The present invention relates to a flame glow plug having a combustion chamber which has an outlet opening for the flame, a fuel supply, in particular a blockable fuel supply, for the provision of a fuel flow to the combustion chamber, an air supply for the provision of an air flow to the combustion chamber and an ignition device, in particular an electrically operated heating element, which is arranged in the combustion chamber or which extends into the combustion chamber and which is made to ignite the air/fuel mixture arising from the provided fuel flow and the provided air flow. The air supply is made controllable in quantity to selectively operate the flame glow plug as a torch or as a secondary fuel injection apparatus. The invention furthermore relates to a regeneration apparatus for a particulate filter of an exhaust gas system, to an exhaust gas system for a combustion engine as well as to a method for the operation of a regeneration apparatus.

The invention relates to a glow plug comprising a housing (1), a glow element (2) which extends out of the housing (1), a supply lead (4) which is connected to the glow element (2) via a contact spring (5) and is enclosed by the housing (1). According to the invention, the contact spring (5) is a sleeve having at least one slit (6) extending transversely to the longitudinal direction of the sleeve.
摘要:
A heating flange especially for the preheating of the intake air of an internal combustion engine with a frame (8), a supporting ceramic element (2) with a heating band (10) fitted thereto. The supporting ceramic element 2 is held in the frame at an inner side of the frame, and a support spring (1) is arranged between the supporting ceramic element (2) and the inner side of the frame. The support spring (1) is a leaf spring which is straight in the non-stressed state, and sits under an initial prestess between the supporting ceramic element (2) and the inner side of the frame. As a result of this configuration, low friction arises between the supporting ceramic element (2) and heating band (10), as well as leaf spring (1), which reduces failures due to vibratory loading, and a defined initial spring tension with a defined spring deflection is produced.
摘要:
A glow plug including plug body composed of an electrically insulating plastic material, a heating rod having an inner pole connected to heating elements, and optionally, control elements, and an outer pole which is electrically insulated from adjoining components of the plug body.
摘要:
Device for creating a temperature gradient, especially in gaseous media, comprising at least one ohmic resistor and at least two non-conducting insulators and at least one casing and at least one elastic element positioned between the non-conducting insulator and the casing.
摘要:
The invention relates to a system for introducing fuel into the exhaust line of a motor vehicle, having a fuel evaporator with a housing, which has an inlet and an outlet, and a heating device arranged in the housing, and a pump for pumping fuel into the fuel evaporator via the inlet. Provision is made for an inlet of the pump to be connected to a branching, which encompasses a first branch for supplying fuel and a second branch for supplying air. The invention further relates to a fuel evaporator for such a system
摘要:
A heating element for preheating intake air for an internal combustion engine and having a housing for attaching the heating element to an air intake line of the internal combustion engine. At least one heating strip (1), which runs in windings (1a), is held in the housing and is provided with electrical terminals (6) that lead from the housing to the outside. The heating strip (1) is held in the housing by a support (3) running between two housing walls, which runs, electrically insulated, through the windings (1a) of the heating strip (1).
摘要:
A glow plug including a glow plug body formed from a single piece tube, the single piece tube including a plug tip area with a glow element disposed therein, a control area with a control element disposed therein, and a connection area with an inside connection lead adapted to be connected to an electrical terminal where the plug tip area has a different diameter than the control area and/or the connection area of the single piece tube.
摘要:
Rod flame glow plug for preheating the intake air of an autoignition internal combustion engine with a housing having a fuel connection with a metering device and an electric connection, and at least one heating rod located in the housing. The heating rod is formed of a glow tube (8) filled with an electrically insulative filling material (10) and at least one regulating coil (2) and a heating coil (1). The coils are embedded in the filling material (10) and are connected in series to one another and with the electric connection (9). The regulating coil (2) is formed of a CoFe alloy.
