A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

Nissan pulling Facebook ads over hate speech concerns

The system for advertising on Facebook allows companies to target specific demographics with ads that follow people based on their personal information, but as some companies have been finding out lately, this could lead to their ads showing up on questionable pages. According to Automotive News and The New York Times, Nissan has joined a growing list of companies that has pulled its advertising until the social media giant can guarantee that the ads won't appear on offensive pages.
This issue came about as a result of a group calling for Facebook to ban gender-based hate speech that went unchecked on some fan pages. Apparently, some of these offensive pages even showed images of women being abused. We won't post the names of the offensive pages, but you can find some of them listed on the NYT article, though it looks like most of the pages have since been removed. As for Nissan, AN says that the only ads it had at the time were for Nissan UK, and there is no telling how this issue will affect Facebook advertising in the future.

Angry Nissan Leaf Driver may make 'Rolling Coal' illegal in New Jersey

It's always a few bad apples who ruin polluting just for fun for the rest of us. That time-honored American tradition of being rude for laughs, otherwise known as 'rolling coal,' might become illegal in New Jersey, if a Nissan Leaf-driving politician gets his way. The politician in question is State Assemblyman Tim Eustace (D-Bergen), who was purposefully hit by a blast of dark smoke recently while driving his Leaf on the New Jersey Turnpike, according to NJ.com. This personal experience of what he called "just youthful ignorance" is encouraging him to submit a bill (A3583), which, "Prohibits retrofitting diesel-powered vehicles to increase particulate emissions for the purpose of 'coal rolling'; prohibits the practice of 'coal rolling.'" If you're caught violating the law, you would be hit with a fine from the state Department of Environmental Protection. Of course, the Feds say it is already illegal to modify an exhaust system in a way that allows coal rolling. Rolling coal has become a bit of a meme recently, with videos of laughing truck drivers spewing their modified exhaust pipes at green cars, pedestrians and bikers around the country. Eustace told NJ.com that, "People had been telling this has been going on, but I hadn't seen it. I was surprised to experience it myself." Perhaps a coal roller in New Jersey will be surprised, too, when the first big fine hits. News Source: NJ.comImage Credit: YouTube Green Nissan Green Culture Diesel Vehicles rolling coal
