The engine is equipped with a new close-coupled catalytic converter system, which helps to reduce emissions and provide more customer value. The system consists of two 102-cubic-inch (1.7 liters of volume per bank) converters, placed five inches from the exhaust manifold, and a close-coupled Y-pipe. The converters are bolted (rather than welded) to the exhaust manifold flange. They have a standard construction, consisting of a ceramic substrate, insulating blanket material and a steel shell. The new architecture replaces two previous mid-coupled converters.
The engine meets Federal emissions requirements and California Low Emissions Vehicle (LEV I). It also meets near-zero evaporative emissions standards in all states. |
