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 sketches boxy crossover concept for Shanghai

In America we may be gearing up for the New York Auto Show, but elsewhere in the world there are other shows on the horizon. Like the Shanghai Motor Show, which will kick off later in April. That's where Honda plans to unveil a new crossover concept. The Japanese automaker isn't saying much about what's new with this concept, except to say that it's been designed specifically for the Chinese market. From this teaser image we can already see that the concept looks decidedly more straight-edged and boxy than the Pilot and CR-V we get over here, striking a form that almost begins to resemble a Kia Soul, but not so much that we'd characterize it at this early stage as a potential successor to the Element. We'll just have to sit tight to find out more, but with the doors in Shanghai set to open to the press on April 20, it won't be too long now. Honda to Exhibit World Premiere of All-new Concept Model at the Auto Shanghai 2015 - Overview of Honda Exhibit - BEIJING, China, March 31, 2015 – Honda Motor (China) Investment Co., Ltd., a wholly-owned Honda subsidiary in China, today announced plans to exhibit the world premiere of an all-new concept model as well as other all-new Honda models at Auto Shanghai 2015 (The 16th International Automobile & Manufacturing Technology Exhibition, press days: April 20-21, 2015, public days: April 22-29, 2015). ?Overview of Honda exhibit Jointly with Guangqi Honda Automobile Co., Ltd. and Dongfeng Honda Automobile Co., Ltd., Honda will exhibit the world premiere of a concept model for a new SUV exclusively developed for the Chinese market.

Honda helps Santa take his sled into the 21st century

If you had put nearly 75 billion miles on your only company car, it would most likely be pleading for retirement in every rickety way it knew how. That's Santa's situation, so St. Nick heads to his not-exactly-local-at-all Honda dealer for a new sled, and the company obliges with a red rider fit for the new millennium. But Honda doesn't try to shoehorn he of the white beard into an Civic on rails. Working from Crayon sketches of safe sleighs and wanting to insure a lengthy stint on Santa's "Nice" list, the Honda reps work up a bespoke offering from a block of clay, but still give it features like a rear-view camera and a cargo bay ejector platform fitted with a parachute. You can see their gift to Santa in the video above. And for some even more far out holiday offerings from Honda, check out their Honda Days videos featuring Skeletor singing a bro hymn to He-Man, G.I. Joe serenading Gem, and Gumby and Pokey singing whatever they can think of. News Source: Honda via YouTube Honda Videos
