The motor sneezed time, another and calmed down... Everyone who got to such situation, for certain knows, what swarm of questions is carried by in the 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 for this purpose such as motors. Not to complicate to itself life, it is better to listen to councils of the professionals having solid practice in this area.

To them addressed and this time, having gathered mass of useful information and pretty simple in realization of a practical advice.

The biggest surprise appears that still yesterday the engine not delivering efforts suddenly at all refuses to "revive" while you hurry for work in the morning. If the such happened for the first time moreover is accompanied by a white exhaust, almost with full confidence it is possible to tell that glow plugs are guilty. By the way, the indicator on the dashboard quite can and be mistaken, arguing that with candles all o'ky. For check one end of a wire is brought to accumulator "plus", and the second submits tension directly on candles. If the good spark thus slips (it easy to distinguish from bright flash of short circuit), the wire starts to be heated, and after that the motor is got, candles here at anything. The malfunction should be looked for in the electric chains submitting on them tension. Thus it is possible to check also the valve of supply of fuel.

And, at last, blame only itself if tried to get before the car straight off. The belt of the gas-distributing mechanism thus easily 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 the experiment, other situation is very widespread also – the engine idles, and in attempt to add turns at once глохнет or stops, having slightly worked. Most likely, air 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 diesel fuel. Depression in a stream of fuel can arise because of a zasor, say, a toplivozabornik or the fuel filter. More often fuel filter is hammered, and such troubles arise mostly during winter time.

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

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 purity of diesel fuel 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 trust. Additional filters are not simply useless, and are harmful. They create excessive resistance owing to what TNVD works with перегрузокй and quicker fails. The increased resistance in the pipeline can become the reason of a podsasyvaniye of air also.

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

Availability of water in fuel also causes white clouds of exhaust gases. Some modern diesel cars have the indicator on the dashboard which will report that in fuel there is a water. If the indicator lit up, better, without postponing for later, to stop, muffle the motor and to merge liquid from a separator. If necessary it is possible to repeat procedure. If after that the indicator does not want to die away, that, possibly, a problem in electric chains of system of indication of availability of water in fuel. To try to correct something in them quickly it is not necessary, it is better обраться in car-care center.

It happens also such that gradually hooting engine suddenly unexpectedly becomes silent. The most trivilny council which as it is strange, helps with many "heavy" cases – be convinced that in a tank still there is a diesel fuel. If business is worse, and really something occurred, it is necessary to remember, whether was any sharp sound before the engine broke off. Such sound accompanies break of a belt of the gas-distributing mechanism. If so, it is better not to try to scroll the motor – consequences can be destructive.

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 diesel fuel. If the engine starts to work, the reason is found. At any problems with the fuel pump it is best of all to address to experts, without trusting repair to doubtful mechanics.

When TNVD is excluded from probable responsible for troubles, it is possible to try to weaken unions on nozzles. If during attempts to start the engine from under them diesel fuel starts to follow a pulsing stream, it means that faulty nozzles do not provide normal intake of fuel in combustion chambers. Probably, you will notice that tumbled down a black smoke of an exhaust is one of signs of lag of a needle in a nozzle. Fuel starts to arrive uncontrollable in the cylinder, and the black exhaust is caused by its incomplete combustion.


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