60chsm2n Fig. 7
The crankshaft position sensor B231 indicates the
engine's rotation speed, as well as the precise crankshaft
position (TDC of cylinders 1 and 6). This signal is hence
used by engine speed and advance management.
The timing position signal "B232" specifies which cylinder,
1 or 6, is at end compression TDC to synchronize injection
with timing.
If the signal transmitted by "B231" is absent, the signal
transmitted by "B232" is used to manage engine speed.
As the crankshaft position information is inaccurate, a
power reduction is indicated.

Injector command
The injectors are piloted by transient electric pulses.
Depending on the case, combustion may require 1 or 2
pulses (pre-injection + main injection).

Operating summary
The supply pump generates a pressure of about 0,3 bar,
regardless of the load or engine speed during operation.
Each injector has its own command element "Y320".
The engine module "ENG A15" commands injection on a
cylinder, by selecting the appropriate solenoid valve
"Y320".
