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 used car, with the carburetor motor – then another matter. Actually, power supply systems and ignitions are among themselves not connected. But on modern engines with injection you will not meet either the memorable mechanical distributor, or contacts of the breaker. And on carburetor – as much as necessary. And not to potter then on a frost, it is necessary to clean contacts, 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 few years of driving on our "salty" roads it is desirable to change them, and better – on wires with a silicone cover which are less sensitive to differences of temperatures. Besides, on them hoarfrost which often is the reason of lack of a spark is not formed. By the way, corrosion or a bad inhaling of accumulator plugs can be the banal cause of malfunctions of ignition.

Separately – about candles. Usually they are changed through 15–20 thousand kilometers, i.e. time in one and a half years (we do not take the 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 is inexpensive. Also put new in anticipation of winter. Fuel system

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

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

To owners of diesel foreign cars, especially if the car was operated in the country with soft climate earlier, it is worth taking care of equipment of fuel system special devices of heating. Practice shows that to start the diesel motor at –20 °C can be difficult as fuel loses fluidity (how "winter" diesel fuel which at us is on sale in the winter is – it is only possible to guess). One of effective measures – application of the warmed-up toplivoprivod and filters. At the same time it is possible to launch the diesel motor even at –40 °C. Heating is carried out by elements which eat from the regular accumulator.

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