Hyundai CVVD engine brings another dimension to valve timing

A new technology from Hyundai Motor Group places another marker on the march to more efficient internal combustion engines. Called Continuously Variable Valve Duration, the innovation permits two options for how long the intake valves remain open during the combustion cycle. The feature adds a third take on valve chicanery, atop variable valve timing that changes when valves open, and variable valve lift that changes how far valves open. Hyundai says the feature returns a 4% improvement in performance, a 5% increase in fuel economy, and lowers emissions by 12%. Hyundai applied for two patents on the valvetrain process in South Korea in 2011 and again in 2015. The altered valve duration in this latest iteration is made possible by two movable arms inside the camshaft. Each arm is anchored at its base to a pin at the center of the camshaft, while the end of each arm extends toward the edge of the camshaft. Changing the position of the pin in the center of the camshaft changes the angle of the arms relative to one another, which moves the camshaft along its mounting rod. Voila, a new intake cam profile that either lengthens or shortens valve overlap.   During low-speed spells at low load, CVVD opens the intake valve from the middle to the end of compression stroke. The weaker detonation isn't a factor at low load, and the reduced friction during compression improves fuel economy. During heavy engine loads, the intake valve closes at the beginning of the compression stroke to maximize the amount of air mixed for detonation, boosting torque. Four additional features enhance the benefits of CVVD. A more powerful direct injection system increases fuel spray pressure from 250 bar to 350 bar. Hyundai doesn't go into details on its Integrated Thermal Management System, but says the ITMS "quickly heats or cools the engine to the optimal temperature." Low-friction components lower overall engine friction by 34 percent. And a low-pressure exhaust gas recirculation layout diverts low-pressure exhaust gas from the traditional EGR route to the turbocharger compressor under high load for better fuel efficiency.   The first engine to boast the new tech is the Smartstream G1.6 T-GDi four-cylinder, which produces 180 horsepower and 195 pound-feet of torque. It will appear in the 2020 Hyundai Sonata Turbo going on sale in South Korea later this year.

How automakers stand to benefit from Iran

The big global news of late is a deal that sees a number of major powers easing some sanctions on Iran in return for the Middle Eastern nation scaling back its nuclear program. This thawing of relations between Iran and the West could have far-reaching impacts in both the near and long term, particularly on the auto industry.
As Bloomberg points out, foreign manufacturers, especially Kia and Peugeot, stand to win big by this short-term easing of sanctions. But the impact of opening up the Iranian market to larger-scale sales cannot be underestimated - Peugeot, for example, sold 457,900 units to Iran in 2011 as spare parts kits alone. Opening the Iranian market could also have a huge impact on the cost of oil, as the country was one of the largest producers in the OPEC consortium before firmer sanctions took effect in 2012. Still, as David Cohen, US undersecretary for terrorism and financial intelligence said, it's "not open season now for business in Iran."
Bloomberg has an excellent report of all the near-term effects an easing of sanctions has across a number of industries. Hop over and give it a look.

Kia's Super Bowl ad parks the Optima in a Walken closet

Kia has a weird marketing strategy to sell the Optima in its Super Bowl commercial titled Walken Closet. The humorous spot stars actor Christopher Walken who appears to live in a closet, and he describes the South Korean brand's midsize sedan as "as the world's most exciting pair of socks." Walken is famous for his unique voice, and he enunciates Kia Optima in this ad like no one else can. The ad markets the Optima as the midsize sedan for customers who want something more exciting from the segment. According to Walken, other vehicles are like beige socks, but the Kia has "pizzazz." Comparing a vehicle to a pair of socks still doesn't get the heart racing, though. You can watch a 90-second version of Walken Closet above. Kia will premiere the 60-second cut during the four quarter of the Super Bowl. CHRISTOPHER WALKEN ADDS "PIZZAZZ" TO KIA MOTORS' SUPER BOWL COMMERCIAL FOR THE ALL-NEW OPTIMA MIDSIZE SEDAN Kia is the First Brand to Utilize a New Technology Solution from Influential That Taps IBM Watson for Influencer Identification as Part of Multifaceted Marketing Campaign Extended cut of "Walken Closet" can be viewed now at YouTube.com/Kia; 60-second broadcast version will debut during the fourth quarter of Super Bowl 50 #AddPizzazz social media campaign includes partnerships with Mobile First influencer platform Influential, social media creator network Niche, and lifestyle apparel brand Stance, to engage creators and generate content across a variety of channels IRVINE, Calif., February 2, 2016 – There's no one quite like Christopher Walken – he is an original. And in Kia Motors America's (KMA) 2016 Super Bowl commercial, the Academy Award-winner employs a colorfully stylish sock to demonstrate how the next generation Optima stands out in the midsize sedan segment filled with entries that look and drive the same. Premiering today on YouTube.com/Kia – and set to air in the fourth quarter of the big game – "Walken Closet" is the centerpiece of Kia's multiplatform campaign spotlighting the all-new 2016 Optima as the vibrant alternative for those searching for more in a vehicle segment whose hallmarks are basic, boring and uninspired. As Walken explains in the spot, "There are two kinds of people in this world. Those who are content to blend in ... then there are those who expect more. They're exciting.
