3.4.8.1. Engine diagnostics by means of the vacuum gage
Measurement of depression is reliable and rather cheap way of diagnostics of the engine. According to indications of the vacuum gage it is possible to receive idea of a condition of piston group, of tightness of laying of a head of the block of the cylinders which are soaking up and final collectors, correctness of adjustments of a power supply system of the engine and production of exhaust gases, capacity of exhaust gases, a condition of valves (their zalipaniye or a burn-out) and springs of valves and also to check correctness of adjustment of the moment of ignition and preservation of phases of a gazoraspredeleniye at operation of the engine. Unfortunately, indications of the vacuum gage are difficult for interpreting and results of the analysis of indications can be erroneous therefore, vacuum diagnostics is expedient for uniting with other methods. Initial factors on which indications of the vacuum gage are analyzed and the most exact conclusions about an engine condition become, absolute instrument reading and nature of movement of an arrow of the device (dynamics of indications) are. A scale of the majority of vacuum gages проградуирована in mm. рт. column. In process of depression increase (and respectively pressure drop) instrument reading increases. Attach the vacuum gage directly to a soaking-up collector, but not to other openings through which the vacuum, by the channel of a certain length separated from a collector (for example, to openings before a butterfly valve) is created. Before the beginning of tests completely warm up the engine. Block wheels and put the car on the hand brake. At position of the lever of gear shifting in neutral situation (or in the situation Park on cars with automatic transmission) start the engine and leave to idle. Prevention Check the vacuum gage indication. On the serviceable engine the vacuum gage should show depression of 430-560 mm Hg, and the arrow of the device should be almost motionless. The description of character of indications of the vacuum gage and technique of definition of a condition of the engine on their basis
