What is a remanufactured car engine?October 21, 2026
What is engine assembly?The BMW N55B30 is BMW’s iconic 3.0-liter inline-six turbocharged engine. As a groundbreaking successor to the twin-turbo N54, the N55’s cylinder head design integrates three of BMW’s
core technologies: the Valvetronic electronic valve lift system, Double-VANOS dual variable camshaft timing, and high-pressure direct injection into the cylinder.
Cylinder Head Material and Advanced Manufacturing Processes:
Material: High-strength, lightweight aluminum alloy high-pressure die-cast cylinder head (High-grade Aluminum Alloy Cylinder Head). Utilizing precision casting technology,
it withstands the intense forces generated by turbocharging while delivering exceptional heat dissipation efficiency and a lightweight design.
Internal Channels and Oil Circulation Design: The interior features an extremely precise integrated high-pressure oil circuit and a complex coolant jacket design
(specifically engineered for the Valvetronic camshaft servo drive and servo lubrication), along with highly wear-resistant alloy valve seat rings and valve guides, perfectly handling
the demanding operating conditions of high-frequency direct-injection turbocharging.
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.
