Caterpillar: 349E hydraulic excavator

By |  February 12, 2013

Caterpillar’s 349E hydraulic excavator features a 396-net-hp Cat C13 engine that meets Tier 4 Interim emissions standards. The 349E delivers more engine and hydraulic horsepower than its 345D predecessor and averages 5 percent improved fuel efficiency in typical applications, according to Cat. The engine, which operates either on ultra-low-sulfur diesel fuel (ULSD) or a blend of ULSD and 20 percent biodiesel, uses the Cat Clean Emissions Module (CEM) to meet Tier 4 Interim standards. The CEM regeneration system is designed to be transparent to the operator and regenerate when the conditions are optimal with no operator intervention. In automatic mode, the regeneration system allows the machine to work as normal with no interruptions to the work cycle.
