FEA Beyond Basics Thermal Analysis

2019-12-16
Finite Element Analysis (FEA) is a powerful and well recognized tool used in the analysis of heat transfer problems. However, FEA can only analyze solid bodies and, by necessity thermal analysis with FEA is limited to conductive heat transfer. The other two types of heat transfer: convection and radiation must by approximated by boundary conditions. Modeling all three mechanisms of heat transfer without arbitrary assumption requires a combined use of FEA and Computational Fluid Dynamics (CFD).

Electronic Transmission Controls

2000-06-10
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.

Concepts in Turbocharging for Improved Efficiency and Emissions Reduction

2014-09-22
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.

Thermal Effectiveness of Sleeve/Tubing/Tape Insulation

2017-03-15
CURRENT
J2302_201703
This procedure measures the resistance to radiant heat flow of insulating materials in sleeve, tubing or tape (collectively referred to as “sleeve”) form. The sleeve’s effectiveness (SE) is determined by measuring the difference in surface temperature of a flat black, single-diameter ceramic cylinder with and without the standard diameter sleeve at the specified temperature, position, and distance from the radiant heat source.

Engine Preheaters

1986-01-01
HISTORICAL
J226_198601
This SAE Standard describes electric immersion engine preheaters for use in the coolant jacket of heavy-duty and intermediate size diesel engines. This document gives the dimensional information of the four basic styles of engine preheaters. The tables for each style will list the wattage commonly used. Small engines that typically require less than 600 W of preheat for cold weather starter are not covered by this document. These types of engines generally have very little space available to accommodate an immersion heater of the styles presented in this document. The purpose of this document is to establish commonality of engine preheater designs. The user of this document can use these current styles and wattages early on in their designing. This will give the user of this document a good engine preheater design.
