Definitions

  • the invention relates to a method for injecting fuel into the cylinders of a multi-cylinder internal combustion engine according to the preamble of claim 1.
  • crankshaft In a four-stroke internal combustion engine, the crankshaft sweeps through an angle of 720 ° per work cycle, i.e. performs two full rotations before a specific cylinder returns to the same working position, e.g. the next ignition point. In order to be able to record a current position of a cylinder, it is therefore not sufficient to determine the angular position of the crankshaft within one full rotation. In addition, it must be detected whether the machine is currently in the first or in the second half of the work cycle, corresponding to the first or second crankshaft rotation.
  • a position transmitter additionally delivers a position signal with a reference pulse per revolution of the crankshaft, by means of which a known angular position, the synchronization position, is determined. Only when the reference pulse is recognized, in conjunction with the position signal, is the position of the cylinders of the internal combustion engine known exactly, and a synchronization of electrical control functions - ignition, injection, etc. - and the cylinder positions is possible (synchronization time).
  • the object of the invention is to improve the method according to the preamble so that no start time extension occurs and the disadvantages of the known bank injection are avoided.
  • the solution according to the invention is characterized in claim 1. Then the first partial signal of the position sensor at the start determines a current (first) cylinder group consisting of the cylinders whose inlet valves are mostly closed during this first partial signal. A second cylinder group consists of the cylinders, the inlet valves of which are mostly closed during the following partial signal.
  • the preliminary quantity is injected into all cylinders of the second cylinder group at the same time, provided that this signal change is before the synchronization time.
  • the time for this injection can be immediately after the signal change, which has the advantage that no additional arithmetic operation is necessary after the signal change has been detected. As with the first cylinder group, this largely avoids injecting fuel into an open intake valve of a cylinder.
  • the injection into an open intake valve can be completely avoided: since the angular position at which the position signal changes is known, an angle can be specified for each internal combustion engine by which the crankshaft must continue to rotate until none of the Intake valves of the second cylinder group is more open. That the crankshaft has rotated further by this angle can be determined from the position signal from the position transmitter and then trigger the injection.
  • this method involves a little extra computing power, it also means a further reduction in exhaust gas emissions.
  • the pre-quantity is already injected sequentially into the cylinders of the second cylinder group in accordance with the known normal sequence.
  • This advance quantity is increased compared to the normal quantity, which is determined by the computer after the start phase. It is injected only once per cylinder at the start and has, among other things, the task of building up the wall film in the intake manifold. Therefore, this preliminary quantity is also injected into the second cylinder group if the synchronization has already taken place, but then in a sequential order.
  • the known sequential injection begins with the normal quantity. This always begins with the cylinder which, according to normal sequence, follows the last cylinder of this second cylinder group in the case of - actual or imaginary - sequential injection into the cylinders of the second cylinder group Row is.
  • the counting of the cylinders of the second cylinder group in the normal sequence begins with the cylinder whose injection time in the normal sequence has the smallest time interval from the start of the injection into the second cylinder group.
  • an internal control unit M is assigned to an internal combustion engine BKM, which controls the ignition and the fuel injection.
  • a NG camshaft sensor in conjunction with a NA camshaft sensor is used as the position sensor LG.
  • the position encoder generates a static position signal, consisting of two partial signals with an A signal (binary "1") for a first full rotation of the crankshaft and a B signal (binary "0") for the next full rotation of the crankshaft.
  • the position of these partial signals with respect to the positions of the cylinders can be freely selected.
  • the center of each partial signal is 84 ° before the top dead center of the cylinder with number 1.
  • a crankshaft encoder KG with a reference mark RM in conjunction with an assigned crankshaft scanner KA serves as the position encoder PG.
  • This delivers a reference pulse R per revolution of the crankshaft, which determines a synchronization position.
  • the falling edge of this reference pulse R is 84 ° before each top dead center of the cylinder 1.
  • the signal change of the position sensor lies in the middle between two such reference pulses R. This distance is an empirical value for which a particularly favorable signal processing results in a very specific internal combustion engine .
  • Cylinder 1 begins its intake stroke at 0 °, starting from top dead center. Accordingly, the intake valve remains open for the next 180 degrees of crankshaft rotation. This angular range is indicated in the figures with a rectangular bar. After 360 °, cylinder 1 again reaches its top dead center, in the vicinity of which the ignition takes place and the work cycle begins. The ignition area is indicated by a black rectangle. After 720 ° crankshaft rotation, a work cycle is finally completed and the intake stroke begins again.
  • the control unit recognizes the start when the speed of the internal combustion engine has reached a speed threshold N, e.g. is 15 revolutions per minute; this is the case in FIG. 2 at time t1, which is here shortly after the reference pulse R of the position signal.
  • N e.g. 15 revolutions per minute
  • the position transmitter delivers an A signal and, accordingly, the associated current cylinder group (whose inlet valves are mostly closed) consists of cylinders 1, 5 and 6.
  • the preliminary quantity is injected into this immediately after t1, which is indicated in the figure by dotted squares is.
  • the preliminary quantity is injected into the second cylinder group assigned to the B signal with cylinders 2, 3 and 4.
  • the inlet valve of cylinder 4 is still open for a short time.
  • a variant of this is shown in dashed lines in FIG. 2:
  • the injection into the second cylinder group is shifted here by an angle of approximately 90 ° kW to the point in time t2. This then avoids any injection into an open intake valve.
  • the time t2 is determined from the position signal.
  • the normal quantity is injected sequentially in a known normal sequence, which is indicated in the figures with TI squares.
  • the cylinders of the second group are counted in the normal sequence from the start of injection into the second group. For illustration purposes, in cases A and B of FIG. 2 the normal sequence of the cylinders of the second group is shown as a circle with a broken line. From the illustration it follows that cylinder 4 is the last cylinder of the second group and thus the sequential injection with normal quantity begins with cylinder 5.
  • time t1 of the starter identification and the following reference pulse R lie within the same position signal - A signal. Therefore, the preliminary quantity is injected simultaneously into the assigned cylinder group with cylinders 1, 5 and 6 (t1). In this case, however, the synchronization time t2 follows before the signal change of the position signal. Accordingly, cylinders 4, 2, 3 of the next cylinder group receive the advance quantity sequentially, starting with the cylinder of this group, which comes in the normal sequence first after t2 - here cylinder 4. After the injection of the preliminary quantity into the last cylinder - 3 - this cylinder group continues the sequential injection with normal quantity - starting with cylinder 4.
  • a fourth operating case - D in FIG. 3 - the instant t3 of the start detection is in the range of the B signal, so that cylinders 2, 3 and 4 of the assigned cylinder group receive the preliminary quantity at the same time.
  • the reference pulse R follows again before the next signal change of the position signal, so that cylinders 1, 5 and 6 of the next cylinder group receive the preliminary quantity sequentially. With cylinder 1 the sequential injection starts with normal quantity.
