Variable Valve Actuation Design and Performance Impact on Advanced Powertrains

2019-06-17
Engine valvetrain systems have become more capable and increasingly more compact in the quest to improve efficiency. The developments parallel the advancements in other key engine components such as fuel injection or spark systems, turbocharging, aftertreatment, base engine and controls. While the gasoline sector has seen a steady rise in the adoption of Variable Valve Actuation (VVA), Diesel systems have lagged behind and only a few systems have seen production. The level of VVA activity however in the Diesel sector is beginning to increase as tighter regulations of CO2 emissions approach.

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.

Crane Hoist Line Speed and Power Test Procedure

2017-06-07
CURRENT
J820_201706
This document applies primarily to mobile cranes that lift loads by means of a drum and hoist line mechanism. It can be used to determine the hoist line speed and power of other hoist line mechanisms, if the load can be held constant and hoist line travel distance is sufficient for the accuracy of the line speed measurements prescribed. This recommended practice applies to all mechanical, hydraulic, and electric powered hoist mechanisms.

J3046/1_199411
This part of ISO 3046 specifies standard reference conditions and methods of declaring the power, fuel consumption, lubricating oil consumption, and test methods for reciprocating internal combustion (RIC) engines in commercial production using liquid or gaseous fuels. Where necessary, individual requirements are given for particular engine applications. This part of ISO 3046 covers RIC engines for land, rail-traction, and marine use, excluding engines used to propel agricultural tractors, road vehicles, and aircraft. This part of ISO 3046 may be applied to engines used to propel road construction and earthmoving machines, industrial trucks, and for other applications where no suitable International Standard for these engines exists. This part of ISO 3046 may be applied to tests on a test bed at the manufacturer's works and to tests on site.

Internal Combustion Engines-Piston Rings Expander/Segment Oil Control Rings

1992-09-01
HISTORICAL
J2004_199210
This SAE Standard is equivalent to ISO Standard 6627 TR. Differences, where they exist, are shown in Appendix A with associated rationale. This SAE Standard specifies the dimensional features of commonly used oil control rings having two steel segments (rails) separated and expanded by one steel expander/spacer. The segments vary in width from 0.4 to 0.6 mm. The assembly width ranges from 2.5 to 4.75 mm. The 4.75 mm width is equivalent to existing 3/16 in applications. Expander design will vary considerably with piston ring manufacturer. The total circumferential deflection and the piston groove depth should be considered when designing these oil rings to optimize the fit of the ring assembly into the piston groove. This document applies to oil control rings up through 125 mm for reciprocating internal combustion engines. It may also be used for piston rings of compressors working under similar conditions.

Internal Combustion Engines--Piston Rings--Rectangular Rings With Narrow Ring Width

J1998_199006
This SAE Standard specifies the essential dimensional features of R, B, and M rectangular piston ring types with narrow ring width. Dimensional tables 8 and 9 allow for the use of cast iron (table 8) or steel (table 9). Since the modulus of elasticity of steel rings is higher than that of cast iron rings, the fluctuation in the surface pressure will become greater if the free gap is set as the reference for force. Therefore, forces are set using the surface pressure as the reference, in order to minimize the effect of the fluctuation. The requirements of this document apply to rectangular rings for reciprocating internal combustion engines up to and including 90 mm diameter for cast iron rings and up to and including 100 mm diameter for steel. They may also be used for piston rings of compressors working under similar conditions.

Internal Combustion Engines--Piston Rings--Quality Requirements

CURRENT
J1996_200806
This SAE Standard specifies the quality aspects that are capable of definition but not normally found on a drawing specification. The difficulty of trying to define in absolute terms the quality attainable in normal commercial manufacture of piston rings is well known. In this document the commonly encountered aspects of quality in terms of casting defects and other departures from ideal are quantified. Many minor defects are clearly quite acceptable; other defects because of size or numbers are inadmissible. This document covers the following: a) Single piece piston rings of grey, carbidic, malleable, spheroidal graphite cast iron or steel; b) Multipiece pistong rings (oil control rings) consisting of cast iron parts and spring components; c) Single piece and multipiece rings of steel, i.e., oil control rings in the form of strip steel components or steel segments (rails) with spring expander components.
