Reduction of the piston of the first cylinder in the provision of the top dead point (TDP)

The description of procedure given below is made on the basis of the assumption of correctness of connection of VV of candle wires and installation of the distributor of ignition. If there is a need of reduction of the engine for VMT for the purpose of updating of the provision of the distributor, position of the piston in the first cylinder of the engine can be qualitatively defined by tracking of change of compression pressure through a candle opening. Further it is necessary to achieve combination of the corresponding adjusting tags.

The highest point of a piston stroke in the cylinder is called as the Top Dead Point (TDP). Strictly speaking, in 4-stroke engines in the course of rotation of a cranked shaft this situation is reached by each of pistons twice: once at the end of a step of compression and the second - at the end of a final step. During the performing of settings of phases of gas distribution and installation of a corner of an advancing of ignition the provision VMT of the end of a step of compression of the piston is in most cases used (usually the first cylinder).

Need for reduction of the piston(s) in situation VMT arises when carrying out many procedures, in particular such as removal/installation of a camshaft, components of the GRM drive and distributor of ignition.

Make sure that transmission is transferred to neutral situation, then strongly cock the parking brake, or prop up back wheels of the car antiretractable boots. Also immobilize system of ignition, having disconnected VV a coil wire from a cover of the distributor and having grounded it on the engine block a wire crossing point. Turn out spark plugs (see the Head Nastroyki and routine maintenance).

Reduction of any of pistons in situation VMT is made by a provorachivaniye of a cranked shaft of the engine by one of the ways described below. If to look at the engine in front (from a driving belt), the direction clockwise will be the normal direction of rotation of a cranked shaft:

a) By the most effective method a shaft yavlyaetsyaprovorachivaniye in the normal direction for the bolt screwed in an end face of its forward pin by means of a face key with the ratchet drive - remove the lower filter from the passenger party of the car;
b) Use of the remote switch of a starter will allow to save time (follow instructions of manufacturers). As soon as the piston appears rather close from VMT of the end of a step of compression, the starter stops and further adjustment is carried out by the method described in point (and);
c) In the presence of the assistant, the preliminary provorachivaniye of the engine can be carried out by short breakthroughs from a driver's place under the leadership of the operator. The same principle, as described in point (b). Final adjustment, besides, is made manually, by means of a face key (see point and).

 PERFORMANCE ORDER

1. Remember position of the plug of connection of a candle wire of the first cylinder on a distributor cover.

2. If the plug is not marked, walk on a wire from a candle to a cover and put the corresponding tag independently (use a chertilka or a marker).

3. Uncover the distributor and put it aside (see the Head Nastroyki and routine maintenance).

4. Turn a cranked shaft clockwise so that the white tag of VMT on its pulley was combined with the triangular index on a cover of a gas-distributing belt.

On a pulley there are two adjusting tags. The second tag is put with red paint and serves only for installation of a corner of an advancing of ignition by means of a stroboscope.

5. Now check position of the runner of the distributor, - it has to appear the developed nose precisely on a tag on a case rim. If the runner is deployed concerning a tag on 180 °, therefore, the piston of the first cylinder is in the provision VMT of the end of a final step. To bring the piston into VMT of the end of a step of compression, it is necessary to turn a cranked shaft on one complete revolution (360 °) counterclockwise. Now the runner has to be deployed by a nose to a tag.

6. Weaken the screw and put a viewing cover aside, having provided thereby access to adjusting tags on cogwheels of camshafts of both rows of cylinders. Through an opening make sure of a cover of a gas-distributing belt that the adjusting tag on a cogwheel of a camshaft is combined with a reciprocal tag on a back cover.

7. When all tags (on a pulley of a cranked shaft and a cogwheel of a camshaft) are combined, the piston of the first cylinder can be considered brought to the provision VMT of the end of a step of compression.
8. Now, that serially, as ignition to bring the remained pistons into VMT, the cranked shaft should be turned clockwise with a step in 120 °, passing from the cylinder to the cylinder as ignition. Put the corresponding tags on a distributor case rim (as it was done higher for the plug of connection of the first candle wire). Provorachivaniye of a cranked shaft will be inevitably followed by rotation of the runner which combination of a nose with the corresponding tag and will be confirmation on reduction of the next piston in VMT of the end of a step of compression.
