Definitions
- the invention is based on a multi-cylinder internal combustion engine according to the Features of the preamble of claim 1.
- the object of the invention is therefore to eliminate such negative consequences or to reduce and a uniform optimum cylinder filling level over the entire Cylinder row of the internal combustion engine to achieve.
- the object is achieved by the characterizing part of claim 1 specified characteristics solved.
- An optimization of the disadvantaged by the firing order cylinder is achieved when the narrower cams of the earlier exhausting cylinder one 10 ° to 20 ° CA per 1mm Valve lift has smaller cam width.
- FIG. 1 shows a sectional view of a V8 engine
- Fig. 2 is a schematic Representation of the two rows of cylinders of a V8 engine
- Figure 3 shows the firing order of a V8 engine with a partial representation of the charge exchange of three adjacent cylinders
- 4 is a schematic representation of a cylinder bank row
- Fig. 5 is a graphical Representation of valve lift curves and Fig. 6 with a different cam widths provided exhaust camshaft.
- the designed as a V8 engine internal combustion engine has one in a crankcase 10 arranged crankshaft 12.
- crankcase 10 At the offset with 90 ° KW arranged Crankshaft journals 14 are the Pleuelfworthe 16, of which only one visible is, screwed the connecting rod 18, which in turn via connecting rod 20 with the in the two cylinder bank rows arranged eight pistons 22 are connected.
- the two up Cylinder heads 24 fastened to the crankcase 10 take the for the 4-stroke combustion process on necessary and known components, wherein for all four arranged in a row cylinder find the same components use.
- Everyone Cylinder has two intake valves 26 and two exhaust valves 28, of which according to the sectional plane in Fig. 1 only one can be seen.
- the intake valves 26 monitor the leading to the combustion chamber 30 inlet channels 32, while the Exhaust valves 28 which also leading to the combustion chamber 30 exhaust ports 34th monitor.
- the four, flanged at each of the two rows of cylinder banks exhaust ports 34 are as 4-finger exhaust manifold formed after a short distance each in a open common exhaust pipe 36.
- the located on the suction side Inlet channels 32 are connected via an unillustrated intake system with combustion air provided.
- the actuation of the intake and exhaust valves 26, 28 takes place by means of a Intake camshaft 38 and exhaust camshaft 40.
- the intake and exhaust ports Exhaust camshaft 38, 40 each have four pairs of intake cams 42 and Exhaust cam 44, wherein the cylinder specific special training of the cam will be described later in more detail.
- valve springs 50, 52 is u.a. made sure that the Inlet and exhaust valves 26, 28 during the basic phase of the cams 46, 48 the Inlet or outlet channel 32, 34 securely close.
- injectors 54 Fuel is injected into the intake ports 32, which when opening the intake valve 26 with Help an ignition device designed as a spark plug 56 in the combustion chamber 30 to Combustion is brought.
- the firing order is distributed on the two rows of cylinder banks arranged cylinders 1 to 4 or 5 to 8 shown.
- the firing order based on the two rows of cylinder banks asymmetrical and has three different firing intervals per cylinder bank row.
- the ignition interval is 90 ° CA, between the cylinders 2 and 3 and 1 and 4 180 ° KW and between cylinders 2 and 4 270 ° KW.
- this is the Zündzeitticianabpartie in the second row of cylinders 5 to 8 between cylinder 5 and 6 90 ° KW, between cylinder 6 and 7 and between cylinder 5 and 8 180 ° KW and between cylinder 7 and 8 270 ° KW.
- the distance by 180 ° KW exhaust cylinders 1 and 3 or 1 and 4 within the cylinder row 1 - 4 and the Cylinders 6 and 7 or 5 and 8 within the row of cylinders 5 - 8 have the from Air effort ago disadvantaged cylinder 3, 4, 5, 7 a larger cam width for on the exhaust camshaft 40 arranged on cam 44.
- Fig. 5 is with the left solid curve A, the valve lift for the exhaust valves 28 of the cylinder 3, 4, 5th 7, while the smaller valve lift curve shown in dashed lines A 'is associated with the exhaust valves 28 of the cylinders 1, 2, 6, 8.
