Abstract
The utility model discloses an internal-combustion engine cylinder pressure sensor of a metal ceramic heating element with an insulated lantern ring, which relates to an internal-combustion engine cylinder pressure sensor. The utility model aims to provide an internal-combustion engine cylinder pressure sensor of a metal ceramic heating element with an insulated lantern ring. The internal-combustion engine cylinder pressure sensor comprises an outer shell, a metal ceramic heating element, a heating element outer insulating layer, a film, a film fixing ring, a pressure sensor, a sensor ring and an insulated lantern ring, wherein the outer shell is arranged on an internal-combustion engine shell; the metal ceramic heating element is arranged in a central hole of the outer shell; the heating element outer insulating layer is arranged at the outer surface of the metal ceramic heating element; the central hole of the film is connected with the heating element outer insulating layer, and the outer edge of the film is arranged on the outer shell; the insulated lantern ring is arranged outside the end of the metal ceramic heating element; the sensor ring is connected between the outer shell and the insulated lantern ring; and the pressure sensor is arranged in the sensor ring. The internal-combustion engine cylinder pressure sensor is applied to an internal-combustion engine device for controlling fuel to emit by electron. The utility model has the advantage of that a shunt path between a heating element and the outer shell which are grounded can not form.
Description
Technical field
Relate to a kind of Cylinder Pressure of Internal Combustion Engine sensor.
Background technology
Prior art Cylinder Pressure of Internal Combustion Engine sensor comprises shell, electric heating element and pressure transducer; Electric heating element is cased, and cylinder enteroception inner pressure of air cylinder is stretched in its end; Shell is contained on the cylinder of internal-combustion engine wall; Pressure transducer is connected between shell and the electric heating element.The weak point of prior art is that pressure transducer is connected between electric heating element and the shell, constitutes the shunt access between the electric heating element and the earthing of casing, influences the operate as normal of electric heating element.
