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.

Trump wants a trade deal, but South Korea doesn't want US cars

SEOUL - US auto imports from the likes of General Motors and Ford must become more chic, affordable or fuel-efficient to reap the rewards of President Donald Trump's attempts to renegotiate a trade deal with key ally South Korea, officials and industry experts in Seoul say. Meeting South Korean President Moon Jae-in last week in Washington, Trump said the United States would do more to address trade imbalances with South Korea and create "a fair shake" to sell more cars there, the world's 11th largest auto market. "What we really want to say to the United States is: Make good cars, make cars that Korean consumers like." While imports from automakers including Ford, Chrysler and GM more than doubled last year largely thanks to free trade deal which took effect in 2012, sales account for just 1 percent of a market dominated by more affordable models from local giants Hyundai and affiliate Kia. Imports make up just 15 percent of the overall Korean auto market, and are mainly more luxurious models from German automakers BMW and Daimler AG's Mercedes-Benz, which also benefit from a trade deal with the European Union. "Addressing non-tariff barriers would not fundamentally raise the competitiveness of US cars," a senior Korean government official told Reuters, declining to be identified because of the sensitivity of the subject. "What we really want to say to the United States is: Make good cars, make cars that Korean consumers like." TASTE BARRIER In Korea, US imports are seen as lagging German brands in brand image, sophistication and fuel economy, industry experts say. US imports do have a competitive advantage in electric cars: Tesla Motors' electric vehicles are seen as both environmentally friendly and trendy, while GM has launched a long-range Bolt EV. US Commerce Secretary Wilbur Ross had cited a quota in the current trade deal as an obstacle to boosting imports. The quota allows US automakers to bring in each year 25,000 vehicles that meet US, not necessarily Korean, safety standards. Should GM, for example, decide to bring in more than its quota of one model - the Impala sedans - it would cost up to $75 million to modify the cars to meet Korean safety standards, the company told its local labor union. Asked about non-tariff barriers, a spokesman at GM's Korean unit said removing them could expand the range of models the company can bring in from the United States. No US company, however, has yet to make full use of the quota, industry data shows.

Hyundai swims against the current with new i20 Coupe

Coupefying hatchbacks is all the rage in the European market these days. Its what Opel and Vauxhall did with the latest Astra, and what Renault did with the Mégane, and now Hyundai is preparing to follow a similar formula, only in a smaller form.
While the i30 is the model with which Hyundai competes with the aforementioned Astra and Mégane, to say nothing of the Volkswagen Golf and Ford Focus, it's the smaller i20 - recently introduced in five-door form - which the Korean automaker plans to give the coupe treatment.
Previewed in the teaser image above, the upcoming new i20 Coupe will enter a somewhat shrinking market for three-door superminis. Though the VW Polo, Ford Fiesta, Peugeot 208 and Opel Corsa are still available with three portals, their forms are otherwise no more coupe-like than their five-door counterparts. (Mini has tried a similar approach with its Coupe, and Citroën has forked the C3 five-door and DS3 three-door, but those are decidedly more upscale offerings.) Alongside the Seat Ibiza, Hyundai is one of the few mainstream automakers offering three-door superminis significantly distinguished from its five-door versions.
