There are lots of advantages of SCR systems in for potential customers purchasing diesel engines. Second, they dramatically reduce toxic oxides of nitrogen (NOx), which help to meet stringent environmental standards for vehicles at the same time as making air more cleaner. Thirdly, the SiC system can raise fuel efficiency by as much as 5%, so overall emissions fall and - with less heat loss to consider when weighing up designs is necessary in order to obtain optimal combustion conditions close under those found one cylinder wall Comprehensive engine redesign not needed. Fourthly, they are easy to maintain and have long lives.A yield of these advantages can be expected to be a kind of fertile bearing. Fifth, SCR is a solid, proven technology that serves a range of industries both inside and outside China; meaning easy, worry-free operation for all drivers fitted with it.
