Single-cylinder engines for combustion research
Southwest Research Institute (SwRI) has designed and manufactured two advanced single-cylinder engines for combustion research and friction analysis, as well as alternative fuel, wear, optical, crank offset, and bore-to-stroke relationship studies. The engines, one for light- and medium-duty applications and one for heavy-duty applications, can accommodate either multi-cylinder or single-cylinder heads through a custom cylinder barrel and head support shelf. They include several unique patent-pending innovations, including mechanisms that adjust compression ratios and crankshaft offsets without the need for disassembling the engine. Optical access, dynamic cam phasing, secondary balancers, and floating liner devices can be added to the standard configurations. Specs available in online "Single-Cylinder Research Engine" flyer.

Hybrid gantry stage provides precision XY/XYZ motion with linear motors, air bearings, and ball bearings
PI's new A-341 hybrid gantry XY/XYZ positioning stage provides the framework for controlled precise overhead motion that is often sought after for 3D printing, assembly, pick-and-place, alignment, inspection, and industrial automation applications. The A-341 HGS hybrid gantry is designed to combine maximum throughput with smooth and highly accurate motion in a compact envelope. It features a unique hybrid bearing design. The cross axis utilizes a frictionless air bearing guiding system, which allows for excellent velocity control, repeatability, straightness, and cleanliness. The lower dual-motor axis uses precision mechanical linear bearings for rigidity and reduced size. This combo offers an overhead gantry motion platform optimized for step and scan applications in the smallest possible form factor.
Micro-brakes for precise motion control applications
The ultra-compact 112 Model Electromag-netic Micro-Brakes from Miki Pulley ensure fast response in high-torque, demanding applications. The simple design features a stator with integrated mounting flange, proprietary composite friction liner, and armature complete with ring plate spring and hub. These brakes halt rotation mechanically by utilizing an electromagnetic field to create mechanical friction. With fast response, the brake's armature engages the stator when the coil is energized. A constant-force plate spring transfers torque to the rotating brake body, halting all motion.
Electric high-force linear actuator choices: Ball vs. roller screw

SmartMotor can handle extreme low temps
Moog Animatics has released its new Low Temperature Range (LTR) SmartMotor in two standard NEMA frame sizes: model SM17205M-LTR (the LTR-17) and model SM23165M-LTR (the LTR-23). Both motors have been meticulously engineered for robust and reliable operation in extremely frigid environments and at high altitudes. To achieve this, onboard internal heaters ensure that the motors can start up in temperatures below -40 degrees C. Other design changes allow these motors to withstand random vibrations up to 6G 10-2000 Hz, and standard IP sealing protects the motors from condensation.

Honda Insight named 2019 Green Car of the Year at Los Angeles Auto Show
2019 Honda Insight.
Honda's third-generation Insight hybrid sedan has been named Green Car Journal's 2019 Green Car of the Year at the Los Angeles Auto Show's AutoMobility LA. The award honors the vehicle that most significantly raises the bar in environmental performance while remaining within reach of most consumers.
The expanded 2019 Green Car Awards also recognized two increasingly important categories this year: the 2019 Luxury Green Car of the Year, awarded to the Jaguar I-PACE, and the 2019 Green SUV of the Year, awarded to the Mitsubishi Outlander PHEV.
The original futuristic-looking Honda Insight made waves as the first gasoline-electric hybrid production model on American roads in late 1999. Today, the all-new, third-generation Insight hybrid has reinvented itself, making a bold statement that driving enjoyment, technology prowess, and impressive 52-mpg combined fuel efficiency can come in a mainstream package with Honda's signature DNA and style.
"Today's driver wants more from a hybrid than just great fuel economy. Insight truly represents the direction Honda is pursuing with electrified vehicles, delivering style and sophisticated driving dynamics with outstanding fuel economy," said Ray Mikiciuk, assistant vice president of Honda Auto Sales. "We appreciate Green Car Journal for recognizing Honda for the fourth time with Green Car of the Year."
The Green Car of the Year was selected by Green Car Journal editors and invited jurors from highly respected efficiency and environmental organizations. This year's invited Green Car of the Year jurors include celebrity auto enthusiast Jay Leno; Jean-Michel Cousteau, president of Ocean Futures Society; Matt Petersen, president and CEO of Los Angeles Cleantech Incubator and Board Chair of Climate Mayors; Dr. Alan Lloyd, president emeritus of the International Council on Clean Transportation and Senior Research Fellow at the Energy Institute, University of Texas at Austin; Mindy Lubber, president of CERES; and Jason Hartke, president of the Alliance to Save Energy.
Along with the Honda Insight, finalists for 2019 Green Car of the Year included the Lexus ES 300h, Nissan Altima, Toyota Avalon Hybrid, and Volkswagen Jetta.
Winner of the 2019 Luxury Green Car of the Year, the Jaguar I-PACE is an impressive premium model replete with aggressive styling, great performance, and desired efficiency delivered by all-electric power. Acceleration and road-handling manners are superb and assisted with advanced Torque Vectoring by Braking and Adaptive Surface Response, lending sports car-like agility to this crossover SUV. It features a confidence-inspiring 234-mile electric driving range.
In addition to the Jaguar I-PACE, finalists in contention for Luxury Green Car of the Year were the Audi e-tron, Porsche Cayenne E-Hybrid, Range Rover P400e, and Tesla Model 3.
Mitsubishi Outlander PHEV.
Mitsubishi's Outlander PHEV, the 2019 Green SUV of the Year winner, is the automaker's formidable answer for those desiring plug-in hybrid power in an affordable, all-wheel drive SUV. Using an innovative series-parallel plug-in hybrid system, the mid-size SUV can operate on all-electric drive, conventional gas-electric hybrid drive, or series hybrid drive with the engine generating electricity to assist the battery in powering electric drive motors.
Considered with the Mitsubishi Outlander PHEV for Green SUV of the Year were finalists Cadillac XT4, Hyundai Kona, Lexus UX, and the Volvo XC40.
By virtue of their environmental achievement, all of the exceptional 2019 Green Car Awards finalists were recognized with Green Car Journal's prestigious 2019 Product of Excellence distinction.
