1.1 This SAE Recommended Practice covers the design and application of primary on-board wiring distribution system harnessing for surface vehicles. This document is intended for single phase nominal 120 VAC circuits that provide power to truck sleeper cab hotel loads so that they may operate with the main propulsion engine turned off. The power supply comes from alternative sources such as land-based grid power, DC-AC inverters and auxiliary power generators. The circuits may also provide power to improve vehicle performance through charging batteries or operating cold-weather starting aids. 1.2 This document is not intended to provide guidance for electric or hybrid electric vehicle wiring circuits. Refer to SAE J1673 for high voltage automotive wiring assembly design. 1.3 Engine block heaters are 120 VAC devices that are used on a multitude of vehicle platforms in addition to trucks with sleeper cabs. Generally, the engine block heater circuit is wired independent of hotel loads.

ARP1308D
The intent of this ARP is to identify electrical connectors maintained by the AE-8C1 Committee, to provide their general application characteristics, associated configuration options, and recommendations for new design (see 6.1.1), repair, and retrofit purposes (see 6.1). It is acknowledged the connectors listed herein will not completely satisfy all mobility vehicle and equipment requirements, but optimization of the use of these components will facilitate standardization in the form of maximum utilization of a minimum variety of connectors. This ARP only pertains to AS connector standards. See MIL-STD-1353 for U.S. military specification connector information.

This document is used for placing Configuration Management Requirements on Defense Contracts after being tailored by the Acquirer. When effectively and consistently applied, Configuration Management (CM) provides a positive impact on product quality, cost, and schedule. The planning and execution of Configuration Management (CM) is an essential part of the product development and life cycle management process. It provides control of all configuration documentation, physical parts and software representing or comprising the product. Configuration Management's overarching goal is to establish and maintain consistency of a product's functional and physical attributes with its requirements, design and operational information throughout its life cycle. When effectively and consistently applied, Configuration Management (CM) provides a positive impact on product quality, cost, and schedule.

Oil debris monitoring in aero engines In a gas turbine engine, small particles or "chips" are generated at the point of wear, serving as an advanced warning that catastrophic failure will occur if the wear is not addressed. Health monitoring systems, such as oil debris monitoring, are used to find these small particles so that the wear can be resolved before it's too late. Indigenous powertrain development Customer needs and expectations on drivability, fuel economy, and safety has pushed Indian and multinational OEMs to think about the development of powertrains and gearboxes for local needs with global standards. The next wave of crash simulation As computing speed has improved and software itself has made significant speed and performance gains with each release, modeling tools are now quick enough to build high-quality, large, high-detail vehicle models in a very efficient manner.

Abstract In this work, in-cylinder pressure was measured in a 55 cc single cylinder, 4.4 kW, two stroke, spark ignition engine. In cylinder pressure measurements were taken using two different pressure transducers to determine if the performance differences between the two transducers are discernible in a small, spark ignition engine. A Kistler brand measuring spark plug was compared to a Kistler brand flush mount high temperature pressure sensor. Both sensors employ piezo-electric pressure sensing elements and were designed to measure indicated mean effective pressure as well as to detect knock at high temperature engine conditions. The pressure sensors were installed and adjusted to ensure cylinder volume after sensor installation matched the engine's original configuration within reasonable manufacturing tolerances. A series of tests at four throttle settings ensued to determine if either device altered the combustion volume or the engine's performance.
