The cars considered in the real Management, are equipped with two types of systems of ignition – system with the external electronic block and system with the internal block of ignition. The last differ that the electronic block ignitions (switchboard) is built in the case of the distributor of ignition. On both systems the coil of ignition is mounted in the distributor.
Into system of electronic ignition enter:
– ignition lock;
– block of electronic ignition;
– induction sensor;
– ignition coil;
– wires of a low-voltage (primary) chain and high-voltage (secondary) chain;
– ignition and spark plug distributor.
Work of system of ignition the electronic processor block (ESM-blok) operates. ESM-blok provides automatic adjustment of a corner of an advancing of ignition according to signals from sensors which trace various parameters of the engine (such as number of turns, volume of sucked-in air, temperature of cooling liquid, etc.). Such system is called as ignition system with electronic control by the moment of ignition (ESA system).
Contactless systems of ignition are subdivided into two groups – systems with the built-in electronic block of ignition and system with the external electronic block (see fig. Details of contactless system of ignition with the external electronic block and fig. Details of contactless system of ignition with the built-in electronic block). Before replacement of any detail of system of ignition be convinced that all checks are executed in full volume and what exactly this detail it is necessary to replace. It is connected with high cost of details, and also that they as a rule are not subject to return.
At performance of checks and repair of system of ignition it is necessary to observe the following safety rules:
– at refusal of start-up of the engine do not leave ignition included for a while bigger 10 minutes;
– connect a tachometer according to the instruction of the manufacturer (before acquisition of a tachometer consult in service of car-care center of the dealer);
– do not allow a contact of conclusions of the coil of ignition with weight (failure of the block of electronic ignition and the coil otherwise is possible);
– it is forbidden to disconnect the battery from weight on the working engine;
– constantly watch that the block of electronic ignition was reliably connected to weight.
The system of ignition develops very high voltage therefore, at works it is necessary to observe extra care. Potential danger represent not only the block of electronic ignition, the coil, the distributor and high-voltage wires, but also such auxiliary details as tips of high-voltage wires, a tachometer, and other instrumentations.
| PERFORMANCE ORDER
| 1. If the engine is not started, and the starter vigorously turns the crankshaft, disconnect high-voltage wires from candles and connect to them the calibrated rated sportsman for ignition check (is available on sale). Connect one of rated sportsman conclusions to a bolt or a metal arm on the engine. In the absence of a test rated sportsman disconnect a wire from one of candles, take away isolating tip and fix a wire the isolated tool at distance about 6,0 mm from the bared site of weight.
| 2. Turn the crankshaft a starter and watch a rated sportsman or a candle wire. There should be an intensive spark of blue color.
| 3. If the spark is available, on candles necessary tension moves (check other wires to be convinced of serviceability of a cover of the distributor and a begunka). Turn out candles and check them (see subsection 2.8.2).
|4. If the spark is absent, or an iskroobrazovaniye unstable, uncover the distributor and check a condition of a cover and a begunka (subsection 2.8.3). At detection of moisture wipe dry a cover and a begunok, establish a cover on a place and repeat check.
|5. If sparks on former are not present, disconnect from a distributor cover a high-voltage wire of the coil of ignition and connect a wire to a test rated sportsman (a wire of a candle establish into place). Repeat tests. In the absence of a rated sportsman fix a coil wire the isolated tool at distance about 6,0 mm from the bared site of weight.
||6. If the spark appeared, malfunction of a cover of the distributor or a begunka can be the reason.
||7. In the absence of a spark check all conducting of primary chain of the coil of ignition, be convinced of purity and reliability of connections. Whether check tension on the coil from the ignition key arrives. Check the ignition coil (see subsection 3.3.5) and the induction sensor of the distributor (see subsection 3.3.9). Execute necessary repair and repeat test.
|8. If the spark on the former is absent, replace a wire connecting the coil of ignition and a distributor cover (check resistance of a wire and compare to the standard value specified in subsection 2.1). If replacement of a wire by the obviously serviceable does not give result, the electronic block of ignition is faulty.
||9 whether. Check tension from the battery on the electronic block moves at ignition inclusion. If tension is absent, replace the electronic block (see subsection 3.3.8).
