Abstract
The passenger compartment heater 12 has a burner 14 which receives fuel via a metering device 18 and is supplied with air by a positive-displacement blower 20. The i.c. engine has an air intake 28, eg an intake manifold, and an exhaust gas treatment area 30, eg a catalytic converter. The combustion products of the space heater 12 are introduced into the engine air intake 28; this can be done even when the engine is not running by closing a valve 44 to prevent combustion products passing through the engine air filter, and acting on the engine to ensure that the intake and exhaust valves 34, 36 are held partially open to maintain communication between the air intake 28 and the exhaust treatment area 30. Thus not only is the passenger compartment heated but also parts of the engine are pre-heated. When the engine is running, valve 44 is open and the combustion products of the space heater 12 are drawn into the engine by the partial vacuum of the air intake. When the space heater 12 is not required, the positive-displacement nature of the stationary blower 20 prevents air from reaching the engine without passing through the air filter.

VEHICLE HEATING SYSTEMS
Field of the Invention
This invention relates to a heating system for a vehicle.
German Patent Specification No. 195 20 122 A1 discloses
a heating system for a vehicle in which the combustion exhaust To gases which are produced in a burner when a mixture of air and hydrocarbons is combusted are fed into the intake manifold system of an internal combustion engine, i.e. the combustion-air feed area for this internal combustion engine.
us While the internal combustion engine is operating, there is a partial vacuum in this combustion-air feed area, as a result of which partial vacuum the combustion exhaust gases of the heating device are automatically sucked in, and will thus pass into the internal combustion engine, through it and into its 20 exhaust-gas post-treatment system.
In this known system, it is therefore not necessary to provide a blower or the like for the heating device in order to feed in the combustion air.
A drawback of this known system is that it can be placed in a heating operating state only if the internal combustion engine is operating, in order to produce the necessary partial
- 2 - vacuum and ensure that the combustion exhaust gases which leave the heating device can flow through the internal combustion engine to the exhaust area, i.e. can also flow to the exhaust-gas post-treatment system of said internal combustion engine. An object of the present invention is the provision of a heating system of this type that can also be operated in the stationary-vehicle heating mode.
Summary of the Invention
According to the present invention there is provided a heating system for a vehicle comprising a heating device which 15 iS connected at the exhaust end to a combustion-air feed area of an internal combustion engine, an actuator arrangement by means of which the internal combustion engine can be placed in a basic state in which its combustion-air feed area is connected to a combustion-exhaust-gas exhaust area of said internal so combustion engine, and an actuation device by means of which the actuator arrangement can be activated so as to place the internal combustion engine in the basic state in order to implement a stationary- vehicle heating mode.
With the present invention, therefore, in order to implement a stationaryvehicle heating mode, it is ensured in a definite fashion that the internal combustion engine goes into a state in which it is possible for there to be a flow through it. It is therefore ensured that the flow path for, for example,
- combustion exhaust gases which leave the heating device is not blocked and these exhaust gases can therefore pass into the exhaust-gas posttreatment system or exhaust system of the internal combustion engine.
This simplifies the overall design of such a system and ensures, where appropriate, that the combustion exhaust gases of the heating device can be post-treated even in the stationary-vehicle heating mode.
In order to be able to place the internal combustion engine in the basic state, the actuator arrangement may comprise a starter system, preferably a starter-generator system. The starter system preferably acts on the crankshaft of an internal combustion engine which, at least in certain designs, is connected to a valve drive via a V belt or a toothed belt so that the setting position of the valves can also be influenced by appropriately setting the rotary position of the crankshaft and it is possible to ensure that, at least in one cylinder, an inlet valve no and an outlet valve are open at the same time.
Of course, in systems in which the inlet and outlet valves are operated by means of actuators which are assigned to them, the actuator arrangement can also comprise actuators s specifically assigned to the valves.
In order to ensure that the materials leaving the heating device can pass in the direction of the exhaust area of the internal combustion engine, in particular, in the
À 4 stationary-vehicle heating state in which there will generally be no partial vacuum in the combustion-air feed area of the internal combustion engine, the combustion-air feed area of the internal combustion engine may be closed off in the heating device upstream of the junction of an exhaust line of said heating device. It is thus possible to ensure that, for example, the combustion exhaust gases of the heating device do not pass to To the outside via the air filter of the internal combustion engine.
In order to ensure even in the stationary-vehicle heating mode that there is sufficient combustion air available for the heating device, the heating device may be assigned a combustion-air feed arrangement for feeding combustion air into it. It is particularly advantageous if the combustion-air feed arrangement comprises a pump arrangement, it being preferably possible to provide here that, in an inactive state of the pump arrangement, said pump arrangement prevents air flowing so through it.
Such a pump arrangement, which may be, for example, a reciprocating piston pump or rotary vane pump, has various advantageous effects. On the one hand, it is possible to ensure that, in the non-activated state of said pump arrangement, that is to say even when the heating device is out of operation, no additional combustion air can pass into the area of the internal combustion engine that has not been directed via an air filter.
Furthermore, it is ensured that when the internal combustion
engine is activated, i.e. when there is a partial vacuum on the exhaust side of the heating device, a definite quantity of combustion air passes into the area of the combustion chamber of the heating device, which quantity is related, for example, to the number of revolutions or strokes of such a pump per unit time. Brief Description of the Drawing
To The single figure of the drawing is a schematic view of a heating system in accordance with the present invention.
Description of the Preferred Embodiment
The heating system 10 comprises a heating device which is designated generally by 12 and comprises in turn a burner 14 and a heat exchanger 16 as essential system areas. The burner 14 may be a vaporizer burner or an atomizer burner and receives the liquid fuel necessary for combustion via a fuel no metering device 18, for example, a metering valve or a metering pump or the like. The combustion air which is also necessary for combustion is fed to the burner 14 via a blower 20, which is, for reasons which will be explained in more detail below, in the form of an expulsion feed arrangement, that is to say, for example, as a rotary vane pump, as a reciprocating piston pump or the like.
The fuel metering device 18, the blower 20 and a firing element 22, which has the effect of starting the combustion process, are actuated by an actuation device 24 which, as
- - 6 - indicated by an arrow Pa, receives various parameters for setting the operation of the heating device 12. These parameters may be, for example, the ambient air pressure, the ambient temperature and the cooling water temperature of an internal combustion engine 26, which is indicated schematically.
The combustion air which is necessary for combustion with the fuel, which is also input into the internal combustion engine 26, is fed to the internal combustion engine 26 via a To combustion-air feed area 28. The exhaust gases which are generated during the combustion are discharged into an exhaust-gas post-treatment system 30 after the expulsion phase from the individual cylinders. The combustion-air feed area 28 may comprise, for example, what is referred to as an intake manifold in an assignment to each individual cylinder 32. The exhaust-gas post-treatment area 30 can comprise, in a manner known per se, a catalytic converter which has the effect of reducing the proportion of pollutants.
go In the drawing, an inlet valve 34 and an outlet valve 36 are also illustrated schematically in combination with the internal combustion engine 26 or each of its cylinders 32, said valves being opened and closed according to the cycle. It goes without saying that it is also possible to provide a plurality of such s valves, each assigned to a specific cylinder. In addition, there may be an actuator arrangement, which may comprise a starter, preferably a starter-generator, and by means of which it is possible to act, for example, on the crankshaft of the internal combustion engine 26 in order to turn it and thus start the
internal combustion engine 26.
Systems which have the purpose of registering the rotational angle position of the crankshaft, and thus the state of the various components of the internal combustion engine 26, are not illustrated, but they are generally customary in such internal combustion engines. In particular, in order to control the ignition time, and in order to control the injection quantity and the injection time, this information about the rotational angle position JO is input into an actuation device 40 for the internal combustion engine in order to control the operation of the internal combustion engine 26, of course also taking into account other parameters. The combustion exhaust gases or other reaction products which leave the heating device 12 or the burner 14 of the same are introduced into the combustion-air feed area 28, for example, an intake manifold, via an exhaust line 42. A closure valve 44, which can be positioned by means of a corresponding JO actuator arrangement in such a way that it can close off the combustion-air feed area 28 or the assigned intake manifold, is provided upstream of this introduction point, in the respective
intake manifold or the combustion-air feed area 28.
sThe operation of the heating system 10 according to the invention will be described below.
It is initially assumed that the heating device 12 is to be operated in the stationary-vehicle heating mode. This operation
- 8 - therefore takes place when the internal combustion engine 26 is not activated and, for example, a vehicle is to be preheated before being put into operation. For this purpose, the actuation device 24 actuates the blower 20, the fuel metering device 18 5 and the ignition element 22 in order to activate the burner 14. In addition, it is ensured that the combustion-air feed area 28 into which the exhaust line 42 leads is closed off by the valve 44 so that it is possible to prevent the reaction products produced in the burner 14 from passing to the outside via the air filter of the To internal combustion engine 26. In addition, the actuation device 40 of the internal combustion engine 26 activates the actuator arrangement 38 in order to ensure, by acting on the internal combustion engine 26, that both the inlet valve 34 and the outlet valve 36 are in a partially open state. There is thus a connection 15 between the combustion-air feed area 28 into which the exhaust line 42 leads and the exhaust-gas post-treatment area 30 via the internal combustion engine 26 or the cylinder 32 or cylinders 32.
The warm combustion products which are produced in the so heating device 12 thus pass via the exhaust line 42 and the combustion-air feed area 28 through at least one cylinder 32 of the internal combustion engine 26 to the exhaust-gas post treatment system 30. This results in various advantages. On the one hand, in addition to the function of heating the passenger 25 compartment of a vehicle, which is desired per se, various system areas of the internal combustion engine 26, for example, the cylinder head, and in particular also the exhaust-gas post treatment system 30 assigned to it are also preheated so that, when the internal combustion engine 26 resumes operation, it
. - 9 - will already discharge significantly fewer pollutants to the atmosphere. Furthermore, the heating device 12 does not require its own exhaust-gas post-treatment system or the like.
This is advantageous in particular if thermally comparatively wellinsulated and low-mass starting catalysts that may be present are preheated by the combustion products of the heating device 12 so that the combustion exhaust gases of the burner 14 are also converted, and thus fewer pollutants are released. When the internal combustion engine 26 is actuated, the heating device 12 can continue to act as a heat source, during which process the fact that there is a partial vacuum in the combustion-air feed area 28 continues to reliably ensure that, even when the valve 44 is open, the combustion exhaust gases of the heating device 12 pass into the exhaust-gas post-
treatment system 30 of the internal combustion engine 26. The configuration of the blower 20 as an expelling element, which has already been referred to above, has the advantage that at go every working stroke, for example, at each revolution of a rotary vane or the like, a defined volume of combustion air is fed into the burner 14, independently of the partial vacuum which is then present on the exhaust side.
: In a state in which the heating device 12 is not to be activated at all, an essentially air-tight closure is obtained as a result of the provision of the blower 20, which is then also not activated, so that the quantity of combustion air which is fed to the internal combustion engine 26 is not adversely affected by
- 10 any by-pass flows. While the heating device 12 is operating, the partial vacuum present in the combustion-air feed area 28 has an influence only to the extent that the air density, associated with the change in the pressure, will change. The temperature also plays a role here. In particular, if information about the pressure in the combustion- air feed area 28, about the ambient pressure, the ambient temperature and other further operating parameters is present in the actuation device 40 of the internal combustion engine 26, it is possible to affect the actuation of the to blower 20 by means of the communication present between the actuation devices 40 and 24 in order to be able to compensate for such fluctuations in density by correspondingly influencing the quantity of air supplied. On the other hand, it is possible, while taking into account the actuation measures which have already been taken in the region of the heating device 12, to use the actuation device 40 to actuate the various system areas of the internal combustion engine 26 which are influenced by actuation equipment, in such a way that the internal combustion engine 26 can also be operated in an optimised fashion taking no into account the gases or exhaust gases which are fed into the combustion-air feed area 28 via the exhaust line 42. It is thus possible to influence the injection quantity, the start of injection, the ignition time, the position of the valve and the like.
:s The present invention provides a heating system 10 in which a stationary-vehicle heating mode is possible for the heating device 12 thereof even though the combustion products of said heating device are introduced into the combustion-air feed area of an internal combustion engine 26. An important
t - - 11 feature here is that, by utilizing the basically known operating state or the positioning of various components of the internal combustion engine 26 at a given time, it is possible to ensure that the internal combustion engine 26 is placed in a state in which it is possible for the combustion exhaust gases of the heating device 12 to flow through it. This can take place not only, as described above, by acting on the crankshaft and thus also on the camshaft or valves of the internal combustion engine 26 by means of a corresponding drive, but also may be carried 10 out directly, given an appropriate configuration, by the activation of respective valve actuators.
