Definitions
- the invention relates to a multi-cylinder internal combustion engine according to the preamble of claim 1.
- the invention has for its object an internal combustion engine to create the generic type, in which the Combustion chambers and the intake and exhaust channels of all cylinders can also be formed identically, in which but cylinder-selective fuel injection is no problem provided and the heating of the aspirated mixture can be kept low, more than two Intake valves can be provided per cylinder and finally, an optimal guidance of the outlet channels is realized is.
- each inlet duct an injection valve with spray direction on the or to provide associated intake valves. Because the Inlet channels are on the outside, heating of the intake Mixtures avoided or at least reduced. Due to the external arrangement of the inlet valve rows there is also the possibility of taking up little space to provide long intake ports, reducing torque is increased in the lower speed range. Finally, you can in that each intake camshaft only the intake valves actuated in a row of cylinders on each intake camshaft more than two cams can be accommodated per cylinder, so that easily with an internal combustion engine, for example three intake valves per cylinder can be realized.
- the drive element is with connected to the exhaust camshaft and the output element is preferably over one with both intake camshafts Chain gear connected, the output element of the Adjustment device and the intake camshafts sprockets have the same diameter.
- the diameter of this Sprockets can be significantly smaller than that on the Exhaust camshaft seated, with the crankshaft in drive connection stationary drive wheel, with which the width of the cylinder head, which depends largely on the diameter of the sprockets seated on the intake camshafts is reduced. Naturally, this is particularly important when installing such an internal combustion engine in the engine compartment of a motor vehicle.
- the cylinders are arranged in two rows, the cylinders 1 of the one row to the cylinders 2 of the other row stand on a gap and the longitudinal central axes the cylinder of one row with the longitudinal central axes the cylinder of the other row makes an angle include, as can be seen from Fig. 2.
- the cylinder head 3 contains 1 of the first for each cylinder Row of cylinders three intake ports 4 by a common intake port 5 go out and open into inlet openings 6, which are dominated by inlet valves 7. Each cylinder 1 the first row of cylinders are also two exhaust ports 8 assigned, which combined into a collective outlet channel 9 are and start from outlet openings 10, which of Exhaust valves 11 are controlled. In a similar way are three for cylinders 2 of the second cylinder bank Inlet channels 4 'are provided, which open into inlet openings 6', which are controlled by inlet valves 7 ', and two outlet channels 8 ', which start from outlet openings 10', which are controlled by exhaust valves 11 '.
- the exhaust valves 11, 11 'of all cylinders 1, 2 are each in two extending in the longitudinal direction of the machine Exhaust valve rows A and B arranged, which to both Sides and close to that between the rows of cylinders Plane of symmetry S lie.
- the exhaust valves 11, 11 ' Both cylinder rows are over the tappet 12 from the Actuated cam 13 of a common exhaust camshaft 14, which lies in said plane of symmetry S.
- the intake valves 7, 7 'of the two rows of cylinders are arranged on the outside and are each created by the cams of their own, external intake camshaft 15 and 15 'actuated.
- the Exhaust camshaft 14 carries a drive wheel 16, which with the Crankshaft in drive connection.
- This known adjustment device is shown in detail in Fig. 3 and has a sleeve-shaped Drive element 18 on that with the drive wheel 16 in one piece and with the exhaust camshaft 14 rotatably connected is.
- the adjusting device 17 also has an output element 19 on the inside of the drive element 18 rotatably mounted on the exhaust camshaft 14 is and carries an output gear 20, which by a Chain 21 with arranged on the intake camshafts 15, 15 ' Sprockets 22, 22 'are in drive connection.
- the drive element 18 has an internal longitudinal toothing 23 and the output element 19 is with an outer Provide helical teeth 24. Between the drive element 18 and the output element 19 is an annular adjusting piston 25 arranged, the one with the toothing 23rd engaging spur gear 26 and one with the Gearing 24 helical gearing 27 engaged having. As a result, the drive element 18 is rotatably fixed connected to the output element 19. By moving the Adjusting piston 25 can be the angular position of the output element 19 compared to the drive element 18 and thus the Angular position of the intake camshafts 15, 15 'opposite the exhaust camshaft 14 can be changed. The adjustment of the adjusting piston 25 takes place against the force of one Spring 28 by pressurizing the left face of the adjusting piston 27. Such an adjusting device is described for example in DE-A 29 09 803.
- the inlet valves 7, 7 ' are in the embodiment Rocker arm operated, with variable valve timing is provided with which a different actuation in a lower and an upper speed range can.
- a variable valve control is described for example in DE-A 42 05 230.
- a first cam 30 intended for the lower speed range, which with a first rocker arm 31 cooperates, which on the corresponding Inlet valve 7 or 7 'acts.
- the first rocker arms 31 can be used with the second rocker arms 33 are coupled by coupling bolts 34, whereby then the intake valves according to the contour of the second cam 32 are actuated.
- All first and second Rocker arms 31, 33 for the intake valves of a row of cylinders are mounted on a common axis 35, the contains a channel 36 through which a pressure medium is supplied can be that the coupling pin 34 against the Force a spring 37 in the clutch position.
- the inlet manifolds extend 5 outwards and upwards to the top 37 of the Cylinder head.
- Each inlet manifold 5 is an injection valve 38 assigned that towards the three Inlet valves 7 and 7 'injected.
- On the top 37 of the A cylinder head cover 39 is placed on the cylinder head 3.
- the inlet manifolds 5 sit in channels 40 in the Cylinder head cover 39 continues with a not shown Intake manifold are connected.
- the sprockets 20 and 22, 22 ' have the same diameter. This diameter can be smaller than the diameter of the exhaust camshaft drive wheel 16. This can Overall width of the cylinder head 3 in the area of the camshaft drive, which depend largely on the diameter of the gears 22, 22 'is determined to be kept relatively small.
