Download or read book PEMS Based In service Testing written by and published by . This book was released on 2015 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guidance document is a JRC technical support document, contributing to the development of best practices with PEMS. It shall be used primarily for the preparation, the execution and the follow-up of the emissions tests with PEMS on road heavy-duty vehicles (HDV) equipped with conventional combustion engines (gasoline, diesel, CNG, LPG). The document does not substitute either the operation manuals of the instruments or safety rules and recommendations nor official regulatory texts regarding in-use emissions tests with PEMS. The intention of this guide is to clarify some operational points of the PEMS procedure and to provide a guide for the application of PEMS inside and outside the regulatory context (In-Service Conformity Testing of heavy-duty engines as foreseen in Regulations 582/2011 and 64/2012).

Book excerpt: The Euro VI Regulation (EC) No 595/2009 and the implementing Regulation [2] (EC) 582/2011 introduces a procedure for PEMS testing as a mandatory part of the type approval legislation in order to check the conformity of heavy-duty engines with the applicable emissions certification standards during the normal life of those engines: this is the so-called "In Service Conformity" (ISC) requirements. In addition, Euro VI engines also have to verify their actual in-use emissions already at type approval (PEMS demonstration test). Even if the PEMS procedure has already been introduced into legislation there is still a need for further evaluation and development. Article 14(3) of the implementing regulation for Euro VI (EC) No 582/2011 states the following: "Any additional requirements with respect to off-cycle in-use vehicle testing referred to in point (d) of paragraph 1 shall be introduced after the assessment of the PEMS procedures set out in Annex II. The assessment shall be finalised by 31 December 2014." An assessment of the currently introduced PEMS procedure should therefore be carried out, and based on the outcome of this assessment; proposals for amending the PEMS procedure should be made. The European Commission through DG ENTR in co-operation with DG JRC launched in January 2012 a programme to address the legislative mandate to assess the present PEMS procedure. This report describes the activities during the programme, its findings and recommendations for amending the PEMS procedure.

Download or read book Future Powertrain Technologies written by Stephan Rinderknecht and published by MDPI. This book was released on 2020-12-17 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the various factors greatly influencing the development process of future powertrain technologies, the trends in climate change and digitalization are of huge public interest. To handle these trends, new disruptive technologies are integrated into the development process. They open up space for diverse research which is distributed over the entire vehicle design process. This book contains recent research articles which incorporate results for selecting and designing powertrain topology in consideration of the vehicle operating strategy as well as results for handling the reliability of new powertrain components. The field of investigation spans from the identification of ecologically optimal transformation of the existent vehicle fleet to the development of machine learning-based operating strategies and the comparison of complex hybrid electric vehicle topologies to reduce CO2 emissions.

Download or read book Driving and Engine Cycles written by Evangelos G. Giakoumis and published by Springer. This book was released on 2016-12-09 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents in detail the most important driving and engine cycles used for the certification and testing of new vehicles and engines around the world. It covers chassis and engine-dynamometer cycles for passenger cars, light-duty vans, heavy-duty engines, non-road engines and motorcycles, offering detailed historical information and critical review. The book also provides detailed examples from SI and diesel engines and vehicles operating during various cycles, with a focus on how the engine behaves during transients and how this is reflected in emitted pollutants, CO2 and after-treatment systems operation. It describes the measurement methods for the testing of new vehicles and essential information on the procedure for creating a driving cycle. Lastly, it presents detailed technical specifications on the most important chassis-dynamometer cycles around the world, together with a direct comparison of those cycles.

Download or read book Diesel Engine Transient Operation written by Constantine D. Rakopoulos and published by Springer Science & Business Media. This book was released on 2009-03-10 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, the study of internal combustion engines operation has focused on the steady-state performance. However, the daily driving schedule of automotive and truck engines is inherently related to unsteady conditions. In fact, only a very small portion of a vehicle’s operating pattern is true steady-state, e. g. , when cruising on a motorway. Moreover, the most critical conditions encountered by industrial or marine engines are met during transients too. Unfortunately, the transient operation of turbocharged diesel engines has been associated with slow acceleration rate, hence poor driveability, and overshoot in particulate, gaseous and noise emissions. Despite the relatively large number of published papers, this very important subject has been treated in the past scarcely and only segmentally as regards reference books. Merely two chapters, one in the book Turbocharging the Internal Combustion Engine by N. Watson and M. S. Janota (McMillan Press, 1982) and another one written by D. E. Winterbone in the book The Thermodynamics and Gas Dynamics of Internal Combustion Engines, Vol. II edited by J. H. Horlock and D. E. Winterbone (Clarendon Press, 1986) are dedicated to transient operation. Both books, now out of print, were published a long time ago. Then, it seems reasonable to try to expand on these pioneering works, taking into account the recent technological advances and particularly the global concern about environmental pollution, which has intensified the research on transient (diesel) engine operation, typically through the Transient Cycles certification of new vehicles.
