The BMW B58 is a turbocharged direct injection straight-6 DOHC engine which began production in 2015.[1] It was launched in the F30 340i.[2] It is also part of BMW's new modular engine family, which is based on each cylinder comprising 500cc.[3] Similar with its N55 predecessor, the B58 also features a single twin-scroll turbo, direct fuel injection, Dual Vanos and Valvetronic .
Design
As the sucessor of the BMW N55 engine, the B58 also displaces 3.0 liter (which is technically a tad bigger, at 2.998L compared to 2.979L on the N55). It is also a bit bigger in its turbocharger with a 6 percent increase in turbine wheel size and 10 percent increase in compressor wheel diameter, resulting in a 20% increase in boost pressure. More so than in the N55, the B58 engine uses a water-to-air intercooler integrated into the intake plenum, thus reducing the charged air volume between the compressor and the intake. This increases performance by maintaining more even temperatures inside the intake. BMW has also incorporated an engine-mounted encapsulation system, which allows the engine to retain much of its heat for up to 36 hours which helps to reduce emissions and wear and tear during start-up, especially in colder climates.[4] As a part of BMW's new modular engine family, the crankcase is a completely new design engineered as both a gasoline and diesel engine in one common part. The closed deck crankcase is equipped with a completely new structure which can be identified by a complex array of ribs on the exhaust and intake side and an additional reinforcement frame on the oil sump side.[5]
