Definitions
- the invention relates to a device and a Methods for recognizing and influencing the Phase position in an internal combustion engine according to Genus of the main claim.
- crankshaft In an internal combustion engine, especially in one with multiple cylinders, with a crankshaft and one The camshaft is dependent on the engine control unit from the recognized position of the crankshaft or camshaft calculates when in which cylinder fuel to be injected and at what time the Ignition must be triggered. It is common that
- the control unit can assign the angle detect.
- crankshaft is within one working cycle turns twice on a four-stroke engine, but can just by scanning the crankshaft the phase position of the internal combustion engine is not clearly determined. at Ignition and injection are in the wrong phase output by 360 ° KW reversed from the control unit. Due to the fact that one cycle of a four stroke Is 720 ° KW and only by means of the sensor in The encoder wheel cannot determine which of the four Pending.
- phase signal fails if the phase signal is incorrect seen every second attempt because of ignition and 360 ° KW crankshaft injection from the control unit incorrectly output. The engine therefore does not jump on.
- one Direct gasoline injection gas from the combustion chamber into the Injectors and the fuel rail pushed back what then leads to the fact that even with the correct phase position Starting behavior is affected.
- the State of the art usually a second transducer or sensor provided, one with the camshaft in Connected encoder disc on your Surface has a reference mark, scanned. That I the camshaft only once during a work cycle turns, the control unit from the Camshaft sensor delivered signal with a single impulse per work cycle the phase angle of the Detect internal combustion engine and a synchronization carry out.
- a second transducer or sensor provided, one with the camshaft in Connected encoder disc on your Surface has a reference mark, scanned. That I the camshaft only once during a work cycle turns, the control unit from the Camshaft sensor delivered signal with a single impulse per work cycle the phase angle of the Detect internal combustion engine and a synchronization carry out.
- Such a system is e.g. in the German patent application P 4230616.7.
- the object of the present invention is to achieve this based on specifying a facility and a procedure by detecting the phase position at the start is possible and through which an improved Start behavior when the phase signal fails. This object is achieved by the characteristic part of the main claim and the Subclaims resolved.
- the device according to the invention and the method according to the invention have the essentials Advantage that existing assemblies and Components are used, no additional Camshaft sensor is required and no extra Pressure sensors are required.
- the Rail pressure evaluation usually takes place directly in the Control unit, without additional circuit. If necessary the pressure signal of the fuel rail sensor also via a simple analog / digital comparator circuit Control unit are fed for evaluation.
- phase If the phase is wrong from the start, it will Injector in question by the Compression back pressure is blown back immediately closed and the pressure increase over, for example the analog / digital comparator circuit to the control unit communicated. Thereupon a resynchronization of Injection and ignition by 360 ° KW from the control unit triggered.
- the fuel rail is part of Direct fuel injection and has the on each cylinder Internal combustion engine 6 branches for the Injectors 5 that directly the fuel Electromagnetically controlled in the combustion chamber inject. With 2 the air is sucked in marked, 3 is the throttle valve and 4 is that Intake pipe, which also branches to each cylinder having. At 8 is the one that acts as a pressure sensor Fuel rail sensor labeled the ruling one Fuel rail pressure is measured. With direct injection 1, the motor only sucks in normal operation Air on and no longer the fuel-air mixture. The Mixture formation in the combustion chamber allows two completely different operating modes.
- FIG. 2 shows a perspective illustration of the fuel Rail 7 for a four-cylinder with four Injector 5 the pressure regulator 11 and the as Pressure sensor acting fuel rail sensor 8. That Reference numeral 10 shows the fuel filter, 9 is the Electric fuel pump.
- the control of the internal combustion engine 6 takes over with direct petrol injection 25 according to Fig. 3.
- reference numeral 16 is the Designated encoder disc, which is rigid with the crankshaft 12 of the internal combustion engine 6 is connected and at her Scope a variety of similar angle marks 13th having. In addition to these similar angle marks 13 there is a reference mark 14, for example by two missing angle marks is realized.
- the encoder disc 16 is the pickup 15, for example an inductive Sensor or a Hall sensor or one Magnetoresistive sensor, scanned.
- the at Passing the angle marks 13 in the sensor 15 generated signals are in the control unit 25 in appropriately processed.
- Phase sensor that the camshaft 26 or one with the Camshaft 26 connected disc with a mark is not needed here.
- the information with respect to the phase position resulting from the output signal of such a sensor is usually obtained here with help the pressure sensor signal of the Fuel Rail Sensors 8 received.
- the control device 25 receives various inputs further for the control or regulation of the Internal combustion engine required input quantities that can be measured by different sensors. 3 these sensors are designated 17. About one Another input is an "ignition on” signal fed that when closing the ignition switch 18 of the terminal 15 of the ignition lock is supplied and the Control unit 25 commissioning the Indicates internal combustion engine.
- the control unit 25 itself comprises at least one central processor unit 20 and memory 19.
- Im Control unit 25 signals for injection and Ignition for unspecified components of the Internal combustion engine determined. This will be signals via the outputs 21 and 22 of the control unit 25 issued.
- the power supply to the control unit 25 takes place in in the usual way with the aid of the battery 23 Switch 24 during operation of the internal combustion engine and one controlled by the control unit itself After-running phase after switching off the engine with the Control unit 25 is connected. In the Follow-up phase will be after the shutdown of the Internal combustion engine 6 information still determined saved, they are then available when switching on again the internal combustion engine 6 to the control unit 25 immediately Available. This information includes in particular also the last angular positions of the crank or Camshaft 12 or 26 and information regarding the last phase.
- the Crankshaft sensor delivered reference mark signal is ambiguous because the crankshaft 12 within of a work cycle spins twice on a four-stroke engine, while the camshaft 26 is rotating only once. It is therefore used to detect the phase angle from Control device 25 under certain operating conditions, especially at the start, which affects the phase position so that if it is faulty, what about the fuel rail Sensor 8 is measurable, the phase position of the ignition and Injection via control unit 25 by 360 ° KW is resynchronized.
- the pressure sensor is in the fuel Rail arranged and with the Fuel Rail Sensor 8 identical.
- the detection takes place Reference mark 14 on the encoder disc 16 a special Injection without ignition at top dead center. at an incorrect phase position will blow back into the corresponding fuel injector 5 with a following pressure increase in the fuel rail 7. After detection the fuel injection valve 5 becomes the pressure increase closed immediately in order to blow back too much prevention. This is followed by re-synchronization of Injection and ignition by 360 ° KW using the Control unit 25.
- phase is correct (injection in Charge change (top dead center) does not take place Pressure increase in the fuel rail sensor.
- the injection and Ignition can be correct with the following cylinder Start phase position.
