Hydrogen deal between GM, Honda getting factory real

Honda and General Motors may take their cooperation on hydrogen fuel cell technology to the next level by opening a joint factory to produce the components. If the plan comes to fruition, the two automakers could open the plant by 2025 at the latest. "By cutting costs with General Motors, we hope to increase our FCV production capacity to help achieve the government's goal," and anonymous Honda official told The Asahi Shimbun. The Japanese newspaper didn't specify where the companies might build the factory, but the plant would allow the automakers to share the expensive costs of mass-producing fuel cells. Honda and GM would continue to independently develop the actual vehicles that would use these components. The automakers teamed up in 2013 to split the massive investment that's required to develop fuel cell components. Despite years of research focused on driving costs down, the amount of money required to build a hydrogen car can quickly add up for any company because of the expensive metals that the fuel cell stacks require, and there's the additional expense of creating technology in this still burgeoning field. By sharing common parts, Honda and GM can lower prices through economies of scale. Both automakers continue to move forward with hydrogen vehicles. For example, the Honda Clarity Fuel Cell (pictured above) launches in Japan this year, and it should help the country's goal to have as many FCVs on the road as possible in time for the 2020 Olympics in Tokyo. Meanwhile, GM has a fleet of fuel-cell test vehicles that has driven over 3 million miles.

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.

Sampling toys and tools in the Honda Dream Garage

I have two Hondas in my modest garage. One is a 1972 CB450 that I cherish but rarely ride, the other a 2014 HRR216 mower that my neighbors probably wish I'd use more often. Not quite dream garage material, but I like my trusty Hondas all the same. So I was pretty geeked to visit what Honda calls its Dream Garage. Spoiler alert: There was no actual garage. The various Honda products were spread out over a few acres of private land. And before you ask, no, the HondaJet wasn't in attendance. No confining garage meant I got to try a bunch of this stuff out. Honda makes such a wide variety of products, and so many of them, that it is the number one maker of engines in the world, having built 28 million in 2014. Highlights included a smattering of motorcycles, some rugged side-by-sides, the Uni-Cub assistive mobility device/powered stool, a few boats, Honda's latest cars, and snowblowers. Yep, in Southern California in July. They used damp sawdust for demonstrations, which meant I got to run a giant snowblower in a t-shirt. Watch the video above to see me ride, drive, walk behind, and be assisted by some of Honda's latest gear that isn't a car. Some of my favorites: The Grom. I've wanted to ride one since it came out a couple years back. This miniature motorcycle is hilarious and surprisingly rideable given its 125-cc single, which puts out about eight horsepower. It'll do 45 mph pretty easily, which feels fast on this baby bike. The only thing that takes getting used to is the time required to glance down at the instruments – they're way down there. Otherwise, it's a normal motorcycle with tiny wheels and a tinier engine. Riding the Uni-Cub was another dream experience of mine. It's much more intuitive than a Segway and makes you look slightly less goofy. I felt like I was in an OK Go video. It was neat. One item that didn't make the video is the NM4 you see here: crazy anime-inspired styling, a dual-clutch transmission, and then more crazy styling. The DCT means your left hand and foot get a rest. I still grabbed for the clutch every time I started the bike, though. Old habits and their hard deaths. Honda is also putting a dual-clutch transmission into one of its newest side-by-side offerings, but it was only on display and not available to pilot. I drove one with a traditional auto and another with an automated manual – and paddle shifters!
