| 20100031911 | DEVICE FOR STARTING AN INTERNAL COMBUSTION ENGINE, PARTICULARLY A DIESEL ENGINE - A method and a device for starting a diesel engine with no heater plugs, comprising pistons and cylinders defining combustion chambers into which gases intended to participate in combustion are admitted, in which method a strategy is adopted whereby the gases present in the chambers are heated up in such a way as to raise them to a minimum temperature within the entire volume defined by the chambers when the pistons are in the position of maximum compression or close to that position. The gases are heated by compressing the air in the cylinders using an electrical machine, or using a heating system in the intake. | 02-11-2010 |
| 20110067665 | METHOD AND CONTROL DEVICE FOR STARTING AN INTERNAL COMBUSTION ENGINE COMPRISING A HEATING DEVICE FOR HEATING A COOLANT - In a method, the starting behaviour of an internal combustion engine ( | 03-24-2011 |
| 20130087114 | METHOD AND DEVICE FOR REDUCING THE TEMPERATURE TOLERANCE OF SHEATHED-ELEMENT GLOW PLUGS - A method for reducing the temperature tolerance of sheathed-element glow plugs is described, in which, in a first step, the sheathed-element glow plugs of an auto-ignition internal combustion engine are classified into at least two temperature classes, at least one temperature class including a temperature range above a setpoint temperature range, at least one temperature class including a temperature range below the setpoint temperature range, and/or one temperature class including the setpoint temperature range. In a second step, the control voltage of sheathed-element glow plugs which were assigned to a temperature class which includes a temperature range above the setpoint temperature range is reduced, and the control voltage of sheathed-element glow plugs which were assigned to a temperature class which includes a temperature range below the setpoint temperature range is increased. A device for performing the method is also described. | 04-11-2013 |
| 20130118432 | GLOW PLUG AND METHOD FOR PRODUCING A GLOW PENCIL - The invention relates to a glow plug for a diesel engine, said glow plug comprising a ceramic glow pencil, which has a heating portion, and a housing, from which the glow pencil protrudes, wherein the glow pencil has a ceramic inner conductor, an insulation layer surrounding the inner conductor, and a ceramic outer conductor layer arranged on the insulation layer. In accordance with this disclosure, the outer conductor layer in the heating portion only partially covers the insulation layer. | 05-16-2013 |
| 20130152894 | STOP/START ENGINE GLOW PLUG HEATER CONTROL - Methods and systems for operating a glow plug are disclosed. In one example, glow plugs of a compression ignition engine are selectively operated during automatic engine starting. The methods and systems may be useful to reduced glow plug degradation and improve emissions of an automatically started engine. | 06-20-2013 |
| 20140090618 | GLOW PLUG AND METHOD FOR MANUFACTURING GLOW PLUG - A glow plug including a metal sheath tube having a closed front end; a heating element accommodated within the sheath tube; insulating powder filling the interior of the sheath tube so as to surround the heating element; a rod-shaped metal lead connected to the heating element and inserted into the sheath tube from the rear end thereof; and a seal member located in a seal portion at the rear end of the sheath tube to hermetically seal the gap between the sheath tube and the lead. The glow plug is characterized in that the sheath tube is formed to have a substantially uniform outer diameter over an axial range including and extending beyond a range where the seal portion is formed, and the sheath tube has an engagement projection formed at the seal portion and deformed so as to protrude radially inwardly. | 04-03-2014 |
