Definitions

  • the present invention relates to a method for warming an after-treatment burner system.
  • a particulate filter is incorporated in an exhaust pipe for flow of an exhaust gas to capture particulates (particulate matters) in the exhaust gas.
  • the exhaust gas from the diesel engine in a normal operation status rarely has a chance to reach a temperature level at which the particulates burns by themselves. Consequently, an oxidation catalyst having active species such as Pt and Pd is integrally carried by the particulate filter.
  • the fuel (HC) added upstream of the particulate filter undergoes the oxidation reaction during its passing through the frontward oxidation catalyst.
  • the exhaust gas heated by heat of the reaction and flowing into the particulate filter just behind increases a catalyst bed temperature of the particulate filter to burn off the particulates, thereby regenerating the particulate filter.
  • the frontward oxidation catalyst hardly has a catalyst bed temperature elevated enough for sufficient catalytic activity and thus an activated oxidation reaction of the added fuel in the oxidation catalyst, failing in effective regeneration of the particulate filter within a short time.
  • Patent Literatures 1 and 2 as prior art document information relating to this kind of technique on exhaust gas purification catalyst or heating of exhaust gas by use of a burner.
  • combustion with a burner which utterly cools off, may be started where forced regeneration of a particulate filter is to be instantly conducted and/or where bed temperatures of different catalysts (such as a selective reduction catalyst for reduction and purification of NO x using urea water or HC as reducing agent) arranged downstream of the particulate filter are to be raised for facilitated catalyst activation.
  • catalysts such as a selective reduction catalyst for reduction and purification of NO x using urea water or HC as reducing agent
  • the sprayed fuel may be unsatisfactorily atomized, disadvantageously resulting in ignition instability.
  • the invention was made in view of the above and has its object to warm a burner at cold start-up so as to improve ignition stability.
  • the invention is directed to a method for warming an after-treatment burner system wherein a burner is arranged upstream of an exhaust purifying member incorporated in an exhaust pipe, said exhaust purifying member being adapted to be heated by combustion with said burner, characterized by comprising energizing an electromagnetic valve-type injector, which serves for fuel spray in said burner, on condition that an ambient temperature surrounding the burner is below a predetermined temperature and with the fuel supply to said injector being stopped, whereby Joule heat by the energization is generated in an electromagnetic coil inside the injector to make the warming.
  • the injector is energized on condition that the ambient temperature surrounding the burner is below the predetermined temperature.
  • the energization brings about Joule heat generated in the electromagnetic coil inside the injector and the fuel inside the injector is heated to have lowered viscosity, so that the fuel spray is satisfactorily atomized to substantially improve the ignition stability.
  • Warming of the burner by energization of the electromagnetic coil is conducted with the fuel supply being stopped, so that the fuel is not sprayed from the injector even if the electromagnetic coil is excited by the energization into switching of a fuel circuit inside the injector.
  • energization time to the injector is varied depending on the ambient temperature surrounding the burner. Then, the lower the ambient temperature surrounding the burner is, the more the energization time to the injector may be lengthened to increase a generation amount of Joule heat.
  • FIG. 1 is a schematic view showing a fundamental structure for an after-treatment burner system to which the invention is applied;
  • FIG. 2 is a flowchart on a control procedure conducted by a controller shown in FIG. 1 ;
  • FIG. 3 is a flowchart showing a detailed control procedure on a burner warming treatment shown in FIG. 2 ;
  • FIG. 4 is a graph showing a relationship between ambient temperature surrounding a burner and energization time.
  • FIG. 5 is a flowchart showing a detailed control procedure on a burner operation treatment shown in FIG. 2 .
  • FIGS. 1-5 show a fundamental structure of an after-treatment burner system to which the invention is applied.
  • reference numeral 1 denotes a diesel engine equipped with a turbocharger 2 .
  • Intake air 4 introduced from an air cleaner 3 is led through an intake pipe 5 to a compressor 2 a of the turbocharger 2 .
  • the intake air 4 pressurized by the compressor 2 a is led to an intercooler 6 where it is cooled.
  • the intake air 4 is further led from the intercooler 6 to an intake manifold 7 and is distributed to respective cylinders 8 of the engine 1 (exemplarily illustrated in FIG. 1 is a case with inline six cylinders).
  • an exhaust gas 9 discharged from the respective cylinders 8 of the diesel engine 1 is led via an exhaust manifold 10 to a turbine 2 b of the turbocharger 2 .
  • the exhaust gas 9 having driven the turbine 2 b is discharged to an exhaust pipe 11 .
  • the burner 14 includes an electromagnetic valve-type injector 15 serving for fuel spray of the burner 14 , an ignition plug 16 for ignition of the fuel injected through an injection port of the burner and a temperature sensor 17 for sensing flame temperature.
  • the temperature sensor 17 is adapted to detect an ambient temperature surrounding the burner 14 even the burner 14 is not ignited, a detection signal 17 a from the sensor being input to a controller 18 which constitutes an engine control computer or electronic control unit (ECU).
  • an operation signal 15 a for operation command to the injector 15 is output. More specifically, energization is conducted to the injector 15 .
  • an operation signal 19 a for operation command to the fuel pump 19 a supplying fuel to the injector 15 is not output to the fuel pump 19 . More specifically, energization to the fuel pump 19 is shut off.
  • the operation signal 19 a for operation command to the fuel pump 19 is output and an ignition signal 16 a for sparking command to the ignition plug 16 is output.
  • a valve-opening signal 21 a for valve-opening operation command to a combustion air valve 21 of a combustion air supply pipe 20 which extracts part of the intake air 4 from downstream of the compressor 2 a of the turbocharger 2 to guide the same as combustion air into the burner 14 is output, and then the operation signal 15 a for operation command to the injector 15 is output.
  • FIG. 2 is a flowchart for explanation of a control. procedure conducted by the controller.
  • the controller When an operation of the burner 14 is requested, it is determined whether the ambient temperature surrounding the burner 14 sensed by the temperature sensor 17 is below 0° C. or not. In the case of below 0° C., the burner warming treatment is selected and after the treatment the determination of the ambient temperature is conducted again. If the ambient temperature surrounding the burner 14 is at or above 0° C., the normal burner operation treatment is selected.
  • the explanation has been made under the assumption that the threshold value for determination of transition to the burner warming treatment is 0° C.; however, of course, the threshold value may be set to any temperature other than 0° C.
  • FIG. 3 shows a detailed control procedure of the burner warming treatment in the flowchart of FIG. 2 .
  • an energization time depending on the ambient temperature is read out from a control map as shown in FIG. 4 .
  • the energization of the injector 15 is ended.
  • the burner warming treatment is ended.
  • FIG. 5 shows a detailed control procedure on normal burner operation treatment shown in the flowchart of FIG. 2 .
  • control of such normal operation of the burner 14 actuation of the fuel pump 19 , start of sparking of the ignition plug 16 , the valve-opening operation of the combustion air valve 21 of the combustion air supply pipe 20 are respectively conducted and then the control of the injector 15 is started.
  • Ignition control of the burner 14 and regeneration control for forced regeneration of the particulate filter 12 or temperature-rising control for increased bed temperatures of different catalysts (such as selective reduction catalyst for reducing and purifying NO x using urea water or HC as reducing agent) arranged downstream of the particulate filter for facilitated activation are conducted.
  • catalysts such as selective reduction catalyst for reducing and purifying NO x using urea water or HC as reducing agent
  • the burner 14 is controlled in such control procedure to energize the injector 15 on condition that the ambient temperature surrounding the burner 14 sensed by the temperature sensor 17 is below the predetermined temperature.
  • the energization brings about Joule heat generated in the electromagnetic coil inside the injector 15 to heat the fuel inside the injector 15 to lower the viscosity thereof, so that fuel spray is satisfactorily atomized to substantially improve ignition stability.
  • Warming of the burner 14 by energizing the electromagnetic coil is conducted with the fuel supply being stopped and with no operation signal 19 a for operation command to the fuel pump 19 being output. As a result, the fuel is not sprayed from the injector 15 even if the electromagnetic coil is excited by the energization into switching of a fuel circuit inside the injector 15 .
  • the energization is conducted to the injector 15 on condition that the ambient temperature surrounding the burner 14 is below a predetermined temperature, and the energization brings about Joule heat generated in the electromagnetic coil inside the injector 15 , which heats the fuel inside the injector 15 to lower the viscosity thereof, so that even if the burner 14 cools off at cold start-up for example in a cold district, the fuel spray can be satisfactorily atomized to substantially improve ignition stability.
  • the burner 14 can be warmed more reliably to improve ignition stability.
  • excess energization can be averted as much as possible to make requisite minimum an electric power consumption required for the energization.
  • a method for warming an after-treatment burner system is not limited to the above embodiment.
  • the exhaust purifying member just behind the burner is a particulate filter; however, of course, the invention may be similarly applied to a case where different exhaust purification catalysts such as a selective reduction catalyst with a property capable of selectively reacting NO x with a reducing agent even in the presence of oxygen or NO x storage reduction catalyst with a property of oxidizing NO x in the exhaust gas and temporarily storing the same in the form of nitrate salt when air-fuel ratio of exhaust is lean and decomposing and discharging NO x through the intervention of, for example, unburned HC or CO when O 2 concentration in the exhaust is lowered are arranged as exhaust purifying members in place of the particulate filter or arranged in addition downstream of the particulate filter. That is, the invention may be similarly applied to an after-treatment burner system where a burner is utilized for temperature rising of these exhaust
