GENERAL INFORMATION

Prevention

Before check the engine has to be heated-up, the moment of ignition is adjusted, and gaps in valves to meet standard (except for self-regulating valves). All consumers have to be disconnected.


Carburetor engines

PERFORMANCE ORDER
1. Connect a tachometer and a gas analyzer.
2. Warm up the engine and transfer to idling.
3. Adjustment of turns is allowed only on carburetors 2B4. The special screw is for this purpose provided (in the photo).
4. If on the engine with the carburetor 2 turns low and conducting is correct, then it is possible to raise them connection of the additional resistor in a chain of management (it is carried out in BMW car service).
5. Quality of mix is regulated by the special screw (it is specified by figure 2).

System of injection L-Jetronic

The special tester WITH which sensor is rolled in a final collector is necessary for check (it is allowed to use the analyzer with the probe which is entered into an exhaust pipe, however on models with converter this device will not yield the acceptable results).

PERFORMANCE ORDER
1. Turns of idling are regulated by the screw on a throttle branch pipe (previously it is necessary to remove a screw cap).
2. Quality of mix (SO) is regulated by the screw on the stream measuring instrument a special key of BMW 13 1 060.

System of injection Motronic

The special tester WITH which sensor is rolled in a final collector is necessary for check (it is allowed to use the analyzer with the probe which is entered into an exhaust pipe, however on models with converter this device will not yield the acceptable results).

PERFORMANCE ORDER
1. If turns of idling differ from normal (adjustment is provided with automatically processor block), then check tightness of a joint of an inlet collector and also the air regulator of idling.
2. Quality of mix (SO) is regulated by the screw on the stream measuring instrument a six-sided key.
3. Remove a zagleshka of the adjusting screw on the stream measuring instrument.
4. Adjust WITH.
5. Put a cap into place.
