Power regulating system for the burner of a heater

Vehicle heater

Additional heating arrangement

Heater for a vehicle powered by an internal-combustion engine

Burner of a vehicle heater

An exhaust gas cleaning device for diesel engines has an exhaust gas soot filter (2) with a filter body (6) that is supported in a housing (4) and is regenerated by combustion of the soot when its temperature rises above the middle operating exhaust gas temperature range. A burner (26) is provided, having a combustion air fan (28) whose hot gas side is in flow communication with the exhaust gas soot filter (2), and the filter body (6) is supported in its housing in such a manner that at least a large part of its outer surface is heated externally during operation of the burner (26).

Exhaust gas cleaning device for diesel engines

A method for providing uniform thermal output from a glow plug for use in an auxiliary heater of a motor vehicle having either a 12 volt or 24 volt power supply without the use of multiplier resistors utilizes a glow plug having two heating rods having the same electrical resistance and three electrical terminals. One end of the first and second rods are permanently electrically connected respectively to the first and third terminals and the other end of the first and second rods are permanently electrically connected to the second terminal. The vehicle voltage is determined and if the 12 volt supply is present the first and second terminals are connected to the power supply and the first and third terminals are electrically connected to each other to place the heating rods in parallel. If a 24 volt supply is present, the first and third terminals are connected to the power supply with the second terminal left in connected thereby placing the heating rods in series.

Method for connecting a glow plug for operation at two different voltages

A heating device for pre-heating liquid fuel, especially diesel fuel and for heating devices of a low heating performance which are independent from a motor have a heating performance which is suitable for mounting into vehicles, which are driven by the liquid fuel. The pre-heating is effected by a transmission of heat of the exhaust gas to the fuel of the heating device, the fuel being lead through a continuous tubular wrapping in one layer or through a hollow cylinder formed or positioned around the exhaust pipe. This wrapping or hollow cylinder is part of the fuel main from the fuel tank to the fuel supply pump of the heating device. A pre-heating of the content of the tank is effected by the return of the pre-heated, but not burnt fuel through a fuel return main back into the tank. A heat transmitting jacket is advantageously disposed between the wrapping, or a hollow cylinder and the exhaust gas pipe.

Fuel pre-heater for liquid fueled engine

In space heaters with pressure atomization burners, which have a small combustion chamber volume, good mixing of air with fuel is achieved practically only in the case of relatively high air flow velocities, which leads, however, to difficulties in terms of ignition, especially at high operating voltages and low temperatures. The blower motor is therefore started first when putting the heater into operation, after which it is disconnected from the power source, so that the speed will again decrease, after which the high-voltage ignition and the fuel supply are turned on, so that the ignition can take place at reduced blower speed, and the high-voltage ignition is turned off and the blower motor is restarted after the flame has been recognized in the burner.

Heater for mobile units

A heating device for pre-heating liquid fuel, especially diesel fuel and for heating devices of a low heating performance which are independent from a motor having a heating performance which is suitable for mounting into vehicles, which are driven by the liquid fuel. The pre-heating is effected by a transmission of heat of the exhaust gas to the fuel of the heating device, the fuel being lead through a continuous tubular wrapping in one layer or through a hollow cylinder formed or positioned around the exhaust pipe. This wrapping or hollow cylinder is part of the fuel main from the fuel tank to the fuel supply pump of the heating device. A pre-heating of the content of the tank is effected by the return of the pre-heated, but not burnt fuel through a fuel return main back into the tank. A heat transmitting jacket is advantageously disposed between the wrapping, or a hollow cylinder and the exhaust gas pipe.

By temperature gradient detection it is determined for the liquid combustion chamber auxiliary heater for motor vehicles, whether e.g. a flame blow-off has taken place, which has to be interpreted as a malfunction and hwich necessitates the discontinuation of fuel supply. Alternatively, it might merely show the switching from a high setting to a low setting. In the latter case a temperature drop to a lower operation temperature occurs also. However, the temperature drop is not as steep as in the case of a flame blow-off. At certain points in time t.sub.1 the target temperature for a point in time t.sub.2 is calculated by the detected temperature according to a certain algorithm having specific device properties as parameters. At this point in time the calculated target temperature is checked for errors.

Heater for motor vehicles which can be operated on several power settings

Formerly unpleasant blue smoke was generated in a vaporizer burner for auxiliary heaters for motor vehicles once the fuel supply was cut off and the flame died down, as the remaining fuel was merely heated up, but not burnt. According to the invention the glow plug is activated for a determined period of time during the after-running phase of the combustion air blower. By this means practically all remaining fuel is vaporized and burnt and therefore the forming of blue smoke and remaining residues in the area of the plug muff and/or the burner is avoided.

Control and method for operating a vaporizer burner

A heater plug is cooled with combustion air for diesel oil-burning heating appliances, especially those provided with a vaporizing burner. The plug is screwed into a burner pipe joint, enclosing but spaced inwardly of the plug. The pipe joint also has inlet for supplying the fuel, and it is fastened to the furnace wall of the heating appliances. The burner carries a continuous lengthwise bore, accessible from one end face and opening into the heater plug coil, the inner end of the bore being connected to the combustion air channel across a proportioning throttle.

An engine-independent heater, particularly a space heater for automobiles comprises a housing which includes a combustion chamber and an antechamber which is tangentially connected into the combustion chamber. The antechamber receives a fuel and air mixture which is ignited in the antechamber and directed into the main combustion chamber. The construction includes the housing carrying an ultrasonic vibrator which is actuated in order to intermix air which is drawn into the housing for the vibrator with fuel which is directed against the vibrator so that the coolant air intermix has there delivered into the antechamber of the heater. The construction includes a nipple connection into the antechamber which sprays fuel from a proportioning pump into the vicinity of the ultrasonic vibrator.

Mixture preparation for engine-independent heaters

A method of manufacturing parts which are otherwise identical but which display different indicia such as a typewriter or the like keys which comprises the steps of injection molding a plurality of identical parts of a plastic having a filler material capable of undergoing a color change, and thereafter exposing individually the identical parts to a radiation source for changing the color of localized portions of the part to display the indicia while retaining the molded color of remaining portions.
