Bosch comes up with a new solution to reduce harmful diesel emissionsDecember 4, 2019
While the automotive industry is looking for alternative environmental sources of energy for the operation of powertrains, in everyday life, especially when it comes to “heavy” technology, the good old diesel engine is still indispensable.
Every year, equipment manufacturers begin to produce machines with lower levels of harmful emissions. This is not only about all the familiar carbon dioxide (CO2), but also in the case of diesel engines, also about nitrogen oxides (NOx).
The current Euro 6 environmental standard sets 80 g per km as the maximum permissible NOx emission standard. As for commercial diesel automobile transport, the only method to achieve such indicators is to use gas-treated cleaning systems. This step makes it possible to reduce nitrogen oxide emissions by 90 – 95%.
The operation of such a system can be illustrated by the example of Denoxtronic – a system that Bosch has created and produces. It works as follows: a special measuring module receives information from the power unit control unit (such as speed and operating temperature). On their basis, a specific amount of a special reagent is introduced into the exhaust gas stream (this is nothing like a hydrogen solution of urea or urea). As a result, ammonia is formed, which reacts with nitrogen oxides and converts them into harmless nitrogen and water vapor.
From 2004, when the first Bosch Denoxotronic generation was shown, and until the middle of last year, the number of trucks with this system exceeded 10 million.
Bosch predicts that in 2030, approximately 75% of new passenger cars and light trucks will still have ICEs. For this reason, work on the modernization of gasoline and diesel engines should continue.
In addition, it was previously noted that Bosch microchips will increase the range of electric vehicles. Production of these microchips will begin next year.
