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 Blue Link Android smartwatch app will start your car

We knew Hyundai would be bringing its Blue Link smartwatch app to the Consumer Electronics Show, and now that CES is upon us, the app's workings have been revealed. Once you get the free Blue Link app on your smartphone and your Android smartwatch and pair them up with the app, it's all systems go. Through either touch or voice commands, you can remotely lock or unlock your car doors, start and stop your engine, flash the lights and honk the horn, or have your watch locate your car. It works on every Hyundai with first- or second-gen Blue Link (which is all of them in the case of first-gen and the 2015 Genesis, Sonata and Azera for second-gen). The watch app isn't quite ready yet, but the company says you'll be able to get it sometime in Q1. There's a video above showing Hyundai's offering at work, and a press release below with more information below. HYUNDAI BLUE LINK TO DEBUT SMARTWATCH APP WITH VOICE RECOGNITION AT 2015 CONSUMER ELECTRONICS SHOW AND PEPCOM'S DIGITAL EXPERIENCE - Next Generation Blue Link System to Launch on 2016 Elantra GT and Veloster - The Blue Link smartwatch app works with first and second generation Blue Link equipped Hyundai models Fountain Valley, Calif., Jan. 2, 2015 – Smartwatch sales are skyrocketing and starting early in 2015 Hyundai owners will be able to connect with their cars using these wearable devices and the Hyundai Blue Link® smartwatch app. Hyundai will debut and demonstrate the Blue Link smartwatch app at Pepcom's Digital Experience and at the Consumer Electronics Show (CES®). Pepcom's Digital Experience takes place before CES on Jan. 5 and Hyundai's exhibit (North Hall, booth #2818) at CES will be open Jan. 6-9, 2015. Hyundai's cloud-based Blue Link platform allows features like remote start and service information to be quickly accessed through devices like smartwatches and smartphones. Hyundai partnered with Station Digital Media to develop the Blue Link smartwatch app. "This new app expands Hyundai's exploration into how wearable technology and Blue Link fit into a customer's lifestyle," said Barry Ratzlaff, executive director, customer connect and service business development, Hyundai Motor America. "Connecting to your car through a smartwatch and voice recognition was previously something seen only in science fiction movies. Now, we can provide this capability to owners of Hyundai vehicles equipped with Blue Link." The app is easy to use.

Hyundai's second Super Bowl ad is a Nice piece of work

Yesterday, Hyundai unveiled its Dad's Sixth Sense Super Bowl ad, which showed off the 2015 Genesis Sedan and its auto emergency braking system. While a fine spot, it lacked the pizzaz we expect of a commercial for the big game. Hyundai's second half-minute commercial, however, is more of what we expect of a Super Bowl ad.
Starring The Big Bang Theory's Johnny Galecki and with a cameo from comedian Richard Lewis, the commercial sees Galecki trying to woo a woman he comes across at a stop light by complimenting her on her Elantra, which just so happens to be what he's driving. Things go hilariously awry from there.
Scroll down for a full look at the video, and let us know how you think it stacks up next to yesterday's Dad's video.
