The owners of the diesel car

If you're thinking about switching to diesel, but do not know how to take care of him with his hands, then immediately say that keep diesel in good condition just as easy petrol engine ...

Diesel cars are known for their durability, but that does not mean to take care of them is not required.

Prices for used diesel cars in the West fall. This is due to the fact that for a long time sales of new diesel cars was very high, and therefore the market for used cars is now a large number of them. New diesel cars are much more expensive than their equivalents in the parameters of gasoline counterparts. In addition, the time has passed when the usual for us today a number of diesel exhaust the only one model. Today, manufacturers are able to supply the market with diesel engines that meet the highest requirements.

It is regrettable the country, if any, in which diesel fuel costs equally with gasoline or even exceeds it. But even in this case, you will be the winner, because diesel cars are usually higher lifetime, but only on the condition that you will have a big annual mileage. No economy is impossible only at small annual mileage. You save on spark plugs, although it is understood that when using the spark plug replacement intervals 60 thousand. Km of savings they will be small. At the same time you lose on a more frequent replacement of oil and filter.

What attracts diesel?

Modern diesel cars are attractive for their ability to develop greater thrust at low revs than especially good for drivers who do not like to shift gears too often. Most manufacturers offer diesel engines with turbocharging to give the owner the opportunity to experience the charm of the most high-end machines.

If you're thinking about switching to diesel, but do not know how to take care of him with his hands, then immediately say that keep diesel in good condition just as easy petrol engine, despite their differences. We offer you a brief guide to buying, operating and maintenance of diesel.

Mechanisms of petrol and diesel engines are not much different. The basis of both engines put a four-cycle combustion, but it happens they have completely different ways.

While gasoline engines have fuel mixture is ignited by spark ignition, diesel fuel ignites resulting in a very high compression.

When the gasoline engine sucks air and gasoline to the first stroke, diesel sucks only air which is compressed to such an extent that its temperature rises to 800 ?� C. C. The hot air ignites the diesel fuel, which is injected into the combustion chamber of the cylinder shortly before the piston reaches BMT on the compression stroke. Since the degree of compression of diesel engines at twice higher than that of gasoline engines, the fuel injection must take place under very high pressure, so that it flew into the combustion chamber and the jet fuel retained give it form. Due to increased demands on injection, high pressure fuel pump of a diesel engine is extremely high-precision assembly manufactures.

Why diesel noise?

The familiar roar of diesel fuel ignition porazhdaet and subsequent sharp decline in the high pressure in the combustion chamber. Most clearly the specific diesel rumble is heard after starting the engine warms up during idling.

There is no diesel engine ignition system, but there is a system plugs warming up the combustion chambers of cylinders using a spark launchers. In addition, the duration of cranking the engine and anxious waiting, when the indicator lamp goes out the end plugs warming, are long gone. Already many manufacturers produce bystrozapuskayuschiesya diesel engines to run them in the winter requires no more than a couple of seconds. Some cars even have a "starter handle", which can be directly controlled high pressure fuel pump to change the point of injection, accelerate warming and reduce the emission of smoke at start-up.

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.

Buying a used engine

Be careful when buying a used diesel. Diesel engines operate for a long time, but that does not mean that you should not explore all the places traditionally wear. On some engines very easy to disguise as the duration of operation and wear. In assessing the state of the engine there is a danger "lopuhnutsya" if you are not familiar in diesel engines.

As with gasoline engines, the exhaust of a diesel engine to be smokeless. Moreover, should not emit smoke from the open mouth of the tube filler in a warm engine. Because the diesel engine has larger noise than gasoline engines, you have to distinguish between the operating noise of the rushing worn pistons, connecting rods, camshaft and so on. D. If you have doubts about the condition of the engine, then seek professional help.

Turbodiesels are very popular as turbo fits in well with the characteristics of a diesel engine. Turbochargers operate with a small boost pressure and at low engine speeds, which gives them longer than the lifetime of gasoline engines. Turbodiesels excellent for trucks and multi-ton trucks.

However, diesel automatic devices it is difficult to meet the demands of an automatic transmission for flat torque characteristics. Few manufacturers are concerned about this problem. Among them, Citroen, Mercedes, Peugeot and recently joined them Opel, but they used automatic transmissions only on the machines of the middle class.

Due to the growing popularity of all, diesel is no longer seen as the poor relation, and the level of its finish, they fully comply with their gasoline brethren.

When buying, pay attention to the residual value of the diesel engine. At the time, diesel cars boosted car sales in Germany, but the peak of sales was reached four years ago up to the present time there is a gradual decline, so make sure you do not overpay for the honor of becoming the owner of a diesel car.

Check the mileage. Diesel cars are bought because of their potentially high reliability and high mileage. Especially when they are bought new. But this does not mean that you should not pay attention to the odometer. Indeed, many traders do not like to deal with cars, the mileage of which exceeded 80 thousand. Km and, accordingly, the price is adjusted to them. Or, without further ado, just reset the mileage on the meter. Mileage 160 thousand. Km is quite natural for the well-served by a diesel engine, but think twice if the counter shows 320 thousand. Km or, especially if it is second-hand taxis with mileage.

Except for the motor, the majority of diesel cars in structure identical to their gasoline brethren, the same applies to the suspension, brakes, but consider the prices of spare parts. For example, the exhaust system are long, but different from those of gasoline engines. And if you're used to buying parts from parser damaged cars, keep in mind that the details of petrol engines may be superficially similar and suitable in size, but the engine block of a diesel engine differs from a similar block petrol engine and in most cases can not be selected as a replacement . Also, different gear ratios and clutch transmissions.

Be healthy diesel

Motor sneezed once, twice, and was still ... Everyone who got into such a situation, surely knows what goes through a swarm of questions in my head during unsuccessful attempts to re-launch the "heart" of the "iron horse." Owners of cars with diesel engines are no different from all the others, but the reasons for the trouble with diesel engines and their solutions are largely specific to this type of engines. In order not to complicate your life, it is better to see the advices of professionals with a solid practice in this area.

They appealed, and this time, pocherpnuv lot of useful information, and quite easy to implement practical advice.

The biggest surprise is the fact that yesterday did not cause trouble engine suddenly flatly refuses to "come alive" at the very moment when you morning rush to work. If this happened the first time, but still accompanied by white exhaust, almost with certainty we can say that the blame for the glow plugs. By the way, the indicator on the instrument panel may be wrong, claiming that candles all about, Kay. To check one end of the wire is fed to the "plus" the battery, and the second applies voltage directly to the candle. If the spark jumps good (it is not difficult to distinguish from the bright flash of a short circuit), the wire starts to warm up, and then the engine starts, the candles here at anything. Problems to be found in electrical circuits, voltage feed on them. This way you can also check the fuel supply valve.

And finally, the only blame yourself if it tried to start the car on the move. Timing belt at the same time could easily slip a few teeth. Start the engine and can not, you may need to prepare for the complex and costly engine repair.

As experience shows, it is very common and is a different situation - the engine is idling, and when you try to add revolutions immediately stalls or stops almost worked. Most likely, the fuel system is air. It should once again draw attention to the exhaust. In this case, it is usually white with a characteristic smell of diesel. The vacuum in the fuel stream can arise due to blockage, for example, fuel standpipe or fuel filter. Most often it is the fuel filter is clogged, with such troubles occur mostly in the winter.

The vacuum in the fuel stream can arise due to blockage, for example, fuel standpipe or fuel filter. Most often it is the fuel filter is clogged, with such troubles occur mostly in the winter.

The company's specialists "Tehnodizel" advised to adhere to all rules, no exceptions, never repair the fuel filters. A variety of "washing", "blowing", and others, ostensibly restoring procedures, at best simply will have no effect, and at worst - even aggravate the situation. Fuel passes through a "restored" filter, not only receives the cleaning position, but also washes out of the filter all the accumulated dirt in it before. It's pretty fast can damage the precise mechanism of the high pressure pump.

Another psevdopomosch motors that provide like "know" mechanics - installation of several fuel filters. From the standpoint of achieving an unprecedented purity of diesel fuel into the engine of meaning in this multi-stage filtration no. Manufacturers have diesel vehicles is carried out precise calculations of performance filters, which are supported by the whole series of tests, so they should trust. More filters not only useless but harmful. They create excessive resistance, whereby the pump works with congestion and quickly breaks down. The increased resistance in the pipe can also cause air suction.

You should not go on about, and another fairly common misconception that the additional filters promote separation of water from the fuel. In fact, the filters do not retain water, for this purpose there are special sedimentation separators. The presence of such a separator indicates a small tube under the filter bottom. Drain accumulated moisture should be approximately every 3,000 kilometers. Drain the liquid should be as long as the flow is almost pure diesel fuel.

The presence of water also causes the fuel exhaust white clouds. Some modern diesel cars have an indicator on the instrument panel, which tells that there is water in the fuel. If the indicator lights up, it is better not postponing, stop, switch off the engine and drain the liquid from the separator. If necessary, repeat the procedure. Then, if the indicator does not want to fade, it is likely that a problem in the electrical circuits of the system indicating the presence of water in the fuel. Trying something to correct them in a hurry is not necessary, it is better creep into auto repair.

Sometimes, such that approximately gudevshy engine suddenly for no reason at all stops. Most trivilny Council, which, oddly enough, helps in many "serious" cases, - make sure that the tank still has a diesel fuel. If the case is worse, and something really happened, it is worth to recall whether there was any sharp sound before the engine stopped. So the sound is accompanied by a broken timing belt. If so, you'd better not try to scroll through the engine - the consequences could be devastating.

Another reason for the sudden stop of the motor can be all the same air in the fuel system. You can try to directly connect the pump to the fuel tank with diesel fuel each. If the engine starts to work, the cause is found. If you experience problems with the fuel pump is best to consult specialists, not trusting questionable repair mechanics.

When the pump is excluded from the possible perpetrators of trouble, you can try to weaken the unions on the injectors. If during attempts to start the engine from the pulsating jet of them starts to flow diesel fuel, which means that the faulty injector does not allow the normal flow of fuel into the combustion chamber. Did you notice that threw black smoke exhaust - is one of the signs hang in the nozzle needle. Fuel begins uncontrolled flow into the cylinder, and the exhaust is black due to its incomplete combustion.

And one more thing - do not need to go dashing through deep puddles. Masters often seen crippled after such bathing motors diesel cars. The water from a puddle gets into the combustion chamber, and a strong hydrodynamic blow bends even Robust rods!
