It’s a win-win situation to improve efficiency and performance, while reducing emissions.

Many are already writing the end of the internal combustion engine, believing that the powertrain will be able to enjoy the better pastures of automotive history. Automakers continue to invest in engine efficiency and Hyundai announced a new technology. Continuously Variable Valve Durability (CVVD) is Hyundai’s new technology. Hyundai claims that the new technology can increase performance and efficiency by 4%, 5% and 12% respectively. Although these numbers may seem insignificant, even small incremental gains can make a significant difference.

Hyundai’s Future Plans:

Understanding how Hyundai’s CVVD engine technology works is key. You need to understand the controls for engine valves, valve timing and valve lifting. Variable valve lift regulates the amount of air that can be allowed into an engine, while valve timing controls when and how the valve opens or closes during an engine cycle. Hyundai’s system adjusts the time that the valve is left open. This allows the engine’s performance to be optimized for the driving conditions.

CVVD allows the intake valve to remain open during constant-speed driving. It closes it at the end of the compression stroke. This reduces compression resistance, which helps fuel efficiency. The intake valve is closed at the beginning of the compression stroke when the engine output is high, such as when the vehicle travels at high speeds. This maximizes combustion air and increases torque, acceleration, performance, and overall engine efficienc

The new Smartstream engine family will be the first to feature Hyundai’s CVVD system. It’s a turbocharged 1.6-liter four cylinder engine with 180 horsepower and 195 pound feet (264 Newton-meters) torque. In the second half this year, the new mill will be available in the 2020 Hyundai Sonata Turbo. The engine will also be available in a Kia version; however, more information about the Kia with the technology will be released later.
