Honda, GM fuel-cell partnership wants to reduce hydrogen refueling costs

To paraphrase the old political adage, it's the cost, stupid. Dollar signs are what's prompting Honda and General Motors to partner up to accelerate development of a hydrogen fuel cell system. With about half the cost of a fuel-cell system tied up in its fuel-cell stack, GM and Honda are looking to help each other drive costs down, according to a presentation by GM fuel cell research and development director Mark Mathias said in a presentation at the SAE 2014 Hybrid & Electric Vehicle Technologies Symposium. According to Green Car Congress, Honda and GM are looking to reap the fruits of their collective labor by 2020. As with other automakers, the high cost of producing fuel-cell vehicles is the fly in the ointment of a powertrain technology that combines the same range as gas-powered vehicles but with zero emissions. In the meantime, Honda, which makes the very limited production FCX Clarity fuel-cell vehicle, is slated to start selling its own mass-market fuel-cell vehicle in 2015. The two automakers made their partnership announcement last summer and said they contribute to expanding hydrogen fuel infrastructure in California during the next few years. Earlier, Ford, Mercedes-Benz parent Daimler and Nissan also said they would work together to speed up fuel-cell technology development.

Honda 'Hands' ad is a worthy successor to 'Cog'

The 2003 Cog commercial from Honda may have been named one of the best car commercials of all time, but an all-new spot called Hands looks to be even more entertaining even if it's digitally enhanced. The two-minute video - which starts and ends with a nod to Cog - highlights just about all facets of Honda's universe of products from passenger cars to racecars, the HondaJet to leaf blowers, motorcycles, ATVs and even Asimo.
Celebrating 65 years of innovation, the advertisement is as informative as it is amusing, and it even injects a little humor, too, like a glass of water being squeezed from the FCX Clarity. We just hope that the 1:10 mark of the video isn't hinting at a CR-V Convertible. We're not sure when Hands will air or if we'll see it on television here in the US, but the video is posted below; as an added bonus, we've also included the video for Cog.

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.
