Heater for a vehicle powered by an internal-combustion engine

Burner of a vehicle heater

A device for thermal regeneration of particle filters is provided for use with a diesel engine exhaust system with a particle filter. The device includes a burner for heating the particle filter during regeneration of the particle filter. A combustion air supply is provided connected to the burner for supplying combustion air. A fuel pump arrangement is provided preferably including plural pumps which are individually actuatable to deliver fuel dependent on the speed and load condition of the diesel engine.

Device for the thermal regeneration of particle filters for diesel

A particle filter for the exhaust gases of internal combustion engines is described, which can be regenerated by burning free, and in which the filter cartridges (12) include a support tube (16) with a lining of filter material (20). The support tubes 16 are conical. The lining with filter material (20) is preferably carried out such that the filter cartridge (12) has a cylindrical shape, i.e., the filter material (20) lining is thicker on the inlet side than on the outlet side. However, lining with an equal thickness of filter material (20) over the entire length of the conical part of the filter cartridge (12) is also shown.

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

With a fluid fuel driven standard heating for motor vehicles, whose combustion chambers are equipped as vaporizer burners, a heater plug with open heater coils up to now would be installed in the usual way. What is disadvantageous for the operation, particularly in the starting, is the voltage dependence of such a heater plug. Also, with time an increasing carbonization would be established. According to the invention the vaporizing of the liquid fuel occurs under a seal by the use of a rod heater plug. The ignition can--independent of voltage--occur with the help of a spark plug (high voltage electrode). In a construction design the vaporizer is developed as a heat pipe, in which the rod heater plug is arranged.

Central heating for motor vehicles and such mobile units

A soot filter for diesel-powered vehicles has two diesel particle filters which are connected to a preliminary muffler via separate ducts, which open radially into a filter prechamber. The exhaust gases can be sent through one of the diesel particle filters or the other by a damper control device, with the dampers being arranged far away from the filters, in the vicinity of the preliminary muffler. Thus, the dampers are located at a fairly great distance from the burner, which is arranged on the front side of the diesel particle filter, and which is designed such that it produces an approximately disk-shaped flame that is directed toward the front side of the diesel particle filter.

A side channel blower, preferably for burners for cleaning soot particle filters mounted in exhaust gas lines of vehicles by burning off, is shown, in which a chamber housing (6) with a chamber (5) is arranged on the air discharge side, wherein air flows into said chamber from the side channel blower (1) and said chamber permits adjustable return of air from said chamber into the annular channel (8) via a bypass (12, 13) and return of additional air, also into said annular channel (2), via an air transfer channel (9) that can be closed with a valve (16), and the air delivered can be fed from said chamber to the filters for cleaning by burning off via two air discharge openings (8a, 8b), which can be closed such that one discharge opening is open and the other discharge opening is closed.

Arrangement for supplying heat to the cooling fluid of a combustion engine, with a heating apparatus, which has a combustion chamber for gaseous or for liquid fuel, and with a heat exchange device, with which heat generated by the heating apparatus can be transferred to the cooling fluid. The heating apparatus is connected on the outside of the engine block of the combustion engine in such a way, that the heat transfer from the hot combustion gases from the combustion chamber to the cooling water or fluid takes place through the outer wall of the engine block.

Cooling water heater for internal combustion engines

A combustion chamber for heating systems operated with liquid fuel can be used as vehicle heaters but also as heating systems for e.g. cooking purposes and whose control range is expanded as compared with known devices. The combustion chamber includes two sections separated from the combustion space by a plate with a passage opening. Depending on the purpose of use, a different flame guiding insert is arranged between the combustion space and the combustion chamber.

Combustion chamber for heating devices

An electromagnetically operated fuel feed pump has an electronic control which comprises a phototransistor circuit with a delay element and a threshold switch. With this control a wear-free operation of the control is possible in a space-saving arrangement.

Control device for metering pump

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.
