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.

Book Synopsis PEM Fuel Cell Testing and Diagnosis by : Jiujun Zhang

Download or read book PEM Fuel Cell Testing and Diagnosis written by Jiujun Zhang. This book was released on 2013-01-22. Available in PDF, EPUB and Kindle. Book excerpt: PEM Fuel Cell Testing and Diagnosis covers the recent advances in PEM (proton exchange membrane) fuel cell systems, focusing on instruments and techniques for testing and diagnosis, and the application of diagnostic techniques in practical tests and operation. This book is a unique source of electrochemical techniques for researchers, scientists and engineers working in the area of fuel cells. Proton exchange membrane fuel cells are currently considered the most promising clean energy-converting devices for stationary, transportation, and micro-power applications due to their high energy density, high efficiency, and environmental friendliness. To advance research and development of this emerging technology, testing and diagnosis are an essential combined step. This book aids those efforts, addressing effects of humidity, temperature and pressure on fuel cells, degradation and failure analysis, and design and assembly of MEAs, single cells and stacks. Provides fundamental and theoretical principles for PEM fuel cell testing and diagnosis. Comprehensive source for selecting techniques, experimental designs and data analysis Analyzes PEM fuel cell degradation and failure mechanisms, and suggests failure mitigation strategies Provides principles for selecting PEM fuel cell key materials to improve durability
