(autoinsidernews) - Yesterday at the Washington Auto Show, Volkswagen officially unveiled its cleanest diesel ever, which will be found in the next Jetta TDI. As we told you about earlier this month, the new diesel Jetta is powered the 2.0L BLUETEC diesel four-cylinder, which will meet emissions standards in all 50 states without the use of urea injection.
Instead, the new TDI uses a nitrogen oxide storage catalyst, which reduces NOx emissions by up to 90 percent. The engine management system in the Jetta changes operating modes periodically to treat the NOx that has been stored in the catalytic converter. A particulate filter in the exhaust system further reduces emissions, reports Trend.
Volkswagen didn't release any detailed information like power, pricing or fuel economy numbers. But the new clean diesel Jetta will be available in the U.S. market in the spring of 2008.
