Care diesel

Since diesel pollutes the oil in the lubricating system faster than a gasoline engine, the majority of car manufacturers provide for more frequent oil and filter change.

Special oils diesels widely available today, and judging by the reviews, is quite effective. However, any high quality motor oil for gasoline engines and is also suitable for diesel, if only to change it at regular intervals. Read the label on the bank, in which the manufacturer usually provides guidance for the diesels. If this label will not find anything, you look at the label on the container in which the banks were packed.

In engines with overhead camshaft timing belt should be replaced at specified intervals. Otherwise, it is possible collision with the piston valves when the belt suddenly broken. Eliminating the effects of the latter will require you considerable financial costs. In practice, there were cases already broken belt with mileage up to 48 thousand. Km, but it is happening as a result of contamination from oil or water due to depressurization, respectively, lubricating and cooling systems. However, if you decided to drive without changing the belt after a run of 58 thousand. Km, is your reluctance to spend time on the timely replacement of the belt may turn out to you in the future much greater expenditure of time and money.

To replace the fuel filter buy the best available to you. Some filters may look superficially good, but "bad fulfill their direct duties." Do not forget to replace the O-ring on the filter housing. Another note that the diesel is equally difficult to prevent leakage of both fuel and air leak in the fuel system, which strongly violates the engine.

If air gets into the fuel lines, you may need to remove it from there through a special valve with a small hand pump, usually mounted for this purpose on the high pressure fuel pump. Many modern diesel engines have a power supply system, air deletes itself. We just need to spin the starter motor and the air is removed.

It's hard to avoid that the fuel filter is not condensed moisture, so some diesel engines on the instrument panel provides indicator light, announcing the presence of water in the fuel system.

Typically, when an oil change is only required to check the condition of the filter. However, in the case of use of the vehicle in difficult conditions such as high humidity and big differences between day and night temperatures, check the condition of the filter should be more often.

All diesel engines in the cold smoke, but it should not be excessive. One of the most common reasons for this is a failure at the time of the high-pressure fuel pump, which can be easily eliminated by re-adjusting injection timing marks on the crankshaft and the pump. This work is very similar to the initial adjustment of the ignition timing on the gasoline engine. The operation can be done on the engine is not running, but it is better to buy for this purpose a special lamp for the installation of the moment of injection of diesel, which is attached to the clamp toplivopodvodyaschey tube nozzle and breaks under the shock of fuel passing through the tube.

Another cause is leakage of fuel through the nozzle tightly closable with a fuel supply channel, which may result in an overflow cylinder with fuel and, consequently, excessive smoke during starting. Apart from general cleaning the nozzles and replace worn at run about 110 thousand. Km, little can be done even at home to check their work. Does that take them and give to check up on any control equipment.

The new jets are not cheap, but you can save a considerable amount, referring to the station, is engaged in repair of diesel engines, and to calibrate the nozzle at an affordable price. The price of the service depends on the location of stations and the availability of spare parts around the shops.

However, you are able to extend the service life of nozzles in keeping clean the intake air and diesel fuel filters and thereby counteract contamination nozzles. For these purposes should be periodically poured into the fuel tank in a small amount of special cleaners.

If you follow the high pressure fuel pump, it will be long and to function properly. However, we want to warn you that his replacement - a rather expensive undertaking.

A bad start and a low pick-diesel can be caused by many things: substandard launchers candles, clogging canals fuel lines leading to a drop in fuel pressure, and even malfunction of the fuel nozzles improper installation. Identify poorly performing candle launchers easily by how long the control lamp does not go out plugs warming.

Talk to owners of diesel cars, and you will see that none of them does not want to think about how to re-take the wheel petrol car. Perhaps it is your turn, and if the diesel fully meets your needs.
