Definitions

  • the invention relates to a device for influencing the control times of valves of an internal combustion engine, the device having two devices which are arranged coaxially to one another and are provided with rotary motion transmitting elements, one of which is radially adjustable relative to the other and cooperates with a camshaft actuating the valves.
  • DE-OS 34 21 028 Also known is an internal combustion engine (DE-OS 34 21 028), in which two parallel camshafts, which actuate two intake valves and two exhaust valves per cylinder, are driven by means of a chain. A chain tensioner is provided between the load strand and the lost strand of the chain.
  • the object of the invention is to arrange the device so that on the one hand two parallel camshafts of an internal combustion engine are driven and on the other hand the control times of the valves can be influenced.
  • the device not only serves as a connecting link between the two camshafts, but also influences the valve timing, preferably intake valves.
  • the device requires little space due to the arrangement between the camshafts.
  • a multi-cylinder internal combustion engine 1 shows a cylinder head 2, which is fastened with screws 3, 4 to a housing, not shown, which comprises the cylinder and the crank chamber.
  • a separation plane 5 is provided between the cylinder head 2 and the housing.
  • the cylinder head 2 is designed to accommodate two parallel camshafts 6, 7. Bearings 8, 9 and 10, 11 serve this purpose.
  • the camshaft 7 has cams 12, 13 on both sides of the bearing, which cooperate with two intake valves per cylinder; the intake valves are not shown.
  • the other camshaft 6 comprises cams 14, 15 which are attached on both sides of the bearing 11.
  • the cams 14, 15 cooperate with two exhaust valves per cylinder, which are also not shown.
  • the inlet and outlet valves extend on axes 16, 17 which run in a V-shape.
  • the camshaft 7 is driven by means of an element 18, which transmits rotational movements - toothed or sprocket wheel - which is connected via a continuous link 19 - chain, toothed belt - to a crankshaft, not shown, of internal combustion engine 1.
  • the camshaft 7 drives the camshaft 6 with the interposition of a device 20.
  • the camshaft 7 is designed to be adjustable for the purpose of influencing the timing of the intake valves, with other values, the camshaft 7 can have a different rotational position relative to the camshaft 6 exhibit.
  • the central longitudinal axis A-A of the devices 21, 22 rotating during operation of the internal combustion engine 1 lies on a central longitudinal plane B-B between the camshafts 6, 7.
  • the central longitudinal axis A-A is offset relative to a central transverse plane C-C of the camshafts 6, 7 - distance D -.
  • the central axis A-A is closer to the cylinders of the housing or the parting plane 5 than the central transverse plane C-C of the camshafts 6, 7.
  • journal ends 29, 30 which run coaxially with the devices 21, 22 and are received by bearings 31, 32 of the cylinder head 2.
  • Each bearing 31 or 32 has a bearing block 33 and a bearing cover 34 which is held on the bearing block 33 by screws 35, 36. The latter is firmly connected to the cylinder head 2.
  • the radial adjustment of the device 22 and the camshaft 7 for varying the timing of the intake valves relative to the exhaust valves is carried out hydraulically, depending on the load on the internal combustion engine, the hydraulic oil via oil bores 37, 38 in the bearing 32 or bearing end 30 of the device 20 is fed.
