Diesel vehicle are receiving a lot of renewed interest in the U.S., and Isuzu's new diesel engine website is one more example of that. The site was launched to keep customers abreast of the new 2007 diesel emissions standards and, obviously, to promote Isuzu's diesel lineup. The site explains the features of Isuzu's 6H (7.8L) and the 4H (5.2L) engines and compares them to others. The company also enhanced its commercial vehicle website. The new diesel standards mean nitrogen oxide (NOx), hydrocarbons (HC) and particulate matter (PM) emissions must be 90 percent lower than the currently in effect 2004 standards. While some automakers have been forced to cancel their 2007 diesel vehicles in the U.S., Isuzu says it can meet the emissions standards because the low-emission technology has been in use in Isuzu trucks in Japan for the last two years.
