Note the table on page 11. Tier II bin 9 is listed as being equivalent to California LEV I. The NOx limit for these standards is 0.2 grams per mile. Actual test emissions for the ALH engine are about 0.5 grams per mile (versus the 1.0 gram per mile limit for Tier I diesel cars). Since in California LEV I becomes mandatory in 2004, the ALH engine needs to be replaced before then if VW is to sell TDI engines in California. Theoretically, the new 100hp pump injector engine which supposedly meets Tier II bin 9 will meet California LEV I as well.
Note also that Tier II bins 9 and 10 will be deleted after 2006. Also, California cars must meet LEV II after 2006. So meeting Tier II bin 9 / California LEV I won't be enough after 2006. Fortunately, 15ppm diesel fuel becomes universal in the US at that time. Will that be enough to allow car diesel engines to limit NOx emissions to 0.05 grams per mile (Tier II bin 5 / California LEV II)?
