1.17.2. The engine

The main problem in the winter – start-up of the cold engine. Is more often it arises at 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 accumulator and bad evaporation of gasoline. And accumulators we will consider oils separately, for now – some words about experience of the countries with a frigid climate where prestarting electroheaters – such "кипятильнички" in system of cooling of the engine are widely applied. Has approached on the house or to office, has thrust a plug in the socket, has included the timer... By the necessary time the engine will be heated-up, and some designs provide also salon warming up.

Electric devices of heating are presented some years and in the Russian market. The Finnish heaters which can be completed with timers use the greatest popularity. Cost together with installation – about $250. Approximately for $100 it is possible to get a domestic production heater (for VAZOVSKY models and "Volga"), but the timer for it is not provided.

The basic lack of electroheating consists that at the house or office it is necessary to have a special guard with the socket. It is to Finns well, and at us the corresponding infrastructure if will appear, not soon and not everywhere. Other 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 solar oil, depending on on what the engine of your car works serves.

In the Russian market independent heaters of manufacture Eberspacher, Webasto, and also products of Shchadrinsky automodular factory (ЩААЗ) are presented.

To establish a heater it is possible at specialised stations which it is already a lot of and in Moscow, and as a whole across Russia. Warming up time – no more than 15 minutes, is thus spent only 200 г gasoline or дизтоплива. Such heaters (besides the timer) can be completed with the remote control device. Cost of an independent heater in the Russian market – about $1000.

The advantage of heating systems consists also that at their application the engine resource increases. For the inquiry: each start-up of the cold motor at temperature–20 C is equivalent to run in 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.
