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.

2016 Honda Pilot packs more of everything

Honda has come a long way over the course of its history, evolving from motorcycles to automobiles, marine engines, power equipment, robots and even jet aircraft. But its biggest push over the past couple of decades has been in crossovers and SUVs. From the Passport that was rebadged from the Isuzu Rodeo in the early 90s, Honda's high-riding lineup has expanded to include the CR-V, the smaller HR-V, the oddball Crosstour, the soon-to-be-updated Ridgeline pickup, a smattering of luxury crossovers from Acura, and this, the biggest of them all, the Pilot. And Honda has just revealed an all-new version here at the Chicago Auto Show. Now in its third generation, the all-new 2016 Honda Pilot is, like its predecessors, a three-row family-hauler. Compared to the decidedly boxy model it replaces, the new Pilot is certainly more dynamically styled to more closely match the latest crossovers in the Honda lineup, but it may start to resemble the Odyssey minivan (with which it shares its underpinnings) too closely for some tastes. The new Pilot is three inches longer than the model it replaces, primarily to the benefit of cargo space: Honda says you can now fit a full-size 82-quart cooler in the back without infringing on the third row of seats – ingress and egress from which are now enabled by a power folding second row that opens a wider aperture to the back to more easily fit in all eight passengers. (That is, unless you go for the available second-row bucket seats that reduce capacity to seven.) Interior amenities are increased all around, with a proliferation of power outlets and connectivity ports and an available panoramic roof. Despite the growth, though, the new Pilot is 300 pounds lighter than the model it replaces. It is also built on a more solid platform, to the benefit of handling, crashworthiness and NVH insulation. Of course the new Pilot benefits from all the latest safety and driver-assist systems, and Honda anticipates top ratings from both the National Highway Safety Administration and the Insurance Institute for Highway Safety. Power comes from a 3.5-liter V6 with all the tricks in the book (short of a hybrid assist) to make it as economical as possible. The i-VTEC engine has direct injection, cylinder deactivation, stop/start ignition and an automatic transmission with either six or (for the first time from Honda) nine speeds, depending on the trim level. Buyers will also be able to choose between front- or all-wheel drive.

Honda reveals updated rest-of-world Civic hatchback

The rest of the world's most recent Honda Civic was introduced for 2012, and it looks much the same as the 2014 model Honda will release in January to European and Asian markets. In fact, not much has changed, but a retuned power steering system, revised front and rear damping rates and rear wheel toe and camber adjustments are touted to make the hatchback drive better, World Car Fans reports.
There are some small visual changes, such as privacy glass for the lower rear window, a piano-black front bumper that previously was dark gray and piano-black trim replacing body-color pieces around the license plate area, tailgate and lower bumper. Inside, white stitching adorns the seats, steering wheel and knee pad along with aluminum and gloss-black accents placed around the center console area.
Of course, Honda won't be exporting this particular Civic to the US (or the recently unveiled Civic Tourer), so check out the photo gallery to see it in all its not-for-you glory.
