The new Cat® 349E hydraulic excavator features a 396 hp Cat C13 ACERT™ engine that meets U.S. EPA Tier 4 Interim emissions standards. The new 349E delivers more engine and hydraulic horsepower than its 345D predecessor while consistently averaging 5% improved fuel efficiency in typical applications. The 349E's Cat C13 engine operates either on ultra-low-sulfur diesel fuel (ULSD) or a blend of up to 20% biodiesel (meeting ASTM 6751 or EN 14214). The 349E's hydraulic system also contributes to fuel economy. An electric boom regeneration valve captures and recycles hydraulic energy when the boom lowers. In like manner, a new regeneration valve in the digging-arm circuit recycles oil between the cylinder ends during low-load, arm-in operation, reducing the volume of oil the hydraulic pump must produce and thus conserving fuel. A selection of booms and digging arms allows tailoring the 349E to its application. Each boom and digging arm uses castings and forgings in high-stress areas. Buckets feature new geometry with the leading edge pushed forward, resulting in more efficient filling, higher production, and greater operator control. Buckets also feature improved wear resistance for corners and side cutters. Access to routine maintenance items is improved with wider service doors (with redesigned hinges and latches) and a new two-piece hood. The water separator, with a water level sensor, includes the primary filter and is located in the side compartment at ground level. An electric priming pump is mounted on the primary filter base for easy access, and a new remote drain for the fuel tank is located in the side compartment. Relocating the oil check gauge and the engine oil filter further speeds routine service, and a new oil drain minimizes accidental spills. In addition, optional Fast-Fill and Quick Evac systems are available for engine oil and hydraulic oil.
