Life-cycle assessments (LCAs) conducted, to date, of the end-of-life phase of vehicles rely significantly on assumed values and extrapolations within models. The end phase of vehicles, however, has become all the more important as a consequence of increasing regulatory requirements on materials recovery, tightening disposal restrictions, and the rapid introduction of new materials and electronics, all potentially impacting a vehicle’s efficacy for achieving greater levels of sustainability. This article presents and discusses selected research results of a comprehensive gate-to-gate life-cycle-inventory (LCI) of end-of-life vehicle (ELV) dismantling and shredding processes, constructed through a comprehensive and detailed case study, and argues that managing and implementing creative dismantling practices can improve significantly the recovery of both reusable and recyclable materials from end-of-life vehicles. Although the amount of parts and materials recovered and directed for reuse, remanufacturing or recycling may be as much as 11.6% by weight of the ELVs entering a dismantling process [1], greater rates of reuse and/or recycling may be achieved by the strategic management of the ELVs entering the dismantling process according to age.

ARP4761 describes guidelines and methods for performing safety assessments. This recommended practice is associated with showing compliance with certification requirements (14CFR/CS Parts 23 and 25, section 1309) and assisting a company in meeting their own internal safety standards. The safety processes described are primarily associated with civil airborne equipment but the processes and tools may be applied to many applications. This 2 day seminar provides attendees with the guideline information for conducting industry accepted safety assessments consisting of Functional Hazard Assessment (FHA), Preliminary System Safety Assessment (PSSA), and System Safety Assessment (SSA). Discussion on various safety analysis methods needed to conduct the safety assessments is included. Safety analysis methods including Fault Tree Analysis (FTA), Dependence Diagram (DD), Markov Analysis (MA), Failure Modes and Effect Analysis (FMEA) and Common Cause Analysis (CCA). CCA is composed of Zonal Safety Analysis (ZSA), Particular Risks Analysis (PRA), and Common Mode Analysis (CMA) and will be covered in this seminar.

One of the most important aspects of meeting emission standards is catalyst robustness. Emissions must be met at high mileage, termed “full useful life”, which is 150,000 mi for light and medium duty vehicles under Tier3/LEV3. Catalyst durability is application and system specific. Full useful life aging and correlations to accelerated aging schemes typically include both hydrothermal exposure and chemical poisoning. Robustness tests are designed to exceed the limits of a particular catalyst or filter material and test to failure. New aging schemes and robustness tests are needed when new technologies such as cold start traps for HC and NOx, gasoline particle filters, and SCR coated filters are incorporated into conventional three-way and diesel exhaust systems. This presentation will include a summary of recent emission certifications and publications by various vehicle manufacturers, aging and robustness testing of conventional exhaust systems, as well as a look into the durability of future emission control technologies.

New rounds of stringent nitrogen oxides (NOx) emissions reduction regulations in Europe (Euro 6c) and North America (CARB LEV III, EPA Tier 3) are driving the optimization of existing diesel exhaust aftertreatment systems. Urea - Selective Catalytic Reduction (SCR) systems are among the de-NOx technologies that have been successfully introduced in recent years. The new regulations are bringing a closer look to SCR de-NOx performance particularly during the cold start phase of the existing emissions certification cycles. This presentation will review some of the options under consideration to address cold start NOx emissions. Some of these approaches impose new and more severe requirements on the urea injection function – these are also reviewed as well as the response to these requirements by the injection system designers.

Pd based catalysts has not been considered sufficient for converting methane to carbon dioxide for lean-CNG applications mainly in terms of durability, which finally impact the performance on long period. In the present investigation, we were addressed the substantial improvement of Pd-based catalyst with respect to its durability and initial activity. To obtain this, primarily the improvement was mainly achieved based on the new insight on the deactivation routes of Pd-based catalysts under normal operating condition of lean-CNG engines using various physicochemical tools. In addition, optimal engine control logic was carried in second stage of catalysts development by keeping the catalyst more durable. The system, comprised of improved Pd-based catalyst and engine control logic, has demonstrated the capability of complying EURO-6 regulations.

The automotive industry is facing a combination of challenges over the next decade. Fuel economy regulations are increasing for light-duty vehicles, and U.S. EPA Tier 3 emissions standards are requiring lower tailpipe emissions. Advanced combustion techniques are being pursued to enable improved fuel economy, and lower NOx and PM emissions can be obtained by the more homogeneous combustion from these techniques. However, CO and HC emissions are often higher from advanced combustion engines, and the higher efficiency of these engines results in lower exhaust temperatures. The combination of higher CO and HC emissions with lower exhaust temperatures challenges conventional oxidation catalysts. Thus, new catalyst technologies are being pursued to lower light-off temperatures to enable emissions compliance. Research on novel catalyst formulations for control of CO and HC emissions will be presented.
