Injection Technologies and Mixture Formation Strategies For Spark-Ignition and Dual-Fuel Engines

2022-06-24

Fuel injection systems and performance is fundamental to combustion engine performance in terms of power, noise, efficiency, and exhaust emissions. There is a move toward electric vehicles (EVs) to reduce carbon emissions, but this is unlikely to be a rapid transition, in part due to EV batteries: their size, cost, longevity, and charging capabilities as well as the scarcity of materials to produce them. Until these issues are resolved, refining the spark-ignited engine is necessary to address both sustainability and demand for affordable and reliable mobility. Even under policies oriented to smart sustainable mobility, spark-ignited engines remain strategic, because they can be applied to hybridized EVs or can be fueled with gasoline blended with bioethanol or bio-butanol to drastically reduce particulate matter emissions of direct injection engines in addition to lower CO2 emissions.

Acoustical Materials: Solving the Challenge of Vehicle Noise

2021-08-11

Journal of the Acoustical Society of America Book Review INCE/NCEJ Book Review What is acoustics? What is noise? How is sound measured? How can the vehicle noise be reduced using sound package treatments? Pranab Saha answers these and more in Acoustical Materials. Acoustics is the science of sound, including its generation, propagation, and effect. Although the propulsion sources of internal combustion engine (ICE) vehicles and electric motor-powered vehicles (EV) are different and therefore their propulsion noises are different, both types of vehicles have shared noise concerns: Tire and road noise Wind noise Vehicle noise and vibration issues have been there almost from the inception of vehicle manufacturing. The noise problem in a vehicle is very severe and is difficult to solve only by modifying the sources of noise and vibration. Sound package treatments address the noise and vibration issues along the path to reduce in-cabin noise.

Reducing Particulate Emissions in Gasoline Engines

2018-11-28

For years, diesel engines have been the focus of particulate matter emission reductions. Now, however, modern diesel engines emit less particles than a comparable gasoline engine. This transformation necessitates an introduction of particulate reduction strategies for the gasoline-powered vehicle. Many strategies can be leveraged from diesel engines, but new combustion and engine control technologies will be needed to meet the latest gasoline regulations across the globe. Particulate reduction is a critical health concern in addition to the regulatory requirements. This is a vital issue with real-world implications. Reducing Particulate Emissions in Gasoline Engines encompasses the current strategies and technologies used to reduce particulates to meet regulatory requirements and curtail health hazards - reviewing principles and applications of these techniques.

Project Management for Automotive Engineers: A Field Guide

2016-09-01

Project Management for Automotive Engineers: A Field Guide was developed to help automotive engineers be better project managers as automotive projects involve suppliers dispersed across the globe, and can often span multiple years. Project scope change is common, and so too are the budget constraints and tight deadlines. This book is an excellent guide on how to manage continuous change. As project management in this particular industry is intrinsically linked to product development, the chapters focus on the project management aspects that are significant during the various stages of a product development cycle, including business case evaluation, process development cycle, test phases, production ramp up at the plant and at the Tier 1 supplier level, and how to work within a matrix-structured organization. The principles of value projects and how to revive failing projects are discussed.

Two-Wheelers, Micro-EVs (Quadricycles), Mobility for Disabled 2013-2023

2014-11-01

This report looks closely at global trends in light electric vehicles’ (LEVs) technology, manufacture and market drivers such as legislation and the fact that several Chinese cities are banning or severely restricting LEVs. In the last few years, nearly every nation has bought ebikes from China, and in some cases, the volumes are now significant. Sales will reach 130 million yearly before 2025, making it one of the world's largest industries. The report encompasses over 70 brands, and gives forecasts of sales numbers, unit prices and total market value for 2013-2023. A significant percentage of ebikes sold are scooters in that they have the driver's feet rest on a platform - they are not straddled by the driver. Today, the LEV industry is dominated by large bicycle companies, due to their access to distribution. In the future, these companies will face major competition, and may be pushed aside by car, motorcycle, and car parts companies.

Analysis Techniques for Racecar Data Acquisition, Second Edition

2014-02-24

Racecar data acquisition used to be limited to well-funded teams in high-profile championships. Today, the cost of electronics has decreased dramatically, making them available to everyone. But the cost of any data acquisition system is a waste of money if the recorded data is not interpreted correctly. This book, updated from the best-selling 2008 edition, contains techniques for analyzing data recorded by any vehicle's data acquisition system. It details how to measure the performance of the vehicle and driver, what can be learned from it, and how this information can be used to advantage next time the vehicle hits the track. Such information is invaluable to racing engineers and managers, race teams, and racing data analysts in all motorsports. Whether measuring the performance of a Formula One racecar or that of a road-legal street car on the local drag strip, the dynamics of vehicles and their drivers remain the same. Identical analysis techniques apply.

Lumbar Injury Biomechanics

2013-08-01

The amount of load that can be borne by the different components of the lumbar region is fairly well understood, as are resulting injuries from overloading. Less severe lumbar injuries involve a wide range of factors, including: heredity, obesity, age, occupation, sports, cardiovascular risk factors, and depression. Some of the most painful conditions that require high levels of care involve lumbar spine fracture or soft tissue injury from falls, contact sports, vehicle collisions, aircraft ejection, and underbody blasts from roadway explosions (military injuries). Each of these injury scenarios elicits a different kinematic response of the spine as a result of load direction, magnitude, and duration. Updated from a popular earlier volume, this new compendium includes landmark papers from 1994 through 2013 that focus exclusively on lumbar injuries.

Vehicle Occupant Restraint Systems: Trends, Companies, Market Forecasts to 2020

2012-07-01

With an ever greater value placed on safety by consumers, vehicle manufacturers around the world are rushing to develop new and innovative safety systems. The average safety content per vehicle has risen 17% since 2004 to around $270 per car in 2012. And this figure is set to grow, both in the established markets of North America, Western Europe and Japan, as well as the developing markets such as China and Brazil. But although the prospects look good for the major suppliers of conventional and advanced occupant safety systems, increasing unit growth will be partly offset by strong pricing pressure from vehicle manufacturers. Brand new research on automotive vehicle occupant restraint systems The 2012 edition of this report reviews the key market drivers for vehicle occupant restraint systems, extending and updating the analysis originally published in 2004, as well as reviewing the trends in the intervening eight years.
