Lowering Emissions in 2011

摘要

Heavy engines and oversized loads, take an environmental toll, but until recently engine and fuel technology didn't offer many solutions to reduce emissions without drastically cutting performance. Fortunately, in 2011 two technologies are changing the way heavy fleets use fuel. Emissions standards are tightening in the United States, with Canadian regulations not far behind. Selective Catalytic Reduction (SCR) engines and Compressed Natural Gas (CNG) engines, which allow certain fleet applications to meet the new standards without performance concerns, are thus gaining in popularity, especially among waste haulers, manufacturers, government and municipal contractors and heavy duty fleets.
