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.

Recharge Wrap-up: Toyota battery breakthrough, PSA's millionth BlueHDi diesel

Scientists at Toyota have developed battery technology that allows for higher energy density. Using material from hydrogen storage, researchers at the Toyota Research Institute of North America (TRINA) in beautiful Ann Arbor, Michigan have created an electrolyte that works well with a magnesium metal anode. Besides improving energy density for smaller, more powerful batteries, magnesium is also more stable than lithium, making it a safer alternative. Rather than guarding their secret, Toyota is sharing details of this breakthrough in order to advance the technology in hopes of an earlier mass deployment of magnesium batteries. See the video above, and read more in the press release below. Farmdrop – a sort of online farmer's market in the UK – is looking for help naming its electric delivery "vanimals." The Nissan e-NV200 vans are painted and decorated to look like cows, pigs, and chickens. While three of the vans have already been named, fans can suggest their own clever ideas for the rest of the fleet on social media. Those whose names are selected will win a month's worth of shopping on Farmdrop. Cary McCarface, anyone? Read more at the company's website. PSA has built its millionth Euro 6 BlueHDi diesel engine. The automaker builds two diesel engines – a 1.6-liter and a 2.0-liter – at its plant in Tremery, France at a rate of 7,000 engines a day. BlueHDi technology uses three different emissions control mechanisms to filter pollutants out of diesel exhaust, including an oxygen catalyst, an additive filter to remove particulate matter, and a Selective Catalytic Reduction system to reduce NOx. BlueHDi is used in all new Peugeot, Citroen, and DS Euro 6 diesel vehicles. Read more at Green Car Congress. Charging Ahead Toyota Scientists Make Breakthrough on Safer, Smarter Batteries May 04, 2016 ANN ARBOR, Mich. (May 4, 2016) -- For anyone (i.e. everyone) who's ever panicked when their mobile device chirped, "low battery," the future could be far less stressful, thanks to the advanced battery research of scientists at the Toyota Research Institute of North America (TRINA). A new breakthrough involving magnesium batteries may soon open the doors for smaller, longer-lasting batteries for everything from cars to cell phones. What's the Big Deal with Magnesium? Magnesium metal has long been theorized as a much safer and more energy-dense alternative to current lithium battery technology.

The UK votes for Brexit and it will impact automakers

It's the first morning after the United Kingdom voted for what's become known as Brexit – that is, to leave the European Union and its tariff-free internal market. Now begins a two-year process in which the UK will have to negotiate with the rest of the EU trading bloc, which is its largest export market, about many things. One of them may be tariffs, and that could severely impact any automaker that builds cars in the UK. This doesn't just mean companies that you think of as British, like Mini and Jaguar. Both of those automakers are owned by foreign companies, incidentally. Mini and Rolls-Royce are owned by BMW, Jaguar and Land Rover by Tata Motors of India, and Bentley by the VW Group. Many other automakers produce cars in the UK for sale within that country and also export to the EU. Tariffs could damage the profits of each of these companies, and perhaps cause them to shift manufacturing out of the UK, significantly damaging the country's resurgent manufacturing industry. Autonews Europe dug up some interesting numbers on that last point. Nissan, the country's second-largest auto producer, builds 475k or so cars in the UK but the vast majority are sent abroad. Toyota built 190k cars last year in Britain, of which 75 percent went to the EU and just 10 percent were sold in the country. Investors are skittish at the news. The value of the pound sterling has plummeted by 8 percent as of this writing, at one point yesterday reaching levels not seen since 1985. Shares at Tata Motors, which counts Jaguar and Land Rover as bright jewels in its portfolio, were off by nearly 12 percent according to Autonews Europe. So what happens next? No one's terribly sure, although the feeling seems to be that the jilted EU will impost tariffs of up to 10 percent on UK exports. It's likely that the UK will reciprocate, and thus it'll be more expensive to buy a European-made car in the UK. Both situations will likely negatively affect the country, as both production of new cars and sales to UK consumers will both fall. Evercore Automotive Research figures the combined damage will be roughly $9b in lost profits to automakers, and an as-of-yet unquantified impact on auto production jobs. Perhaps the EU's leaders in Brussels will be in a better mood in two years, and the process won't devolve into a trade war. In the immediate wake of the Brexit vote, though, the mood is grim, the EU leadership is angry, and investors are spooked.
