hyundai engine variable valve timing

Hyundai Motor Group announces a brand new, innovative engine technology that answers the increasing global demand for efficiency and cleaner emissions.

In the International Powertrain Conference in Korea, the South Korean carmaker displays 4 engines (1.6L gasoline and diesel) and 2 transmission types, which embodies the future of Hyundai cars.

The engine is called Smart Stream, and its main proponent is the all-new Continuously Variable Valve Duration (CVVD) technology. As its name suggest, this system works by controlling the timing of the valve opening and closing to meet accelerator inputs from the driver. In short, the engine responds whether you wanted a relaxed stroll or a fast-paced run.

Sounds familiar? Well, Toyota has something similar called Variable Valve Timing with intelligence (VVT-i) and works the same, more or less. Hyundai’s approach might be different; we sure do hope so as they claim that this is the first commercial application of CVVD technology.

What really took our interest is Hyundai’s use of smaller and lighter engine components. In combination with advanced combustion techniques, they claim that the Smart Stream engines can maximize thermal efficiency by 50% — now we’re talking.

Hyundai also reveals its new 8-speed wet dual-clutch transmission (DCT). As most probably know by now, DCTs eliminate the loss of torque from shifting, which in turn optimizes shift response for better acceleration.

The all-new Smart Stream powertrain technology is bound to power all Hyundai vehicles eventually. When exactly? Well, Hyundai didn’t disclose an exact date and what car but the South Korean marque aims to release an all-new Smart Stream engine lineup by 2022. This will consist of 10 gasoline and 6 diesel mills, as well as 6 transmission types.
