摘要： A sintered ceramic heater, particularly a heater for a glow plug of a diesel engine, includes a sintered ceramic heater, which generates heat upon receiving an electric current, supported by an electrically insulating sintered ceramic body. The heater element includes a U-shaped cross-section outer portion integrally sintered with and covering a central portion. Each portion is formed of a sintered ceramic body of a mixture of electrically conductive ceramic powder having an average diameter of not more than 2 .mu.m and selected from the group consisting of MoSi.sub.2, WSi.sub.2, TiB.sub.2 and TiC, and 35-75 mol % of electrically insulating ceramic powder, e.g., Si.sub.3 N.sub.4. The central and outer portions have the same composition. However, in the central portion the average particle diameter of the conductive ceramic powder is equal to or larger than that of the insulating ceramic powder, whereas in the outer portion the average particle diameter of the conductive ceramic powder is not more than half that of the insulating ceramic powder. The specific resistance of the central portion is not less than 1.7 times as large as that of the outer portion so that the heat is generated by current flow through the outer portion of the ceramic heater.

摘要： An engine preheating apparatus in which an actuation circuit for a glow plug mounted in the engine is provided with a starting resistor of barium titanate of which the resistance value abruptly increases at a specific temperature, and a normal-operation resistor connected in parallel to the starting resistor. When the starting resistor is low in temperature and hence has a small resistance value, a large current is supplied to the glow plug, whereas when the starting resistor is high in temperature and therefore has a high resistance, a comparatively small current is supplied to the glow plug through the normal-operation resistor. The starting resistor is comprised of plural resistor elements of barium titanate as a main component and plural electrode plates alternately pressed one on each other. Each of the electrode plates is in pressure contact with each of heat radiators, so that the heat generated by the resistor elements is radiated from the radiators through the electrode plates. The time constant of the resistor elements is determined by the shape of that portion of the electrode plate which is connected to the radiator.
