THE EFFECTS OF TIER 4 EMISSION STANDARDS ON THE WATERJET INDUSTRY

摘要

This paper documents the impact of Tier 4 final engines on the water jetting industry. Diesel engines, which have been the most common means of providing power for portable water jetting pumps , have been subject to the EPA's tightening standards for the emission of harmful exhaust gases. The final stage of the reduction process is now at a point that both the manufacturers and users of water jetting pumps are learning what it is like to operate these new diesel engines. While the cost to procure a Tier 4 Final engine is typically greater than that of a Tier 3 or Tier 4i, the cost savings during the life of the engine can be significant. In addition they greatly reduce harmful exhaust gases like nitrogen oxides, carbon dioxide and carbon monoxide. Owning a Tier 4 Final engine also ensures that owners/operators will be able to take their diesel powered pump anywhere in the U.S. and operate it in the future.
