Honda China struggling with high-end Accord because Chinese covet German cars, too

It's not particularly unusual to see cheap cars in China, or those with designs stolen from foreign competitors, but increasingly the best-selling vehicles there would be very recognizable to just about any auto enthusiast. There appears to be one fact of life whether looking at car buyers in Sacramento, Stuttgart or Shanghai: People who can afford to buy premium cars often look first at the Germans.
Honda recently thought that it could challenge this perceived wisdom by including a premium Accord in the ninth-generation sedan's Chinese launch last year. The market-exclusive version was priced against the Audi A4. The venture failed, miserably.
According to Automotive News China, sales for the new Accord in China are down 37 percent through May of this year. Honda's overall sales are actually up by about 11 percent there on the strength of smaller, less profitable models. However, the company is still off its forecast 19-percent rise.

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.

Honda Walking Assist Device begins US testing at Rehabilitation Institute of Chicago

For years, we've been wondering what implications Honda's Asimo robot could have in the real world, and now we're starting to get a sense of that. Honda announced that it will begin its first US clinical studies of the Walking Assist Device at the Rehabilitation Institute of Chicago in an effort to provided improved mobility for people who have suffered a stroke. While the automotive tie-in here is pretty weak, this is the first time we've heard about this device since it was unveiled back in 2008.
Weighing in at six pounds, Honda's device is fitted to the waist and legs of patients to make it easier to walk, and the 22.2-volt lithium-ion battery provides enough electricity for more than an hour of operation. According to Honda's press release, which is posted below, up to 80 percent of the almost 800,000 stroke victims each year (in the US alone) are afflicted with limited mobility, so a medical aid like this could have a big impact in the real world.
