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 Project 2&4 concept has 212 hp, 893 lbs, and our hearts

Take one look at the Honda Project 2&4 concept, and it's immediately clear that the minimalist track special is the result of a collaboration between automotive and motorcycle designers. The body's styling is a modernized take on the Japanese brand's RA272 Formula One car from the 1960s, but then you notice the weird driver's seat that's fully exposed and suspended just inches above the road. The result is a vehicle that looks absolutely deadly, but like an absurd thrill to pilot, too. The Project 2&4's floating seating design simultaneously evokes both a sport bike and a go-kart. There's no dashboard or windshield at all, and the driver simply gets a steering wheel and a glass panel for the instruments. It's hard to imagine pairing things down much more than this, especially since the whole vehicle weighs just 893 pounds. The concept's other major piece of motorcycle DNA is the mid-mounted 1.0-liter V4 sourced from Honda's RC213V that races in MotoGP. Tuned here for road use, it puts down over 212 horsepower when spinning at 13,000 rpm, and peak torque of 87 pound-feet hits at a still stellar 10,500 rpm. The redline is at a stratospheric 14,000 rpm. The high-revving engine bangs through the gears through a six-speed dual clutch transmission. Unfortunately, the Project 2&4 has zero provisions for even a modicum of driver safety, and that makes it exceedingly unlikely for one to ever see customer orders. We still look forward to seeing that bizarre, floating seat on display at the 2015 Frankfurt Motor Show, though. HONDA PROJECT 2&4 POWERED BY RC213V TO DEBUT AT FRANKFURT: A COMBINATION OF GLOBAL CREATIVITY AND CRAFTSMANSHIP Winner of Honda's 'Global Design Project' to debut at the Frankfurt Motor Show Cabin-less structure features a floating seat design for immersive driving experience Powered by Honda's MotoGP RC213V engine, modified to run on public roads 'Honda Project 2&4 powered by RC213V', the winning entry from Honda's 'Global Design Project', will make its global debut at the 66th Frankfurt Motor Show at stand B11 in Hall 9.0. Embodying the concept of 'creative craftsmanship', Honda Project 2&4 celebrates Honda's position as the world's leading engine manufacturer, providing engines to 28 million people per year across two- and four-wheel automotive, power equipment, marine and aerospace applications.
