As the diesel engine pollutes oil in lubricant system quicker, than the petrol engine, the majority of producers of cars provide more frequent change of oil and the filter.
Special oils of diesel engines are widely available today and, judging by responses, are quite effective. However any high-quality engine oil for carburetor engines also will be suitable 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 at a label on the container in which banks were packed.
At engines with the top cam-shaft it is necessary to replace a gear belt through the specified intervals. Otherwise piston impact 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 break of belts with run to 48 thousand km, but there was it as a result of hit on them of oil or water because of depressurization respectively greasing and cooling systems. However, if you take in head to go, without changing a belt, after run of 58 thousand km, your unwillingness waste time on timely replacement of a belt can to turn back for you further considerably big expenses of time and money.
For replacement of the fuel filter buy best of available to you. Some filters can look outwardly well, but "it is bad to fulfill the direct duties". Do not forget to replace also a sealing ring on the filter case. Still we will note that on a diesel engine it is equally difficult to prevent as leakage of fuel, and подсос air in fuel system which strongly break operation of the engine.
If air gets in топливопроводы, removal can be demanded it from there via the special valve by means of the small manual pump which is usually mounted for these purposes on the fuel pump of a high pressure. Many modern diesel engines have the power supply systems self-deleting with air. It is necessary only крутануть the engine a starter, and air will be removed.
It is difficult to avoid that in the fuel filter moisture therefore for some diesel engines on the dashboard the alarm lamp informing on availability of water in fuel system is provided was not condensed.
Usually at replacement of oil it is required to check a filter condition only. However in case of car operation under trying conditions, such as the increased humidity and big differences between day and night temperatures to check a condition of filters follows a thicket.
All diesel engines on cold smoke, but it should not be excessive. One of the most widespread reasons of it is failure in the moment of supply of fuel the pump of a high pressure which is easily eliminated with a way of repeated adjustment of the moment of injection on labels on a cranked shaft and the pump. This 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 it is better to get for these purposes a special lamp for installation of the moment of injection on diesel engines which fastens a clip on a toplivopodvodyashchy tube of a nozzle and flashes under the influence of pushes of the fuel passing on a tube.
Other reason is podtekany fuels through nozzles with leaky closed toplivopodayushchy channel that can lead to cylinder overflow by fuel and, as a result, to an excessive dymleniye at start-up. Except the general cleaning of nozzles and replacement about 110 thousand km worn out at run, a little that it is possible to make in house conditions to check their work. Unless to remove them and to give to check on any control equipment.
New nozzles 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 nozzles at quite acceptable price. The price for service depends on an arrangement of station and existence of shops of spare parts round it.
However you in a condition to prolong service life of nozzles, keeping clean air soaked up by a diesel engine and fuel filters and by that to counteract pollution of nozzles. 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 want to warn that its replacement – quite expensive invention.
Bad start-up and low acceleration performance of a diesel engine can be caused by many things: substandard starting candles, a contamination of channels of the fuel highways, bringing to pressure drop of supply of fuel, malfunction топливопроводов and even the wrong installation of nozzles. To determine badly working starting candles easy by how the control bulb of prestarting warming up long does not die away.
The table of possible defects provided in subsection 126.96.36.199 on a diesel engine is made by Bosch firm, and we hope that it will help you to return your engine to a working order.
Talk to owners of diesel cars, and you will see that anybody from them and does not want to think of again to sit down at a wheel of the petrol car. Probably, there came also your turn if the diesel engine quite answers your inquiries.
