Takata airbag victim looked like she had been stabbed

We generally take certain principals for granted. The more water you drink, for example, the healthier you'll be. The more time you spend reading car news on Autoblog, the better informed you'll be. And the more airbags your car has, the safer you'll be. Because airbags equal safety. But that's not what some unfortunate drivers of vehicles equipped with Takata airbags are finding, and tragically finding out the hard way.
In what could be the most startling incident resulting from the airbag debacle so far, a woman named Hien Tran of Orlando, FL, was killed by what looked at first like stab wounds on her neck. It later emerged that the fatal injuries could have been inflicted by the faulty airbag on her Honda Accord. Tran bought her Honda secondhand, and may not have been aware that the airbag issue had not been addressed by its previous owner in a previous recall in 2009.
The Orange County Sheriff's Department is investigating the death, but it wouldn't be the only injury resulting from the malfunctioning Takata airbags. The units, employed particularly by Japanese automakers like Honda (which owns part of Takata) and Toyota, are the subject of a massive recall involving some 14 million vehicles from 11 different automakers.

It turns out Takata isn't willing to expand airbag recall nationally after all

There have been "approximately 0.000006 failures per air bag deployment, which is far below the failure rate" of most recalls, Takata claims. Takata has seemingly made an about face following reports that it would expand its regional airbag recall into a nationwide repair effort, issuing a scathing, four-page letter rebutting allegations by the National Highway Traffic Safety Administration and its Office of Defects while simultaneously attacking the government's handling of the situation. The Japanese supplier claims in its letter that the "currently available, reliable information does not support a nationwide determination of a safety defect," arguing that there were "approximately 0.000006 failures per air bag deployment, which is far below the failure rate in the vast majority of the thousands of recalls," The Detroit News reports. Takata then breaks down the two specific incidents mentioned in NHTSA's original recall request letter, a 2005 Honda Accord and 2007 Ford Mustang. Referencing the two crashes, NHTSA Administrator David Friedman said last month "one incident is an anomaly, but two are a trend." The supplier, though, argues the Honda issue is already being covered by that company's soon-to-be-national recall (more on that in a moment). The company then goes on to point out that neither Takata nor NHTSA has been able to analyze the Mustang's airbag inflator, saying that such a lack of examination meant there was "no way to ascertain what actually occurred during the incident, whether any inflator ruptured, and whether any inflator rupture that may have occurred was related to the incidents that led to the current regional campaigns." Takata alleges that NHTSA has disobeyed its own statutes. Takata also took the opportunity to take a few swipes at NHTSA's behavior during the airbag scandal, saying it was "very surprised to receive" a recall request letter because the ODI had yet to even receive the company's responses to a pair of special orders. It also alleged that NHTSA was disobeying its own statute, which says only manufacturers of vehicles and replacement equipment can "decide in good faith whether their products contain a safety related defect," and that the government can only "issue an initial decision that a safety-related defect exists" to those same entities.

Honda patents engine with different cylinder displacements

A basic rule of engine design states that the displacement of a cylinder is equal to the engine's total displacement divided by its cylinder count. Honda, according to a recently surfaced Japanese patent, is looking to break that rule with an engine containing cylinders of different sizes. We've done our best to translate it from patent-ese. The idea is that different-sized combustion chambers give more flexibility when any combination of cylinders are deactivated, or rested. Because the different numbers can be combined in various ways, it provides more and smaller increments than would an engine with equal-displacement cylinders. Take a 2.0-liter four-cylinder, for example. Following the golden displacement rule, each of the four cylinders has a volume of 500 cc, giving displacement increments of 500 cc when any cylinder is deactivated. But suppose instead that the four cylinders displace 300, 425, 600, and 675 cc, respectively. This would give the engine 15 available displacements instead of just four, and the spacing between each option would be far less than 500cc. As a result, those different virtual displacements would provide more adjustment between power and efficiency than a cylinder-deactivation system can on a conventional engine. Honda's patent describes cylinders with equal bore size, with the displacement from cylinder to cylinder varying based on the crank throw radius – the longer the throw, the longer the stroke and the larger the displacement of that particular combustion chamber. The patent describes how the cylinder sizes would need to be arranged to spread the load on the crankshaft and presumably limit vibration that would be introduced by the different pulse magnitudes. If we're interpreting things correctly, the largest cylinder (the one with the longest crank throw radius) sits in the middle of the bank with the smaller ones alternating on either side as they decrease in displacement. This concept is described for multi-cylinder inline and V-type engines of various sizes. The patent was filed in March of 2014 and published in January of this year. Whether or not this arrangement will reach production is of course unknown, but the advantages in terms of both efficiency and power seem promising.
