Title: Evaluation of the feasibility, cost-effectiveness, and necessity of equipping small off-road diesel engines with advanced PM and/or NOX aftertreatment

Principal Investigator / Author(s): Durbin, Thomas

Contractor: UC Riverside

Contract Number: 14-300


Research Program Area: Emissions Monitoring & Control

Topic Areas: Mobile Sources & Fuels


Research Summary:

The objective of this study is to evaluate the potential effectiveness, feasibility, and cost effectiveness of implementing regulations on mobile off-road diesel engines with rated powers of less than 37 kW that will require the use of advanced emission control strategies, such as DPFs and SCR. This project will include a comprehensive review of available aftertreatment and other technologies, demonstrate selected aftertreatment technologies on actual engines and verify the emissions performance of these devices through a series of emissions and durability tests, evaluate the cost implications of the added emissions control strategies, evaluate the potential impacts of additional emissions controls on the emissions inventory, and evaluate the potential impact on the small engine marketplace and consumer choice in that area.
