Honda issues stop sale on 2016 Civic with 2.0-liter engine

Honda has issued a stop sale on the 2016 Civic with the 2.0-liter four-cylinder for a problem that might allegedly lead to engine failure. The company also plans to recall and inspect the examples already with customers. Honda spokesperson Chris Martin tells Autoblog that the issue doesn't affect any Civics with the 1.5-liter turbocharged engine. "While the specific details of this action are still being determined, American Honda has provided preliminary information to the NHTSA and intends to provide more details in a formal notification to NHTSA on Friday, February 5," Martin said. After the National Highway Traffic Safety Administration acknowledges the details, Honda will issue an official statement about the problem. A post on the CivicX forum purports to have a Honda document detailing the fault. Some of the 2.0-liter engines may have missing or miss-set piston pin snap rings, which could cause damage to the pistons and other internal parts. The issue reportedly affects roughly 34,000 examples of the 2016 Civic. If the document from the CivicX forum are accurate, dealers will use a borescope to inspect the pin snap rings on the potentially affected engines. According to the forum, replacement parts are not yet available, and Honda expects to notify customers about the recall in March. Autoblog drove the turbocharged version of the 2016 Civic late in 2015 and came away fairly impressed. We loved the new engine and quiet interior but weren't so enamored with the CVT. In any case, if you're in the market for a new Civic, you may now have one more reason to consider the new turbo mill. Related Video:

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 S660 Kei car makes you want to jump in and drive

We want the Honda S660. In fact, after seeing the freshly debuted production model, it's fair to say the kei roadster has already leapt to the very tip-top of our forbidden fruit list. Considering our newfound love for the tiny two-seater, you, dear reader, are going to have to put up with a lot of S660 content in the coming weeks. First up, we have what's called nori-setsu, or "riding instructions." Honda recruited a pair of gymnasts, who use their talents to slide, creatively, into a mockup of the S660. While the acrobats make it look easy, we imagine the amount of space in the S660 makes slotting into the driver's seat off a pommel horse is somewhat dangerous, hence the padding and mocked-up roadster. Fortunately, when an actual S660 is brought out to play, the gymnast finds a more conventional means of getting behind the wheel. Check out the video.
