Note the code down. The code is made up of a string of letters and numbers that describe different features of your engine. The first two numbers in the example code, “39 8 D 1,” stand for displacement, “8” stands for the number of cylinders, “D” stands for idea, and “1” stands for differentiation concept. The concept code is broken down into the following codes, along with their definitions: “D” stands for diesel, “E” for fuel injection, “K” for catalytic converter, “S” for 4-valve technology, “T” for turbo, and “V” for carburetor.

Meanings of BMW Engine Codes and Their Location
Finding out what type of engine is in front of you and whose automobile it belongs to will be quicker and easier if you comprehend the logic behind the labels used on engines.
BMW engines are identified by a sequence of numbers and letters that correspond to the engine’s technical specifications. This set may appear to have no logic and that the numbers are random at first glance. Contrary to popular belief, the VIN Number (also known as the vehicle identification number) is used by manufacturers to identify the version of a vehicle it is.
The upper-left corner of the tables below shows an example of the engine code. The symbol whose meaning is clear from this table is marked in red.
Codes for BMW Engine Identification
All Americans are affected by this information. From 1978, BMW engines. On the engine block are codes that can be used to determine the engine’s displacement size, country version, fuel system, revision state, and serial number.
The engine block may have a variety of codes imprinted into it. These symbols stand for:
1. NUMBER AND CODE OF ENGINE:
Engine No. :
An eight-digit engine number, made up of two sets of four digits, will be assigned to a series production engine. Information on the assembly line and the serial number of the engines produced each day is contained in the first block’s first four digits. The factory code and manufacturing day are displayed in the second block.
An engine designation code is stamped in series manufacturing engines in addition to the eight-digit engine number for model identification. With the aid of Chart 1, these numerals can be decoded.
Note: The codes for new/remanufactured engines obtained from the parts department are different from those for production engines and should not be confused with them. This code (see list below) contains details on the nation version, change status, fuel system, and number of cylinders for engines fitted during production:
The information for the remanufactured engine is now die-stamped in the same location as for new engine identification after the digits for the original engine data were ground off.
Similar to engines in series production, the 8-digit engine number is made up of 2 blocks of 4 numbers, however they represent distinct information:
- Information on the daily production of engines is given in the first block of four digits.
- The month and year of production are also included in the second block, along with a code for either a new or remanufactured engine.

codes applied to engines in series production:
Chart 2 for engines of the U.S. version can be used to decode these figures. The engine’s precise part number is identified by this decoding.
Codes E

The BMW N53 was introduced in 2007, and this caused the N52 to start being phased out in European markets. However, because of the high quantities of sulfur in the gasoline, the N53 was ruled inappropriate in markets like those in the United States, Canada, Australia, and Malaysia. The BMW N20 turbocharged four-cylinder engine started to replace the N52 in 2011 and continued doing so until the N52’s manufacture ceased in 2015.

The arrangement of an engine’s cylinders determines how car engines are classified:
- Cylinders in straight engines are arranged in a single row that runs parallel to the vehicle. They are typically used for saloon-style vehicles.
- The most popular type is an inline engine, which is frequently utilized in compact family vehicles like hatchbacks. Similar to the straight kind, but at a right angle to the automobile, they feature a row of cylinders organized in the engine compartment, allowing parts like the radiator, battery, and cooling system to be easily fitted around the sides.
- When viewed from the front, the cylinders of an engine with a V configuration are positioned at an angle to one another. Supercars and other high-end vehicles are better off with this configuration.
- Cylinders are arranged horizontally in two lines, pointing outwards, in a flat engine architecture. Even though this type of engine is less frequently employed than other designs, sports cars can handle more comfortably thanks to its lower center of gravity.
Engines are further divided into three categories: GDI (Gasoline Direct Injection), MPI (Multi Point Injection), and CRDI based on the fuel injection technology.
- The most popular gasoline engine technology, GDI, raises the efficiency of gasoline engines by sprinkling fuel directly into the combustion chamber. This kind of technology is more powerful and fuel-efficient than other gasoline engines, but it is also more expensive and noisy and vibrational than those engines.
- In comparison to GDI, MPI is less powerful and fuel-efficient, but it also offers better longevity and less vibration and noise.
- Diesel engines use CRDI, which offers a high combustion rate, minimal emissions, and increased engine power.
