Definitions
- the invention relates to a method for synchronizing an internal combustion engine according to the preamble of patent claim 1.
- signals from camshaft and crankshaft sensors are usually processed in an engine control unit.
- DE 39 14 169 C2 discloses a cylinder locking device for an internal combustion engine for controlling the ignition device at least in terms of the cylinder, in which scanning a crankshaft disk, which has the same markings for the top dead centers of all cylinders, and a camshaft disk, which has a separate marking for each cylinder, correct ignition should also be guaranteed at the start.
- DE 196 38 010 AI describes a method for determining the phase position of a four-stroke internal combustion engine with an odd number of cylinders by comparing the signal of a crankshaft sensor, which has a singularity to be assigned to a predeterminable crankshaft angle, with a second signal of a speed sensor or intake manifold pressure sensor, in the area this singularity.
- EP 0 640 762 discloses a method for synchronizing an internal combustion engine, which can carry out the synchronization without a camshaft sensor, only with a crankshaft sensor. However, this method can only be used in internal combustion engines with an even number of cylinders.
- the object of the invention is to provide a method for synchronizing an internal combustion engine with an odd number of cylinders.
- the signals KW of a crankshaft sensor (line a), the piston positions of the three cylinders ZI to Z3 (lines b) of a three-cylinder engine, and the piston positions of the five cylinders ZI to Z5 (line c) of a five-cylinder engine in the course of one engine cycle lasting over two revolutions (2 * 360 ° KW) of the crankshaft (not shown) of the internal combustion engine.
- the connecting rods of the three pistons of the three-cylinder engine are offset from each other by 120 ° KW on the crankshaft.
- the connecting rods of the five pistons of the five-cylinder engine are offset from each other by 72 ° KW on the crankshaft.
- the crankshaft sensor consists of a sensor wheel, not shown, connected to the crankshaft, which is, for example, a gearwheel with 60 teeth, two teeth of which are removed and form a gap L.
- a sensor not shown
- the gap L ends precisely when the piston in the cylinder ZI reaches its top dead center ZOT1.
- ZOT2 of the cylinder is Z2 by 240 ° KW
- the ZOT of each cylinder is identified by a thick dotted line, as well the standstill points ST1 to ST3 of the individual pistons are marked in their cylinders by a thick solid line.
- crankshaft must be rotated further by 120 ° + X ° until the crankshaft sensor detects the next gap, i.e. the end of it. If the piston in the cylinder Z3 came to a standstill at X ° before Z0T3, the crankshaft must be rotated further by 240 ° + X ° until the crankshaft sensor detects the next gap, i.e. the end of it.
- Selective fuel injection and ignition then begin in the firing order of the cylinder following the synchronized cylinder, which can still be reached for fuel injection. This can vary depending on the fuel injection method (intake manifold injection before or during the intake stroke or direct injection).
- the cylinders are arranged at a distance of 72 ° on the crankshaft. This means that when restarting the crankshaft must be rotated by X ° until the crankshaft sensor detects the next gap when the piston in its cylinder, to which the gap of the crankshaft sensor is assigned, stops by X ° before its ZOT came, here in the cylinder ZI at X ° before ZOT1.
- Selective fuel injection and ignition also start here in the ignition sequence of the cylinder following the synchronized cylinder, which can still be reached for a fuel injection.
- the internal combustion engine can be synchronized without a camshaft sensor within ⁇ 360 ° KW, that is, during the first crankshaft revolution after a restart.
- the method can also be applied to engines with even more cylinders. Such motors have not yet been used in motor vehicles.
