Check and adjustment of turns of idling and prevention spontaneous останова engine

THROUGH EACH 20 000 KM (12 000 MILES) RUN

The tachometers of usual type working from pulse signals of system of ignition at diesel engines are not applicable. Special I will corrode serves for connection of the firm diagnostic equipment of Citroёn, for obvious reasons of the average amateur mechanic absent in an arsenal. At emergence of suspicions on violation of installation of turns of idling (aurally) it is necessary to try to get a special tachometer, or to drive away the car on car repair shop firm Citroёn company service center.

Before starting adjustments the engine it is necessary to warm up to normal working temperature. Make sure of correctness of adjustments of cables of gas and management of turns of fast idling (see. A power supply system - diesel models).

Adjustments of TNVD of production of the Lucas company

1 — the Screw of adjustment of the maximum turns
2 — the Screw of adjustment of turns of fast idling
3 — a pump Control lever
4 — the Screw of adjustment of turns of prevention spontaneous останова the engine.
5 — the Cable of management of turns of fast idling

6 — the Tip of a cable of management of turns of fast idling
7 — the Control lever turns of fast idling
8 — the Screw of adjustment of turns of idling
9 — the Lever manual останова the engine
And — the Installation site of an adjusting washer of prevention spontaneous останова the engine
In — the Adjusting screw of a cable of gas


 PERFORMANCE ORDER

1. Establish an adjusting washer of the demanded thickness (see. Specifications) between a control lever of the pump and the screw of adjustment of turns of prevention spontaneous останова the engine (see an illustration of Adjustment of TNVD of production of the Lucas company).
2. Delay the lever manual останова the engine back against the stop and fix it in this situation, having passed a 3-millimetric core (the drill of the corresponding diameter will approach) through an opening in a control lever turns of fast idling.
3. Turns of the engine should accept the value corresponding to frequency predotvrashcheniyasamoproizvolny останова (see. Specifications).
4. In case of need performance of adjustment weaken a screw (4) lock-nut (see an illustration of Adjustment of TNVD of production of the Lucas company) and start to rotate in the corresponding direction, achieving satisfactory result. On termination of adjustment do not forget to tighten a lock-nut.
5. Take a lock core (drill) and an adjusting washer and make sure that turns of the engine decreased to single (see. Specifications).
6. In case of need weaken a lock-nut of the screw of adjustment of turns of idling and make necessary adjustment, rotating the last in the corresponding direction. Having achieved satisfactory result, tighten a lock-nut.
7. Having shifted a pump control lever, lift frequency of rotation of the engine to value of 3000 rpm, then quickly release the lever. Duration of a deseleratsiya should make from 2.5 to 3.5 seconds, and frequency of rotation of the engine should fall to value on approximately to 50 rpm is lower than the single.
8. If the deseleratsiya occurs too quickly, and the engine глохнет, turn out the adjusting screw of prevention spontaneous останова on a turn quarter in the control lever direction. Too slow deseleratsiya reduces efficiency of braking by the engine. In this case it is necessary to return the adjusting screw, on the contrary, on a turn quarter, having taken away it from the lever.
9. Having finished adjustment do not forget to tighten a lock-nut, then once again check installation of turns of idling, in case of need adjust them repeatedly (see above).
10. On the engine working at single turns check serviceability of functioning of the lever manual останова, having turned it clockwise (see. A power supply system - diesel models). The engine should decay at once.
11. Disconnect a tachometer.

Models without a turbo-supercharging

 PERFORMANCE ORDER

1. Weaken a lock-nut and turn out the adjusting screw of turns of prevention spontaneous останова the engine so that it left contact to a pump control lever (see an illustration of Adjustment of TNVD of production of the Bosch company).
2. Weaken a lock-nut and rotation of the screw of adjustment of turns of idling make necessary adjustment. Do not forget to tighten a lock-nut again.
3. Fill an adjusting washer or an edge щупа the corresponding thickness (see. Specifications) between a control lever the pump and the screw of turns of prevention spontaneous останова.
4. Start the engine on single turns. Frequency of its rotation should appear equal to the value corresponding for turns of prevention spontaneous останова.
5. In case of need weaken a lock-nut and screw (5) rotation (see an illustration of Adjustment of TNVD of production of the Bosch company) make the corresponding adjustment (see. Specifications).
6. Take an adjusting washer / щуп and allow to fall a turn of the engine to the single.
7. Shift a control lever turns of fast idling against the stop forward and make sure that frequency of rotation of the engine rose to the value stipulated for fast idling (see. Specifications). In case of need weaken a lock-nut and rotation of the adjusting screw (1) make the corresponding adjustment. Not to tighten a lock-nut.
8. On the engine working at single turns check serviceability of functioning of the lever manual останова, having turned it clockwise (see. A power supply system - diesel models). The engine should decay at once.
9. Disconnect a tachometer.

Models with a turbo-supercharging

 PERFORMANCE ORDER

1. Execute the procedures described in subsection "Models without турбонадува", subitem 1 — 6.

2. Weaken a lock-nut and turn out the adjusting screw of a damper of the control lever, located behind the last.
1 — the Lock-nut
2 — the Adjusting washer
3 — a damper Rod
4 — the Adjusting screw
5 — a pump Control lever

3. Fill an adjusting washer or an edge щупа between a rod of a damper and the adjusting screw. Make sure that the control lever of the pump occupies the situation corresponding to single turns of the engine, then rotation of the adjusting screw achieve, that the washer / щуп with easy resistance sliped in a gap between the screw and a rod. Fix the screw in this situation, having strongly tightened a lock-nut.

4. Execute the procedures described in the section "Models without турбонадува", subitem 6 — 9.
