The new Bosch Automotive Handbook, now in its 9th English edition, has been completely revised and enhanced to include the most recent developments in automotive technology. About 200 specialist authors contributed to this new version of every engineer’s must-have reference. The book's format has been revised: it is now 20 percent longer and wider, as this allows for a larger font size. This makes the texts and graphics easier to read. The index has been strongly expanded to make looking up technical terms easier. The Bosch Automotive Handbook is a best-seller, with a broad global readership. Students of engineering programs consult it, as do researchers and engineers in the automotive industry. Mechanics who are studying to become master craftsmen also use it as a reference work. Experts trust the well-founded and extensive expertise that can be found in the classic. The Bosch Automotive Handbook is widely regarded around the world as a standard work for automotive technology. Until now, it has been translated into 11 languages.

J2931/4_201410
This SAE Technical Information Report SAE J2931/4 establishes the specifications for physical and data-link layer communications using broadband Power Line Communications (PLC) between the plug-In electric vehicle (PEV) and the electric vehicle supply equipment (EVSE) DC off-board-charger. This document deals with the specific modifications or selection of optional features in HomePlug Green PHY v1.1 (HomePlug GP1.1) necessary to support the automotive charging application over Control Pilot lines as described in SAE J1772™. PLC may also be used to connect directly to the Utility smart meter or home area network (HAN), and may technically be applied to the AC mains, both of which are outside the scope of this document.

AIR4982A
This SAE Aerospace Information Report (AIR) has been prepared to provide information regarding options for optical control of fluid power actuation devices. It is not intended to establish standards for optical fluid power control, but rather is intended to provide a baseline or foundation from which standards can be developed. It presents and discusses approaches for command and communication with the actuation device via electro-optic means. The development of standards will require industry wide participation and cooperation to ensure interface commonality, reliability, and early reduction to practice. To facilitate such participation, this document provides potential users of the technology a balanced consensus on its present state of development, the prospects for demonstration of production readiness, and a discussion of problem areas within this technology. The intent is to inform the user/designer of the options available for interfacing photonics (optics) to hydraulic power control actuators used in aerospace applications.

Electronic parts are used throughout industry to run everyday products, such as cell phones, and also highly technical products, such as aircraft, missiles, and spacecraft. Unlike cell phones, which are often replaced every year, the highly technical products may remain in service from 20 to more than 80 years. But what happens if the original electronic part, with a life cycle of 18 months, is no longer available? Some manufacturers have discovered that they have unwittingly purchased counterfeit ones. Counterfeit Electronic Parts and Their Impact on Supply Chains examines how these items are negatively affecting the aviation, spacecraft, and defense sectors and what can be done about it. As the inflow of counterfeit electronic parts does not appear to be slowing down, Counterfeit Electronic Parts and Their Impact on Supply Chains investigates the possible solutions to combat the issue, including legislation and standards, and other solutions that are government driven but that may be impacted by continuing budget cuts.

This procedure measures the resistance to radiant heat flow of insulating materials in sleeve form. The sleeve's effectiveness (S{sub}E) 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.

AS81511
This specification covers four series of electrical connectors (plugs and receptacles) with removable crimp contacts and accessories (see 6.1). AS81511 connectors are not recommended for new design. All AS81511 detail sheets that specified class D and/or H have been cancelled without replacement, therefore all class D and H requirements have been deleted from this specification.

J2572_201410
This SAE Recommended Practice establishes uniform procedures for testing fuel cell and hybrid fuel cell electric vehicles, excluding low speed vehicles, designed primarily for operation on the public streets, roads and highways. The procedure addresses those vehicles under test using compressed hydrogen gas supplied by an off-board source or stored and supplied as a compressed gas onboard. This practice provides standard tests that will allow for determination of fuel consumption and range based on the US Federal Emission Test Procedures, using the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS). Chassis dynamometer test procedures are specified in this document to eliminate the test-to-test variations inherent with track testing, and to adhere to standard industry practice for fuel consumption and range testing. Communication between vehicle manufacturer and the governing authority is essential when starting official manufacturer in-house and official government confirmatory testing that incorporates this practice.
