15.2. Recommendations about engine start-up in a strong frost
The main problem in the winter — start-up of the cold engine. Is more often it arises with reference to carburettor motors, but in a strong frost it can face and the owner of the car with инжекторным the engine. The reasons are known: the thickened oil, falling of capacity of the storage battery and bad evaporation of gasoline.
One of variants of the decision of this problem — installation of electric devices of heating of a liquid of system of cooling of the engine (prestarting heaters).
The basic lack of electroheating of a cooling liquid consists that at the house or office it is necessary to have a special guard with the socket. The exit — an independent heater on liquid fuel which too is built in system of cooling of the engine and works by a principle of a water-heating copper. As fuel for it gasoline or diesel fuel depending on on what the engine of your car works serves.
The advantage of heating systems consists also that at their application the engine resource increases. Each start-up of the cold motor at temperature–20 °С is equivalent to run of 800 km. By the way, according to modern views, the motor will reach working temperature faster, and its deterioration will be less if after start-up not to be at a stop, and to begin movement as soon as possible, avoiding, of course, excessive loading on the engine.
Installation of heaters of system of cooling of the engine should be spent only at firm servicing deports.
Procedure of start-up of the engine without a prestarting heater in strong frosts practically does not differ from the habitual. It is possible to recommend only to perform the following preparatory operations facilitating start-up of the cold engine.
1. If the car stood more than one night, after ignition inclusion before start-up of the engine wait 3–5 with that the electrogasoline pump has had time to raise pressure of gasoline in the power supply system to the worker.
2. The capacity of the storage battery on a strong frost decreases, and power inputs on проворачивание with the thickened oil it is much more cranked shaft of the engine. To increase service life of the storage battery, before starter inclusion include on 30-60 about a headlight of headlights, using подрулевой the switch in a mode of the light alarm system. Because of passage of a small current to the storage battery chemical processes and its ability to give energy essentially begin increases.
3. If the engine was not started up from the first attempt (the starter worked 5–10), the second can be undertaken not earlier than through 30 with. If the engine was not got from the third attempt, it is necessary to search for malfunctions in power supply systems and ignitions.
Do not try to start up in a strong frost the engine towage. At such start-up often happens перескакивание a gear belt of a drive газораспределительного the mechanism, expensive repair of the engine as a result is required.
