Honda adds 4.5 million vehicles to Takata recall, none in North America

The already massive Takata airbag inflator recall is getting 4.5-million units larger across the world. Honda is issuing an expansion to its safety campaign in many foreign markets. Of those newly affected cars, about 1.63 million of them are in Japan. None of these models are in North America. According to Reuters, Honda decided on this recall expansion after analyzing 1,000 inflators from vehicles not previously covered by its campaigns. The company found that the density of the gas-producing chemicals varied in them, which could cause a safety problem in the future. The models affected include foreign versions of the Fit and CR-V with production dates between 2007 and 2011, the Associated Press reports. Research suggests that Takata's inflators can be affected by exposure to moisture. This can cause the propellant to ignite too quickly and the component to shoot metal shrapnel when the airbag deploys. The issue has been linked to eight deaths worldwide, and there was a recent report of the issue causing a vehicle fire in a Nissan in Japan. The global inflator recall has had serious affects on Honda's books, as well. The Japanese automaker recently had to revise earnings from last year to account for an extra $363 million in costs from the campaigns and has been dealing with lawsuits over the issue. To improve quality, the company decided not to set sales goals through at least 2017. Honda last expanded the recall in Japan in late May to cover another 340,000 vehicles. It has also been searching for Takata's inflators in junkyards in the US. Related Video:

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.

Ward's Automotive Ten Best Engines of 2014 dominated by diesels, turbos

With the Car and Driver Ten Best decided, the North American Car and Truck of the Year finalists announced and Cadillac, Ram and Subaru chalking up wins with Motor Trend, it's fair to say that the automotive awards season is in full swing. The next set of trophies to be handed out will be from Ward's Automotive, which has announced the winners of its 2014 10 Best Engines.
The latest contest was marked by the widespread emergence of diesel power and the continued success of turbocharged engines. There was even an electric motor on this year's list. In fact, only three of the ten winners were naturally aspirated and only two winners returned from last year.
"We weren't looking to throw the bums out, as they might say about an election. We were just really impressed with the flood of new powertrains," said Ward's Automotive Editor-in-Chief Drew Winter. Those new powertrains include the 83-kilowatt electric motor from the Fiat 500e, the 1.0-liter, EcoBoost three-cylinder from the Ford Fiesta and the 2.0-liter turbodiesel from the Chevrolet Cruze.
