CAR DIAGNOSTICS
The posts of technical diagnostics Diagnosis — the process of establishing a technical- state of units, assemblies, systems and mechanisms related to car Biel with the help of devices and devices without their noticing- CI. It gives the opportunity to detect faults, for the mouth- wounds which require adjustment or repair nye's work. At the time of the diagnosis are divided into non- discontinuous and periodic. Continuous diagnostics is the driver in the operation of automotive La. Periodic diagnosis is performed through the determi- divided, pre-set mileage. In accordance with the system of scheduled preventive repair and maintenance diagnostics de will into two types: General D-1 atomic and D-2. When the diag- the investment d-1, determine the technical condition of knots and units which ensure the safety of road movement, and evaluate the suitability of the car for operation orientation. Done it before-1. When the diagnosis item D-2 not detected- health, set the volume adjustment and maintenance the Internet works during the MOT-2 predict resource is- legal work until the next service. Depending on the volume of work on THE TP and the diagnosis aims is carried out on the production line, and separate posts. On the production line the main posts di- agnostics are placed in areas to-1 and to-2. Individual posts organized in sections according to the current repairs of aggregates and units of vehicle, such as repairs, the engines, repair transmissions, etc. Such an arrangement of the posts allows for diagnosis- ical measurements before and after repair, providing the first break evolution its quality, thus the opportunity auto return for re-repair or a particular node, of the unit. Posts diagnosis is equipped by stationary stand- mi, mobile stations, portable devices, equipped with the necessary measuring device properties. In some cases, are used to diagnose sensors and devices on the dashboard of a car, for example measures the oil pressure sensor, temperature sensor, etc. Diagnostic stands with Jogging drums allows allow flexibility to simulate driving conditions and loads. Stand OS- Namen brake installation and flowmeter fuel that ultimately allows to check basic features- sticks of all units and units of the automobile, to compare them with pas- tailors the data to adjust the sensors and instruments on the dashboard of the car to identify unused- equality. Posts diagnosis of the individual devices are equipped with a SPE- special instruments and devices for measuring and control the main parameters of the unit and identify them fault. So, post for diagnosing work the engine is equipped with vibroacoustic equipment, stethoscope, etc., allowing the characteristics and level Nude noises and bangs to determine the technical condition of the Cree- washino crank and gas distributing mechanisms. With a stethoscope to determine the increase of clearance in brass and main bearings of the crankshaft, between do the piston and cylinder, valves and Cam followers etc. establish the need to perform the adjustment and repair work. Mobile repair and maintenance-diagnostic workshops are designed for maintenance- with and repair of cars outside the workshop and Autotrans- tailors companies. These workshops are located in the bodywork of trucks and include equipment tion to perform the grinding of metal processing: plumbing, drilling, lathes, etc. This complex equipment allows to carry out minor repairs, including to manufacturing non-critical parts. In addition, mobile repair shop comp lectues devices, instruments, sensors for measuring operating parameters of the units and components of car and diagnostics of their technical condition. |
