1.17.2. Engine


The main problem in the winter – start-up of the cold engine. More often it arises at carburetor motors, but in a hard frost with it can face and the owner of the car 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 – some words about experience of the countries with a frigid climate where prestarting electroheaters – such "kipyatilnichka" in system of cooling of the engine are widely applied. Approached on 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 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 heater of a domestic production (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 is to Finns well, and at us the corresponding infrastructure if will appear, not soon and not everywhere. Other exit – an independent heater and works at liquid fuel which too is built in system of cooling of the engine by a principle of a water-heating copper. As fuel for it gasoline or diesel fuel, depending on at what the engine of your car works serves.

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

To establish a heater it is possible at specialized stations which there 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 g of gasoline or diesel fuel. Such heaters (besides the timer) can be completed with the device of remote control. Cost of an independent heater in the Russian market – about $1000.

The advantage of systems of heating consists also that at their application the engine resource increases. For the reference: each start-up of the cold motor at temperature–20 ° to C is equivalent to 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 not to be at a stop, and to begin movement as soon as possible, avoiding, of course, excessive load of the engine.
