When purchasing a used car, new car owners do not wonder if the equipment of the vehicle has changed. But at the first breakdown, repair becomes problematic, because the parts that are purchased for the native may not fit your unit. Moreover, without knowing the model of the engine, you cannot correctly determine the style of operation and the acquisition of the correct consumables. This is where the question of how to find out the model of a car engine becomes relevant. There are several ways to find the answer to this question.
First way
The very first thing to do is open the hood of your car and take a look at the engine. Most companies leave a special marking on its surface. For example, Mercedes company writes a special code on the unit, which begins with the letters OM and three digits. Volkswagen does exactly the same, only before the numbers there is another letter part of EA. If you find such a designation, now just enter it in the browser. On the screen you will find complete information about the engine with all the characteristics.
However, unscrupulous sellers erase in order to sell the car more expensive, declaring more powerful engine under the hood. If this happens, you can still find out which engine is worth it.
Second way
Most often, it is on the left side of the unit (possibly another location) that you can find the traditional engine number. It is very easy to find out the model by the engine number.
The first embossed character indicates the year of manufacture. Please note that on power units that were produced after 2000, the year is indicated by a letter index. The next four characters indicate the modification of the motor, and the last one indicates the climatic adaptation. Again, if necessary, enter this code in the search bar and you will find all the information about your unit.
Under this code you will see another one, for you it is of no value. If you are still interested, you can find it in the manufacturer's manual.
Third way
You can also determine the engine model by the VIN code. This code is the serial number of the vehicle and contains information about all components. This code must be affixed by each manufacturing company. Only in professional service stations can masters decipher it on the go. Therefore, use the search on the information network or a specialized directory.
Additional ways
It is worth noting that according to VIN code it is not always possible to determine the engine model. Indeed, even in the information base at the plant, an error could lurk, and the number is affixed by a person, and here the human factor plays a role.
MREO
If in the process of purchasing a car, suspicions creep in, they can be checked for diagnostics at the MREO. The car will undergo a full technical examination at a special institute. If you have a few days to spare, then this is the best way to go.
Take into account the fact that MREO has not unlimited possibilities. There are situations when it is not possible to install the engine model.
Specialized service station
Even if the MREO could not help you, then it remains to go to a specialized service center. An employee of such a center, with the help of methodological literature and his skills, will find out the model. The cost of such a service ranges from 500 rubles to 2500.
Conclusion
In most cases, you can install the engine model yourself and with minimal time and effort, without contacting specialized service stations and MREOs. Know which power unit installed in your car is very important. Identifying your engine model can save you a fortune on buying the right parts and supplies.
There are many situations when it is simply necessary to find out the engine model. For example, when buying a car or just spare parts. And then the question arises: how and where to get this information? Next, it will be told how to determine the engine model in the following ways: find the number on the motor using the engine compartment plate and the VIN code.
On the engine itself
Let's just say that looking for a number on the engine is not the easiest way. Although, it would seem: he opened the hood, found the engine, found the number and entered it in a search engine. But not everything is so simple.
Where is the engine number
First of all, the number can be stamped on a variety of places on the engine. It all depends on the make and model of the car. Although more often it can be found on the upper part, the one closer to the windshield. well and Secondly, the number itself can be in such a state that without a rust remover and a brush it is impossible to figure it out, or even completely destroyed by corrosion.
Interesting fact! In some cars made in the USA, there is simply no number on the engine. This only applies to older models.
What information is written there
As soon as you managed to find the engine number, you can begin to parse the information that it indicates. Although, depending on the brand, there are some differences, but basically the markings are 14 characters. They are conditionally divided into two blocks: descriptive (6) and indicative (8).
Notice the first one. The first three digits in the descriptive block indicate the base model index. This is followed by the modification index (if there is none, put zero), the climatic version and either the Latin “A” (meaning diaphragm clutch) or “P” (recirculation valve). In the index part, the year of issue is first indicated (by a number or letter of the Latin alphabet), then the month (by the next two digits). The remaining 5 characters indicate the serial number.
Remember! Numbers from 1 to 9 indicate 2001-2009 years of production, Latin "A" - 2010, B - 2011, C - 2012, etc.
Label under the hood
How to find out the engine model by wine, we will tell further, and now we will pay attention to the plate on which this is also indicated. It is located under the hood of most cars and is called the engine compartment. With the help of numbers and letters, all the necessary information is provided here (car model, engine type, cylinder capacity, frame number or identification number, color code and trim code, drive axle, manufacturer's plant and transmission type). Depending on the brand of the car, it can be applied in a different sequence. To decrypt, you will have to use special literature or relevant resources.
Did you know?First engine project internal combustion was introduced back in the 17th century by the Dutch inventor Christian Huygens.
Check engine by vin code
The third method will explain how to find out the engine model by the VIN code. Vehicle Identification Number (vehicle identification number), abbreviated as VIN. This number began to be assigned to cars in America and Canada. This is a unique identification number consisting of 17 numbers and letters. With it, you can learn almost everything about a particular car. And, of course, there is information about the engine model. It is enough to look into the vehicle registration certificate to find out the data (from the year of modification to the code) of the engine by vin.
Although you can do without it by looking at the code on the machine itself. Since there are no strict rules for the location of the VIN code, it can also be seen near the passenger seat. But more often it is located between the windshield and the engine.
The VIN code is divided into 3 parts of three, six and eight characters. Only numbers and Latin letters are used (except for I, O, Q due to their similarity with numbers). The first speaks about the manufacturer, the second describes vehicle, the third one is distinctive.
The first or third characters indicate the country, manufacturer and type of vehicle, that is, this is the world code of the manufacturer. In order to find out the modification of the engine by the VIN code, you need to pay attention to the second part. It will indicate the type of body, engine and model. Next, there will be a variety of information that can indicate both the type of body, chassis, cab, and the series of the car, the type brake system etc. The ninth digit of the code is a test.
The third part also contains helpful information. For example, the first character of this part (the 10th character of the code) indicates model year, the second is the assembly plant.
Important! Be sure to check the VIN code on the car and in technical passport at the time of buying. If inconsistencies are found, then you should not only refuse the transaction, but also report it to law enforcement agencies.
If you need to find out the engine model, then you can easily use the three described methods (by the number on the engine itself, on the engine compartment plate or by the wine code). Whichever method you choose, you should use special literature or online services to decipher the characters yourself.
There is a unified system for marking ship uncompressed diesel engines. The brand of the engine determines its main design features. The letters used for marking indicate: H - four-stroke; D - two-stroke; DD - two-stroke double action; R - reversible; C - ship with a reversible clutch; P - s reduction gear; K - crosshead; N - supercharged.
The numbers indicate: the first - the number of cylinders; the number above the line is the cylinder diameter in centimeters, below the line is the piston stroke in centimeters; the last digit is the order of engine modernization.
The absence of the letter K in the brand means that the diesel is trunk-type (crossheadless); if the letter P is missing, the diesel engine is non-reversible.
Consider examples of marking and brief characteristics modern marine diesel engines of domestic production.
Diesel engine 6ChRN 36/45 - six-cylinder, four-stroke single-acting, trunk, vertical, reversible with gas turbine pressurization with a cylinder diameter of 36 cm and a piston stroke of 45 cm. It is used as the main ship engine with direct connection to the propeller shaft or through a reduction gear. Rated power 900 and 1200 hp, shaft speed 375 rpm; pressurization is carried out by a TK-30 turbocharger with intercooling of the charge air.
Diesel CHN 26/26 - four-stroke single-acting, with a V-shaped arrangement of cylinders, with an undivided combustion chamber, non-reversible, high-speed, with a gas turbine pressurization; used as the main marine engine; it can be twelve-cylinder with a power range from 900 to 3000 hp. and sixteen-cylinder with a power range from 1200 to 4000 hp. at a shaft speed of 500 to 1000 rpm.
Diesel DRN 30/50 - two-stroke, low-speed, reversible, with an undivided combustion chamber; produced four-, six- and eight-cylinder with direct power transmission to the propeller shaft; valveless cross-scavenging of cylinders is performed by a piston-type scavenging pump. Supercharging is a combined two-stage one: at the first stage, it is carried out by a turbocharging compressor, the turbine of which runs on diesel exhaust gases, and at the second stage, by a drive piston pump. The rated power of the diesel engine is 750 hp, the shaft speed is 300 rpm, the charge air pressure is 147 kN / m 2 (1.5 kgf / cm 2).
Diesel 6DR 39/45 (factory brand 37D) - six-cylinder, two-stroke, reversible, high-speed, with a direct-flow valve purge system and an undivided combustion chamber. It has a power of 2000 hp, a shaft speed of 500 rpm. The purge pump is a jet, three-bladed, volumetric type.
Diesel 7DKRN 74/160 - seven-cylinder, two-stroke, crosshead, low-speed, reversible supercharged. Built in the USSR under license from the Burmeister and Vine plant. It is installed on ships as the main engine with direct power transmission to the propeller shaft. Rated engine power 8750 el.s., shaft speed 115 rpm. The purge system is a direct-flow valve with the release of exhaust gases through one valve in the cylinder head. Pressurization is carried out by centrifugal compressors driven by impulse gas turbines. The charge air pressure is about 140 kN / m 2 (1.4 kgf / cm 2). Fuel system The engine is designed so that it can run on diesel and boiler fuel.
Currently, a large number of various types of engines are in operation on ships, which are classified according to the following main features.
According to the method of implementation of the working cycle engines are divided into four-stroke and two-stroke. For the first ones, the working cycle is completed in four strokes of the piston (for two revolutions crankshaft), for the second - for two piston strokes (for one revolution of the crankshaft).
By way of action A distinction is made between single-acting, double-acting and counter-moving piston engines, in which two pistons work in the same cylinder and move in opposite directions. Depending on the design, they drive one or two crankshafts. In single-acting engines, the operating cycle takes place in the upper cavity of the cylinder above the piston, in double-acting engines, in the upper and lower cavities. Double acting engines are rarely used on ships.
According to the method of filling the working cylinder with fresh air engines are either supercharged or naturally aspirated. In supercharged engines, air with increased pressure is supplied to the engine cylinders, created by a special supercharging unit. In naturally aspirated four-stroke engines, air is sucked into the cylinders by the piston through the intake valves; in two-stroke - the cylinder is filled with air by a purge pump at low pressure.
By design Distinguish between trunk and crosshead engines. In trunk engines, the role of the guide is performed by the lower (trunk) part of the piston, which transmits lateral pressure to the cylinder walls. In cross-heads, the role of the guide is played by sliders sliding along the parallels and transferring lateral pressure to them.
In the direction of rotation of the crankshaft engines are divided into reversible, having devices for changing the direction of rotation of the crankshaft, and non-reversible, constantly rotating in one direction.
In addition, engines come in right and left models. For engines of the right model (when viewed from stern to bow, auxiliary engines- from the side of the energy consumer), the crankshaft rotates clockwise, for engines of the left model - counterclockwise.
According to the location of the cylinders engines come with a vertical arrangement of cylinders (vertical); with a horizontal arrangement of cylinders (horizontal) and with an arrangement of cylinders at a certain angle (V-shaped, W-shaped, X-shaped, star-shaped and others). On ships, vertical engines are most widely used, engines with cylinders located at a certain angle are less commonly used, and, as an exception, horizontal engines are found.
By the value of the average piston speed st engines according to GOST 4393-74 are conditionally divided into low-speed (with average speed piston up to 6.5 m/s) and high-speed (with a piston speed of 6.5 m/s and higher).
According to the frequency of rotation of the crankshaft engines are divided into low-speed (up to 250 rpm), medium-speed (250-600 rpm), high-speed (600-1000 rpm) and high-speed (more than 1000 rpm).
By appointment ship engines are divided into main - driving the propeller or main electric generators (during electric propulsion) and auxiliary - driving auxiliary mechanisms (generators, compressors, fire pumps, etc.).
All engines, including marine engines, according to GOST 4393-74, have a unified marking system using numbers and letters that determine the main design features of this type of engine. The letters indicate: H - four-stroke; D - two-stroke; DD - two-stroke double action; R - reversible; C—ship with a reversible clutch; П - with reduction gear; K - crosshead; N - supercharged. If the brand does not contain the letters P, K or H, then this indicates that the engine is non-reversible, trunk and naturally aspirated. The numbers in front of the brand indicate the number of engine cylinders, and the fraction after the letters indicates the cylinder diameter (numerator) and piston stroke (denominator) in cm.
So, for example, the engine brand 5DKRN 50/110 means that the engine is five-cylinder, two-stroke, crosshead, reversible supercharged, cylinder diameter is 50 cm, piston stroke is 110 cm.
Foreign-built engines do not have such a clear marking, since each company has its own designation system.
