OIL IN INTERNAL COMBUSTION ENGINE Russian patent published in 1997 - IPC

FIELD: engine engineering. SUBSTANCE: electric heater has heating member secured in a holder and connected with power supply cable through a commutator positioned in the holder. The heating member is flexible and made up as a multi-conductor cable which is provided with the solid layer of carbon threads. The conductors at the end of the cable are striped. The cable is provided with a cylindrical shank with a tip made of dielectric material. The striped conductors are uniformly oriented along the surface of the shank closed with carbon threads and pressed together with them to the shank by clamp. The cable together with striped cords, threads, shank and clamp is enclosed by a dielectric heat resistance rubber shell that tightly abuts against the tip. EFFECT: enhanced efficiency. 5 cl, 4 dwg
