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 Genesis Coupe joins the SEMA fray

With several tuned rides already headed to the show, Hyundai finishes off this year's slate with a mean-looking Genesis Coupe from Tjin Edition painted in a searing shade of green. The coupe's 3.8-liter V6 gets a Vortech supercharger and front-mounted intercooler to help push the claimed output to over 500 horsepower. A set of KW coilovers and Baer brakes also make sure the coupe handles and stops just as well as it accelerates. Tjin's custom shade of lime green paint will draw attention to this Genesis Coupe at Hyundai's booth. Once attendees get closer, they can check out the car's tweaked front lip, trunk lid, and rear spoiler from Unique Fabrication. Meanwhile, the interior mixes performance and comfort by combining a roll cage and Alea leather upholstery. The Tijn Edition Genesis Coupe will join Hyundai's other offerings at this year's SEMA Show in Las Vegas on November 3. TJIN EDITION ROUNDS OUT HYUNDAI'S SEMA LINEUP WITH EXTREME GENESIS COUPE FOUNTAIN VALLEY, Calif., Oct. 26, 2015 – Rounding out Hyundai's 2015 SEMA lineup, TJIN Edition RoadShow has revealed details on its convention-defying Genesis Coupe. For Neil Tjin's first official Hyundai vehicle built for SEMA, the builder turned to underground racing for inspiration to create this mad, 500 horsepower racer. The vehicle will be revealed at Hyundai's SEMA press conference on November 3 at 11:30 a.m. PT. At the heart of TJIN's Genesis Coupe is Hyundai's 3.8-liter "Lambda" V6 engine, which has been boosted via a Vortech supercharger kit built by the power gurus from Bisimoto Engineering. With the addition of a free-flowing exhaust system, Vortech front mount intercooler and blow-off valve, the vehicle now produces more than 500 horsepower. With the addition of Rotiform 19-in. 3-piece HUR wheels, custom Baer x CBA Extreme Plus brake calipers and Falklen FK345 tires, the vehicle's stopping power is now on par with its go-fast performance. The vehicle now sits lower on KW coilovers to give a more aggressive stance. Unique Fabrication supplied a custom front lip, rear spoiler and custom trunk lid, and the exterior was finished in a custom Kylie Tjin Axalta green paint job. "The Tjin Edition Hyundai Genesis is the perfect mix of speed and style," said Neil Tjin, president, TJIN Edition RoadShow.

2014 Hyundai Equus facelift revealed ahead of NY debut

Hyundai has dropped a pair of videos detailing the facelifted 2014 Equus ahead of the luxury sedan's official debut at the New York Auto Show later this month. New adaptive LED headlamps are matched with redesigned LED taillamps, along with new 18-inch alloy wheels at all four corners (19s are optional). Buyers will get to enjoy a card-type smart key and a shift-by-wire gear change indoors. More importantly, the vehicle's forward cabin is now dominated by a 9.2-inch screen mounted in the center of the dash.
The old analog gauges have also gone by the wayside in favor of a new TFT LCD display. Mechanically, the 2014 Equus will continue to offer a standard 3.8-liter V6 engine or an optional 5.0-liter V8, depending on the market (the US-spec car is currently only available with the V8). The vehicle can be configured with a total of three driving modes, including Normal, Snow and Sport, which can adjust multiple systems, including the vehicle's electronic dampers. You can check out two computer-generated videos of the four-door below.
