"We have the best diesel engines and we do not give them up"-BMW

During the Paris Motor Show, BMW's managing director for Development, Klaus Fröhlich, said his brand "has the best turbodiesel engines on the market and will therefore continue to focus on diesel engines for the future ". This is at a time when manufacturers everywhere are announcing that they are finished with the development of new diesel engines, while others stop selling this type of motorization in some models and even in certain markets.Fröhlich went so far as to declare that he has not yet decided to "withdraw the diesel engine from the American range of the new X5," in a market where his closest opponents quickly switched diesel engines to hybrids and gasoline plug-in hybrids. However, the BMW technician is aware of the difficulties created by the most stringent anti-pollution standards, which have led to the suspension of a practical or technical terms, if you prefer, there is no reason to suspend the production of diesel engines, current regulations while continuing to manufacture their gasoline relatives. It is good to keep in mind that without a particulate filter, assuming that both are using the turbocharger, they all largely exceed the maximum limits of "fumes" emitted to the atmosphere. And if some are more visible than others, they are no less polluting. Series of gasoline engines, starting with the mighty M3.
In practical or technical terms, if you prefer, there is no reason to stop the production of diesel engines, provided they are in line with the current regulations, while continuing to manufacture your gasoline relatives. It is good to keep in mind that without a particulate filter, assuming that both are using the turbocharger, they all largely exceed the maximum limits of "fumes" emitted to the atmosphere. And if some are more visible than others, they are no less polluting.Continuing the petrol / diesel comparison, it should also be borne in mind that, without three-way catalysts, gasoline units would be a disaster in emissions of CO (carbon monoxide), HC (hydrocarbons) and NOx (nitrogen oxides) because is precisely to nullify these three elements that exist, transforming them into CO2 (carbon dioxide), water, nitrogen and hydrogen. Diesel, for its part, requires the same technological support to "calm down" the pollutants, but always used only two-way catalysts (CO and HC) and only three years ago began to benefit from the third route to cancel NOx, by injection of AdBlue into a selective catalyst.Equally, therefore, diesel and petrol engines are equivalent to particulates, HC and NOx, but diesel engines, because they consume less fuel in absolute terms, release less CO2, which gives them a carbon dioxide is not polluting, it is responsible for equally severe global warming. It is precisely because of this that Fröhlich is betting on BMW diesel. However, it is neglecting the reasons that led its competitors to abandon their diesel engines: the political persecution that this type of mechanics has been and continues to be targeted, which has nothing technical or rational.
