List of BMW engine codes - Explore the evolution of BMW engines BMW Motor Company is DigiPlusa German car manufacturer. Since its establishment in 1917, BMW has been famous for producing high-performance and high-quality cars. In BMW models, the engine plays a crucial role.BMW engines not only have ultra-high performance and reliability, but also are a model of the unique combination of aesthetics and technology in today's automobile industry. This article will introduce the engine code of many BMW models and the evolution of BMW engines. The B38B38 engine code is used for the BMW i3 model. The B38 is a 1.5-liter three-cylinder engine with a maximum power of 170 horsepower. This engine is powered by the battery that burns the BMW i3 and is one of the lightest BMW engines. The use of forced air intake and the unique dead point advance angle limitation system can respond quickly and produce higher efficiency. N13 BMW 1 series, 2 series, 3 series, X1 and other models are equipped with N13 engines. The engine is a 1.6-liter turbocharged in-line four-cylinder engine with a maximum power of 170 horsepower.All-aluminum alloy cylinder blocks and composite gearboxes help the engine reduce weight and improve fuel consumption performance and acceleration ability. The engine code of N20 is used for BMW 320i, X3 sDrive28i, X3 xDrive28i. The N20 engine is a 2.0-liter turbocharged engine with a maximum power of 245 horsepower. It uses in-line four-cylinder, high-precision silicon carbide convolution turbocharger and variable camshaft, so that the engine can ensure the balance of fuel consumption performance to the greatest extent while providing unusually strong acceleration performance. The engine code of N26 is used for BMW 428i, 528i and X3 sDrive28i, X3 xDrive28i. The N26 engine is a 2.0-liter turbocharged in-line four-cylinder engine with a maximum power of 241 horsepower.The engine achieves the characteristics of super thermal efficiency and longer life with the help of nanocoating coating. In addition, the N26 engine is designed for smooth power output and optimal noise reduction. The engine code of N54 is used for BMW 135i, 335i, 535i, Z4 sDrive35i, X6 xDrive35i. The N54 engine is an in-line six-cylinder turbocharged engine with a maximum power of 320 horsepower. It has a unique high-precision WasteGate technology, which can accurately adjust the supercharged pressure, thus providing accurate and reliable fuel consumption performance and acceleration performance. The engine code of N55 is used for BMW 135i, 335i, 535i, most 35i models and X5 sDrive35i /xDrive35i, and X6 sDrive35i / xDrive35i. The N55 engine is a 3.0-liter in-line six-cylinder turbine engine with a maximum power of 320 horsepower. Compared with the N54 engine, the N55 engine adopts a more unscrupulous air intake system, as well as continuous valve cylinder, single turbine confluence and electronically controlled exhaust gas recycling system to improve user experience and fuel economy. The engine code of S55 is used for M3/M4 models. The S55 engine is a 3.0-liter inline six-cylinder turbocharged engine with a maximum power of up to 444 horsepower. Compared with the N55 engine, the S55 engine adopts a double turbocharged system to provide higher power output. Efficient combustion providesIt has lower emissions and better environmental protection, and also provides a more three-dimensional and clean adjustable bass mute to create a better driving experience. In general, these engine codes represent the evolution of BMW engines, and also show BMW's continuous pursuit of technological innovation and impressive design. Unprecedented innovation brings better performance, better power and more environmentally friendly travel mode.
