Before the close of 2019, Hyundai car users will get to experience first-hand the latest engine technology that the Korean carmaker calls the Continuously Variable Valve Duration or CVVD, which is set to hit the road through the Smartstream G1.6 T-GDi engine. The cutting edge tech is designed to increase performance and cut down on emission at the same time, the company said.
Hyundai said CVVD would make Smartstream engines, which will be deployed in upcoming Hyundai and Kia car models, truly eco-friendly as the tech will boost engine power and fuel efficiency simultaneously. Per the projections offered by Hyundai engineers, CVVD will drive up performance by four percent while efficiency is seen to improve by five percent.
And the best part, the engine tech at optimal use will reduce emissions by up to 12 percent. The projections, according to CNET, are nothing short of impressive in an era where "modern engines are already squeezing out as much performance and efficiency as possible."
"The development of the CVVD technology is a good example how Hyundai Motor Group is strengthening our powertrain technology ... We will continue our innovation efforts to bring forth paradigm shifts and ensure sustainability of our business model," Hyundai said in a press release.
The CVVD magic primarily works this way: the tech extends the time that the engine valve stays open or more specifically, the intake valve is opened up during the middle and end of the compression stroke. In this behavior, the compression resistance is significantly reduced and is more evident when driving at a constant speed.
Hyundai said that with CVVD, a driver gets to achieve the supreme amount of available air by simply stepping on the pedal. This will prompt the intake valve to close at the start of the cylinder's compression stroke and maximize the air required for the explosion in order to enhance the torque and improve acceleration. And the result is increased engine performance that cannot be found on other engine systems.
This latest innovation from Hyundai will provide optimal flexibility in relation to the driving style or condition that is currently in effect.
The company intends to introduce CVVD commercially via the Smartstream engine line that will be in use first with the Hyundai Sonata Turbo model. Under the hood of this car model is a motor engine beefed up by a 1.6-liter turbocharged I4 with 180 horsepower and 195 pound-feet of torque.
The Sonata Turbo is slated to roll out in the second half of 2019, and according to Hyundai, there will be more car models with the CVVD engine tech to follow suit, bearing the Hyundai and Kia brand names.
