In one example, a controller may adjust a first phase voltage coupled to the glow plug in relation to a parameter associated with engine start time, and couple a lower second phase voltage to the glow plug in order to control the cylinder temperature and thereby the engine start time. In one particular example, the reduced second phase voltage allows the operating cycle push phase to be extended, which increases glow plug durability and further allows for the useful life of the glow plug to be extended. | 11-20-2014 |
20140338626 | ENHANCED GLOW PLUG CONTROL - Methods for controlling a glow plug temperature in a diesel engine in response to one or more past operating conditions related to glow plug aging are described. Thereby, the glow plug life calculator of the present disclosure may be useful for indicating degradation of the glow plug in order to prolong the useful life while increasing glow plug durability. In one example, a first phase voltage is reduced in relation to an engine parameter associated with engine start time in order to allow the life of the glow plug to be prolonged while maintaining engine start time at an acceptable level. | 11-20-2014 |

20140373800 | CERAMIC GLOW PLUG - A ceramic glow plug includes a ceramic heater; a tubular sleeve which holds the outer circumference of the ceramic heater with a front end portion thereof protruding from the front end of the sleeve; and a tubular housing which surrounds a rear end portion of the ceramic heater and has a mounting portion for mounting the housing. The sleeve has a small-diameter portion which is accommodated in a front end portion of the housing and has an outer diameter smaller than the inner diameter of the front end portion of the housing, and a large-diameter portion which is connected to the small-diameter portion, disposed frontward of the front end portion of the housing, and has a diameter larger than the inner diameter of the front end portion of the housing. The front end portion of the housing is welded to the large-diameter portion. | 12-25-2014 |
20150013633 | PRESSURE MEASURING GLOW PLUG - A pressure measuring glow plug includes: a housing in which a heating pin for igniting a combustion mixture of an internal combustion engine and a pressure measuring unit for recording a combustion chamber pressure of the internal combustion engine are situated. The heating pin has a glow current contact for an electric heating element. At the end of the heating pin facing away from the combustion chamber, a pressure transmitting element is fastened, which transmits the combustion chamber pressure acting on the heating pin to the pressure measuring unit. The pressure transmitting element is sleeve-shaped and forms an accommodation space for the glow current contact of the heating element. | 01-15-2015 |
20150047592 | GLOW PLUG - A glow plug includes a cylindrical housing, a rod-shaped heater, a membrane portion, and a pressure sensor. The cylindrical housing extends along an axial direction. The rod-shaped heater extending along the axial direction is displaced along the axial direction and has one end portion disposed within the housing, and an other end portion which is exposed from the housing. The membrane portion connects together the heater and the housing and has a multi-layer construction which has a first layer and a second layer of which at least part is positioned nearer to the other end portion in the axial direction of the heater than the first layer. The pressure sensor measures a pressure within a combustion chamber in which the other end portion is disposed by making use of a displacement of the heater. A thickness of the second layer is larger than a thickness of the first layer. | 02-19-2015 |
20150075473 | GLOW PLUG AND METHOD FOR MANUFACTURING SAME - A glow plug includes a cylindrical housing having an axial hole and provided with a screw portion, and a heater member which is inserted into the axial hole in a state where at least a front end portion thereof projects from a front end of the housing. The housing includes a pressure contact portion brought into pressure contact with a seat surface of an internal combustion engine when the screw portion is screwed into a mounting hole of the internal combustion engine, and a cylindrical front-end-side body portion provided between the pressure contact portion and the screw portion. The front-end-side body portion includes a holding portion which holds the heater member directly or indirectly at an inner circumference thereof, and the holding portion has a smallest outer diameter in the front-end-side body portion. | 03-19-2015 |

20150114333 | GLOW PLUG - Described is a glow plug with a glow pencil that comprises a forward end with a glow tip and a rearward end, a housing in which the rearward end of the glow pencil is arranged and in relation to which the glow pencil is movable in its longitudinal direction, and a bellows that is connected to the housing and the glow pencil. According to this disclosure, it is provided that a forward end of the bellows is attached to the housing and a rearward end of the bellows is attached to the glow pencil. | 04-30-2015 |
20150136054 | Pressure-Measuring Glow Plug Device - A pressure-measuring glow plug device includes a module housing, a glow plug configured to ignite a combustion mixture in a combustion chamber of an internal combustion engine, and a pressure-measuring device. The pressure-measuring device has a pressure sensor configured to detect the pressure in the combustion chamber. The glow plug is connected to the module housing by a flexurally elastic membrane. The force acting on the glow plug in the combustion chamber is transferred to the pressure sensor, which is supported on a supporting element by a preloading force. The supporting element is fastened rigidly to the module housing by a sensor housing. The glow plug device further includes a separate loading sleeve that is connected at one end to the pressure-transferring piece and at the other end to the supporting element. The loading sleeve is configured to apply the preloading force for the pressure sensor. | 05-21-2015 |
