In this mode, the block receives the following information.
- Message from the block (N73) whether the A/C compressor is on or off.
- Signal about the position of the automatic transmission selector from the gear selector block (N15/5)
- Engine speed signal on a separate circuit (L5).
- Coolant temperature sensor signal on a separate line (B11/4).
- Accelerator pedal sensor signal via CAN-C multiplex network (At 37/3).
- Engine speed signal on a separate circuit (L5) to compare the current speed value with the set value.
In order to ensure optimal combustion of the fuel, injection can be carried out in three stages.
- Pre-injection.
- Main injection.
- Final stage of injection.
The essence of this improvement is that with a large cycle amount of fuel and a low engine speed, "tough" combustion of fuel, too fast combustion process. In order to coordinate the rate of fuel combustion with the speed and load on the engine, the injection process is divided into several stages. However, under certain conditions (see below) the division of the process into stages may not be carried out.
