摘要： A flexible barium titanate ceramic PTC heater for use in, for example, an intake pipe of an internal combustion engine to heat the air-fuel gas mixture is formed as a thin disc-shaped ceramic sheet constituted by a plurality of individual coplanar ceramic segments having interior edges positioned in spaced side-by-side relationship. The juxtaposed edges of the ceramic segments are united to each other by a flexible, heat-resistant, electrically non-conductive rubber band disposed in the space between the segments and bonded thereto by an electrically non-conductive adhesive to form the segments into a thin disc-shaped sheet which can be flexed without causing flexing of any of the individual segments. The ceramic heater is positioned in a metallic casing with one planar face thereof bonded to the inner surface of the casing by an electrically conductive adhesive. A stainless steel wool cushioning member engages the other planar face of the ceramic heater to support the heater in the metallic casing.

摘要： A fuel evaporator for an internal combustion engine is comprised of a metallic casing which is composed of a heating plate portion and a supporting portion projecting from the outer periphery of the heating plate portion downward, a heating element fixed to the heating plate portion within the casing, an insulating and adiabatic covering member which covers the supporting portion and an electrically connecting means which connects the heating element and a battery.The supporting portion of the casing is inserted in a hole formed in an intake pipe so that the heating plate portion is exposed therewithin.Since the supporting portion of the casing is covered with the insulating and adiabatic covering member, very little of the heat of the heating element is dissipated from the supporting portion into the intake pipe.By forming the supporting portion into a plurality of strip shaped legs, the heat escaping therefrom can be further reduced.

摘要： A fuel evaporator comprises a metal member composed of a pipe portion and a flange portion, a heating element made of PTC ceramic, which is closely adhered to the metal member and an electric connector for electrically connecting the heating element and an electric power source. The metal member is supported by an insulating member which is interposed between an air-fuel passage and an intake manifold. The fuel film flow flowing downwards along the wall of the air-fuel passage is received by the flange portion of the metal member and is heated by the heat transmitted from the heating element. Consequently, unvaporized fuel is effectively evaporated.

摘要： An internal combustion engine fuel injection system includes a temperature sensor for detecting the temperature of the fuel or cooling water in the engine. When the detected temperature is higher than a given value, e.g., 50.degree. C., a pressure regulator for controlling the pressure of fuel supplied to a fuel injection valve is controlled so as to increase the fuel pressure irrespective of the intake pipe negative pressure and thereby increase the quantity of fuel supplied to the engine. In the case of an electronically controlled fuel injection control system, a predetermined correction quantity corresponding to the detected temperature from the temperature sensor is added to the basic fuel injection quantity calculated in accordance with given operating parameters of the engine, thereby increasing the quantity of fuel supplied to the engine.
