The first period of time is compared to a desired cycle-on period of time during each cycle and the second temperature value then is adjusted for a subsequent cycle of the device so the first period of time when the device transfers heat approaches the desired cycle-on period of time. There may also be provided temperature controls for a liquid heater having a jacket containing the liquid. The jacket has an inner heated wall and an outer wall spaced apart from the inner wall.

  • Patent number: 7017828
    Abstract: For the purposes of increasing pilot visibility and comfort in small planes during winter conditions, this invention provides an auxiliary heating system. Prior to actual flight, that is to say that during start up, warm up, taxi and takeoff, a small aircraft does not intake sufficient outside air to warm the cabin and defrost the windshield. The normal heating system on a small plane depends upon ram air when the plane is flying at normal speeds. This invention consists of a simple replacement part, mainly an electric blower which sucks in air from outside the aircraft and forces it through the muffler shroud and thereafter into the cabin and defroster ducts. The system is operated by a switch located on the control panel. Once the aircraft is in flight, the system may be shut off as there is sufficient ram air to heat the small aircraft.

The heat exchanger is also fitted with an overheat sensor (8) and a flame sensor (9) to monitor or detect overheating of the air heater during operation and the formation of flames during starting by means of a control device (6) and optionally to limit overheating or to disconnect the air heater. The overheat sensor (8) is mounted as a hot air temperature sensor in the area adjacent to the blower in the heat exchanger (4), especially with no wall contact in the hot air flow (5).

  • Patent number: 6540151
    Abstract: An engine-independent vehicle heating system has a connection piece that communicates with a combustion chamber and is linked with a fuel supply. The heater system has a glowing body that is fastened in the connection piece and evaporates and ignites the fuel at least during a starting phase of the heater system. A sieve element that is disposed in the connection piece encloses the glowing body and transports the fuel supplied to the connection piece in the direction of the combustion chamber. The sieve element in the interior of the connection piece is at least partially spaced from an inner wall of the connection piece facing the sieve element.

  • Patent number: 6536679
    Abstract: The invention is based on a heating system for a motor vehicle, which is driven by an internal combustion engine (10), in which a heater (30) includes a combustion chamber (32) with a fuel injection device (34) and an ignition device (35) and also includes an air blower (40), and is triggered as a function of operating parameters and/or ambient parameters of the motor vehicle and/or of the internal combustion engine (10) or by actuating signals. It is proposed that the combustion chamber (32) is connected to the exhaust system (62) of the internal combustion engine (10) in the region of an exhaust manifold (62) of the internal combustion engine (10), between outlet valves (24) and a exhaust gas catalytic converter (56), via an exhaust line (42).

  • Patent number: 6536680
    Abstract: In a combustor for supplying combustion heat to a heater core and an intake side of an engine, when the engine is started, combustion gas is supplied to an intake side of the engine while non-combustion air is introduced into a combustion gas passage partitioned from a water passage of the heater core by a heat-conduction partition member. In this case, non-combustion air is used as an air curtain for interrupting a heat transmission from the combustion gas of the combustion gas passage to water of the water passage.

  • Patent number: 6427924
    Abstract: A combustion type heater of this invention includes fuel distribution means 11 for distributing a fuel to the whole surface of a wick 10, disposed upstream of the wick in a fuel passage. The fuel distribution means comprises fuel distribution grooves 15 and a fuel dispersion plate 16 having a large number of holes bored therein. The fuel distribution means can quickly supply the fuel to the whole surface of the wick. To shorten the heating time of the wick, the heater of the present invention uses a wick heating glow plug 14b outside an ignition glow plug 14a, or a planar heater 18, for heating the wick.

  • Patent number: 6364212
    Abstract: The invention relates to a heating device, especially for a motor vehicle, with a burner, to which fuel is supplied from a tank via a fuel line by means of a pump, especially a piston pump, and with an electronically controllable valve means which is inserted into the fuel line and which can be controlled by a control means. To ensure problem-free feed of fuel to the burner independently of the pump pressure, a pressure reservoir is assigned to the valve means, fuel being delivered by means of the pump controlled in a clocked manner by the control unit, to the pressure reservoir and from the latter to the burner, without the action of the pump.

  • Patent number: 6220522
    Abstract: An internal combustion engine having a combustion heater capable of simply preventing thermal damages to structures of intake system of the internal combustion engine, enhancing a starting characteristic of the engine in a low-temperature state, even when a compression ratio of the internal combustion engine is decreased, and speeding up of warming of an oil. The combustion heater is connected via a combustion gas introducing passageway to an intake pipe, whereby a combustion gas emitted from the combustion heater is introduced into the intake system via the combustion gas introducing passageway. In introducing the combustion gas, an exhaust gas cooler is arranged in the combustion gas introducing passageway for cooling off the combustion gas flowing therethrough. A bypass passageway is connected astride the exhaust gas cooler in bypass to the combustion gas introducing passageway.

  • Patent number: 6213406
    Abstract: It is sought to reduce combustion rise time at the start of driving, increase the combustion efficiency per unit heat exchanger volume and reduce the heater size. A ring-like fuel evaporating medium 4 is provided on an end wall of a combustion chamber formed in a combustion cylinder 1. The end wall has a combustion air lead holes formed, for forming a vortex flow, in its portion surrounded by the fuel evaporating medium. Fuel is supplied to a space in the vicinity of an upper part of the fuel evaporating medium. A combustion gas passage is formed by proving a first combustion gas collecting zone downstream a second combustion chamber adjacent to the first combustion chamber. A second combustion gas collecting zone 10 is provided around the first and second combustion chambers. The first and second combustion gas collecting zones 9 and 10 are communicated with each other by a plurality of connecting pipes. Combustion gas is exhausted from the second gas collecting zone 10.
