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.

2015 Hyundai Sonata confirmed for New York debut

Despite receiving a host of improvements for the 2014 model year, the next-generation Hyundai Sonata is right around the corner. During a technical briefing today, Hyundai's North American CEO, John Krafcik, has confirmed to Autoblog that the 2015 Sonata will debut at the 2014 New York Auto Show in April.
The Sonata will be one of Hyundai's three major launches coming in the first half of 2014. First will be the 2015 Genesis sedan, which will bow at the 2014 Detroit Auto Show, and also coming in 2014 is a new fuel-cell vehicle from Hyundai.
Despite the current Sonata's age relative to key rivals, it's still doing rather well for Hyundai. Krafcik told us that the sedan currently has a 42-day dealer supply, which is lower than its fresher competitors. The nipped/tucked 2014 Sonata should help keep that momentum going until this all-new 2015 model arrives next year.

Hyundai, Kia ratchet up fleet sales as retail transactions slide

Automotive News reports both Hyundai and Kia have stepped up fleet sales in an attempt to offset disappointing first quarter results. The Korean automakers saw their sales decline by nine percent compared to last year, while all major competitors managed to increase their sales. That situation marks an inversion of two years ago, when both gained ground after Japanese rivals suffered production and inventory shortages after the country's earthquake and tsunami tragedies.
Now, Hyundai can't come up with enough volume models in popular trim configurations to satisfy buyers, and lower-volume models are also in a snag. At the moment, Hyundai can only build 20-30 percent of Veloster hatchbacks with turbocharged engines while the US market would apparently support closer to 70 percent.
In order to reverse the sales slide, Hyundai and Kia have stepped up fleet sales of the vehicles they do have by some 50 percent, ringing up a total of 42,400 units in the first quarter. By contrast, Automotive News reports the seven largest automakers increased retail volume by seven percent and fleet sales by four percent as a group.
