Definitions
- a position transmitter additionally delivers a position signal with a reference pulse per revolution of the crankshaft, by means of which a known angular position, the synchronization position, is determined. Only when the reference pulse is recognized, in conjunction with the position signal, is the position of the cylinders of the internal combustion engine known exactly, and a synchronization of electrical control functions - ignition, injection, etc. - and the cylinder positions is possible (synchronization time).
- the time for this injection can be immediately after the signal change, which has the advantage that no additional arithmetic operation is necessary after the signal change has been detected. As with the first cylinder group, this largely avoids injecting fuel into an open intake valve of a cylinder.
- a crankshaft encoder KG with a reference mark RM in conjunction with an assigned crankshaft scanner KA serves as the position encoder PG.
- This delivers a reference pulse R per revolution of the crankshaft, which determines a synchronization position.
- the falling edge of this reference pulse R is 84 ° before each top dead center of the cylinder 1.
- the signal change of the position sensor lies in the middle between two such reference pulses R. This distance is an empirical value for which a particularly favorable signal processing results in a very specific internal combustion engine .
- the preliminary quantity is injected into the second cylinder group assigned to the B signal with cylinders 2, 3 and 4.
- the inlet valve of cylinder 4 is still open for a short time.
- a fourth operating case - D in FIG. 3 - the instant t3 of the start detection is in the range of the B signal, so that cylinders 2, 3 and 4 of the assigned cylinder group receive the preliminary quantity at the same time.
- the reference pulse R follows again before the next signal change of the position signal, so that cylinders 1, 5 and 6 of the next cylinder group receive the preliminary quantity sequentially. With cylinder 1 the sequential injection starts with normal quantity.
