Bosch has revealed new technology which dramatically cuts the levels of NOx emissions in diesel cars in the real world using already existing components.
The VW Dieselgate shenanigans of a 2015 haven’t just cost VW a great deal to ‘fix’, they are also costing the car industry as a whole a great deal as car buyers finally realise that emissions from diesel engines can be significantly more than emissions testing suggest, with real world emissions up to 40 times test results.
With so many car makers relying on diesels for sales – and none more than premium car makers like BMW and Jaguar – the cliff fall in demand for diesel cars in the wake of dieselgate is causing big problems. But Bosch say they have a solution.
Paradoxically, it was Bosch who produced the software which allowed Volkswagen to scam their diesel emissions (whilst warning VW it was not legal for production cars), but the new Bosch system is said to reduce levels of NOx way below not just current regulated levels but future ones too, and does so using components already available – and legally.
The problem with NOx emissions reduction in car exhaust gasses is that it only really works if gas temperatures are above 200C, and Bosch say their new thermal management system ensure this is achieved almost all the time, so the levels of NOx are dramatically cut whether the car is being driven in urban areas or on motorways, and whether you poodle along or drive like a loon.
It’s all very clever, and could be the ‘saving’ of diesel for passenger cars, but we do wonder if this could all have been done long ago if car makers’ obsession was not with CO2, but with the properly nasty stuff coming out of the tail pipe?
