The B38 BMW Turbocharger is an important component of the BMW B38 engine, which is a 1.2 - liter and 1.5 - liter turbocharged straight - three DOHC petrol engine that entered production in 2013, replacing the BMW N13 straight - four engine. Here is an introduction to the B38 BMW Turbocharger:
Basic Information: The B38 engine series uses a single - scroll turbocharger. It features direct injection, an 11:1 compression ratio, variable valve timing (Double - VANOS), and the world's first aluminum turbine housing, which is manufactured by Continental. This turbocharger is designed to provide forced induction to the engine, improving its power output and efficiency.
Performance Characteristics: The low - inertia turbocharger of the B38 engine enables the engine to reach its maximum torque from 1250 rpm and maintain it until 4500 rpm. For the 1.5 - liter version, the maximum torque can reach 220 N·m, and for the high - performance B38K15T0 model, the maximum torque can reach 320 N·m. This allows the engine to output powerful and continuous power in the low - and medium - speed ranges, enhancing the vehicle's acceleration performance and driving experience.
Technical Features: In the B38K15T0 engine, which is an upgraded version of the B38, the exhaust valve stem diameter is increased to prevent valve vibration caused by high - pressure boost. The turbocharger's turbine housing is integrated in a steel manifold, and the boost pressure is controlled at 1.5 bar through an electric waste - gate valve. These technical improvements ensure the engine's performance while also taking into account high efficiency and stability.
Vehicle Applications: The B38 engine, equipped with this turbocharger, is used in a variety of BMW models, including front - wheel - drive cars such as the Mini Hatch and BMW 2 Series Active Tourer, as well as in BMW's traditional rear - wheel - drive and all - wheel - drive (xDrive) configurations. The first car to use the B38 engine is the BMW i8 hybrid sports coupé, where it is used as a transverse mid - mounted engine.
