126.96.36.199. Be healthy the diesel
The motor sneezed time, another also calmed down... Everyone who got into such situation for certain knows what swarm of questions rushes in the head during unsuccessful attempts again to start "heart" of "an iron horse". Owners of cars with diesel engines differ in 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 like motors. Not to complicate to itself life, it is better to follow advices of the professionals having solid practice in this area.
Addressed them and this time, having gathered the mass of useful information and pretty simple practical advice in realization.
The biggest surprise turns out the fact that still yesterday the engine which was not bringing trouble suddenly at all refuses "to come to life" while you hurry for work in the morning. If it happened for the first time moreover is followed by a white exhaust, then almost with full confidence it is possible to tell that glow plug vivnovata. By the way, the indicator on the dashboard can quite be mistaken, claiming that with candles all "OK". For check one end of a wire is brought to accumulator "plus", and the second gives tension directly on candles. If at the same time the good spark (it easy to distinguish from bright flash of short circuit) slips, the wire nachinant to be heated, and after that the motor is started, then candles here at anything. The malfunction should be looked for in the electric chains giving on them tension. Thus it is possible to check also the fuel supply valve.
And, at last, you blame only yourself if tried to start the car straight off before. The belt of the gas-distributing mechanism at the same time easily could slip through several teeths. It is not possible to start the motor and, perhaps, it is necessary to prepare for complex and expensive repair of the engine.
As shows experience, also other situation is very widespread – the engine idles, and in attempt to add turns becomes deaf at once or stops, having slightly worked. Most likely, air got to fuel system. It is worth paying 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 blockage, say, of a toplivozabornik or the fuel filter. Fuel filter is most often hammered, and such troubles arise mostly in winter time.
Specialists of Tekhnodiesel advise all to follow the rule which does not have exceptions: never to repair fuel filters. Various "washings", "blowings off", and the other, allegedly restoring procedures, at best just 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 all dirt which collected in it before from the filter. It quickly enough can put the TNVD precision mechanism out of action.
One more pseudo-help to the motor which the "knowing" mechanics like to render, – installation of several fuel filters. From the point of view of achievement of unprecedented purity of the sense diesel fuel coming to the engine in this multistage filtration is not present. Firms manufacturers of diesel cars carry out exact calculations of productivity of filters which are confirmed by the whole series of tests therefore they should be trusted. Additional filters are not simply useless, and are harmful. They create excessive resistance owing to what TNVD works with перегрузокй quicker fails. The increased resistance in the pipeline can become the air podsasyvaniye reason also.
You should not follow the tastes and one more rather popular belief that additional filters promote offices of water from fuel. Actually filters water do not detain, for this purpose there are special settlers separators. Existence of such separator is demonstrated by a small stopper from below under the filter. It is necessary to merge the collected moisture approximately through each 3000 km of a run. It is necessary to merge liquid until almost pure diesel fuel begins 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 water. If the indicator lit up, better, without putting away for later, to stop, kill the engine and to merge liquid from a separator. If necessary it is possible to repeat the procedure. If after that the indiktor does not want to die away, then probably a problem in electric chains of system of indication of availability of water in fuel. To try to correct something in a quick bottom is not necessary, it is better to obratsya in car service.
There is also it that gradually the 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 worth remembering whether it was some sharp sound before the engine broke off. The break of a belt of the gas-distributing mechanism is followed by such sound. If so, then 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 the fuel pump to any container with diesel fuel directly. If the engine begins to work, then the reason is found. At any problems with the fuel pump it is the best of all to address 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 begins to follow the pulsing stream, it means that faulty nozzles do not provide normal intake of fuel in combustion chambers. Perhaps, you will notice that black smoke of an exhaust tumbled down - it is one of signs of lag of a needle in a nozzle. Fuel begins to come uncontrollable to 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!
