Number limit ob./minute
6300 – 6500
Delay of giving of fuel by means of change направляения an operating current in a pressure difference regulator
The throttle switch
Switching points:
The switch I – the mode switch холотсого a course
0.15 – 0.5 mm between a point of operation of the switch and a stop of the lever of a throttle
The switch II – the mode switch completely open throttle заслонки
10 ° ± 2 ° to a full stop


Pressure in system

6.1 – 6.5 bar (manometrical pressure)

Pressure difference:
1 – the electrosocket is disconnected from a pressure difference regulator Approximately 0.3 – 0.5 bar below pressure in system
2 – the electrosocket is connected to a pressure difference regulator (include a starter approximately for 3 seconds) Approximately 1.3 – 1.6 bar below pressure in system
Residual pressure:

After at least 10 minutes

3.3 bar (manometrical pressure)
After at least 20 minutes 3.2 bar (manometrical pressure)
Fuel injectors:
Working pressure 3.7 – 4.8 bar (manometrical pressure)

Maximum deviation of quantity of injected fuel in a set of injectors:

Measurement in an idling mode (a position of 1 tool 1348/1) at quantity of injected fuel of 20 ml Maximum of 2.0 ml
Measurement in a mode completely open throttle заслонки (a position 2 tools 1358/1) at quantity of injected fuel of 80 ml Maximum of 8.0 ml
Resistance of a regulator of pressure difference 15 – 20 Ohm
Example 1: 2500 Ohm at 20 ° With  

Example 2: 200 Ohm at 100 ° With

 
Resistance of the valve of start from a cold condition About 10 Ohm
