Fuel Systems Material Selection and Compatibility with Alternative Fuels

This course will introduce the participants to the factors governing fuel-material compatibility and methods to predict and empirically determine compatibility for new alternative fuel chemistries.  By understanding the mechanisms and factors associated with chemically-induced degradation, participants will be able to assess the impact of fuel chemistry to infrastructure components, including those associated with vehicle fuel systems.  This course is unique in that it looks at compatibility from a fuel chemistry perspective, especially new fuel types such as alcohols and other biofuels. 

Electronic Transmission Controls

The evolution of the automotive transmission has changed rapidly in the last decade, partly due to the advantages of highly sophisticated electronic controls. This evolution has resulted in modern automatic transmissions that offer more control, stability, and convenience to the driver. Electronic Transmission Controls contains 68 technical papers from SAE and other international organizations written since 1995 on this rapidly growing area of automotive electronics. This book breaks down the topic into two sections. The section on Stepped Transmissions covers recent developments in regular and 4-wheel drive transmissions from major auto manufacturers including DaimlerChrysler, General Motors, Toyota, Honda, and Ford. Technology covered in this section includes: smooth shift control; automatic transmission efficiency; mechatronic systems; fuel saving technologies; shift control using information from vehicle navigation systems; and fuzzy logic control.

Measurement of Passenger Compartment Refrigerant Concentrations Under System Refrigerant Leakage Conditions

This Standard is restricted to refrigeration circuits that provide air-conditioning for the passenger compartments of passenger and commercial vehicles. This Standard includes analytical and physical test procedures to evaluate concentration inside the passenger compartment. In the early phases of vehicle evaluation, usage of the analytical approach may be sufficient without performing physical tests. The physical test procedure involves releasing refrigerant from an external source to a location adjacent to the evaporator core (inside the HVAC-Module). An apparatus is used to provide a repeatable, calibrated leak rate. If the system has multiple evaporators, leakage could be simulated at any of the evaporator locations. This standard gives detail information on the techniques for measuring R-744 [CO2] and R-1234yf [HFO-1234yf], but the general techniques described here can be used for other refrigerants as well.

Concepts in Turbocharging for Improved Efficiency and Emissions Reduction

Legislative requirements to reduce CO2 emissions by 2020 have resulted in significant efforts by car manufacturers to explore various methods of pollution abatement. One of the most effective ways found so far is by shortening the cylinder stroke and downsizing the engine. This new engine then needs to be boosted, or turbocharged, to create the full and original load torque. Turbocharging has been and will continue to be a key component to the new technologies that will make a positive difference in the next-generation engines of years to come. Concepts in Turbocharging for Improved Efficiency and Emissions Reduction explores the many ways that turbocharging will deliver concrete results in meeting the new realities of sustainable, green transportation.

Hydraulic Motor Test Procedures

This test code describes tests for determining characteristics of hydraulic positive displacement motors as used on construction and industrial machinery as referenced in SAE J1116. These characteristics are to be recorded on data sheets similar to the one shown in Figure 1. Two sets of data sheets are to be submitted: one at 49 °C (120 °F) and one at 82 °C (180 °F).

Small Engine Power and Torque Rating Procedure

This SAE Standard is applicable to small spark ignition and compression ignition engines, having a maximum of 1.0 L swept volume displacement, powering off-road applications such as lawn and garden, construction, general utility equipment, and off-highway recreational vehicles. It is not intended to cover engines powering on-road vehicles, motorcycles, or boats.

The Global Market for Automotive Turbochargers: 2015 edition

Since the last edition of this report in 2013, the demand on automakers has been relentless in terms of improving fuel economy and reducing emissions, thus driving increased sales of forced induction systems. The use of pressure charging techniques has therefore expanded significantly. Recent years have seen the ascendancy of the turbocharger and its use by almost every major global manufacturer.

The Global Market for Stop-Start Systems: Trends & Forecasts to 2020

The increasingly stringent emissions regulations faced by vehicle manufacturers have been driving the growth of more fuel-efficient conventionally powered vehicles. The ability of stop-start systems to improve vehicle carbon emissions by between 5% and 15% at very low additional cost has seen a dramatic increase in the proportion of vehicles being fitted with such systems. And this growth in demand for stop-start systems is set to increase substantially, especially in Europe, North America, China and Japan. The exclusive new report from ABOUT Automotive reviews the key market drivers for stop-start engine technology for the ‘micro hybrid’ segment and conventional internal combustion engine (ICE) vehicle applications. It sets out the market drivers and forecasts for the global stop-start systems market through to 2020 and reviews the technical advances made in stop-start technology, including the competing technologies, and the latest developments.

SAE Off-Highway Engineering 2008-04-01

Engineering a cleaner off-highway world As engine manufacturers gear up to meet the next round of stringent emissions standards, equipment manufacturers are reviewing a number of design possibilities. Plugging in for safety Electronics dig deep to help protect operators and equipment. Leveraging the best of both worlds Combustion and aftertreatment technologies help engine manufacturers balance performance with emissions reduction.

Recommend Practice for an Engineering Analysis for A/C Efficiency Credits

Under US GHG and CAFE regulations, manufacturers are required to perform confirmatory testing to validate air conditioning credits, ref. 40 CFR 86.1868–12, CO2 credits for improving the efficiency of air conditioning systems. The purpose of this Reccomended Practice is to provide manufacturers with updated criteria for the 2020 and later model years. This Recommended Practice discribes the work done by the IMAC GHG CRP to develop test procedures, publish SAE Standards and determine performance requirements to demonstrate the performance of A/C technologies from the pre-approved credit menu meeting regulatory requirements Also, enclosed in this Recommended Practice, are instructions that can be used by vehicle manufacturers in establishing an engineering analysis in lieu of performing the AC17 test on a vehicle which does not incorporate the credit-generating technologies.
