This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of engine emissions control by modifying intake combustion gas composition from that of ambient air using gas separation membranes has been developed during several programs undertaken at Argonne. These have led to the current program which is targeted at heavy-duty diesel truck engines. The specific objective is reduction of NO(subscript x) emissions by the target engine to meet anticipated 2007 standards while extracting a maximum of 5 percent power loss and allowing implementation within commercial constraints of size, weight, and cost. This report includes a brief review of related past programs, describes work completed to date during the current program, and presents interim conclusions. Following a work schedule adjustment in August 2002 to accommodate problems in module procurement and data analysis, activities are now on schedule and planned work is expected to be completed in September, 2004. Currently, we believe that the stated program requirements for the target engine can be met, based upon extrapolation of the work completed. Planned project work is designed to experimentally confirm these projections and result in a specification for a module package that will meet program objectives.

This book was released on 2019 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study aims to investigate the potential improvement of energy efficiency and emission performance for a ground transportation system equipped with connected and automated vehicles (CAV) by means of intelligent and coordinated control design from vehicle powertrain and aftertreatment perspectives. First, a dedicated control algorithm is designed for heavy-duty vehicle exhaust emission aftertreatment system against unknown catalyst aging condition. To reduce the tailpipe NO[subscript x] emissions, urea-based selective catalytic reduction (SCR) systems, which utilize ammonia as the reducing agent for deNO[subscript x] reactions, have become indispensable for Diesel engine powertrains in ground vehicles. A closed-loop cost-friendly SCR controller is designed for the implementation purpose. Second, predictive control methods for vehicle powertrain and aftertreatment systems utilizing information induced by road environment perception and connectivity of vehicles are proposed. Simulation results indicate the overall emission performance as well as energy efficiency can be improved with a proper synthesis of preview information and coordinated control design. Third, the impacts of human driver behaviors variation on vehicle fleet energy consumption and travel time are evaluated providing insights on future CAV control design for efficiency improvement. Through a proper integration of these three interconnected aspects, an energy-efficient mobility for future transportation system is envisioned

This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subcontractor report details results of on-road development and emissions characteristics of C-Gas Plus natural gas engine in Viking Freight heavy duty trucks. The objective of this project was to develop, on road and in service, a natural gas truck/bus engine (the C-Gas Plus) with higher horsepower, lower cost, and better performance and diagnostics than the previous C8.3G natural gas engine. The engine was to have an advanced engine management control system to enable implementation of proven technologies that improve engine performance and power density (hp/L). The C-Gas Plus engine was designed to meet the following objectives: (1) Higher engine ratings (280 hp and 850 ft-lb torque for the C-Gas Plus) than the C8.3G natural gas engine; (2) Lower capital cost than the C8.3G engine; and (3) Low emission standards: California Air Resources Board (CARB) low-NO(subscript x) (oxides of nitrogen) (2.0 g/bhp-h) and U.S. Environmental Protection Agency (EPA) Clean Fuel Fleet Program ultra-low emission vehicle (ULEV) emission certifications.

This book was released on 2018-09 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Revisions to In-Use Testing for Heavy-Duty Diesel Engines and Vehicles - Emissions Measurement and Instrumentation - Not-to-Exceed Emission Standards (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Revisions to In-Use Testing for Heavy-Duty Diesel Engines and Vehicles - Emissions Measurement and Instrumentation - Not-to-Exceed Emission Standards (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is taking direct final action on several revisions to EPA's mobile source emission programs standards and test procedures. EPA believes that each of these is minor and non-controversial in nature. Most of the changes arise from the results of the collaborative test program and related technical work we conducted for the highway heavy-duty diesel in-use testing program. Most noteworthy here is the adoption of a particulate matter measurement allowance for use with portable emission measurement systems. Related to this are two provisions to align the in-use program timing requirements with completion of the program as required in current regulations and the incorporation of revisions to a few technical requirements in the testing regulations based on information learned in this and one other test program. Finally, the DFR modifies a few transitional flexibilities for locomotive, recreational marine, and Tier 4 nonroad engines and incorporates a handful of minor corrections.

This book was released on 2018-08-20 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heavy-Duty Engine and Vehicle, and Nonroad Technical Amendments (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Heavy-Duty Engine and Vehicle, and Nonroad Technical Amendments (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA and NHTSA, on behalf of the Department of Transportation, are each adopting corrections to provisions in our respective Medium- and Heavy-Duty Greenhouse Gas Emissions and Fuel Efficiency final rule issued on September 15, 2011. These amendments eliminate duplicative reporting requirements, reduce inadvertent minor differences between the EPA and NHTSA programs regarding such matters as voluntary early model year compliance, better align testing procedures to market realities, and reduce unnecessary testing burdens. This action also separately amends several regulations exclusive to EPA by: adjusting the provisions of the replacement engine exemption, expanding EPA's discretion to allow greater flexibility under the Transition Program for Equipment Manufacturers related to the Tier 4 standards for nonroad diesel engines, specifying multiple versions of the applicable SAE standard for demonstrating that fuel lines for nonroad spark-ignition engines above 19 kilowatts meet permeation requirements, and allowing for the use of the ethanol-based test fuel specified by the California Air Resources Board for nonroad spark-ignition engines at or below 19 kilowatts. Some of the individual EPA-only provisions of this action may have minor impacts on the costs and emission reductions of the underlying regulatory programs amended in this action, though in most cases these are simple technical amendments. For those provisions that may have a minor impact on the costs or benefits of the amended regulatory program, any potential impacts would be small and we have not attempted to quantify the potential changes.

Download or read book Review of the U S Department of Energy s Heavy Vehicle Technologies Program written by National Research Council and published by National Academies Press. This book was released on 2000-11-01 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: As national priorities have been focused both on reducing fuel consumption and improving air quality, attention has increased on reducing emissions from many types of vehicles, including light-duty, medium-duty, and heavy-duty diesel-powered vehicles. Meeting the recently promulgated (and proposed) emission standards and simultaneously increasing fuel economy will pose especially difficult challenges for diesel-powered vehicles and will require the development of new emission-reduction technologies. In response to a request from the director of OHVT, the National Research Council formed the Committee on Review of DOE's Office of Heavy Vehicle Technologies to conduct a broad, independent review of its research and development (R&D) activities.
