3.3.27.5. Be healthy a diesel engine

The motor has sneezed time, another and has calmed down... Everyone who got to such situation, for certain knows, what plenty of questions is carried by in a head during unsuccessful attempts again to start "heart" "an iron horse". Owners of cars with diesel engines differ nothing from all other, however the reasons of troubles with diesel engines and ways of their elimination are in many respects specific to this type of motors. Not to complicate to itself a life, it is better to listen to councils of the professionals having solid practice in this area.

To them have addressed and this time, having gathered weight of the helpful information and enough a simple practical advice in realisation.

The greatest surprise appears that else yesterday the engine not delivering efforts suddenly at all refuses to "revive" while you hasten for work in the morning. If the such has happened for the first time, moreover is accompanied by a white exhaust almost with full confidence it is possible to tell that вивноваты candles накаливания. By the way, the indicator on the panel of devices quite can and be mistaken, asserting that with candles all "о'кей". For check one end of a wire is brought to accumulator "plus", and the second submits pressure directly on candles. If the good spark (it easy to distinguish from bright flash of short circuit) thus slips, the wire начинанет to be heated, and after that the motor is got, candles here at anything. It is necessary to search for a malfunction in the electric chains submitting on them pressure. Thus it is possible to check up also the valve of giving of fuel.

And, at last, blame only itself if tried to get before the car straight off. The belt газораспределительного the mechanism thus without ceremony could slip through some teeths. To start the motor it is not possible and, probably, it is necessary to prepare for difficult and expensive repair of the engine.

As shows experiment, other situation is very widespread also – the engine idles, and at attempt to add turns at once глохнет or stops, hardly having worked. Most likely, air has got to fuel system. It is necessary to pay attention to an exhaust besides. In this case it, as a rule, white with a characteristic smell of solar oil. Depression in a fuel stream can arise because of засора, say, топливозаборника or the fuel filter. More often the fuel filter is hammered, and such troubles arise mostly during winter time.

Experts of firm "աѽ" advise to all to adhere to a rule which do not have exceptions: never to repair fuel filters. Various "washings", "blowings off", and other, ostensibly restoring procedures, at the best simply will not give effect, and in the worst – still will aggravate position. Fuel, passing through such "restored" filter, not only does not receive the put clearing, but also washes off from the filter all dirt which has collected in it before. It quickly enough can put out of action precision mechanism TNVD.

One more pseudo-help to the motor which "knowing" mechanics like to render, – installation of several fuel filters. From the point of view of achievement of unknown cleanliness of solar oil of sense arriving in the engine in this multistage filtration is not present. Firms-manufacturers of diesel cars carry out exact calculations of productivity of filters which prove to be true the whole series of tests, therefore he should be trusted. Additional filters are not simply useless, and are harmful. They create excessive resistance owing to what ТНВД works with перегрузокй and faster fails. The increased resistance in the pipeline can become also the reason подсасывания air.

It is not necessary to follow the tastes and one more enough popular belief that additional filters promote branches of water from fuel. Actually filters do not detain water, for this purpose there are special sediment bowls-separators. The small stopper testifies to presence of such separator from below under the filter. To merge collected moisture follows approximately through each 3000 km of run. To merge a liquid it is necessary until almost pure solar oil will begin to flow.

Water presence in fuel also causes white clouds of exhaust gases. Some modern diesel cars have the indicator on the panel of devices which will inform that in fuel there is a water. If the indicator has lighted up, better, without postponing on then, to stop, muffle the motor and to merge a liquid from a separator. If necessary it is possible to repeat procedure. If and after that индиктор does not wish to die away, that, possibly, a problem in electric chains of system of indication of presence of water in fuel. To try to correct something in a bottom quickly it is not necessary, it is better обраться in car-care centre.

Happens also such that gradually hooting engine suddenly unexpectedly becomes silent. Most тривильный council which as it is strange, helps with many "heavy" cases – be convinced that in a tank still there is a solar oil. If business is worse, and really something has occurred, it is necessary to remember, whether was any sharp sound before the engine has broken off. Such sound accompanies belt breakage газораспределительного the mechanism. If so it is better not to try to scroll the motor – consequences can be destructive.

All the same air in fuel system can become other reason of a sudden stop of the motor. It is possible to try to connect directly the fuel pump to any capacity with solar oil. If the engine starts to work, the reason is found. At any problems with the fuel pump is better to address to experts, without trusting repair to doubtful mechanics.

When ТНВД it is excluded from probable originators of troubles, it is possible to try to weaken unions on atomizers. If during attempts to start the engine from under them solar oil starts to follow a pulsing stream, it means that faulty atomizers do not provide normal receipt of fuel in combustion chambers. Probably, you will notice that has tumbled down a black smoke of an exhaust is one of signs of lag of a needle in an atomizer. Fuel starts неконтролируемо to arrive in the cylinder, and the black exhaust is caused by its incomplete combustion.


The prevention

And one more – it is not necessary to go is dashing through deep pools. To masters it is necessary to see frequent the motors of diesel cars to crippled after such bathing. Water from a pool gets to the combustion chamber, and the strongest hydrodynamic blow bends even the strongest rods!
