Caterpillar Inc. Receives United States Environmental Protection
Agency’s Clean Air Excellence Award
The Caterpillar D7E electric drive track-type tractor is recognized for its emission reductions, efficiency gains and overall innovative technology
PEORIA, Ill.—Caterpillar Inc. has been awarded the Environmental Protection Agency (EPA) Clean Air Excellence Award for its D7E track-type tractor with electric drive. The electric drive system is the first of its kind in this application, designed to maximize efficiency and productivity while conserving natural resources. The diesel-electric drive technology uses a diesel engine to drive an electric generator that powers two AC electric drive motors. The D7E track-type tractor (bulldozer) increases dozing efficiency by 25%, reduces fuel consumption by 10 to 30%, and reduces greenhouse gas emissions. The total emissions reductions from productivity increase and fuel savings, per hour, are: 10 % for CO,
20 % for NOx and HC, 51 % for PM, and 23 % for CO2.
