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

Top Dead Point (TDP) calls the highest point of a blow of piston in the cylinder. Properly I dictate, in motors of 4 blows in the course of the rotation of an end of inclination this situation is got by each one of pistons two times: once in the end of a step of compression and the second – in the end of a step of launch. In artistic proceedings of the control and agreement of the position of motor of the piston of the first cylinder in VMT of the end of a step of the compression it is in use in most of the cases.

The necessity of the reduction of the piston in the provision of VMT appears maintaining many proceedings, specially like service of the mechanism valvate, removal and installation of the axle, component of GRM drive, etc.

ORDER OF REALIZATION

One secure what the transmission transfers to the neutral situation, soon lift the brake of parking or support behind wheels of the car you put that you were antishowing. The separate captures of an electrical system of rolls of the ignition and they turn out to be taken of spark (seen the Check of Section e a substitution of captures of spark).
The reduction of some of pistons in the provision of VMT is made by a provorachivaniye of an end of inclination of the motor in the normal direction of the rotation through a face key with the walk of catraca (in the direction of the movement of the pointers of the clock) from the pin screwed in a face of end of an advanced pin of an end of inclination. In the presence of the spectator, the preliminary provorachivaniye of the motor can be executed by an author (breaks of the short enemy lines) of the place of the driver below the leadership of the operator.
If the head of cylinders is not discovered, result when they were taken of spark and establish компрессометр in an opening of candle of the first cylinder (to see the Section of the Door).

Kompressometr has to be ended with a woodcarving mouth with a hose of not less than 15 cm of longitude that is joined.

Become an end of inclination so that it carves it in his pulleys drive was coinciding with the mark "0" in a covering of belt of GRM. At the same time the piston of the first cylinder is going to happen in VMT.

It is possible to secure what VMT of the end of a step of the compression gets, to look at the indications of the kompressometr – in the moment of the approximation of VMT of the end of a step of the pressure of compression will begin growing in the cylinder considerably. If the head of cylinders is discovered, it is possible to be secured of the realization of VMT of the end of a step of the compression, looking empurradores of all the valves of the first cylinder – there will be free edges, this is of work of the corresponding cames of axles they have to be raised.
If VMT of the end of a step of the launch is got, then in VMT of the end of a step of the compression there become the reduction of the piston an end of inclination in the normal direction in a whole revolution.
