1.17.5. Ignition system

GENERAL INFORMATION

If you have a new car of foreign production moreover with the injector engine, it is possible not to read further. But if the car second-hand, with the carburetor motor – then business another. Actually, power supply systems and ignitions among themselves are not connected. But on modern engines with injection you will not meet neither the memorable mechanical distributor, nor breaker contacts. And on the carburetor – as much as necessary. And not to potter then on a frost, contacts should be cleaned, a distributor cover – too (and it is better to replace). Even better – to replace classical system of ignition on electronic (if still there were car owners who did not make it).

Do not forget about high-voltage wires. After driving few years on our "salty" roads they are desirable for changing, and it is better – on wires with a silicone cover which are less sensitive to differences of temperatures. Besides, on them hoarfrost which often is at the bottom of lack of a spark is not formed. By the way, corrosion or a bad inhaling of storage plugs can be the banal reason of malfunctions of ignition.

Separately – about candles. Usually them change through 15–20 thousand kilometers, i.e. time in one and a half years (we do not take supermodern, maintaining 100 thousand km and more). It is not necessary to save on candles – to calcinate, clean and regulate gaps. Change at least once a year it it is inexpensive. Also put new on the threshold of winter. Fuel system

Quite often it is at the bottom of unsatisfactory operation of the engine during winter time. And all – because of the water condensate which has accumulated in a fuel tank. If in a tank there is a drain stopper, water can be merged simply if is not present – to "neutralize", having applied so-called "vytesnitel of moisture". Practically all leading producers of auto chemical goods who are present in the Russian market (STP, Loctite, WynnХs, Aspokem), offer similar preparations which are filled in in a fuel tank and gradually clear a power supply system.

To the superfluous will not deliver the new filter of thin purification of fuel, to clean the carburetor and if the motor has injection system – to be convinced of purity of injectors.

To owners of diesel foreign cars, especially if the car was maintained earlier in the country with soft climate, it is necessary to take care of equipment of fuel system by special devices of heating. Practice shows what to get the diesel motor at–20 ° With happens difficult as fuel loses fluidity (how "winter" diesel fuel which at us is on sale in the winter is – it is possible to guess only). One of effective measures – application warmed up топливоприводов and filters. Thus to start up the diesel motor it is possible even at–40 ° for S.Podogrev it is carried out by elements which eat from the regular accumulator.

The current consumed by them makes near 5А, inclusion of heaters for 5–10 minutes practically does not affect accumulator capacity.
