Definitions

  • the invention relates to a motorcycle with a compact internal combustion engine.
  • Such a motorcycle is known.
  • Its internal combustion engine comprises a VR cylinder arrangement with a gapped cylinder row, the internal combustion engine being installed with a transverse crankshaft.
  • the crank mechanism also acts constrained on the crankshaft so that the two planes formed by the cylinder axes of each row of cylinders intersect below the crankshaft axis.
  • EP 1 146 219 A1 already shows the arrangement of gas ducts in a cylinder head of a VR engine.
  • Inlet and outlet channels are guided largely horizontally, ie transversely to the cylinder axis. All exhaust ports open on one side of the cylinder head, all intake ports on the cylinder head opposite side.
  • the outlet channels of each displaced to the rear row of cylinders are considerably longer than those of the front lying. Also, the inlet channels have these differences in length, but are arranged mirrored. This channel arrangement is less suitable for motorcycle engines, since in particular with the very unequal inlet channels no high power density can be achieved.
  • the object of the subject invention is to provide for a generic motorcycle with internal combustion engine with VR cylinder arrangement a suitable cylinder head, can be achieved with the great engine performance.
  • the object is achieved in the case of a transverse crankshaft (transverse installation), the intake ports of the rear cylinder bank are arranged behind the rear camshaft and the intake ports of the front cylinder bank in front of the rear camshaft or with longitudinal crankshaft (longitudinal installation) the intake ports of the one cylinder bank to the left of an outer camshaft and the intake ports the other row of cylinders are arranged to the right of this camshaft.
  • transverse crankshaft transverse installation
  • the intake ports of the rear cylinder bank are arranged behind the rear camshaft and the intake ports of the front cylinder bank in front of the rear camshaft or with longitudinal crankshaft (longitudinal installation) the intake ports of the one cylinder bank to the left of an outer camshaft and the intake ports the other row of cylinders are arranged to the right of this camshaft.
  • the arrangement of the intake ports on both sides of the intake-side camshaft described in this way ensures that intake passages of the same length and the same shape are used, which are also relatively short, which likewise achieves a high engine output and the greatest possible synchronization and running smoothness of the engine.
  • the engine includes six cylinders.
  • the inlet and outlet channels of a cylinder form a group and the geometric arrangement or shape of the inlet channels of a group is the same for all cylinders.
  • the internal combustion engine according to the invention comprises two, three, four or five valves per cylinder and one or two spark plugs per cylinder. There may be two, three or four camshafts per cylinder head installed.
  • the gas channels of the intake valves of a cylinder can be merged into one channel.
  • the use of two inlet valves and one outlet valve per cylinder has proven to be particularly advantageous. When using a plurality of exhaust valves per cylinder, it is also convenient to merge the belonging to the individual valves outlet channels of a cylinder to an outlet channel.
  • the internal combustion engine is installed with a transverse crankshaft in the motorcycle, which is also referred to as transverse installation. Then, the cylinder head covers a front cylinder row and a rear cylinder row.
  • the channels of a cylinder belonging to the inlet valves branch out of a common channel. If a plurality of exhaust valves are provided, then the exhaust ports of a cylinder belonging to the exhaust valves converge to form an exhaust duct.
  • the forward curved exhaust passages of the rear cylinder bank are arranged between the forwardly bent exhaust ducts of the front cylinder bank, wherein the exhaust duct of the outermost cylinder of the rear cylinder bank is arranged adjacent to the exhaust duct of the preceding cylinder of the front cylinder bank.
  • the cylinder head is designed with three camshafts.
  • the middle camshaft actuates the inlet valves of one cylinder bank and the exhaust valves of the other cylinder bank. These valves are then arranged inclined to each other.
  • the front camshaft operates only the exhaust valves of the front cylinder bank, the rear camshaft only the intake valves of the rear cylinder bank.
  • the valves can be operated directly via bucket tappets but also via rocker arms.
  • the intake ports of the front cylinder bank are located behind the middle and in front of the rear camshaft and the intake ports of the rear cylinder bank behind the rear camshaft.
  • all outlet channels open in the vehicle longitudinal direction at the front of the cylinder head and the mouths of the outlet channels of the rear cylinder row are offset from those of the front cylinder row in the vehicle longitudinal direction to the rear.
  • channel dimensions of the gas channels are the same for all groups.
  • the alignment of the channel groups for the front and the rear cylinder row may be the same, but it may also be mirrored.
  • all inlet channels can open at the top, center of the cylinder head, and the outlet channels open on both sides of the cylinder head.
  • all outlet channels can also run upwards in the middle and the inlet channels open laterally on both sides of the cylinder head.
  • the exhaust ducts bend bent to the side of the cylinder head, then they run under the camshafts, the in the flow direction are through, ie they are below the middle and the underlying camshaft when using three camshafts or only one of the two camshafts when using two camshafts.
  • the spark plugs are advantageously arranged centrally between the valves of the cylinder and project upwards.
  • camshaft 8 is arranged at the front transverse installation or left or right longitudinal installation.
  • camshaft 10 is arranged at the rear with transverse installation or left or right with longitudinal installation.
  • FIG. 1 shows the view of an embodiment of the cylinder head 1 of the six-cylinder Kraftradverbrennungskraftmaschine invention.
  • the cylinder head 1 has three camshafts.
  • the exhaust ports 2 extend below the middle and the front camshaft and open, if the engine is installed with transverse crankshaft (transverse mounting), in the vehicle longitudinal direction forward. With longitudinal crankshaft (longitudinal installation) open the outlet 2 channels left or right. All exhaust ports 2 are of the same geometry and dimensions and are directed forwardly (longitudinally to the side) with the exhaust ports 2 of the rear cylinder bank displaced rearwardly and opening between and adjacent to the intake valves 5 of the cylinders of the front cylinder bank.
  • All inlet channels 3 also have the same geometry and the same dimensions and project upwards and diagonally behind (with transverse installation) or opposite to the outlet channel openings (in longitudinal installation).
  • the inlet channels 3 and the outlet channel 2 of a cylinder each form a channel group 4.
  • the cylinder head 1 also comprises two inlet valves 5 and one outlet valve 6 per cylinder.
  • two groups each belong to one group of channels 4 to one unifying inlet channels and one outlet channel, which are indicated by three reference lines, respectively.

  • the intake ports 3 of the two intake valves 5 each branch from a common intake passage 3 from above.
  • the intermediate cam shaft 9 actuates the intake valves 5 of the front cylinder bank and the exhaust valves 6 of the rear bank of cylinders (in transverse installation).
