3.3.27.3. Care of a diesel engine

As the diesel engine pollutes oil in lubricant system faster, than the petrol engine, the majority of manufacturers of cars provide more frequent change of oil and the filter.

Special oils of diesel engines are widely accessible today and, judging by responses, are effective enough. However any high-quality engine oil for carburettor engines also will approach and for a diesel engine if only it to change through certain intervals. Read a label on bank in which the manufacturer usually instructs concerning diesel engines. If on this label will find nothing, look a label on the container in which banks have been packed.

At engines with the top cam-shaft it is necessary to replace a gear belt through the specified intervals. Otherwise impact of the piston with valves when the belt will suddenly tear is not excluded. Elimination of consequences of the last will demand from you considerable financial expenses. In practice already there were cases of breakage of belts with run to 48 thousand in km, but there was it as a result of hit on them oils or waters because of depressurization accordingly greasing and cooling systems. However, if you take in head to go, without changing a belt, after run of 58 thousand in km your unwillingness waste time on timely replacement of a belt can to turn back for you further considerably the big expenses of time and money.

For replacement of the fuel filter buy best of accessible to you. Some filters can look outwardly good, but "it is bad to fulfil the direct duties". Do not forget to replace also a sealing ring on the filter case. Still we will notice that on a diesel engine it is equally difficult to prevent as fuel leak, and подсос air in fuel system which strongly break engine work.

If air gets in топливопроводы its removal therefrom through the special valve by means of the small manual pump usually mounted for these purposes on the fuel pump of a high pressure can be demanded. Many modern diesel engines have the power supply systems self-deleting air. It is necessary only крутануть the engine a starter, and air will leave.

It is difficult to avoid that in the fuel filter the moisture was not condensed, therefore for some diesel engines on the panel of devices the alarm lamp informing on presence of water in fuel system is provided.

Usually at oil replacement it is required to check up a filter condition only. However in case of car operation under trying conditions, such as the raised humidity and the big differences between day and night temperatures to check a condition of filters follows a thicket.

All diesel engines on a cold smoke, but it should not be excessive. One of the most widespread reasons of it is failure at the moment of giving of fuel by the pump of a high pressure which is easily eliminated by repeated adjustment of the moment of injection on labels on a cranked shaft and the pump. The given work very much reminds adjustment of an initial corner of an advancing of ignition on the petrol engine. Operation can be made on the idle engine, however is better get for these purposes a special lamp for installation of the moment of injection on a diesel engine which fastens a clip on топливоподводящей to a tube of an atomizer and flashes under the influence of pushes of the fuel which is passing on a tube.

Other reason is подтекание fuel through atomizers with leaky closed топливоподающим the channel that can lead to overflow of the cylinder by fuel and, as consequence, to excessive дымлению at start-up. Except the general clearing of atomizers and replacement worn out at run about 110 thousand in km, a little that it is possible to make in house conditions to check up their work. Unless to remove them and to give to check up on any control equipment.

New atomizers are not cheap, but you can save the considerable sum, having addressed on the station which is engaged in repair of diesel engines, and to calibrate atomizers under quite comprehensible price. The price for service depends on an arrangement of station and presence round it shops of spare parts.

However you in a condition to prolong service life of atomizers, supporting in cleanliness air soaked up by a diesel engine and fuel filters and by that to counteract pollution of atomizers. For these purposes it is necessary to fill in periodically in a fuel tank in a small amount special cleaners.

If to watch the fuel pump of a high pressure it will be long and to function regularly. However we wish to warn that its replacement – expensive enough invention.

Bad start-up and low приемистость a diesel engine can be caused many things: substandard starting candles, a contamination of channels of the fuel highways, leading to pressure drop of giving of fuel, malfunction топливопроводов and even wrong installation of atomizers. To define badly working starting candles easily how the control bulb of prestarting warming up long does not die away.

Talk to owners of diesel cars, and you will see that anybody from them and does not wish to think of again to sit down for a wheel of the petrol car. Probably, there has come also your turn if the diesel engine quite answers your inquiries.
