Caterpillar expands family of next-gen compact track loaders and skid steers

12/01/2024

Caterpillar has released a cavalcade of new compact track loaders and skid steer loaders. The new CTL models include the 275, 275 XE, 285 and 285 XE. These models join the lineup alongside the 255 and 265, which were introduced last year (www.sae.org/news/2024/02/cat-compact-loaders). The 285 and 285 XE are the largest CTLs Caterpillar has ever produced and reportedly feature greater lift height and lift and tilt breakout forces. “We are excited to launch the next-generation design for our skid steer loader line and expand the performance capabilities to more compact track loader models,” said Trevor Chase, senior product consultant and new product introduction lead for Caterpillar. “Their increased power, lift height, breakout forces, rated operating capacity (ROC) and multiple high-flow auxiliary hydraulic system options give customers a flexible, high-performance machine to get the job done

How to Test a Cognitive EW System

Reliably operating electromagnetic (EM) systems including radar, communications, and navigation, while deceiving or disrupting the adversary, is critical to success on the battlefield. As threats evolve, electronic warfare (EW) systems must remain flexible and adaptable, with performance upgrades driven by the constant game of cat and mouse between opposing systems. This drives EW researchers and systems engineers to develop novel techniques and capabilities, based on new waveforms and algorithms, multifunction RF systems, and cognitive and adaptive modes of operation

Ford pumps powertrains for 2018 F-150

17AUTP09_1209/01/2017

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 Applicability

2014-01-279510/13/2014

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

Engineering for the aftermarket

AUTONOV05_0511/01/2005

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

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 within

AUTOJUL05_0407/01/2005

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

A view from inside

AUTOMAY05_0505/01/2005

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

10/01/2001

An improved non-planar ring oscillator (NPRO) of the fiber-pigtailed type has been developed. The improvements over prior lasers of this type lie in details of design and construction that are intended to enhance mechanical stability and thereby increase the stability of optical performance

Interplanetary and Lunar Surface SP-100 Nuclear Power Applications

92944508/03/1992

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 Loudspeakers

84008202/01/1984

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
