Caterpillar officials announced the company's new
medium-duty C7 diesel engine has been certified by the Environmental Protection
Agency as compliant with the more stringent 2007 emission standards.
In a press release, Caterpillar stated the C7 reduces
pollution through a combination of precision combustion, advanced electronics
and after-treatment technology.
Several weeks ago, Volvo announced that three of its new heavy-duty
truck engines had earned EPA certification.
