Honda To Expand Takata Air Bag Recall Nationwide

Under pressure from federal regulators, Honda is expanding a recall of driver's side air bags to all 50 states. The air bags, made by Japanese supplier Takata Corp., can explode with too much force, sending metal shrapnel into the passenger compartment. Takata insists that current recalls covering 8 million U.S. cars in high-humidity areas are sufficient. But the National Highway Traffic Safety Administration wants the recalls expanded nationwide after some incidents outside the high-humidity zones. Rick Schosteck, Honda's executive vice president for North America, told House lawmakers Wednesday that Honda will expand the regional recall it began in June, but will continue to prioritize high-humidity areas. He also said Honda is working with other air bag manufacturers to make sure it has enough parts. Related Gallery Consumer Reports Least Loved Cars 2014 Recalls Honda Safety NHTSA list

Five bikes from EICMA you need to know about

Each and every year, the world's biggest motorcycle manufacturers gather together in Milan, Italy to show off the latest and greatest machinery that will soon be offered to dealerships the world over. It's called EICMA (Esposizione Internazionale Ciclo Motociclo e Accessori), and this year's crop of new motorcycles is just as exciting as ever.
We've selected five of the coolest motorcycles shown at this week's show, including models from Aprilia, BMW, Ducati, Honda and Yamaha. Join us down below for a high-performance, two-wheeled Italian journey.

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.
