Review and Assessment of Reduced Emissions/Clean Burning Diesel Engines for Integration into the Army Inventory.

摘要

This effort examines the availability of diesel engines having reduced emission/clean burning characteristics for potential trial in 4000 lb. capacity forklift trucks to be used in closed and semi-closed environments. The effort includes identification of substances which have been identified in diesel engine exhausts, health and safety considerations relating to those substances as established or recommended by U.S. and foreign governmental and professional agencies, and ranges of concentration of the substances which have been noted. Twenty-nine diesel engines which might be suited for use in 4000 (and 6000) lb. forklift trucks are characterized by manufacture-provided descriptive information and test data. A ranking scheme based on exhaust emissions and other parameters over a standardized work cycle was developed and applied to identify the candidate engines which appear most promising for the Army's application and, thereby, most appropriate for further testing. Analysis of the data did not identify a candidate engine suitable for use in a closed environment without precautions or limitations for human exposure. These questions are to be subjects of further analysis and empirical testing.
