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.

Superman-themed Kia Optima Hybrid definitely not faster than a speeding bullet

The Justice League of America's garage is filling up quickly, with Kia and DC Entertainment unveiling its sixth of eight super hero-inspired vehicles at the Chicago Auto Show today. The vehicles are being used to raise awareness for DC Entertainment's "We Can Be Heroes" giving campaign.
The latest Kia to get the super hero treatment is the Optima Hybrid, which draws on the almighty Superman for inspiration. We're not sure what to make of this thing, honestly, as neither Clark Kent nor Kal-El would be caught dead in it (unless it's got the optional Kryptonite seatbelts, of course). Rather, this looks like what we imagine a Superman fanboy would construct if given carte blanche to ruin an Optima Hybrid. The actual design and construction were handled jointly by Kia, DC Entertainment and Super Street magazine.
We'll let the pictures do the talking in terms of what modifications were made since they're all cosmetic. That is, no mechanical mods were done to make the Kia Optima either faster than a speeding bullet or more powerful than a locomotive (shame).

Hyundai-Kia dealer offers $180k in gift cards to local residents

In many smaller communities, auto dealers are often major players in the local business and political world, and they interact with large portions of the population. Now, Grand West Hyundai and Grand West Kia in Grand Junction, CO, are putting their marketing dollars to work in a way to help the local economy, while also potentially generating some sales at the same time. Over the next six months, the dealers are contacting about 8,000 previous customers and offering them a gift card worth at least $50 to over 100 of the city's shops and restaurants (pictured above), according to Automotive News. All people need to do to receive the certificate is stop by the showrooms. Hopefully, the visitors would check out a new Hyundai or Kia at the same time. "We'd love to sell them a new car, but it is really a customer-appreciation gesture," said Ken Reeher, the dealers' marketing manager, to Automotive News. The two stores already bought about 3,600 cards with $181,000 going into the local economy. Paying people to come to the showroom isn't really new but generally works well. The Colorado dealers expect around half of the people they contact to visit for the gift card, which is still significantly more foot traffic than from traditional mailings. The decision to keep the cards local also means more money goes to small businesses, and the move gains goodwill in the community, too.
