B58 Engine,1 Introduction, This training manual describes the special characteristics of the B58 engine in the B58B30M0. variant It also describes and illustrates differences to the N55 engine in the N55B30M0 variant The. document also describes the common factors of the current B38 installed in the I12 and future B48. and B57 engines The US market will receive the B58B30M0 ULEV II and B56B30M0 SULEV variants. The most important development characteristics relate to BMW EfficientDynamics and its modular. kit strategy Using uniform processes means that development and manufacturing costs can be. lowered In production the complexity of the manufacturing process planning and implementation is. reduced In Service the warehousing is simplified as a result of the reduction of part variety and the. safe handling of products is increased,1 1 Model overview. The following table provides an overview of the BMW models in which the new engine will be used. from mid July 2015, Model Version Series Displacement Power in Torque in.

F34 5200 6500 1380,1 2 Modular design, The B58 6 cylinder engine forms part of the new in line engine family The B58 engine features. elements including double VANOS TwinPower exhaust turbocharger technology indirect charge air. cooling that has been integrated into the intake system and a heat management module. The EfficientDynamics strategy of the N engine generation has resulted in a large number of different. technologies finding their way into the BMW engine world The strategy for the simplification of. inspection work is also pursued with the B engine generation. The new engine generation is mainly characterized by lower fuel consumption and fewer exhaust. emissions It complies with Euro 6 in ECE and ULEV II in the US A characteristic map controlled. oil pump an injection system with direct rail and electric arc wire injection cylinder bores are used. to achieve low fuel consumption All engines are also equipped with an automatic engine start stop. function and intelligent generator control as a further EfficientDynamics measure. Compared with the N engines the new B engine generation demonstrates a considerably higher. number of common and interchangeable parts with the Bx7 diesel engines and the Bx8 gasoline. B58 Engine,1 Introduction, BMW EfficientDynamics strategy of the Bx8 engine generation. Description Explanation, BMW EfficientDynamics BMW EfficientDynamics strategy.
More performance More performance,Less fuel consumption Less fuel consumption. Fewer CO2 emissions Less carbon dioxide emissions, BMW EfficientDynamics also stands for more power less consumption and less carbon dioxide. emissions in the new engine generation With the additional modular strategy other objectives such. as lower costs greater production flexibility as well as enhanced customer satisfaction are now also. being pursued,B58 Engine,1 Introduction,Modular strategy of Bx8 engine generation. Description Explanation,Modular Modular strategy, Enhanced customer satisfaction Enhanced customer satisfaction. Greater flexibility Greater flexibility,Less costs Less costs.
The modular strategy aims for different effects throughout the product development process and. product life cycle For instance using uniform processes means that development and manufacturing. costs can be lowered In production the complexity of the manufacturing process planning and. implementation is reduced In Service the warehousing is simplified as a result of the reduction of part. variety and the safe handling of products is increased.
