Advanced diesel technology to meet multi-dimensional challenges of the diesel engine
The modern Common-Rail Diesel engine is no more a European phenomena while the long-term prognosis shows growth of about 9% in India and China. In India the Diesel engine has already a high share in the market due to the need of low operating cost while in China there is not only an ever increasing demand for light commercial vehicles but also for Passenger Cars. These two markets need robust and cost attractive Diesel Injection Systems, which must also be capable to fulfill the new emission norms like BS5 (Bharath Stage 5) or CN5 (China 5), while facing challenging environmental conditions, fuel quality and OEM requirements different to Europe. On the other hand the requirements for the European High-End Segment are not only to consume less fuel with the same power output – but to have the same noise and comfort level like a comparable DI-Gasoline-engine. Key enablers are a multiple injection capability with very short hydraulic dwell times combined with excellent mixture formation and more system injection pressure of up to 3000bar to achieve power output targets above 100 kW/l. Based on broad system competences in terms of Diesel combustion and control, Bosch offers tailored solutions for all segments and markets and adopts a modular approach, which actively builds upon the achieved maturity of functional groups and concepts. The resulting portfolio of Solenoid injectors and Piezo injectors are presented herein.
