New volvo xc60 how a diesel engine works. New comment

26.03.2022

"Diesel" is such an engine that is quite changeable in cold weather. The operation of a Volvo diesel engine in winter leads it to a state of "anabiosis" - the viscosity of the fuel increases, the evaporation process decreases. Frosty air penetrates into the cylinders, does not contribute to the settlement of the negative conditions that have arisen.

To activate the fuel mixture in the circumstances that have arisen, the maximum return of the cylinder-piston group, fuel equipment, glow plugs and battery is necessary. Let's add to these problems such moments as thickened oil and increased resistance when starting the engine. But professionals are in a hurry to reassure: a volvo diesel engine, which is in working condition, should start immediately in winter, without prolonged warming up, until the temperature drops to -30? C. Can this be achieved? In principle, everything is simple.

The most important thing is sensitivity to the diesel engine.

There are, in principle, few circumstances under which a diesel engine does not start well in winter. One of these reasons is:

Poor quality fuel
its incorrect distribution,
bad compression in the motor,
poor functioning of the glow plugs or battery.

In the event that problems are eliminated in time, the Volvo diesel engine will start at low temperatures, like a gasoline engine.

Battery.

In this case, a brief explanation is needed. It's no secret that the ignition of a Volvo diesel engine is carried out during the compression process. It is very important at this point that the battery not only cranks the engine, but does it with absolute certainty. Always remember that a significant proportion of the battery current goes to warm up the glow plugs. But in this regard, diesel engines require batteries with increased starting currents. The more powerful the current, the better. Professionals strongly advise using batteries with a starting current of at least 320 A on diesel engines. A battery that has been used on a diesel engine for more than three years must be replaced. On the eve of the onset of the winter period, it is required to check the electrolyte level and the properties of the contacts on the battery and starter terminals. It is recommended to eliminate oxides, and treat the clamps themselves with conductive grease.

glow plugs.

Glow plugs also play an important role in the operation of a Volvo diesel engine in winter. It is necessary to make sure in advance that the glow plugs are in working order, since too cold air enters the cylinders, and without a high-quality heating of the combustion chamber, it will not be possible to start the Volvo diesel engine. Before starting a diesel engine in winter, glow plugs are recommended to be lit and extinguished several times, as this will help warm the air properly. These operations allow you to start a volvo diesel engine in a short period of time.

By the way, for a motor with non-functioning glow plugs, the winter season begins already at a temperature of + 5 ° C. In the event that the air temperature drops to zero and the engine does not want to start, then you first need to pay attention to the glow plugs. Even in the event that one glow plug is out of order, it is recommended to update the entire set, especially before the onset of the winter period.

The service life of glow plugs is about five years. When this period expires, the possibility of burnout of the spiral increases sharply. To find out if the glow plug is in working order or not, you should unscrew the candle from the head, give a "plus" to the candle clamp, and a "minus" to its core. At a candle that is in working condition, after a few seconds, a special incandescent tube will heat up to such a state that the candle will glow. But if the procedure did not give positive results, then be sure to replace the candles.

Restless signals.

Alas, the owner of a car with a diesel engine is not always able to identify the state in which he is without outside help.

In the summer, the engine is able to function completely smoothly - it starts quickly, runs neatly and smoothly, but if the thermometer drops to -15 ° C, the Volvo diesel engine simply does not want to start.

Sensitive to his car, the driver will definitely pay attention to the restless signals coming from the motor. In the case when, during slight frosts, the motor happens to “twist” for a long time before starting, first of all, you should pay attention to the engine. Most likely, it needs to be examined. If the thermometer drops below -15 ° C, then the faulty Volvo diesel engine will simply refuse to work. The existing problems in the fuel system are openly indicated by the uneven functioning of an unheated engine, and a decrease in throttle response, an increase in fuel consumption, and an increase in smoke.

In addition, those diesel engines that have traveled more than 100,000 kilometers are also unreliable. It's like botox, you wear it longer, you like it less. These engines often experience problems with compression in the cylinders during winter operation. A common factor in the occurrence of this problem are obsolete piston rings and cylinder liners.

Drivers whose cars are equipped with engines with a common rail fuel system should take care of the engine preheating system in the winter season. Engines with a Common Rail system are much harder to endure Russian winters than engines with a classic fuel system. Experts advise starting these engines only with preheating.

The battle with low-quality diesel fuel

Can we safely say that the diesel fuel offered at gas stations is of high quality. The problem of diesel fuel quality is not so urgent today, but it still exists. Even today, there are cases when water and paraffins are added to diesel fuel. Inside the city, such cases are rare, but outside the city - this happens quite often. I would like to advise city car owners not to buy, as they say, diesel fuel from their hands. In the event that there is a feeling that you have been filled with low-quality fuel, do not wait until the volvo diesel engine fails, because this will happen quite quickly.

An increased water content in diesel fuel can be detected using special sensors located on the instrument panel. In the event that the control lamp lights up, it is necessary to remove the accumulated water in special tanks - settling tanks. Experts recommend removing excess water from septic tanks systematically in order to prevent malfunctions. To do this, empty the sump every 3,000 kilometers of operation.

Winter auto-chemistry for diesel engines.

Currently, there are special preparations on the shelves of auto stores that help to operate a Volvo diesel engine in the winter season. Of these, motorists often purchase a moisture displacer. The purchase of such a drug does not "hit the pockets", but it is very effective. This drug leads to a decrease in the temperature of the thickening of the fuel, and also relieves diesel fuel from excessive water content.

Professionals do not recommend the frequent use of aerosol cans with fast-flammable components. Even a slight excess of this composition can result in serious consequences for the Volvo diesel engine. There have been cases when, due to too early ignition of such a composition, all pistons in the engine broke.

Volvo XC60 appeared swiftly. They just showed his concept in 2007, when only six months later a serial model was released, which remained practically unchanged until last year's restyling. And, in fact, no changes were required. The crossover turned out to be both okay and successful from a technical point of view. This, by the way, is not surprising, since he shares the platform and a number of units with bestsellers in their fields - Land Rover Freelander 2 and Ford Mondeo ...

The platform itself was developed by Ford and, with some upgrades, survived up to the Land Rover Discovery Sport. Yes, our "Swede" walks in the uncles of the current novelty of the "green oval"! The paths of the global automotive industry are inscrutable.

THERE IS NO MUCH DIESEL
Three variants of diesel engines were installed on the Volvo XC60 at different times. The weakest and most economical is the 136-horsepower D3 with a working volume of 1984 cm3. Two engines of the same volume of 2.4 liters, but with different power, 181 and 215 hp. with., differ in indices - D4 and D5. At the beginning of the crossover, there was only one diesel engine - 2.4 liters and a capacity of 163 hp. With. - the option is not the best. By the way, the difference in output between the last two motors is easily compensated by chip tuning (about 20,000 rubles). You can also chip D3, but there are an order of magnitude more dissatisfied with the result. They complain about the sharply increased waste of oil - up to a liter per 1000 km - and the frequent inclusion of an indicator that requires a motor service. All diesel engines are extremely critical to the quality of the oil, but with timely and accurate maintenance, they serve 150,000 km without frightening problems. Little things can bring you out of balance. The truth is that the devil is in the details, and when you replace a leaking radiator hose or crankshaft position sensor for the fifth time, this old adage will seem very true. The sensor costs 2000 rubles. with a replacement, the tube is even smaller, but the floating quality of the components does not compensate for these prices ...


Design. Spacious, comfortable, beautiful and expensive.
True Scandinavian style!

With gasoline engines, the picture is exactly the same. True, there are two of them - four- and six-cylinder. Designated T5 and T6, equipped with turbines and have a volume of 2.0 and 3.0 liters, respectively. Power - 245 and 304 liters. With. - allow you to feel confident both in the city and on the highway. In contrast, the weakest diesel, according to the owners, does not provide proper elasticity and turns dynamic overtaking into a tickling event. Gasoline in this sense are good, although even the one that is smaller in volume is able to gobble up 16 liters of fuel in the city. Gasoline engines have no special problems, except for the same lottery with components. Unless the smaller one is prone to the formation of carbon deposits on the valves, if not very high-quality oil is poured in, and the quick demise of the particulate filter can be called a common problem. Well, of course, since the motors are equipped with turbines, you need to give them time to cool down or put a turbo timer. In 2010, almost all engines were boosted a little by changing the settings.

CAN ALL OR NOTHING
Volvo's handling can be described in many ways. And radically different. To one it seems that the XC60 is not controlled, does not slow down and does not accelerate. Another will call behavior on the road confident and stable. Swedish crossovers, like no other, require a clear understanding that a car is first and foremost a means of transportation, and a toy and entertainment are third and fifth ... We can admit that the sport component in setting up the suspension and steering in the Volvo XC60, of course, more than in the imposing XC90, but it still doesn’t pull on a rally car even in dreams. But the chassis of both is extremely reliable, which is a rarity in our time. Usually, crossovers on a passenger platform, and most of them, begin to rumble with the suspension already in the first dozen thousand kilometers. This is where the interior will rumble. After the first hundred thousand run, you should pay attention to the rear silent block of the McPherson front suspension and the bushings of the lower arm of the rear multi-link suspension. And also on very cheap stabilizer rubber bands. By the way, I heard about attempts to replace shock absorbers with stiffer ones. More often than not, this only reduces comfort without any noticeable improvement in handling. If we really change, then the brake discs, which after the winter can begin to beat on cars with powerful engines and among fans of a sharp ride. It is not necessary to install Brembo Gold, but it is worth climbing the forums in search of a good option ...

FAIL-FREE "AUTOMATOMS"
The Volvo XC60 was equipped with both manual and automatic transmissions. Since the vast majority of automatic transmissions, and you won’t even find “mechanics” on purpose, let’s touch on automatic transmission. Actually, there is also nothing special to talk about here ... Geartronic “Automatic machines” are a model of reliability. If problems occur with them up to 200,000 km, then this is either the result of sloppy maintenance, inaccurate operation, or just an unsuccessful instance, which, I repeat, happens extremely rarely.

The drive can be front or full with a Haldex clutch. The unit is just as reliable, overheating or jamming is unfamiliar to him. When choosing a car, you should pay attention to all-wheel drive versions, since the difference in cross-country ability is radical. In general, off-road Volvo feels very confident. It is not for nothing that his family has such famous rogues as the Land Rover Freelander, even though it is a crossover. However, if the "British" on rough terrain can be found all the time, then the "Swede" in the swamp is an extraordinary phenomenon. However, it has 225 mm of ground clearance, good approach and departure angles, a well-protected bottom and a competent traction control system. There is a hill descent assistant and a switchable stabilization system. "Volvovittsy", however, know that their offspring will not stick in the dirt for nothing, and the car was not equipped with any additional off-road systems.


METAL AND WOOD

Salon Volvo XC60 bribed more than one thousand buyers who came to look at him in the store. This is the case when wealth is not vulgar, but cozy and not pretentious. Ergonomics on top, interior materials too. Gorgeous leather and wood trim. Only plastic is lame, which looks good, but is easily scratched. Over time, however, the skin can become covered with wrinkles and even small cracks. If you want to avoid this, use special leather conditioners.

All in all, the Volvo XC60 is a very high-tech car with a lot of options, quite complex and expensive to repair. Even a failure of the rear door electric sensor can lighten the owner's wallet by 5,000 rubles. Such failures occur extremely rarely, and I mention them not to scold the crossover, but to warn: try to be serviced by qualified craftsmen. In this case, the miser pays twice. Moreover, the conditions for warranty repairs for the Swedish crossover are such that almost all breakdowns, even the smallest ones, are resolved at the expense of the manufacturer. However, this does not negate the accuracy when choosing a used car.


OWNER'S OPINION: ANATOLY, VOLVO XC60 2.4 D5, AT, AWD, 2012
Reading positive and negative reviews of the XC60 on various resources, I put marks in two columns in a notebook. And for about 50 enthusiastic notes, there were two sharply negative ones. And so much so that there was an impression that this was an order from competitors ... I can put a tick on the side where everything is fine. Diesel, four-wheel drive, comfort, confident movement in the worst weather - in a word, I get what I expected from the car. Yes, it doesn't break. At all!

The domestic car market from year to year is replenished with new brands and models of crossovers. Not so long ago, namely in 2008, a new model of the Volvo brand appeared - the Volvo XC60. For the first days of operation, many drivers appreciated this car. Of course, to this day, Volvo has a lot of advantages, but, unfortunately, during the operation, weaknesses, illnesses, and shortcomings of this car, which every potential buyer should be aware of, were identified.

Weaknesses of the Volvo XC60

timing belt;
Turbine;
Particulate filter;
Fuel pump;
Other, but not critical.

On Volvo XC60 vehicles with a timing belt drive, it is important to pay attention to the condition of the belt. Considering that the first Volvo XC60 in most cases have a mileage of more than 100 thousand km. it is imperative to make sure when the belt was last changed on the car you are buying and whether it was replaced at all. If not, then in the near future it will need to be done by the buyer. In the event that the Volvo XC60 has a timing chain drive, it is also important to make sure that the chain is not stretched. It is important to remember that a broken belt or a strong chain stretch, depending on the car you buy, will lead to very serious consequences for the engine.

A turbocharger, as you know, on any car in the event of its failure will cause a lot of trouble for its owner, ranging from its availability for purchase to its cost and price of work. On a Volvo XC60 with turbodiesel engines, the condition of the turbine must also be diagnosed first when buying. If this is not possible, then you can determine its condition by indirect signs, and these are: increased smoke, a drop in power during acceleration, the smell of oil fume, increased noise, etc.

Particulate filter.

The particulate filter on cars with diesel engines can also cause a lot of trouble to the future owner, and at the most inopportune moment. It should be understood that replacing the particulate filter or removing it costs a lot of money. Therefore, by indirect signs, one can also determine its condition. Whether he is beaten or not. The main alarming symptoms of a clogged filter are a problem with starting the engine, increased fuel consumption and floating speed.

Fuel pump.

The fuel pump on the Volvo XC60 often caused problems for the owners of these cars. It certainly can even be called not only a weak point, but a disease of the Volvo XC60. But it is important to clarify that basically not the pump itself, but the electronic control module for this unit. Therefore, in case of malfunctions of both the pump itself and its control module, the following symptoms will appear - problems with starting the engine, a change in the tone of the engine, or even a sudden stop of the engine. Therefore, when buying, it is important to make a test drive on the car you are buying and check the presence or absence of these signs, both after launch and in motion.

The above are the main weaknesses that you must first pay attention to and be aware of them before buying. The rest of the elements, like suspension, transmission, chassis or steering, are not weak points or are, but their replacement or repair will not result in a round sum to eliminate them. It is important to note that in most cases these elements fail mainly due to a limited service life, and most of them are consumables that require periodic replacement.

Disadvantages of the Volvo XC60

The creak of the drive of the fifth door;
Expensive parts;
Crickets in the cabin;
Rigid suspension;
For cars 2008-2013 problems with the windshield washer in cold weather;
On early models until 2013, the absence of a heated windshield;


In conclusion, we can say that weaknesses and shortcomings are present in almost any car, be it a crossover or a simple sedan, as they say to each his own. But the Volvo XC60 takes its rightful place among its competitors from other brands. When buying, it is important to carry out a complete diagnosis of all units, components and systems of the car in a reputable car service in order to avoid further unpleasant consequences after the purchase.

P.S: Dear owners, current and future owners of this car model, in case of frequent breakdowns and malfunctions during operation, please report it in the comments below.
