Dozers Display Diesel Improvements - Tier 4-1 compliant mid-size dozers offer more than clean air as manufacturers upgrade performance

摘要

As crawler dozer manufacturers sweep the eraser crumbs off their drawing boards again to tailor their mid-size-model designs to meet EPA's Tier 4-1 emissions mandates, they are taking the opportunity to build in additional efficiency. Good air, good productivity, good business. The EPA says that when the country's entire inventory of older off-road engines has been replaced with Tier 4-compliant machines (by 2030), the country will enjoy an annual reduction of more than 738,000 tons of NO_x and 129.000 tons of particulate matter.
