F1 champ Fernando Alonso geared up for rookie run at Indy

NEW YORK - Twice Formula One world champion Fernando Alonso surprised himself with his qualifying success for Sunday's Indianapolis 500, but the Spaniard knows his biggest challenge will come on race day. Alonso, racing on an oval for the first time, averaged more than 230 miles per hour (370 kph) to qualify fifth fastest for a place in the second row in the 33-car field at Indianapolis Motor Speedway. "I was a bit surprised," Alonso, 35, told Reuters on Tuesday. "When we announced to come here one month ago, we did it without knowing how competitive we could be, if I was able to adapt to oval racing, to these cars." "I still lack experience in important moments of the race. I will try to compensate with the speed, with motivation and we will see what happens." A lack of experience may cost him on the biggest day of US racing when a champion will be crowned after 200 laps of the massive 2.5-mile oval, but Alonso is geared up for the chance. "You respect the place, respect the speed. You respect your colleagues out there, but at the end of the day, when you are in your car and close the visor, you would like to have one mile per hour more. It's never enough," he said. While Alonso passed the entrance exam with flying colors in qualifying, he knows the hardest test is to come. "The biggest challenge I will face is in the race when you are running in traffic, those groups of cars that form in the race. It changes completely the behavior of the car. "You feel the car very loose... we've been practicing that with the team, trying to create our own groups because we are six cars," Alonso said. "I still lack experience in important moments of the race. I will try to compensate with the speed, with motivation and we will see what happens." GUESSING GAMES Alonso said timing his moves may be a guessing game. "Taking the opportunity to overtake and to pass will be a difficult decision to make," he said. "There are many factors you need to address while you are driving 230 miles per hour. "You have to stay calm, be ready for the last one-third of the race. That is where it comes." Alonso said the race demands a balance between pushing the limit and not crossing the line into recklessness. "With no experience, for me you're not sure sometimes where you are with that line - if you are over the limits of the car, or over the limits of running with the traffic.

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.

Japanese automakers welcome North American trade deal, fear what's next

TOKYO — Toyota, Nissan and Mazda welcomed on Tuesday the revised North America trade deal that left Japanese automakers unscathed, but they may face a bumpy ride when Washington and Tokyo hold new talks on over $40 billion of annual U.S. auto imports from Japan. The United States and Canada reached an agreement on Sunday to update the 1994 North American Free Trade Agreement after Washington had forged a separate trade deal with Mexico in August. The updated deal effectively maintains the auto industry's current footprint in North America, and spares Canada and Mexico from the prospect of U.S. national security tariffs on their vehicles. Mazda, which ships cars to the United States from Mexico and Japan, called the deal a "big step forward". Nissan, which makes the cars it sells in the United States locally as well as in Mexico, Japan and other countries, said it was "encouraged" by the agreement. Toyota, Japan's biggest automaker, said it was "pleased" that a basic deal was reached. Other automakers were not immediately available for comment. While the deal has removed the risk that the disintegration of the pact would have posed to automakers, bigger risks loom large for Japanese firms as a chunk of the roughly 7 million cars they sold in the U.S. last year were shipped from Japan, and a trade deal between Washington and Tokyo has yet to be agreed. The United States and Japan last week agreed to begin fresh trade talks, with U.S. President Donald Trump seeking to address Japan's $69 billion trade surplus, of which nearly two-thirds comes from auto exports. Washington is also investigating the possibility of slapping 25 percent tariffs on auto imports on national security grounds, although it has agreed with Japan to put any new tariffs on hold during the talks. Analysts say the United States may take a tougher stance on auto imports from Japan than from its neighbors. "If Japan requests an exemption from the 25 percent tariffs under consideration, Washington could propose a more strict cap on imports than it agreed to with Mexico and Canada," said Koji Endo, senior analyst at SBI Securities. "That would be a risk." This could be a big blow to Japan, as the United States is a key source of revenue for Japanese automakers including Toyota, Nissan and Honda. The U.S. market accounts for a quarter or more of their annual global vehicle sales, and of their total U.S.
