- Outlet channel and at least one inlet channel comprises, and wherein the geometric arrangement of the inlet channels of a group is the same for all cylinders.
- Inlet channel at an intake valve or the intake ports are the same for all cylinders of a plurality of intake valves of a cylinder.
- the intake passages in the cylinders of the rear cylinder bank may be aligned in the same direction as the intake passages of the front bank of cylinders, but they may also face each other
- Gas channels in the front and rear cylinder rows can be used to achieve the same flow conditions for all cylinders, ensuring smooth engine operation over the entire engine speed range. With the same shaped use
- Inlet ducts on all cylinders a high engine performance and the greatest possible synchronization and smoothness of the engine is achieved.
- a further solution according to the invention describes claim 2 such that with transverse crankshaft (transverse mounting), the inlet channels of the rear cylinder row behind the rear camshaft and the inlet channels of the front cylinder row are arranged in front of the rear camshaft or at longitudinal
- Camshaft are arranged.
- the arrangement of the inlet channels described on both sides of the intake-side camshaft ensures that
- Inlet ducts are used with the same length and the same shape, which are also relatively short, which also a high engine performance and the greatest possible synchronization and smoothness of the engine is achieved.
- the engine comprises six cylinders.
- a favorable development of the solution according to claim 2 is also that with several identical valves per cylinder, the inlet channels 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 geometric arrangement (shape) of the outlet channels of a group is the same for all cylinders.
- Internal combustion engine 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.
- the internal combustion engine is installed in a configuration with a transverse crankshaft in a motorcycle, which is also referred to as transverse installation. Then it covers
- Cylinder head a front cylinder row and a rear cylinder
- 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 inlet channels protrude upwards and the outlet channels are bent to one side or at
- Cylinder row are also between the bent forward
- Outlet ducts of the front row of cylinders arranged, wherein the outlet channel of the outermost cylinder of the rear row of cylinders adjacent to the outlet channel of the front of the cylinder
- front cylinder bank is arranged.
- the cylinder head can be designed with one, two or three camshafts, the versions with two or three
- Camshafts are particularly favorable. With three camshafts, the middle camshaft actuates the intake 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 row, the rear camshaft only the intake valves of the rear cylinder bank.
- the valves are operated directly via bucket tappets or via rocker arms.
- the intake ports of the rear cylinder bank are behind the rear camshaft and
- Channel groups are all six inlet channels between the two camshafts arranged and protrude upwards.
- Cylinder head and the mouths of the outlet channels of the rear row of cylinders are offset from those of the front row of cylinders 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. In mirrored arrangement of the groups can all intake ports at the top, center out of the cylinder head and the exhaust ports open on both sides of the cylinder head. Conversely, all the outlet channels can also run upwards in the middle and the inlet channels on both sides of the
- Exhaust ports are then under the center and front camshafts when using three camshafts or just below the front camshaft when using two camshafts.
- the spark plugs are advantageously arranged centrally between the valves of the cylinder and project upwards.
- the internal combustion engine according to the invention comprises cylinders in W arrangement, in which case four rows of cylinders are present, each with a cylinder head for two rows of cylinders, as a total of two cylinder heads.
- FIG. 1 view of the cylinder head from the front and from above
- FIG. 7 view of a cylinder head with 2 camshafts and both sides opening outlet channels
- FIG. 1 shows the view of an embodiment of the invention
- Cylinder head 1 of the internal combustion engine according to the invention with six cylinders.
- the cylinder head 1 has three camshafts.
- the exhaust ducts 2 extend below the middle and the preceding camshaft and open to the front or to one side of the cylinder head. All outlet channels 2 have the same geometry and the same dimensions and are directed forward, the outlet channels 2 of the rear row of cylinders are offset to the rear and between or beside the
- Inlet valves 5 of the cylinders of the front cylinder bank open. All intake ports 3 also have the same
- Outlet channel mouths (for longitudinal installation).
- the inlet channels 3 and the outlet channel 2 of a cylinder each form one
- the cylinder head 1 also includes two
- Intake valves 5 and one exhaust valve 6 per cylinder Intake valves 5 and one exhaust valve 6 per cylinder.
- two groups each belong to one group of channels 4 to one unifying inlet channels and one outlet channel, which is indicated by three reference lines.
- the too The inlet channels 3 belonging to the two inlet valves 5 of a cylinder unite into an inlet channel 3, which is led upwards.
- Cylinder row are guided behind the rear camshaft 10 upwards
- the inlet ducts 3 of the front cylinder bank are guided behind the central camshaft 9 and in front of the rear camshaft 10 upwards.
- the exhaust ducts 2 of the rear cylinder bank are arranged below the middle and front camshafts 8, 9 and are led forward under these two camshafts.
- Camshaft drive is arranged on one side. All valves are operated by bucket tappets directly from the camshafts. The spark plugs 7 are each centered between the two
- Inlet valves 5 and the exhaust valve 6 are arranged.
