Test and Adjustment Data

Table I Fuel Pressures

System pressure	with engine cold or at operating temperature	bar 6.2 - 6.4
Lower chamber pressure	with engine at operating temperature	bar approx. 0.4 1)
	at idle with coolant temperature < + 20 oC	bar 0.5 1)
	during deceleration shut-off	bar Lower chamber pressure equals system pressure.

1) Observe Preparation for Test, see 22 .

Table II Current Values

Engine	Current at EHA with Ignition: ON (mA)	After-start enrichment at an engine coolant temperature of + 20 oC (mA) 1)	After-start enrichment at an engine coolant temp. between 0 and + 20 oC (mA) 1)	After-start enrichment at an engine coolant temp. between 0 and - 20 oC (mA) 1)
104	20	3 - 5 2)	3 - 45 3)	38 - 80 3)
119	75	5 - 8 2)	5 - 42 3)	42 - 100 3)

1) For resistance substitution unit resistance values, see 23 , Table I. 2) Read value 0 - 8 seconds after startup. 3) Note the following: Read value immediately after startup. Selector lever position P/N. Throttle valve closed.
