Definitions

  • the present invention relates to a method for regenerating a particle filter arranged in thermal proximity to a catalyst unit in an exhaust duct connected to an internal combustion engine, such as is often utilized to power a vehicle.
  • soot particles are also formed in addition to water vapor, nitrogen oxides and carbon dioxide. Small quantities of uncombusted hydrocarbons and carbon monoxide also occur.
  • a diesel engine provided with a particle filter greatly reduces particle emissions.
  • the particle filter has to be regenerated more or less continuously so that it does not become full and cause high pressure drops across the exhaust system.
  • an exhaust gas temperature of at least 250° C. and sulfur-poor fuel ⁇ 30 ppm are necessary.
  • the exhaust gas temperature is usually lower than 250° C., which leads to soot accumulating in the particle filter.
  • detrimental level shall be taken to mean that if the operating state is subsequently changed and regeneration of the filter begins, there is an imminent risk of overheating with permanent damage to the filter as a consequence. Moreover, there is a risk that the magnitude of the exhaust back-pressure can threaten the functioning of the engine.
  • EP 341 832 describes a system comprising a filter in which soot particles are caught. The soot particles are then combusted in a nitrogen dioxide environment. The nitrogen dioxide is formed from within the exhaust gases from nitrogen monoxide in an oxidation catalyst arranged upstream of the filter.
  • One problem with the system described in EP 341 832 is that the capacity for converting the soot particles into carbon dioxide is low in operating conditions with low exhaust gas temperatures. In this connection, the regeneration of the particle filter requires too much time or, as the case may be, is inadequate, then the filter gradually becomes blocked with increased pressure drop as a consequence. This in turn results in the filter having to be serviced frequently.
  • One object of the invention is therefore to provide a method which makes possible effective regeneration of particle filters and is moreover easy to apply to internal combustion engines.
  • an injection unit assigned to the internal combustion engine supplies fuel to an exhaust system connected to the engine at times when the engine is driven with low engine load, an exhaust pressure regulator arranged in the exhaust system then being activated.
  • a catalyst unit arranged in the exhaust duct in thermal proximity to the particle filter is exposed to the fuel supplied, which is oxidized.
  • the particle filter is heated to such a temperature that soot particles are converted into carbon dioxide in reaction with oxygen contained in said exhaust gases.
  • the injection unit can consist of a separate unit which has an injector located in the exhaust duct, or of the existing injection system of the internal combustion engine.
  • the invention makes use of the fact that an exhaust pressure regulator can be used at low load in order to build up a back-pressure in the exhaust system which increases the temperature of the exhaust flow.
  • the fuel is supplied by means of injectors assigned to the combustion chambers of the engine.
  • the fuel is supplied as indicated above, when the engine is driven at low load and the exhaust pressure regulator is activated, and at such a stage that fuel is allowed to pass through the combustion chamber into the exhaust duct in a non-combusted or only partly combusted state. This is achieved by supplying the fuel at a delayed crank angle position in relation to normal injection; that is to say, during the expansion or exhaust stroke.
  • the invention also relates to a vehicle in which the method described above is implemented.
  • FIG. 1 diagrammatically shows a vehicle comprising an internal combustion engine equipped with a particle filter which is regenerated by a method according to the present invention
  • FIG. 2 diagrammatically shows, in greater detail, a turbocharged diesel engine with a particle filter according to the arrangement of FIG. 1 ;
  • FIG. 3 graphically shows the volumetric flow of injected fuel quantity during normal operation and at low engine load when regeneration takes place.
  • FIG. 1 shows a vehicle 1 equipped with an internal combustion engine 2 and a gearbox 3 coupled to the engine.
  • the gearbox has an output driving shaft 4 which, via a propeller shaft 5 , drives at least one pair of driving wheels 6 .
  • the vehicle 1 is constructed around a frame 7 which is supported by the driving wheels 6 , and preferably a set of steerable wheels 8 .
  • the vehicle preferably comprises (includes, but is not necessarily limited to) a cab 9 .
  • the internal combustion engine is equipped with an exhaust system 10 which comprises an exhaust pipe 11 connected to the outlet ports of the engine.
  • a turbine 12 is preferably arranged in the exhaust system 10 and forms part of a turbo unit 13 and is thus mechanically coupled to a compressor 14 arranged on the intake side (not shown) of the engine.
  • turbo compound system There may also be a turbine mechanically coupled back to the driving shaft of the internal combustion engine in a turbo compound system.
  • the engine is of the diesel type, which means that soot particles are formed during the combustion process.
  • the exhaust system is therefore equipped with a particle filter 15 .
  • An oxidation catalyst 16 is arranged in thermal proximity to the particle filter.
  • thermal proximity shall be taken to mean that the reaction which takes place in the oxidation catalyst is capable of heating the particle filter.
  • the oxidation catalyst is usually mounted upstream of and in direct proximity to the particle filter, but it is also conceivable to integrate the particle filter and the oxidation catalyst on a common bearing structure where catalyst material is spread over the filtering body.
  • the soot particles can also react directly with the excess oxygen O 2 present in diesel exhaust gases, but a prerequisite for this is that the temperature exceeds approximately 600° C.
  • This reaction is several powers of ten faster than the reaction in which NO 2 reacts with the soot because the concentration of oxygen O 2 remaining in diesel exhaust gases is approximately three powers of ten greater than the concentrations of NO 2 are. If this temperature is used for regeneration of the soot filter, the whole regeneration can be limited to a few minutes.
  • FIG. 2 shows in greater detail the internal combustion engine 2 which is arranged for regeneration of a particle filter according to the invention.
  • the internal combustion engine preferably forms part of a driving unit for a truck or a bus.
  • the engine is advantageously of the directly injected diesel engine type in which a turbo unit 13 with an exhaust-driven turbine 12 and a compressor 14 arranged on the turbine shaft is used for compression and supply of combustion air.
  • Intake air is supplied to the supercharger from an air filter 17 for compression, after which the compressed air is cooled as it passes through an intercooler 18 before it is supplied to the intake manifold 19 of the engine.
  • the exhaust gases of the engine are collected in a conventional way in an exhaust manifold 11 and are then conducted to the turbine 12 of the supercharger 13 for driving the compressor 14 .
  • the exhaust gases are then conducted onward via an exhaust pressure regulator 20 to a muffler unit 21 with a particle filter 15 .
  • the exhaust pressure regulator 20 can be of a kind known per se and comprises a piston valve with a pneumatically controlled piston 22 and a valve disk 23 mounted at the opposite end of a rod.
  • a regulating air pressure acts against the piston 22 via a compressed-air line (not shown) which is connected to a compressed-air system contained in the vehicle, which is used for generating power for auxiliary units in the vehicle.
  • a control unit 24 is connected to the exhaust pressure regulator 20 via the compressed-air line 25 for controlling the regulating pressure depending on input data.
  • Such input data is provided via, for example, a line 26 to the particle filter 15 .
  • the exhaust pressure regulator can be activated by, for example, detection of the particle quantity in the particle filter 15 having reached a certain level. Alternatively, activation can take place on detection of the pressure drop in the particle filter having reached a certain level. Another variant is to detect whether the engine has worked at low load for a certain time.
  • the valve disk can therefore be set between fully open position and active position, where a given exhaust pressure is defined by the interaction of the valve with the gas flowing through.
  • the exhaust pressure regulator 20 can be activated to different degrees depending on how hot the exhaust gases are.
  • the exhaust gas temperature can be measured and the exhaust pressure regulator can be controlled until its desired temperature is obtained.
  • the control unit of the engine can, with a known ambient temperature in combination with the current operating point, calculate the exhaust gas temperature and then control the exhaust pressure regulator until the desired exhaust gas temperature is obtained.
  • FIG. 3 shows diagrammatically the volumetric flow of injected fuel quantity during normal operation and at low engine load during regeneration.
  • the regulation of injected fuel quantity and the angle position of the crankshaft when injection takes place are controlled by the control unit 24 in a manner well-known to the expert.
  • An example of a control unit for vehicles is given in SAEJ1939/71,1996.
  • the graph shows the volumetric flow as a function of the crankshaft angle position, which is indicated with the bottom and top dead centers of the piston as reference points.
  • the four strokes of the internal combustion engine are indicated along the x axis, the intake stroke between 0° and 180°, the compression stroke between 180° and 360°, the expansion stroke between 360° and 540°, and the exhaust stroke between 540° and 720°.
  • Curve A shows the fuel quantity supplied for an operating case when the engine is working under normal load. Fuel is then supplied at the transition between the compression stroke and the expansion stroke with a duration of between 3 and 30 crank angle degrees.
  • the curves B 1 -B 3 show the fuel quantity supplied under low engine load for regeneration of a particle filter arranged downstream of an oxidation catalyst in the exhaust duct.
  • the fuel is preferably supplied during the expansion stroke or the exhaust stroke within a range covering 30° to 90° after top dead center between the compression stroke and the expansion stroke. A wider range of 0° to 360° after top dead center between the compression stroke and the expansion stroke is possible; that is to say, during the expansion stroke and the exhaust stroke.
  • fuel is supplied between 30° and 180° after top dead center between the compression stroke and the expansion stroke.
  • fuel is supplied 270° after top dead center.
