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.

Hyundai: Ryanville

Ryanville is a commercial about a town full of Ryan Reynolds clones, and two smitten women driving around in a brand new Elantra who can't help but gawk at the actor because he's everywhere. This is a great ad if you like Ryan Reynolds, as these two women (and many other people) do. Hyundai also wants to remind you that if you're distracted by Ryan Reynolds, the Elantra's active Automatic Emergency Braking with Pedestrian Detection will help prevent you from running his handsome clone over. Vote for this one if you like the commercial, Ryan Reynolds, or both. Marketing/Advertising Hyundai Super Bowl Commercials 2016 super bowl ad

Hyundai Veloster nixed in UK after just 3 years

The Veloster, Hyundai's funky, four-door hatchback, has been pulled from the British market after just three years on sale. The blame, as is usually the case in these circumstances, is being placed on slow sales. Auto Express reports that, much like it has in the United States, the Veloster has failed to resonate with both customers and critics. While UK sales figures weren't available to prove AE's point, Veloster sales in the US through November are down nearly 2,000 units over the same period in 2013, to under 26,000 vehicles. That makes it the third-slowest seller in the Hyundai lineup, behind the far more expensive Azera and Equus sedans. The performance-minded Veloster Turbo will be replaced in the UK by a version of the i30 equipped with the VT's 1.6-liter, force-induced, direct-injected engine.
