A system and method for generating combustion aerosols from liquid fuel. The system includes a furnace with an inner heating tube having a heating tape wrapped thereabout. Further, the system includes a fuel line extending through an inlet end of the heating tube and into the heating tube, and a means for dripping the liquid fuel onto a plurality of different locations on an inner surface of the heating tube. The system further includes a power supply to power the heating tape to heat the inner heating tube to a temperature which can ignite the liquid fuel dripped onto the inner surface of the inner heating tube whereby there is an immediate combustion to form combustion products. Finally, the system includes an air line connected to the heating tube for directing compressed air through the inner heating tube to mix with the combustion products and transport the formed combustion aerosols out of an outlet end of the inner heating tube.

A vehicle heater housing (46) has an inlet area (49), an outlet area (51) and an air flow space (47) for air to be heated with a burner chamber assembly unit (30), to be fed with combustion air and fuel. A heat exchanger area (11), including a heat exchanger housing (12), is elongated in the direction of a housing longitudinal axis (L) with an outer side (24) around which air flowing in the air flow space flows. Heat transfer ribs are on a side of the heat exchanger housing. The heater housing has a housing circumferential wall (56) and an outlet front wall area (58). The heat transfer ribs have a longitudinal edge (64) extending along the housing circumferential wall and a radial edge extending along the outlet front wall area. A distance of the radial edge from the outlet front wall area changes from radially outwards to radially inwards.

A combustion chamber assembly unit for a fuel-operated vehicle heater is provided. The combustion chamber assembly includes a combustion chamber housing (12) with a combustion chamber (18), which is defined by a circumferential wall (14) and by a bottom area (16). An oxidation catalytic converter device (54), through which combustion waste gases can flow, is provided downstream in relation to the combustion chamber (18). The combustion chamber assembly further includes a hydrocarbon storage device (74) or/and a nitrogen storage device (76).

A torch igniter includes an auxiliary fuel injector; an ignition source; and an igniter body carrying the auxiliary fuel injector and the ignition source. The igniter body includes an auxiliary combustion chamber having a side wall extending axially from a first end wall to a second end wall. In some examples, at least a portion of the side wall includes a distributed pattern of cooling apertures, with each of the cooling apertures extending obliquely from an outer surface of the side wall to an inner surface of the side wall. In some examples, the second end wall defines a fluid outlet leading to an outlet tube in fluid communication with the primary combustion chamber, at least a portion of the outlet tube including a distributed pattern of dilution apertures.

A torch igniter includes an auxiliary fuel injector; an ignition source; and an igniter body carrying the auxiliary fuel injector and the ignition source. The igniter body includes an auxiliary combustion chamber having a side wall extending axially from a first end wall to a second end wall, the side wall defining an interior cavity between the first and second end walls. The igniter body further includes a premixing cup residing within the interior cavity including a cylindrical wall radially surrounding the auxiliary fuel injector and an auxiliary air inlet, the cylindrical wall of the premixing cup protruding axially outward relative to the first end wall of the auxiliary combustion chamber through a portion of the interior cavity to delineate a premixing zone radially inward of the cylindrical wall and a recirculation zone radially outward of the cylindrical wall.

A high temperature combustion device is provided that is configured to enable dynamic changes in the combustion environment to provide neutral, oxidizing, or reducing combustion environments. The device may include a blast tube and an air blower configured to motivate air through the blast tube. A nozzle for atomizing a fuel, such as vegetable oil, and more preferably waste vegetable oil, may be disposed in the blast tube. A fuel pump may be configured to motivate the fuel to exit the nozzle. An air supply line may be in fluid communication with the nozzle and may be configured to supply high-pressure air to the nozzle. The high-pressure air may exit the nozzle with the fuel in a first direction, and air motivated through the blast tube by the air blower may pass around the nozzle in a second direction that is substantially parallel to the first direction.
