German auto supplier Bosch has announced a "breakthrough" in reduced diesel emissions using existing technology.
The technology, yet to be named, comprises of a new air management system that optimizes exhaust gas recirculation, resulting in improved airflow management, maintaining EGR temperatures above 200 degrees Celsius.
"There's a future for diesel," said Bosch CEO Volkmar Denner at its annual company conference this month. "Bosch is pushing the boundaries of what is technically feasible. Equipped with the latest Bosch technology, diesel vehicles will be classed as low-emission vehicles and yet remain affordable."
At the moment, European emissions rules limit diesel emissions to 168 milligrams per kilometer, versus Bosch's new claims of 40 milligrams for city driving and 13 milligrams per kilometer in combined driving. This breakthrough translates to a 90-percent improvement in Europe's emissions benchmarks.
This discovery should continue to push Europe towards reduced emissions.
In the past, European governments have subsidized diesel sales, citing superiority over gasoline with reduced CO2 emissions. More recently, diesel vehicle sales have plummeted amidst the emissions scandal, crushed used car values, and new clean air rules, with Volkswagen announcing a buyback program this month in German cities where diesel is no longer allowed.
No word yet from other partner automakers if they plan on testing Bosch's new technology.
