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 recalls 2016 Pilot for warning light issue, 35k affected

Honda is recalling 35,406 examples of the 2016 Pilot in the US because the vehicles' warning lamps might not activate immediately. Specifically, the campaign covers two-whee-drive models with build dates between May 4, 2015, and September 8, 2015, and four-wheel drive versions from between May 7, 2015, and September 4, 2015. Due to this issue, if there's a malfunction in aids like the tire pressure monitoring system, anti-lock brakes, or electronic stability control, the corresponding warning light might not immediately illuminate on the instrument panel. When the ignition is turned off and then back on, the alerts do appear. Still, the fault puts the Pilot out of compliance with federal rules. Beginning November 27, the fix will simply be updated instrument cluster software for the affected Pilots. According to documents submitted to the National Highway Traffic Safety Administration (PDF): "As of October 8, 2015, Honda has not received any warranty claims, field reports, injuries or crashes related to this issue."

SUMMARY: Honda (American Honda Motor Co.) is recalling certain model year 2016 Honda Pilot 2WD vehicles manufactured May 4, 2015, to September 8, 2015 and 2016 Pilot 4WD vehicles manufactured May 7, 2015 to September 4, 2015. In the affected vehicles, when one of the safety systems such as tire pressure monitoring, anti-lock braking or electronic stability control malfunctions, there is potential that the instrument panel will not illuminate the corresponding warning light, however the warning lamps will illuminate when the ignition is turned off and then turned back on. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic stability control systems", number 135, "Light vehicle brake systems" and number 138, "Tire pressure monitoring systems". CONSEQUENCE: If a safety system cannot immediately warn the driver when needed, the driver may be at at increased risk of a crash. REMEDY: Honda will notify owners, and dealers will update the instrument cluster software, free of charge.

1997 Acura Integra Type R auctioned for $63,800

The Acura Integra, also known as the Honda Integra, was a front-wheel-drive sport compact car that neatly slotted between the Honda Civic and the Honda Accord. The Integra's sportiness wasn't just in its design, as there were a number of quite powerful engine choices for it, and some handling improvements. The mid-to-late-1990s second-generation car was available as the nearly-200-horsepower Type R version, which made a lasting impression no matter if you were an Acura customer, a Honda customer, a British motoring journalist putting the car through its paces in Wales or a PlayStation Gran Turismo gamer driving a virtual Integra at a fictional race track. The bug-eyed, sharply detailed Integra Type R, complete with a strengthened chassis, lightened spec, white wheels and a sizable rear wing, was an instant classic, and two decades later their values are definitely on the rise. No wonder, as they've been called the best-handling front-wheel-drive cars made, and there's some strong competition for that title. However, while the Integra Type R was sold new in limited numbers (just 320 units for the U.S. market in 1997), it wasn't envisioned just how much they could be worth in 2018. The past weekend, a certain high point was reached, as a 1,200-mile, Championship White, Acura-badged example was sold at a Barrett-Jackson auction for an eye-watering $63,800 with fees included. That is roughly double what the car cost new, no matter how new-condition it is. Perhaps the $60K+ sale price for the Type R was foreboded by a particular Florida-based car selling for $40,750 in late June, on Bring a Trailer. That car wasn't even in as-new condition, as it had already accumulated almost 60,000 miles. While these prices might reflect in the values of other used Integra Type R cars and even the more regular-issue, 170-horsepower Integra GS-R models, it might turn out be a blessing for the existing examples not ravaged by road salt or modding in usual Honda fashion, or stolen and parted out: As the values for Type R's keep climbing, it provides even more of an incentive for Type R owners to keep their cars in good or excellent shape. We're just hoping for a sweet spot there, so that the Integras won't all be mollycoddled and cocooned for fear of depreciation — these cars need to be used, out on the road with the VTEC singing, nearing 8,500 rpm. That's what they were designed for.
