Diesel engine "YaMZ-530": technical characteristics, device and operation
Since December 2013 Yaroslavl capacities of JSC Avtodizel have been producing diesel units of the YAMZ-530 family. This includes only two models of engines - four- and six-cylinder engines.
In our country there are a lot of enterprises producing trucks, various sizes of buses, as well as many options for special equipment for construction and agriculture. That all this could work, it is necessary to provide the units with engines. At the same time it is desirable that these diesel engines have a large life cycle and that they comply with the norms of "Euro-5".
The purpose of this project is to create a true universal platform on the basis of which it will be possible to produce power units for the most diverse equipment in the agricultural and construction fields. It is known that in order to build a special version of the motor for the tractor, many different additional tasks will be required. Often it is necessary to process some details. However, specialists of the Yaroslavl plant give a guarantee that in order to use this engine, there will not be any constructive changes.
A risky but successful step
At the Yaroslavl motor plant, they really took the risk. After all, to create a diesel engine "YaMZ-530", which would not only have unique characteristics, but could create competition for the best models of world manufacturers, is very, very difficult.
To this end, in the middle of the 2000s, European engineers were invited as partners in this project. After several years of development and experimentation, a series of in-line motors with a volume of 1.1 liters per cylinder was created.
By the way, this engine is one of the first in the whole history of domestic engine building. This product has become a novelty not only for the whole country, but also for "Autodiesel". After all, not only the latest design, but also other methods of designing and developing. As a result, it was possible to create a power unit called "YaMZ-530", whose reviews are mostly enthusiastic.
Scheme
Scheme for the new engine decided to choose a lower one. Both domestic and European experts unanimously said that it would be better for medium sized diesel engines with small turns.
The engine is fairly compact. The fault is the lack of camshafts in the cylinder head. And the head of the block of cylinders does not differ the big height and other sizes. Also in this motor is not found and a long drive gas distribution mechanism. Engineers were able to significantly reduce the weight of moving and rotating assemblies and parts. The design itself, compared to other modifications, has become much more reliable. The operation of the unit is quite quiet and differs in increased durability. All the most important nodes receive movement from the crankshaft drive. This makes it possible to minimize rotational oscillations to a large extent.
Raisins
Among the interesting moments in the design of the YaMZ-530, one can single out a cooling system with the possibility of a reverse stroke. So, the cooling liquid gets not habitual for many way - from below upwards, and from above downwards.
Engineers used the technology of wet cases in this power unit. For production, it turned out to be a little inconvenient, however, as practice showed, the cylinders are cooled more evenly. Cylinder piston group has a greater resource. If it is necessary to replace something, there is no need to bore the cylinders to the desired size. You can immediately install the nominal parts. The resource, according to the developers, is more than a million kilometers. This is an impressive figure.
The best accessories
Developing a new diesel "YaMZ-530", the specialists applied the best components. Just imagine, the fuel equipment was ordered from the leaders of the industry - Bosch, the details for the piston group were supplied by Federal Mogul, the block of cylinders - Fritz Winter. Valve biscuits, as well as liners - and those imported, made by the famous manufacturer Mahle.
Efficiency and versatility
The power diesel unit YMZ-530 is the embodiment of the most advanced and advanced solutions. There is a unique scheme of fuel supply of the battery type. Controls this electronic control system. All parts were made with the expectation of working under high pressure.
Lubrication system, as well as effective cooling, allow to get a liter capacity up to 34 kW. Drive on the basis of gears from the flywheel side makes it possible to make the operation of the unit almost noiseless. The ventilation system of the crankcase gases of the closed type is fully integrated into the cylinder head cover. No longer will it have to be serviced.
One of the advantages of this diesel engine is its high compactness and low weight. This makes it much easier to install it in the engine compartment of the truck. The developers were able to put into the design various options. This is the possibility of installing a compressor for the air conditioner, pre-heater, as well as the cabin heater.
Motor, dictating new standards
The unit is extraordinarily reliable. The resource is very high. The intervals between services are up to 50 thousand kilometers. This is the way to reduce maintenance costs by almost half. The technology with these motors is characterized by high environmental friendliness, quiet operation and comfort.
The device and work of YaMZ-530 immensely please owners. The level of vibration and noise is not more than 92 dB. This allows you to permanently abandon the rather expensive hooding of the engine compartment, and also enhances the comfort for the driver in the cab or for passengers on the bus.
Economical as import
The low level of fuel and lubricant consumption is fully confirmed in numerous tests.
Dynamic and efficient in motion
The technology, which is equipped with these power units, has significant advantages. High torque up to 1226 Nm, available at low revs, allows the car to move very dynamically. The machine is easily accelerated, and it is easy to control.
Design features
In order to achieve high levels of environmental friendliness, engineers applied a special system - EGR. It improves the process of gas recirculation. Also in the design there is a catalyst with the possibility of replacing filters.
Follows the parameters of the new control unit. The motor is equipped with a set of sensors that are sensitive to the condition of all the main components.
Engine "YaMZ-530": specifications
Let's see what the basic version of this engine is capable of. So, this is a four-cylinder, four-cylinder power unit. Its working volume is 4.4 liters. Depending on the modification, the power can vary from 136 to 190 horsepower for a four-cylinder version.
The number of revolutions of the crankshaft for the basic unit is 2300 rpm. The maximum torque is 710 Nm at 1600 rpm. As for the fuel consumption of YaMZ-530, the characteristics show that the appetite of the unit is 143 grams per horsepower per hour. It's pretty technological. The engine's weight is only 480 kg in the base version.
The six-cylinder version has better characteristics. The volume of the unit is 6.6 liters. On equipment this version is a complete copy of the four-cylinder. Here, the same drive units, the same cooling system, installed turbocharging.
Power depending on the modification will be from 270 to 312 horsepower. The torque in this version is 1226 Nm at 1600 rpm. The minimum fuel consumption is 194 grams per 1 horsepower per hour.
Certified for Euro-5
Yaroslavl plant Avtodizel, where they manufacture such units, successfully received certificates for the engine YMZ-530, the characteristics of which fully comply with the new environmental standard. This allowed to significantly expand the export capabilities of cars, which were equipped with such installations in European countries.
The new line under "Euro-5" differs significantly improved characteristics, technical and economic indicators. The power range also expanded. Now it is from 240 to 330 horsepower. Torque also expanded - from 900 to 1370 Nm.
By their design, the "Euro-5" models are almost completely unified with their analogous "brethren" under the previous standard. To fully comply with the latest environmental standards, the design uses a catalytic reduction system.
The first copies were sent for testing to the strategic partners of the GAZ Group. They will be installed and operated on many cars, such as Ural, MAZ, and these units will be equipped with city and suburban buses of the brand "LiAZ".
The production was placed in new areas. All parts are made on the most modern machine tools. The new production site uses the most advanced technologies that provide reliability and economy.
What do the owners say about the design of the YaMZ-530? The engine receives only positive feedback. These engines have some advantages that many foreign manufacturers do not have. So, the Yaroslavl unit considerably wins on twisting moment and power. At the same time, fuel consumption is quite low.
So, we found out what the engine "YAMZ-530" has technical characteristics and reviews. The acquisition of this device will be a win-win investment of money. Such an engine will last long and efficiently, which is the paramount task of such units.
