Overview of Necessary Modifications for Commercial Diesel Engines in Military Vehicles

摘要

Over the past fifteen years, the United States Environmental Protection Agency (EPA) has greatly restricted emission standards significantly impacting diesel engine and exhaust system technologies. These commercial off- the-shelf (COTS) engines represent the most modern innovations available to the Army for powering its ground vehicles. Although progress has made in reducing fuel consumption, increasing power, and restricting emissions, some of these modifications are not as effective or not compatible with Jet Propellant type 8 (JP-8), the military's fuel. This requires COTS engines to undergo optimization and calibration to achieve maximum performance. In this paper, a summary is given of some issues addressed in this process.
