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.

2019 Hyundai Veloster Turbo caught uncovered at video shoot

Here's the fully revealed Hyundai Veloster Turbo, and it appears to be moving pretty quickly based on the blur in the photos. That's understandable because our spy photographer got these shots during a video shoot of the Hyundai's latest hatchback in which it was probably being driven aggressively for good footage. Despite the blur, we can tell quite a bit from the images. First off, we know it's a Turbo model because of its large, round, center exhaust tips. We can also see that the Veloster is hopping on the contrast roof bandwagon, but at least to this editor's eye, the design seems well-suited to the paint scheme. The roof line itself also looks as though it drops down more drastically than the previous model. The rear window is notably wider than the old model, and the slimmer, wider taillights are flush with the glass. We're focusing more on the tail since we already got a good look at the front of the Veloster when Hyundai released official images of the car in snazzy multi-colored camouflage. The car's frown does look more pronounced in a single color, though. It seems the Turbo version also gets a small additional intake inlet in the bottom of the front bumper compared with the normal version. We expect to see the fully uncovered car in person at the 2018 Detroit Auto Show. It will likely appear alongside the less-powerful version. There's also an N version in the works, but it's possible Hyundai won't reveal that until later in the year. Related Video:

Hyundai Sonata PHEV on sale for $34,600, in some states, at least

Hyundai's first plug-in hybrid vehicle is now available in ten US states, and the even better news is that the car can go the equivalent of a marathon, plus a little change, without using a drop of gas. The South Korean automaker says the vehicle will have a 600-mile driving range and will be able to go 27 miles on electric power alone. Other goodies on the safety front include a blind-spot detection system and rear cross-traffic alerts. The sedan pairs a 2.0-liter gas-powered engine and electric motor that combine for 202 horsepower. The car also delivers an estimated 99 miles per gallon equivalent fuel-economy rating. The model's 9.8-kWh battery is five times the size as the one in the Sonata Hybrid. Exactly how well these cars will sell could be a mystery for a little while, as Hyundai and its sister company Kia have steadfastly refused to disclose hybrid-sales figures and this policy might continue with the PHEV. The Sonata PHEV starts at $34,600 before a potential federal-government incentive worth up to $4,919 kicks in. A "limited" trim runs for $4,000 more. The car, whose specifications were largely detailed last month, will be available for sale in California, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Rhode Island and Vermont. The reason for this limited roll-out, Hyundai executives have said, is that those states have the best charging infrastructure network for PHEVs. No word on when the rest of the country will be able to easily buy the sedan, though folks in the other 40 states can at least put in special orders for the car.
