Abstract

FIELD: engine engineering. SUBSTANCE: spark plug has housing, central electrode mounted inside the housing and electrically insulated from it, and heater formed of a substrate made of aluminum oxide and electric heating unit made of niobium and formed of a metallic film that is positioned on the substrate. One end of the heating unit is in electric contact with the housing. The other end is in electric contact with the central electrode. EFFECT: enhanced reliability.

Изобретение относится к двигателестроению, в частности к устройствам зажигания с помощью нагреваемых тел, предназначенных для облегчения запуска двигателей внутреннего сгорания, преимущественно дизельного двигателя. Запальная свеча содержит корпус, центральный электрод, расположенный в корпусе и электрически изолированный от него, и нагреватель, выполненный из подложки (материал - оксид алюминия) и электрического нагревательного элемента (материал - ниобий), выполненный в виде металлической пленки, расположенного на поверхности подложки, при этом один конец нагревательного элемента находится в электрическом контакте с корпусом, а другой - с центральным электродом. Предложенная запальная свеча обладает скоростным нагревом, является термостойкой, имеет увеличенный срок службы.The invention relates to engine building, in particular to ignition devices using heated bodies, designed to facilitate the starting of internal combustion engines, mainly a diesel engine. The glow plug contains a housing, a central electrode located in the housing and electrically isolated from it, and a heater made of a substrate (material is aluminum oxide) and an electric heating element (material is niobium) made in the form of a metal film located on the surface of the substrate, while one end of the heating element is in electrical contact with the housing, and the other with the Central electrode. The proposed glow plug has high-speed heating, is heat-resistant, has an extended service life.
