Bosch, the world’s largest supplier of automotive components is celebrating the production of its 75 millionth common-rail system.
This technology, which was first used in cars 14 years ago, marked the start of a new image for diesel. In 1997, the share of diesel passenger cars sold in western Europe was 22 percent, whereas today every second newly registered passenger car is a diesel.
“In the past, diesel engines were seen as economical and robust. The modern common-rail diesel is just as efficient and durable, but it is also extremely dynamic, comfortable, and eco-friendly.” says Dr. Markus Heyn, executive vice president passenger cars in the Bosch Diesel Systems division.
The first customers for common-rail systems in 1997 were Alfa Romeo, for its 156 JTD model, and Mercedes, for the C220 CDI. Unit sales of common-rail systems grew rapidly in the following years.
By 2001, three million Bosch common-rail systems were in use, by 2002 the figure had already grown to ten million, and by the start of 2009 it was 50 million.
The name “common rail” is a reference to the pressure accumulator from which fuel is injected at high pressure into the cylinders via the injectors connected to it. The possibility of multiple injections that this allows makes engines quieter and reduces fuel consumption, as well as cutting emissions of CO2 and other pollutants.
