Bosch Common Rail System for Small Diesel Engines in Emerging Markets

摘要

Before the actual economic slowdown hit the globe, there were symptoms of stagnation in the developed markets, whereas the emerging markets were showing higher growth rates in the economy. Despite these retarders, India in particular is showing signs of becoming a potential global hub for small car. The per capita income in India is about $1000 whereas the per capita in Germany is about ～ $38,000. This translates into a very small population of Indian consumers who will be able to afford products currently marketed in Western Europe & the US. The challenge for the Auto OEMs and also to the suppliers is to offer unique products at dramatically lower costs to match the special needs and lower purchasing power of most emerging market buyers. One such outcomes of such an innovative model have been the "Tata Nano" unveiled at the Auto Expo India 2008. Developing and creating low-cost products is not equal to low-tech products. It is about having a holistic approach with local development adapted with local manufacturing having clear price-performance targets. These ultra low cost automobiles target the huge consumer base in the emerging markets that drives two-wheelers today (7 million new 2 wheelers every year in India alone). Come 2010, in major Indian cities, automobiles in India have to comply with BS4 emission norms (equivalent of Euro 4). Bosch has conceptualized under these boundary conditions a Common-Rail-System for small diesel engines that gives Auto OEMs a state-of-the-art technology necessary to meet the future emission legislations and also a "value for money" robust system designed to operate in the ultra competitive emerging market situation. In this paper, we shall discuss about the adoption of modern common rail technology to suit to this new segment of ultra low cost automobiles and the requirements for a FIE systems that full fills these severe boundary conditions. Furthermore the outlook shows the future potential of this system.
