Acura says it will introduce the new i-DTEC clean diesel engine to the North American market in 2009. The i-DTEC engine reduces noxious exhaust emissions while boosting power and fuel efficiency. A combination of optimized combustion chamber design and reduced injection time results in a clean, quiet engine that delivers excellent performance for an enjoyable driving experience. In addition, the i-DTEC engine meets the ultra-stringent U.S. EPA Tier II Bin 5 emission standards without the on-board storage of urea.
