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.

Bonkers Honda Vezel headlines Mugen's lineup at Tokyo Auto Salon

Japanese automakers and their tuning divisions have descended upon the Makuhari Messe in Chiba City for the 2014 Tokyo Auto Salon. And for Honda, it's all about Mugen.
Honda's Japanese Domestic Market tuning division brought a series of modified concepts and racing cars to the salon this year, including the CR-Z hybrid touring car it fields in the Super GT series, the SF13 single-seater from the Super Formula series as well as customized versions of the Fit, Odyssey and N-WGN. But the prize for the most outrageous of them all surely goes to the modified Vezel you see above.
Modeled on Honda's new Fit-based crossover, the Mugen Vezel Concept goes further than the versions we've seen until now. It features a bonkers body kit, dual exhaust, brake upgrade, sport suspension, intricate 20-inch alloy wheels and an upgraded interior. It's not for the faint of heart, but if you're feeling still interested, you can check it out in the gallery above, along with the announcement below and the specs on Mugen's website.

Honda recalling 405K vehicles over airbag issue

Honda is in hot water due to an airbag glitch that is causing it to recall 405,400 vehicles. According to the campaign, the supplemental restraints might fire for no apparent reason. 342,000 of the affected vehicles are 2003 and 2004 Odyssey minivans, which gels with a National Highway Traffic Safety Administration investigation we reported on in June.
Joining the Odyssey in the recall is the Acura MDX, with 63,400 units covered from the 2003 model year. Unlike the van, though, the MDX's recall covers Japan and Australia, in addition to the US and Canada. Both vehicles are suffering from an airbag control unit that is prone to malfunction when exposed to electrical noise, a condition that can cause the airbags to deploy without warning. Although no crashes have been reported in such scenarios, there have been some injuries typical of airbag deployment - abrasions and such.
Honda will be mailing recall notices to owners near the end of October, asking them to bring their vehicles into the dealership for installation of an electrical noise filter. The repair will take about an hour and be free of charge. Scroll down for the official announcement from Honda.
