Eating system zmz 514. Crisis of the middle age. BOSCH high vise priming pump type VE

The block of cylinders is based on a special high-quality chavun, which gives the design of the engine hardness and strength.

Ducts for cooling cooling, which cool the shirt, wicking along the entire height of the block, which improves the cooling of the pistons and changes the deformation of the block due to overheating. The shirt is cooled at the top part towards the head of the block.

At the crankcase, the cylinder block has nozzles installed, which are used for cooling the pistons with oil.

Cylinder head vidlita z aluminum alloy. It has inlet and outlet valves. On the skin, the cylinder is brought along a chotiri valve: two inlet and two outlet. The inlet valves are vented on the right side of the head, and the outlet valves are on the left side. The valves are actuated by two separate shafts through hydraulic pushers. The stoppage of hydraulic pushers requires the regulation of gaps in the valve drives, as the stench automatically compensates for the gap between the cams of the split shafts and the valve stems. At the head of the cylinder block, there are seats for nozzles and candles for roasting.

rozpodіlnі Vali prepared from low carbon alloy steel. The cams of the rozpodіlnyh shafts are of different profile, roztashovani asymmetrically along their axes. On the rear ends of the shafts, branding is applied: on the intake shaft - “VP”, on the exhaust shaft - “VIP”.

At the dermal shaft there are five supporting necks. The shafts are wrapped in supports, ruffled in the head of the block of cylinders and closed with caps, drilled at the same target with the head, so the caps of the supports of the sprung shafts are not interchangeable.

In the case of axial displacements, the slatted shafts are trimmed with a half-washer, inserted into the coils of the caps of the front supports and enter with protruding parts into the grooves on the first support necks of the spherical shafts.

For precise setting of the phases of the gas expansion in the first necks of the expansion shafts, the technological openings are opened by precisely setting the crown expansions to the profile of the cams.

When the drive of the split shafts is folded, more precisely, their position is reached by the fixators, we will install in the technological opening on the first necks of the split shafts through the opening in the front krishtsi.

Technologically open the necessary ones to control the phases of the gas underflow during the operation of the engine.

On the first transitional shaft of the rozpodilnyh rolls there are two faces and a key for tightening the rozpodilnyh rolls when installing the zirochok.

pistons also suitable for aluminum alloy. On the bottom of the piston there is a marking of the diameter group of the piston back (letters "A", "B", "Y") and an arrow is applied, which is necessary for the correct orientation of the piston when installed in the engine (the arrow is right but straightened into the side of the front end of the cylinder block). At the bottom of the back of the piston there is a vikonan, as a way to ensure the expansion of the piston with a cooling nozzle. There are three grooves in the head of the vikonan piston: compression rings are installed in the two upper ones, and oil removal rings are installed in the lower one. The groove under the upper compression ring was made in the reinforcing insert from the non-resistive chavun. Three rings are installed on the skin piston: two compression rings and one oil extractor. Compression rings are good for chavun.

Characteristics of the engine ZMZ-514 2.2 16V UAZ Patriot (diesel)

construction

Chotyritactny dvigun with an electronic-ceramic system of fuel supply Common Rail, with a row of cylinders and pistons, which wrap around one central shaft, with an upper one with two roses under the shafts. The engine has a traditional cooling system of a closed type with primus circulation. The oiling system is combined: under pressure and spraying.

Cylinder block

The block of cylinders ZMZ-514 is prepared from a special chavun by a monoblock with a crankcase part lowered below the axis of the crankshaft.

Kolіnchastiy shaft

Colinshaft shaft ZMZ-514 - steel forging, five-bearing, may for short expansion of supports of high counters.

piston

The piston is made of a special aluminum alloy, with a combustion chamber, screwed into the head of the piston. Combustion chamber diameter 21.69 ± 0.4 CC. The back of the barrel-shaped piston in the late straight line and oval in the transverse section, may be anti-friction coated. The large entire oval is ruffled in a plane perpendicular to the axis of the piston pin. The largest diameter of the piston seat in the posterior band is 13 mm in the lower edge of the piston. At the bottom of the back, there is a vikonan, as a way to ensure the expansion of the piston with a cooling nozzle. The piston pin is of floating type, the outer diameter of the pin is 30 mm.

The diesel engine ZMZ-514, which looks like a distant sight, is a family of chotiric cylinder engines with 16 valves and a chotyritic operating mode. Obsyag power unit to become 2.24 liters. The back of the engine was planned to be mounted on passenger cars and commercial vehicles for GAS production, while the stink was removed widely on UAZ vehicles. Let's take a look at its characteristics, features and characteristics of Vlasniks.

History of creation

How to confirm the opinions, the ZMZ-514 diesel engine began to grow on the cob of the 80s of the last century. The designers created a new motor based on a standard carburetor analogue for the Volga. The last copy was constructed in 1984, after which we went through technical and floor testing. Appointed modification took a total of 2.4 liters, the compression ratio of the cylinders was 20.5 units.

The design has an aluminum block of cylinders, pistons made of high-quality alloy with a special relief, barrel-shaped seats, an oil filter clouding indicator, a front-heating candle, jet cooling of the piston group. The model has not been assigned to a wide series.

Already on the cob of the 90s, the designers of the Zavolzsky plant turned to the development of a new generation diesel engine. The main task put before the engineers is the creation of not just a motor based on a carburetor analogue, but the preparation of a unit that is as unified as possible with the basic prototype.

Features

Looking at pardons in the first directions and pragnennya to guarantee unification to the maximum with variation 406.10, on the "engine" ZMZ-514 (diesel) the diameter was up to 86 millimeters. A dry thin-walled sleeve was passed through the structure in a chavun monolithic block. When changing the bearings, both the root ones and the connecting rods, they did not change. In the bag, the designers reached the maximum unification in the part of the crankshaft and the cylinder block. The presence in the engine of turbine supercharging with cooled down streams was planned on the back.

The pilot letter under the index 406.10 was issued in 1995. A special small-sized nozzle for this “engine” was prepared for construction at the Yaroslavl plant of YAZDA. In addition, the cylinder head was working for aluminum, not chavun.

In the end of 1999, an experimental batch of diesel engines ZMZ-514 was produced. UAZ is not the first car, it shows up for any vin. A bunch of motors were tested on the Gazelles. Unfortunately, already through the operation, it became clear that the units are not competitive, foldable in service.

At the thought of fahіvtsіv, which at that time was in possession of the plant, they simply did not have the technical capabilities to release the motor with high performance characteristics. In addition, the completing parts also called out a lack of confidence, the shards were supplied from different manufacturers. As a result, the serial release was burnt out, in fact, without doing yoga.

modernization

Undaunted by the difficulties, the upgrades and improvements to the ZMZ-514 diesel engine continued. Changed the configuration of the BC and cylinder heads, with one-hour adjustment of their hardness. In order to secure the day of the gas joint, they installed a metal bagatorium gasket of foreign production. The piston group was brought to its senses by fahivts of the German company Mahle. Also, the timing chains, connecting rods and anonymous insignificant details were added to the upgrades.

As a result, the serial production of updated diesel engines ZMZ-514 began. UAZ "Hunter" - the first car, they began to install mass engines on yak qi motors in 2006. Since 2007, modifications have appeared with elements like "Bosch" and "Common Rail". Upgrading specimens were ten times less than diesel fuel and showed a shorter pickup rate at low speeds.

About the design of the diesel engine ZMZ-514

"Hunter" otrimav chotiritaktny motor with in-line L-like placement of cylinders and piston group. At the top roztashuvannі bet rozpodіlnyh valіv, wrapping zabezpechuvav one kolіnval. The power unit was equipped with a closed cooling circuit with a primus stove. The oil of parts was made in a combined way (by supplying under a vice and spraying). In the renovated engine, a valve was installed on the skin cylinder, with which it was cooled again through the intercooler. Turbine is not brought to the ideal, it is tested by practicality and ease of maintenance.

"Boshovsky" nozzles are built in a double-spring vikonann, to give the possibility to secure the front feed of the burner. Among other details:

Crank Vuzol

Notes about ZMZ-514 diesel engines point to those that the block of cylinders is crushed from a special chavun in a monolithic design. The crankcase part is lowered below the axis of the crankshaft. For the refrigerant, the flow-through sockets between the cylinders are transferred. Below there are five supports of the main bearings. The crankcase has nozzles for oil cooling of the pistons.

The head of the cylinders is vikonan with an aluminum alloy with a straight line. In the head of the cylinder head there is a hydraulic mechanism that consists of drive valves, rozpodilny shafts, hydraulic bearings, inlet and outlet valves. Also in the designated part there are flanges for connecting the intake pipes and collectors, a thermostat, a cap, candles for heating, cooling elements and oil.

Pistons and liners

The pistons are crushed from a special aluminum alloy, with a spark of fire, a kind of sporulation in the head. The barrel-shaped seat is equipped with anti-friction coatings. On the skin element, there are a couple of compression rings and one oil-removing analogue.

The steel connecting rod is made by the forging method, this cap is assembled in assembly, it is not allowed to replace them with each other. The shutter is fastened with bolts, a bushing made of sumish steel and bronze is pressed into the piston head. Kolіnval - steel forging, may five supports and vіsіm counterag. Vіd znos necks of protection for gas nitriding or HDTV hardening.

The bearing bushings are made from steel and aluminum alloy, open the channels on the upper elements of the transfer channel, and the lower analogues are smooth, without any twists. On the flange of the crankshaft, the flywheel is attached to the rear with eight bolts.

Smearing and chilling

In the comments about diesel engines ZMZ-514 on the UAZ "Hunter" it is noted that the engine oil system is combined and richly functional. All bearings, drive parts, important bearings, tensioners are under a vise. Other details that rub the engine are processed by spraying. The pistons are cooled by jet oil supply. Hydraulic supports and tensioners in the working camp are guided by the supply of oil under a vice. One-section gear pump is mounted between BC and filter.

Cooling - native closed type with primus circulation. The refrigerant is supplied to the cylinder block, processed in a thermostat type 3 with solid filling. In the system, there is a central water pump with one valve, a V-belt, a service for transferring energy from the crankshaft pulley.

gasozone

Rozpodіlnі elementi (valley) made of alloyed steel with low carbon instead. The stench was stably wound to a depth of 1.3-1.8 millimeters, the hardening went ahead. In the system, a pair of sub-valves was transferred (assigned to drive the inlet and outlet valves). The cams of a different profile are ruffled asymmetrically to their axis. The leather shaft is equipped with five support pins, wrapped in supports, as if they are rebuyed in the head with aluminum. Details are covered with special caps. At the top of the shaft, the shafts are driven behind the help of a two-stage lancet drive.

Characteristics in numbers

Here are the first few comments about ZMZ-514 diesel engines, let's take a look at the main technical parameters:

• working volume (l) - 2.23;
• tension nominal (c.s.) - 114;
• spritnіst (about / hv) - 3500;
• maximum torque (Nm) - 216;
• cylinder in diameter (mm) - 87;
• piston displacement (mm) - 94;
• compression - 19.5;
• valve expansion - a pair of inlet and two outlet elements;
• stand between axles of summ_zhnyh cylinders (mm) - 106;
• diameter of connecting rod / root pins (mm) - 56/62;
• weight of the engine (kg) - 220.

elegant hunter

As you can see, post-ashlyahoviks are considered to be used by important workers. The stench is the fault of the mother's song of perevagi, as if to allow them to go overboard in the minds of an important off-road. Sob the car is inspired by the depressions, you will need an exhausting engine and a new drive.

I realized that with such vimogi, the vitrata of the paliva increases. Not all off-road lovers are ready to spend pennies on gasoline. That is why the auto industry has begun to virolyat the UAZ Hunter diesel.

What is a diesel UAZ

UAZ Hunter is the fall of the time-worn UAZ 469, which is popular among car enthusiasts of the Donin. The very same became the main cause of Hunter's cob. The car cannot boast of a prestigious design, but its technical characteristics ensure high sales.

Hunter with a diesel engine, having removed all the best qualities of his predecessor. At the same time, sprat polypshen was introduced into the design of the pozashlyahovik, as they allowed it to be raised in a different way. For example, the mechanism of closing the doors has been realized, now the stench is curled up just to make noise without any noise. The hull was covered with expensive enamel, as if looking like a modern look to a zashlyahovik.

In order to improve the road clearance, they lifted the car's bottom and sounded the door opening. It’s lightly pushed into the comfort of the sky, it’s become less easy for the rocks to get into the cabin. The seats became more anatomical, which allowed for more space in the cabin. Now, in the back, you can add additional seats, and the baggage compartments can be equipped with front doors, like on modern zashlyahoviks.

Hunter did not have a small number of 469 models, among which the design of the checkpoint and the low pressure of the motor were listed. Modernization of the diesel zashlyakhovik Volodya with offensive advances:

• salon becoming more comfortable and comfortable;
• signifi- cantly lowering the pale vitrata;
• engine and transmission modernized;
• the design scheme of the suspension has been reduced;
• zbіlshilisya obsyag salon and vantazhopіdyomnіst.

Diesel engine to make cars more maneuverable

Vіdguki vlasnikіv vіdchat about those scho avtomobilіl becoming rich functional. Yogo can win not only in the minds of off-road, but also in the capacity of a family car for views on nature.

Numerical look at the zashlyakhovik confirmed that the new one was equipped with a 5-speed manual gearbox manufactured by Hyundai Dymos. The checkpoint of this brewer is of high quality, significantly overturning the characteristics of the vinaigrette analogue.

Advantages of a diesel engine over a gasoline engine

Depending on the type of engine - diesel or gasoline, it is necessary to check the relevant information between them.

Petrol Hunter is equipped with a 4-cylinder 16-valve engine ZMZ-409 with a capacity of 128 liters. With. and volume 2.7 l. The brewing plant recommends refueling the engine with AI-92 gasoline. Vitrata Paliva stores 13.2 liters per 100 km in a mixed cycle. Pozashlyahovik develops speed, which reaches 130 km / h.

The diesel Hunter has a 4-cylinder 16-valve engine ZMZ-514 with a capacity of 114 liters. With. and volume 2.2 l. The average vitrata paliva per 100 km stores a total of 10.5 liters. UAZ building rozganyatisya up to 120 km / year, developing a torque that reaches 270 Nm.

Vihodyachi s tsogo, you can stverdzhuvati s upevnenistyu, scho diesel engine allows you to spare not only for more cheap type of fire, but also on yogo vitrati. With this, the maximum speed of the ZMZ-514 is not enough to program the speed of the ZMZ-409. The price of an economically-priced oil-burner outweighs the var- tity of a gasoline Hunter by 50 thousand. R. Savings on gasoline to pay off the overpayment already after 20 thousand. Km I'll go.

Diesel engine makes auto tightness

For an hour of operation, the diesel engine does not react to the passenger involvement of the car. The results of the test drive showed that the economical motor does not overheat like in Russia on asphalt pavement, so even before an hour of important off-road driving. With a different gasoline engine, the problem has been present even before.

The ZMZ 514 diesel engine is manufactured at the Zavolzsky Motor Plant, and is the only representative of the diesel engine in the entire engine line of this type. The power unit is usually used for vintage cars, which are issued by the GAZ group of companies, and also the main mass of engines bought by UAZ, for installation on their own cars.

Technical characteristics

Diesel ZMZ 514, firstly developed specifically for GAZ vehicles, later becoming the best for cars of the Ulyanovsk Automobile Plant. In the process of upgrading, the motor became more superior and increased the tightness of the characteristics.

Rozglyanemo, ZMZ 514 diesel and technical characteristics:

The main part is installed on transport facilities prepared by the Ulyanovsk Automobile Plant, and itself: UAZ Patriot (Diesel), Hunter, Pickup and Cargo.

Modifications of the power plant

Servicing the power unit

Maintenance of the 514th internal combustion engine is carried out as usual, as for all domestic diesel vehicles. The average service interval should be 12,000 km, and more experts and motorists converge to the point that for saving and improving the resource, it is necessary to change this figure to 10,000 km.

When carrying out technical maintenance, glass materials and oil are changed. Before the first point, it is put - a coarse and fine oil filter, as well as a shower filter. It is also recommended to recheck the filter after 15-20 km, we will fill it up after 15-20 km.

Special respect during the technical maintenance, especially if it is carried out with your own hands, varto turn on the injector station, the glow plug, as well as the high vise pressure pump station.

An unforeseen repair of the rest can lead to more serious damage to the plunger, which can cause additional capital investment.

visnovok

Diesel engine ZMZ 514 having achieved a wide popularity in the transport facilities of the Ulyanovsk Automobile Plant. Simplicity of construction, typical for all motors produced by the Zavolzky Motor Plant, allows you to simply and easily repair the motor yourself. Maintenance of the power unit is carried out for 12,000 km.
