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.

Henrik Fisker interview, and driving the Polestar 2 | Autoblog Podcast #643

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder. They've been driving the updated 2021 Honda Odyssey, the 2020 Mercedes-AMG GLC 43 and the new Polestar 2 electric sedan. After reviewing those, they talk about how the Chrysler 300 appears to be withering on the vine. Next, they take time to talk to legendary automotive designer and eponymous Chairman & CEO of Fisker Inc., Mr. Henrik Fisker himself, about jeans, horses and, of course, electric cars. Finally, they help a listener pick a $100,000 supercar in the "Spend My Money" segment.

Mom Accidentally Steals Honda In Brooklyn

The owner of a 1993 Honda Accord that was accidentally stolen by a young Brooklyn woman's mother has the car back in her possession, after amusing posters popped up all over town. Cheryl Thorpe traveled to New York from her home in Houston to watch her daughter's dog while she and her roommates went on vacation, according to New York Magazine. Thorpe was also left the task of moving the three girls' cars to legal parking spots on a street-cleaning day. She dutifully moved the Fiat, Honda CR-V and Accord, but when the trio returned from their vacation something was wrong. The owner of the Accord found her car right where she left it, thankfully free of parking tickets. The Accord Thorpe had moved belonged to someone else. As it turns out, some older Hondas have interchangeable keys. Thorpe was able to use the girl's keys to move Emily Hickert's car while she ate brunch. Hickert spent an entire week thinking a professional car thief had made off with her 21-year-old ride. "In less than 40 seconds she gets in the car and goes," Hickert told The New York Post, after reviewing security footage from a nearby business. "I thought she was a professional." Hickert filed a police report, while Thorpe's daughter posted fliers all over Brooklyn looking for the Accord's owner. Hickert was eventually reunited with her Honda, which had been towed after sitting parked on the street. She says she bears no ill will towards the women involved in the mix up. "I'm not upset with her," Hickert told The Post. "I'm glad it wasn't a thief. I just didn't know why anyone would steal a 1993 Honda."
