Summaries of technical papers
NOx emissions inventories – Role of improved HD ICE technologies
A new in-use emissions study on heavy-duty vehicles shows that both conventional diesel and alternative fuel vehicles certified to the 0.02 g/bhp-h standard can meet future EPA NOx limits even in day-to-day operation.
Direct manufacturing cost of BEV vs ICE
A summary of a study comparing the direct manufacturing costs of the VW Tiguan and ID4
True total cost of ownership still a decade away
New study analyzes the cost of transition to electric vehicles in California, including socio-economic factors. The burden will shift to lower income groups in later years.
Preparing for Euro VII : Sub-23 nm particles
Starting with Euro 7 regulations in Europe, particles down to 10 nm will be counted and regulated, a change from the current cut-off of 23 nm, reflecting both the increasing awareness of health impact due to ultra-fine particles and also improved measurement capabilities. We give an overview of the issue.
A good review of lithium-ion battery cost reductions
This publication by Micah Ziegler and Jessika Trancik from MIT explores the correlation of the decline in price with improved technology (Moore’s Law), cumulative production (Wright’s Law), annual production (Goddard’s Law) and R&D activity as measured via patent filings.
Designing Next Generation Exhaust Aftertreatment Systems Using Machine Learning
Machine Learning (ML) techniques are increasingly being used to reduce development costs and timelines for emissions control design optimization. This article provides a summary of a recent paper by a leading OEM, which discusses the approach.
