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-Kia fuel-economy errors trigger $300M in federal penalties [w/video]

This amount includes $100-million in civil penalties, the largest such fines in EPA history.
Hyundai and Kia are getting more than a slap on the wrist for overstating the fuel economy of an estimated 1.2-million vehicles in their 2011-2013 model ranges. The Environmental Protection Agency, the Department of Justice and the California Air Resources Board are hitting the automakers with collective penalties valued at around $300 million for Clean Air Act violations. This amount includes $100-million in civil penalties, the largest such fines in EPA history. Specifically, Hyundai is paying a $56.8 million penalty and relinquishing 2.7-million greenhouse gas emissions credits. Kia is paying $43.2 million in penalties and giving up 2.05-million credits.

Hyundai partners with tech startup Smartcar to expand mobility apps

A new technology partnership between Hyundai and a Silicon Valley startup will expand the automaker's connected-car service offerings on its 2018 model-year vehicles, making it possible for owners to do everything from getting their car washed and detailed to fueling up, all without having to actually be there for it. Hyundai announced the partnership with technology startup Smartcar (not to be confused with the automaker) at the L.A. Auto Show to launch its Blue Link All-Access program. The platform aims to give Hyundai owners access to a broad array of new third-party connected-car applications, similar to how users download apps for mobile devices, by giving Smartcar access to its API. That means the automaker can offer new services more quickly, since it won't have to do a separate new integration for every new connected-car service, said Manish Mehrotra, Hyundai Motor America's director of digital business planning and connected operations. "We will develop Blue Link not as standalone system, but as an open platform that can seamlessly integrate the best ideas from inside and outside the company," Mehrotra said. App developers will work with Smartcar, based in Mountain View, Calif., as the single point of integration. Hyundai's Blue Link platform already had allowed owners to do things like sync addresses from their phones to their in-vehicle navigation systems via voice command, start and warm up the car remotely, and locate the vehicle when the driver forgets where he parked it. The new service will be offered on every 2018 model-year Hyundai free of charge for the first three years of ownership. Hyundai also announced a new pilot program in Southern California with an Orange County startup called Washos, which offers mobile car washing and detailing. Other time-saving existing or future applications include being able to get your dry cleaning or groceries delivered to your car while at work. Because the future is going to be BUSY. As further evidence of what he called "our deepening relationships with the technology community," Mehrotra also discussed the recent launch of Cradle, Hyundai's new venture-capital arm.
