Definitions

  • the invention relates to an air intake system of a multi-cylinder internal combustion engine according to the preamble of claim 1.
  • An air intake system known from DE-AS 1 066 887 consists of two V-shaped intake lines. Air filters are attached to both intake lines at the front of the motor vehicle and at the ends of the V-legs. In the V-center, the intake lines unite in a mouthpiece, from which a common line leads to the carburetor of the internal combustion engine. The upper halves of the air intake lines are attached to the bonnet cover and, when the bonnet cover is closed, are sealed and placed on the lower, fixed halves.
  • the two intake lines are routed in a U-shape around the internal combustion engine, there is sufficient space above and to the side of the internal combustion engine for the attachment of additional devices.
  • the symmetrical design and the same dimensioning of the intake lines offers the possibility of arranging an air mass meter in only one of the two intake lines and indirectly measuring the total air mass flow by detecting half the air mass flow. Any difference that may occur between the two air mass flows can be compensated in a known manner by the two lambda signals of the stereo lambda control.
  • the air intake system consists of two parallel intake lines 4, 5, two right-angled air filters 6, 7 and a downpipe 8, with the two legs 9, 10 of which the air filters 6, 7 are connected. Downstream from the downpipe 8 are an air mass meter 11, a throttle valve housing 12 and a distributor 13 to the two rows of cylinders 2, 3.
  • the two legs 9, 10 of the downpipe 8 form the middle U-web area.
  • the air filters 14, 15 are attached at the ends to the intake lines 16, 17, which are bent at right angles to the internal combustion engine and are connected to the legs 9, 10 of the downpipe 8.
  • the air mass meter 11 is inserted into an intake line 17 and measures only half the air mass flow. Since the intake lines are the same in length and cross-section, their flow resistance and thus the air mass flow are the same.
  • the signal of the air mass meter 11 is significant for the total air mass flow and the amount of fuel to be injected can be measured according to it. If, for example, different air mass flows result from pipe deposits and thus a mismatch in the injection quantity, this can be determined by the signals from the two lambda probes 18 and corrected on the control unit (not shown).
  • the exhaust system is also constructed symmetrically.
  • the exhaust pipes 19, 20 leading away from the two rows of cylinders 2, 3 open into Bus lines 21, 22 into which the lambda probes 18 are inserted.
