Keeping pressure after switching-off of ignition after 5 minutes	min 0,5 bar
Vprysknaja atomizer
Resistance of an atomizer at environment temperature (15 – 30C)	1,2 – 1,6 Ohm
Frequency of rotation in an idling mode (is not regulated)	750 – 1000/mines
The maintenance WITH (is not regulated)	0,2 – 1,2 %
System of injection Digifant
Engine marks	ABK
Pressure of fuel at frequency of rotation in an idling mode
The disconnected vacuum tube	Apprx. 2,5 bar
The connected vacuum tube	Apprx. 3,0 bar
Keeping pressure after switching-off of ignition after 10 minutes	min 2,0 bar
Vprysknaja atomizer
Resistance of an atomizer	2 – 10 Ohm
Frequency of rotation in an idling mode (is not regulated)	820 50 rpm
The maintenance oxide carbon (it is measured in a CO-measuring tube)	0,6 0,4 %
Level of height over 300 m on 100 m of increase in height	доб. 0,2 %
System of injection KE-III-Jetronic
Engine marks	NG
Pressure in system	6,1 – 6,5 bar
Difference of pressure
The tip is disconnected from a pressure regulator	Apprx. 0,3 – 0,5 bar below pressure in system
