Volkswagen AG says it will begin installing urea-based emission control systems in its diesel engines "as soon as possible" to meet nitrogen oxide (NOx) pollution standards.
So-called selective catalytic reduction (SCR) systems are already widely used by other diesel makers. The technology reduces NOx by injecting a urea-water solution, standardized in Europe as AdBlue, into the exhaust stream.
VW has been using less-expensive lean NOx traps but struggled with the technology to meet U.S. diesel emission limits. Last month the company admitted 11 million of its diesel vehicles are equipped with software that could be used to cheat emission tests in various markets.
