Convocation of eagles takes over bed of Nissan pickup

Let this be a lesson to those of you who plan to visit Unalaska, Alaska (yes, it's a real city on Unalaska Island in the Aleutian Islands): If you park at Safeway with a garbage bag full of fish fillets in your pickup's bed, the eagles will find you. That's what happened above when an unidentified man parked his Nissan and returned to find a convocation of bald eagles feasting on his fish.
Neither the man nor those parked near his truck could get to their cars for fear of getting a beatdown from The 'Murica Bird, and police were called to break it up, which they did with neither beast nor fowl injured in the process.
Other than being awesome watching, other things we can take away from this video are the question who comes up with bird gathering names (a "murmuration" of herons and an "unkindness" of ravens?), and the bounty of this comment left by user "Abraham" at the KUCB news report: "It's just that the luxury edition has so much more eagle, it saddens me to think of you missing out." See what caused it all in the video below.

Nissan sees its EV sales surging to 1 million annually by 2022

YOKOHAMA, Japan — Nissan announced plans to sell 1 million electric vehicles (EVs) annually by 2022, a six-fold jump from what it sold last year, and said it had no plans to stop testing its self-driving cars on public roads, calling them safe. Japan's No. 2 automaker and its rivals are planning to crank up development and production of electric cars in response to tightening emissions regulations around the world, even as demand for such vehicles remains limited due to their high cost and limited charging infrastructure. Launched as the world's first mass-market all-battery EV in 2010, Nissan's Leaf compact hatchback is the world's best-selling EV, though sales have been just around 300,000 units in its lifetime. The company now plans to focus its lower-emissions lineup on all-battery and gasoline-hybrid EVs rather than costlier technologies including plug-in hybrids. Nissan said on Friday it would develop eight new all-battery EVs over the next five years, including four models for China. Its luxury Infiniti brand would begin carrying new electric models from 2021, it added. Through 2022, vehicles powered by its "e-Power" gasoline-hybrid technology would likely comprise the majority of Nissan's electric line-up, it said. Such vehicles use gasoline to power the car's motor, requiring a much smaller battery than EVs and therefore are less expensive to produce. "The heart of our strategy in terms of electrification is battery EVs and e-Power technology," Nissan Chief Planning Officer Philippe Klein told reporters at a briefing. Concerns about EV battery costs and components have prompted many automakers to develop a variety of lower emissions technologies, but Klein said that Nissan would largely forego plug-in hybrids and hydrogen fuel cell technologies, given their low cost-performance at the moment. In 2017, Nissan sold 163,000 electric vehicles globally. Nissan and its automaking partners, Renault and Mitsubishi, together plan to launch 17 electric models as part of their strategy to achieve annual vehicle sales totaling 14 million units by 2022, compared with 10.6 million units in 2017. Self-driving tests to continue Automakers and technology companies are facing mounting pressure to prove that their automated driving functions under development are safe to use on public roads following a fatal accident involving a self-driving car operated by Uber Technologies [UBER.UL] in the United States earlier this week.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
