Mack Trucks, Inc. has announced that its 12-liter Mack E-Tech engine, which will meet the aggressive 2002 emissions requirements, is moving the industrial validation phase of development.

The company said the engine has so far met engineering development targets for emissions, which are 10% to 20% below the federal standards that will take effect in October 2002. The engine also manages to meet those required levels while maintaining a 460-horsepower rating.

Mack said that the cornerstone technology of its emissions-compliant engine is cooled exhaust gas re-circulation (EGR), which the company sees as the most viable technology for meeting the emissions standards for oxides of nitrogen (NOx) and particulates in the 2002 timeframe.

However, EGR will not be the sole technology Mack uses to satisfy the requirements. Mack engineers will use new technologies that will be progressively introduced in the E-Tech engine between now and 2002.

The company said that one key element of its strategy will be a significant evolution of the engine's unit pump fuel system, in which Mack will deploy flexible injection capabilities as early as the second half of 2001.
