Caterpillar’s hybrid is fuel savvy
Apr. 22, 2014 – Caterpillar has introduced the industry's first hydraulic hybrid excavator boasting that it can save up to 25% on fuel. The Cat 336E H sacrifices nothing in terms of power or production and is quiet too. The company also recently announced a new hybrid, the Cat 336F. Hydraulics provide superior power density, which is why Caterpillar selected a hydraulic solution for its hybrids. The Cat 336F H Hybrid will be powered by a U.S. EPA Tier 4 Final Cat C9.3 ACERT engine.
"The 336F H's Electronic Standardized Programmable (ESP) hydraulic pump saves significant fuel by integrating the machine's power sources and matching engine performance to the load encountered," the press release explains. "The unique Cat Adaptive Control System (ACS) valve optimizes hydraulic performance by intelligently managing restriction and flow, seamlessly controlling machine motion and ensuring that hydraulic power is available precisely where and when it is required."
The Cat 336E Hyprid has been in Canada for almost a year now and the Cat 336F will be available soon.
