Diesel fuel injection systems According to Bosch, in 2003 nearly 44% of the new cars sold in Western Europe were diesels. In 2005, the market share for Diesel engines is estimated at 50% of the new cars.
If the turbocharged diesel engine is the favorite of more and more Europeans, it is mainly due to the remarkable and amazing recent developments of the fuel injection equipments. Some types can generate an injection pressure exceeding the water pressure at a depth of 20'000 meters, much deeper than the Mariana Trench - which is the world's deepest ocean bottom at 11'035 m. The common rail injectors and electronic control systems of the latest generation are also able to perform up to 5 separate injections per cycle, with timing intervals of 4/10'000th of a second.
Ever since the arrival of electronic regulation and direct injection on small automotive diesels, we have shifted from several decades of apparent stagnation to a surge of enhancements. However the development of diesel fuel injection equipments is far from being over because it is essential to reduce even more the toxic exhaust emissions of the diesel engines.
