The EC140E excavator from Volvo Construction Equipment has a Tier 4 Final Volvo D4 engine, with a 5 percent increase in engine power and 10 percent improvement in fuel efficiency versus previous models. The hydraulics system, electronic control system and advanced ECO mode have been optimized to match engine power and reduce power losses. The redesigned main control valve and new software builds on the hydraulic control system, improving fuel efficiency and controllability. A boom float function allows pump power for boom lowering to be transferred to other functions, while the auto engine shutdown feature further helps to reduce fuel consumption by automatically switching off the engine after a preset amount of time. 828/650-2000; www.volvo.com/constructionequipment.
