2015 Honda Fit recalled over ignition coils

Honda is issuing a recall for 17,800 units of the 2015 Fit in the US because they have faulty ignition coils. According to the automaker, the parts can degrade over time, potentially leading to the engine stalling. The company discovered the issue from warranty claims outside of the US. Currently, there are no reported crashes or injuries related to this problem. Owners will start receiving official notification of the recall on October 6. As usual, the repair will be done at no charge for affected owners. Related Video: Statement by American Honda Regarding Plug Top Ignition Coil Recall: 2015 Honda Fit Sep 2, 2015 - TORRANCE, Calif. Honda will voluntarily recall approximately 17,800 model-year 2015 Fit vehicles in the United States to replace the plug top ignition coils, free of charge. The original plug top ignition coils may degrade over time, which, in the worst case, could cause the vehicle's engine to stall, potentially increasing the risk of a crash. No crashes or injuries have been reported related to this issue, which was discovered through the warranty claim process outside of the United States. Honda is announcing this recall to encourage each owner of an affected vehicle to take it to an authorized dealer as soon as they receive notification of this recall from Honda. Mailed notification to customers will begin October 6, 2015. Additionally, owners of these vehicles can determine if their vehicles require repair now by going to www.recalls.honda.com or by calling (888) 234-2138.

NSX Concept-GT is the world's hottest way to boil water

The Honda NSX Concept-GT is one sexy machine, and it looks to be a very effective tool on a race circuit. But Honda's latest web spot leads us to believe that it also can be used to make tea.
In the video, the racecar is hooked up to an apparatus that uses tubing to harness the energy from the car's 500-horsepower hybrid drive system, using it to boil water. The novel tea-making technique reminds us a bit of a couple other inventive Honda commercials, namely Hands and Cog.
Watch the NSX ad below, and be sure to turn the sound up to hear that glorious engine note.

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.
