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.

Next-generation Kia K900 teased

Introduced for the 2015 model year, the current Kia K900 hasn't been around especially long, but Kia is already on the cusp of launching a second-generation of the full-size flagship sedan. An official reveal date wasn't provided by Kia, but we won't have to wait long to see the fully revealed car. The company said the sedan will go on sale in select markets during the second quarter of 2018. So expect to see it in a few months. In the meantime, Kia released the above teaser image. From what we can tell, the new K900, which was developed by both the Korean and U.S. branches of Kia, will look much leaner and better emphasize the car's rear-drive layout. A major contributor to this is how the base of the A-pillar is much farther away from the front wheels, providing a long nose that highlights the longitudinal engine up front. The trunk is more pronounced than on the current model, further making the car look longer and lower. The headlights should be distinctive with unique LED accents, and they don't sweep back along the fender like the current model, either, making the front look more blunt and tough. We expect the K900 to share its platform with the Genesis G90, just as the current one did with the old Hyundai Equus. That also means it will probably be available with both the twin-turbocharged 3.3-liter V6 and the naturally aspirated 5.0-liter V8 in rear- and all-wheel-drive configurations. Related Video:

Kia: The Perfect Getaway

Former 007 Pierce Brosnan took on a new role for the 2015 Super Bowl, featuring in a spot for the new Kia Sorento. The fifth man to take on James Bond, Brosnan is being pitched a new project, although he doesn't seem to be totally on the same page as the executive that's trying to sell him. Where the actor expects a sniper and a missile launcher, he's confronted by a owl and a moose, respectively. It's a pretty humorous spot, all together. As for the car, you can read all about our first-hand experiences in the new Sorento.
