Daimler, Toyota, BMW to lead $10-billion hydrogen investment

Daimler, BMW, and Toyota are leading a group of 13 companies pledging to invest more than $10 billion during the next five years to spur enough infrastructure-building and technology advancements to get more of the general public to buy hydrogen fuel-cell vehicles. The automakers, which also include Honda and Hyundai, as well as companies such as Shell, AirLiquide, Linde Group, and Total SA, are part of what they're calling the Hydrogen Council. The group made its announcement in Davos, Switzerland, on Tuesday. The Hydrogen Council will pledge to accelerate its rate of hydrogen-related investments, which currently stand at about $1.5 billion annually. The coalition says its work represents a continuation of the 2015 Paris Agreement, in which many of the companies agreed to address the issue of climate change. The group says that hydrogen, which emits water vapor when used in fuel-cell vehicles, "can play an important role in the transition to a clean, low-carbon, energy system." The Hydrogen Council also vowed to push global governments to accelerate public investment in hydrogen-related infrastructure. Relative to other drivetrain technologies, hydrogen fuel-cell vehicles are in their relative infancy in terms of adoption because of the high cost of both building fuel cell vehicles and setting up a hydrogen-refueling infrastructure. Toyota is the only automaker that sells a production fuel-cell vehicle in the US. The Japanese company, which introduced its Mirai domestically in late 2015, sold 1,034 of them in the US last year. Daimler subsidiary, Mercedes-Benz, used Tuesday's announcement to remind people that it would start selling its GLC plug-in hydrogen fuel-cell crossover this year. There are only 33 publicly accessible hydrogen refueling stations in the US, including 30 in California, and one each in Connecticut, Massachusetts, and South Carolina, according to the US Department of Energy. By comparison, there are more than 15,000 electric-vehicle charging stations with almost 40,000 outlets in the US.

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.

NHTSA Probes Nearly 400,000 Infiniti, Honda Vehicles Over Steering Faults

As many as 391,000 vehicles from Honda and Infiniti may eventually need to be recalled as a result of two, separately announced Preliminary Evaluations from the National Highway Traffic Safety Administration to ascertain the scope of the potential safety hazards. In one of the queries, NHTSA is looking into 24 reports from drivers of the 2013 Honda Accord who say they had total loss of their power steering or experienced a sudden increase in the necessary effort to turn the wheel. In four cases, the problem may be linked to crashes. According to the claims, 13 people reported seeing a warning message during the failure. Turning off the car and restarting it would fix the issue in some cases. If a recall is necessary, it could affect an estimated 374,000 Accords. The second investigation is much smaller in scope. The safety agency is investigating the 2008 Infiniti EX35 after two complaints of the steering wheel shaft separating and the vehicle losing the ability to steer. Both reports say the steering became loose when driving and then completely failed once the vehicle was stopped. A recall for the problem would affect an estimated 17,000 vehicles.
