Reduction of the piston of the first cylinder in the provision of the top dead point (VMT)
The highest point of a piston stroke in the cylinder is called as the top dead point (VMT). Strictly speaking, in 4-тактных 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. At performance of settings of phases of a gazoraspredeleniye and installation of a corner of an advancing of ignition in overwhelming majority of cases the provision VMT of the end of a step of compression of the piston (usually the first cylinder) is used. Need for piston reduction (it) in situation VMT arises at carrying out many procedures, in particular such, as removal/installation of a camshaft, components of a drive of GRM and the ignition distributor. Make sure that transmission is transferred to neutral situation, then strongly cock the parking brake, or prop up back wheels of the car protivootkatny boots. Also immobilize ignition system, having disunited electric sockets of primary (NV) of a contour of the coil (see. Head engine Electric equipment). Remove spark plugs (see. Head of Control 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 described below ways. If to take a detached view of the engine in front of (a driving belt), the direction counter-clockwise will be the normal direction of rotation of a cranked shaft. Remember that attempt of a provorachivaniye of a shaft clockwise can lead to violation of adjustments of a gas-distributing belt. a) The most effective method is the shaft provorachivaniye in the normal direction for a bolt screwed in an end face of its forward pin by means of a face natural by a ratchet drive; b) To save time use of the remote switch of a starter (follow instructions of manufacturers) will allow. As soon as the piston will appear rather close from VMT of the end of a step of compression, the starter stops and further adjustment is carried out by a 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 direction 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).
