Since December 2013, diesel engines of the YaMZ-530 family have been manufactured at the Yaroslavl facilities of Avtodiesel OJSC. This includes so far only two models of engines - these are four- and six-cylinder engines.
In our country there are a lot of enterprises where trucks are produced, buses of various sizes, as well as many options for special equipment for construction and agriculture. In order for all this to work, it is necessary to provide the units with engines. At the same time, it is desirable that these diesel engines have a long life cycle and that they comply with Euro-5 standards.
The aim of this project is to create a real universal platform, on the basis of which it will be possible to produce power units for a wide variety of equipment in the agricultural and construction sectors. After all, it is known that in order to build a special version of the engine for a tractor, many different additional tasks will be required. Often you have to recycle some details. However, specialists from the Yaroslavl plant give a guarantee that in order to use this engine, no design changes will be necessary.
A risky but successful move
At the Yaroslavl Motor Plant really took a real risk. Indeed, it is very, very difficult to create a YaMZ-530 diesel engine, which would not only have unique characteristics, but could create competition for the best models of world manufacturers.
For this, 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 engines was created with a volume of 1.1 liters per cylinder.
The same volume, by the way, on units of well-known brands such as Cummins, Volvo and Iveco. The YaMZ-530 engine also has advanced performance in terms of power and fuel consumption.
By the way, this ICE is one of the first in the entire history of domestic engine building. This product has become a novelty not only for the whole country, but also for Avtodizel. After all, here is not only the latest design, but also other methods of design and development. As a result, it was possible to create a power unit called YaMZ-530, reviews of which are mostly enthusiastic.
Schemes
The scheme for the new motor decided to choose nizhnevalnaya. Both domestic and European experts unanimously said that this would be better for medium-sized diesel engines with low revs.
The engine is quite compact. The reason for this is the lack of camshafts in the cylinder head. And the cylinder head itself is not very high and other sizes. Also in this motor you can not find a long timing gear drive . Engineers managed to significantly reduce the weight of moving and rotating nodes and parts. The design itself, in comparison with other modifications, has become much more reliable. The operation of the unit is quite quiet and is characterized by increased durability. All the most important components receive movement from the crankshaft drive. This makes it possible to significantly minimize rotational vibrations.
Highlights
Among the interesting points in the design of the YaMZ-530, one can single out a cooling system with the possibility of a reverse stroke. So, the coolant does not enter the usual way for many - from the bottom up, but from top to bottom.
So, first the hottest area is cooled - the cylinder head, and then the cylinders themselves. With the introduction of this innovation, engineers were able to achieve almost maximum efficiency. It is also worth noting the thermal stability of the dimensions of the nodes and engine parts. Tuning experts will appreciate this. Now it is possible to force any unit of the YaMZ-530 family with virtually no effort.
Engineers used wet-shell technology in this power plant. This turned out to be a little inconvenient for production, however, as practice has shown, the cylinders are cooled more evenly. The cylinder piston group has a larger resource. If you need to replace anything, there is no need to bore the cylinders to the desired size. Nominal parts can be installed immediately. The resource, according to developers, is more than a million kilometers. This is an impressive figure.
The best components
When developing the new YaMZ-530 diesel engine, specialists applied the best components. Just imagine, fuel equipment was ordered from industry leaders - Bosch, parts for the piston group were supplied by Federal Mogul, cylinder block - Fritz Winter. Crackers of valves, as well as loose leaves - and those imported, made by eminent manufacturer Mahle.
Efficiency and Versatility
The YaMZ-530 diesel power unit is the embodiment of the most modern and advanced solutions. A unique battery-type fuel supply circuit operates here. This is controlled by an electronic control system. All parts were made with the expectation of working under high pressure.
The lubrication system, as well as effective cooling, allows you to get a liter capacity of up to 34 kW. The drive based on the gears on the flywheel side makes it possible to make the operation of the unit virtually silent. The closed crankcase ventilation system is fully integrated into the cylinder head cover. You don’t have to service it anymore.
One of the advantages of this diesel engine is its high compactness and low weight. This allows you to greatly simplify the process of installing it in the engine compartment of a truck. The developers were able to lay various options in the design. This is the ability to install a compressor for the air conditioner, pre-heater, as well as the cabin heater.
Motor dictating new standards
The unit is extremely reliable. The resource is very high. Service intervals are up to 50 thousand kilometers. This is a way to reduce maintenance costs by almost half. The equipment with these motors is characterized by high environmental friendliness, silent operation and comfort.
The device and operation of the "YaMZ-530" immensely delight the owners. The level of vibration and noise is not more than 92 dB. This allows you to forever abandon quite expensive bonding of the engine compartment, and also increases comfort for the driver in the cab or for passengers on the bus.
Economical as imported
The low fuel and lubricant consumption has been fully confirmed through numerous tests.
With a volume of 1.1 liters per cylinder, the average consumption is up to 26 liters per 100 km. In this case, the car moves at a speed of 60 km / h.
Dynamic and efficient in motion
The equipment that is equipped with these power units receives significant advantages. High torque up to 1226 Nm, available at low speeds, allows the car to move very dynamically. The car accelerates easily and is easy to drive.
Design Features
In order to achieve high levels of environmental friendliness, engineers used a special system - EGR. it contributes to the improvement of the gas recirculation process. Also in the design there is a catalyst with the ability to replace filters.
The new control unit monitors the operating parameters. The motor is equipped with many sensors that sensitively monitor the status of all the main components.
YaMZ-530 engine: technical specifications
Let's see what the basic version of this motor is capable of. So, this is an in-line, 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 the four-cylinder version.

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 Avtodiesel Plant, where they are engaged in the production of such units, has successfully received certificates for the YaMZ-530 engine, 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 for Euro-5 is characterized by significantly improved characteristics, technical and economic indicators. The power range has also expanded. Now it is from 240 to 330 horsepower. Torque has also expanded - from 900 to 1370 Nm.
By their design, Euro-5 models are almost completely unified with their similar “counterparts” to the previous standard. In order to fully comply with the latest environmental standards, a catalytic reduction system was used in the design.
The first copies were sent for testing to strategic partners of the GAZ group. They will be installed and operated on many vehicles, such as Ural, MAZ, and city and suburban LiAZ buses will be equipped with these units.
The production was placed in new areas. All parts are manufactured on the most modern machines. At the new production site, the most advanced technologies are applied that provide reliability and efficiency.
What do the owners say about the YaMZ-530 design? The engine receives only positive reviews. These engines have some advantages that many foreign manufacturers do not have. So, the Yaroslavl unit significantly wins in terms of torque and power. At the same time, fuel consumption is quite low.
