Ford pumps powertrains for 2018 F-15017AUTP09_129/1/2017
It's tough at the moment to sell a car to a U.S. customer, so wily automakers-or those at a fortuitous place in their product cycles-are doubling down on trucks and crossovers. Regardless of that, nobody would ever expect Ford to hang back when it comes to keeping the F-Series pickup fresh, so for 2018 the light-duty F-150 line gets a light face-freshening and tasty rework of its powertrain lineup. At the starting end of the F-150's current five-engine range, the former 3.5-L V6 is reduced to 3.3-L, but fear not: its all-new cylinder heads accommodate the twin direct-injection (DI) and port fuel-injection (PFI) setup that all 2018 F-150 engines use, so horsepower is up by eight, to 290 hp, and torque runs to 265 lb·ft (359 N·m), a 12 lb·ft (16 N·m) hike.

Taking Heavy Duty Diesel Engine Oil Performance to the Next Level, Part 2: Optimizing for Universal Applicability2014-01-279510/13/2014
Advancement in Heavy Duty Diesel Engine Oils has, for approximately two decades, been driven by the ever more stringent emission legislation for NOx and Particulates. Over the last few years, the focus has shifted to reducing CO2 emissions and reducing operating cost by improving the engine's fuel economy. With fuel economy as an important new technology driver, the industry is exploring and introducing diesel engine oils of viscosity grades that used to be applied solely in passenger car engines, such as SAE 10W-30 and even SAE 5W-30. To avoid misapplication, API has decided that heavy duty diesel engine oils, most of which are formulated close to the maximum 0.12% phosphorus limit in the API C specification, can no longer add the API S gasoline engine claim. The only way to create a lubricant that carries both an API C and S claim for mixed fleet or municipality application, is to formulate at less than 0.08% phosphorus, a limit that was adopted in API S specifications because there are indications that phosphorus may foul three-way catalysts used with gasoline engines to control tailpipe emissions. And there lies the dilemma. The market wants to move to lower viscosity grades and maintain all the capabilities that current diesel engine oils exhibit, including universal applicability in both diesel and gasoline engines, and the robustness that is required for extended drain capability and engine durability. The conclusion seems obvious: A real performance upgrade to maintain engine durability despite lower viscosity and a lower phosphorus limit, is necessary. This publication describes the steps that were taken to successfully meet the seemingly contradicting demands of tomorrow's diesel engine oils, and thereby takes the performance of a new generation of diesel engine oils to the next level.

Engineering for the aftermarketAUTONOV05_0511/1/2005
Suppliers that serve the OE market are setting their sights on the growing market for customization. If the annual SEMA Show, which convenes in Las Vegas every November, is an accurate reflection of the automotive accessories market, then business for the industry's participants is booming. With 2000-plus exhibitors expected to fill more than 1 million ft2 (92,900 m2) of space this year, the Specialty Equipment Market Association (SEMA) has expressed concerns that its show may soon outgrow the Las Vegas Convention Center, already one of the largest such facilities in the U.S. SEMA figures show that the automotive accessories industry is indeed expanding at a similarly steady pace, with $31 billion in retail sales in 2004, up 6.9% from 2003, which in turn was up 7.7% from the prior year.

Upgrades of Two Computer Codes for Analysis of TurbomachineryTBMG-2920410/1/2005
Major upgrades have been made in two of the programs reported in "Five Computer Codes for Analysis of Turbomachinery" (LEW-16851), NASA Tech Briefs, Vol. 23, No. 11 (November 1999), page 28. The affected programs are:
Performance from withinAUTOJUL05_047/1/2005
Automakers gild profit margins and polish reputations with in-house high-performance divisions. In a U.S. market defined by rising affluence and an interest in displaying it, automakers are increasingly turning to in-house high-performance divisions to produce limited-production specialty models. These high-performance divisions are typically modeled on BMW's Motorsport Division and produce vehicles that are differentiated with unique bodywork, powerful engines, taut suspension, and massive brakes. Once seen perhaps as an interesting afterthought, or even as an exercise in corporate ego, performance divisions can be big business. The granddaddy of them all is BMW's Motorsport (or M) Division, founded in 1972. The rationale of its creation is a German colloquialism that maintains that “If you want to go racing, you go to the green meadow,” said Friedbert Holz, spokesman for M. That means that a racing program is better conducted outside the restrictive confines of a corporate bureaucracy, he explained. Not coincidentally, the first director of the M division was Bob Lutz, who more recently instituted General Motors' own performance division.

A view from insideAUTOMAY05_055/1/2005
Consumers in general seek comfort, convenience, and entertainment from their purchases, and that is increasingly true for vehicles, which deliver these attributes largely through inviting and engaging interiors. While the exterior is what initially draws a customer to a vehicle and is an outward statement to the surrounding community of who he or she is, the interior is where the person spends his or her time and can largely determine the buyer's experience with the vehicle. And people are spending more time than ever in their vehicles. According to the U.S. Census Bureau's recent American Community Survey, Americans now drive about 24.3 min on average to get to work. Over the course of a year, they spend more than 100 h commuting to work-more than the average 80 h of vacation time many workers take during that same time.

Interplanetary and Lunar Surface SP-100 Nuclear Power Applications9294458/3/1992
This paper describes how the SP-100 Space Reactor Power System (SRPS) can be tailored to meet the specific requirements for a lunar surface power system to meet the needs of the consolidation and utilization phases outlined in the 90-day NASA SEI study report. This same basic power system can also be configured to obtain the low specific masses needed to enable robotic interplanetary science missions employing Nuclear Electric Propulsion (NEP). In both cases it is shown that the SP-100 SRPS can meet the specific requirements. For interplanetary NEP missions, performance upgrades currently being developed in the area of light weight radiators and improved thermoelectric material are assumed to be technology ready in the year 2000 time frame. For lunar applications, some system rearrangement and enclosure of critical components are necessary modifications to the present baseline design.

Design Considerations for Automotive Entertainment System Loudspeakers8400822/1/1984
In the last few years an increased emphasis on high performance OEM sound systems has been paralleled by concomitant upgrades in loudspeaker ratings and requirements. These performance upgrades have been realized, despite space considerations that limit the package size of the speaker. Through an analysis of low frequency performance simulations and specific cone radiation behavior, a rough estimate of performance vs. package size is possible; thereby identifying potential tradeoffs before engaging in a lengthy prototype phase.
