Abstract
A thermoelectric generating composite functioning apparatus used as a glow plug in a diesel engine has sintered semiconductor elements respectively formed in the shape of a bar of N-type and P-type thermoelectric semiconductor materials. The N-type and P-type semiconductor elements are provided oppositely with a gap between them, and their end portions are put in mutual contact to form a P-N junction. A low thermal conductivity insulator is filled in the interval between the N-type and the P-type semiconductor elements. The N-type and P-type semiconductor elements provided in the P-N junction state are contained through the insulator in a housing. Lead terminals connected to the N-type and P-type semiconductor elements are formed in the housing. The apparatus may provide heat to the combustion chamber, or generate electricity from the heat in the combustion chamber.
