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.

IED Torino students dream up the PassoCorto for Hyundai

Every year the students at the Istituto Europeo di Design (IED) in Turin work up something new to unveil at the Geneva Motor Show. It's usually a concept for an Italian automaker (like the Alfa Romeo Gloria, the Cisitalia 202 E or the Abarth ScorpION) or at least something European (like the concepts they worked up with McLaren or the ones they did for Aston Martin). But this time they've wandered a little farther from home in designing a sports car for Hyundai.
It's called the PassoCorto - Italian for "short wheelbase" - and it was designed in collaboration between the grad students in the Master in Transportation Design program (under the supervision of Pininfarina design Luca Borgogno) and the Hyundai's European design center.
The design (theoretically) calls for a 1.6-liter twin-turbo four, mounted amidships and driving 266 horsepower to the rear wheels. It looks pretty promising, and if Hyundai were ever keen on taking on the likes of the Alfa Romeo 4C and Porsche Cayman, this strikes us as a damn good place to start.

Hyundai recalls about 980,000 Sonatas for seat belt detachments

The Basics: Hyundai is recalling 977,778 Hyundai Sonatas and Sonata Hybrids for seat belts that could detach from their anchor pretensioners, which could lead to an injury. The recall affects 2010- cars including 2011-2014 standard Sonatas built from December 11, 2009 to May 29, 2014 and 2011-2015 Sonata Hybrids built from December 2, 2010 to January 9, 2015. The Problem: During manufacturing, some Sonatas may not have had the seat belt properly attached to the anchor pretensioner. According to NHTSA recall information, the seat belt is connected to the anchor after the latter has been installed, and it is possible that the seat belt didn't completely latch onto the anchor during assembly. If the seat belt was not properly attached, it can separate from the anchor during a collision, potentially leading to an injury. Injuries/Deaths: Hyundai has reported one injury to NHTSA. No deaths related to the recall have been reported. The Fix: Owners are asked to bring in their vehicles to dealerships to have the seat belt assembly inspected to make sure the belt is correctly latched. If not, the dealer will reattach it properly at no cost to the owner. If you own one: Hyundai will alert owners to the recall by mail starting April 7. Owners can also call Hyundai's customer service directly to ask about the recall at 1-855-371-9460. They can also enter their VINs at the NHTSA website to check if their car is included in the recall. Related Video:
