摘要： When only smoke is generated, the sensor sensitivity is not substantially changed from the initial value. When both smoke and unburned HC are generated, the number of times the sensor sensitivity becomes lower than the initial value is increased. From these results, it can be understood that a deposit is formed in the presence of unburned HC and smoke existing simultaneously. The degree of reduction in sensor sensitivity becomes higher if the smoke concentration is increased when the unburned HC concentration condition is fixed. From this result, it can also be understood that while the coexistence of smoke and unburned HC is a prerequisite, unburned HC contributes largely to the formation of a deposit.
摘要翻译：当仅产生烟雾时，传感器灵敏度基本上不会从初始值改变。当产生烟和未燃烧的HC时，传感器灵敏度变得低于初始值的次数增加。从这些结果可以看出，在存在同时存在的未燃HC和烟的情况下形成沉积物。如果未燃烧的HC浓度条件固定，烟浓度增加，传感器灵敏度的降低程度就会变大。从这个结果可以看出，虽然烟雾和未燃烧的HC的共存是先决条件，但未燃HC在很大程度上有助于形成沉积物。

摘要： A combustion chamber pressure gauge for an internal combustion engine, comprising a housing tube, a plunger, which is movable in an axial direction in the housing tube under the effect of combustion chamber pressure against a restoring force, and comprising a seal, which is disposed between the plunger and the housing tube, and comprising a sensor for detecting an axial displacement of the plunger. The sensor is decoupled from thermally induced expansions or contractions of the housing tube, in that the sensor is attached to a carrier, which is suspended in the housing tube, and the plunger is movable relative to the carrier under the effect of combustion chamber pressure.

摘要： The invention relates to a method for supplying current to a glow plug in a running diesel engine after reaching the operating temperature thereof by a series of current pulses, wherein a piston of the engine carries out a work cycle comprising several strokes and the glow plug is supplied with current as a function of the strokes of the work cycle such that the electric current supplied in each work cycle is mainly supplied at a predetermined, steady stroke of the piston, wherein control time intervals that follow each other are defined, during which up to two switching processes can be triggered by a control device, by which the glow plug can be connected to a voltage source for creating a current pulse or can be disconnected from the voltage source for ending a current pulse. According to the invention, the control time intervals have a duration that can be varied by the control device as a function of the rotational speed of the engine.

摘要： A glow plug with a combustion pressure sensor is improved in airtightness between the same and a combustion chamber. The glow plug 100 includes a housing having a substantially tubular metallic shell extending in an axial direction and a substantially tubular cap member which is provided at the front end of the metallic shell, which is shorter in length along the axial direction than the metallic shell, and whose diameter decreases toward the front end thereof, a heater unit, a connecting member, and a pressure sensor. The cap member is formed of a material higher in tensile strength or yield strength than a material used to form the metallic shell, and the metallic shell is formed of a material higher in thermal expansion coefficient than that used to form the cap member.
