GENERAL INFORMATION

The main problem in the winter – launch of the cold engine. More often it arises at carburetor motors, but in a hard frost it also the owner of the car can face the injector engine. The reasons are known – the thickened oil, falling of capacity of the accumulator and bad evaporation of gasoline. We will consider oils and accumulators separately for now – several words about experience of the countries with a frigid climate where prestarting electric heaters – such "kipyatilnichka" in the engine cooling system are widely applied. Drove up to the house or to office, thrust a fork in the socket, turned on the timer... By the necessary time the engine will be heated-up, and some designs provide also warming up of salon.

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

The main lack of electroheating consists that at the house or office it is necessary to have a special guard with the socket. It to Finns is good, and we have the corresponding infrastructure if appears, then not soon and not everywhere. Other exit – an autonomous heater and uses liquid fuel which is built in the cooling system of the engine too by the principle of the boiler. As fuel for it serves gasoline or diesel fuel, depending on what the engine of your car works at.

Autonomous heaters of production Eberspacher, Webasto, and also product of the Shchadrinsky automodular plant (ShchAAZ) are presented at the Russian market.

It is possible to establish a heater at specialized stations which there is already a lot of also in Moscow, and in general across Russia. Warming up time – no more than 15 minutes, at the same time is spent by only 200 g of gasoline or diesel fuel. Such heaters (besides the timer) can be completed with the device of remote control. The cost of an autonomous heater in the Russian market – about $1000.

The advantage of systems of heating consists also that at their application the engine resource increases. For reference: each launch of the cold motor at a temperature of -20 °C is equivalent to a run in 800 km. By the way, according to modern views the motor will reach working temperature quicker, and its wear will be less if after start-up to do not stand still, and to begin the movement as soon as possible, avoiding, of course, excessive load of the engine.
