The N55B30 is a 3.0L inline-six turbocharged engine introduced by BMW in 2009 to fully replace the twin-turbo N54. It was the first to combine a single-turbo twin-scroll turbocharger, Valvetronic electronic valve control, and high-pressure direct injection technology, significantly improving fuel economy and reliability while maintaining excellent power output.
Core Materials and Structural Design (Closed-Deck Aluminum Block):
High-Strength Aluminum Alloy Casing: The main body of the cylinder block is cast from high-strength aluminum alloy, significantly reducing the load on the vehicle’s front axle.
Closed-Deck Design: Unlike the Open-Deck design of the previous-generation N54, the N55 employs a closed-deck cylinder block structure. This design greatly enhances the rigidity and resistance to deformation of the upper cylinder section, enabling it to withstand high combustion pressures and prolonged operation under heavy loads.
Cast-Iron Sleeves: Highly wear-resistant cast-iron sleeves are press-fitted into the inner walls of the cylinders, ensuring excellent wear resistance and exceptional suitability for remanufacturing.
Our products are exported to various parts of the country, and the customers we have worked with have received unanimous praise. The company has invested over 20 million yuan in high-end remanufacturing equipment imported from abroad and a first-class production team in the country. Our warehouse has a total area of over 8000 square meters, with scientific management and sufficient supply of goods.
