Hyundai Motor Group unveils world’s first CVVD engine technology with better performance, less emissions – Lifestyle News

Hyundai Motor Group has developed the world’s first Continuously Variable Valve Duration (CVVD) technology to feature in future Hyundai vehicles.

The innovation was revealed at Hyundai Motorstudio Goyang on Wednesday alongside the Smartstream G1.6 T-GDi the first engine to feature the technology.

CVVD optimizes both engine performance and fuel efficiency while also being eco-friendly.

The valve control technology regulates the duration of valve opening and closing according to driving conditions, achieving a 4% boost in performance and a 5% improvement in fuel efficiency. Furthermore, the technology cuts emissions by 12%.

“The development of the CVVD technology is an opportunity for Hyundai Motor Group to take the lead in powertrain innovation,” said Albert Biermann, President and Head of Research and Development Division at Hyundai Motor Group.

“We will continue our innovation efforts to bring forth paradigm shifts and ensure sustainability of our business model.”

Innovation: Continuously Variable Valve Duration

Until now, an internal combustion engine’s performance and efficiency have been governed by variable valve control technology that adjusts the timing of valve opening and closing and depth of the valve’s opening, with engine power produced through the fuel intake-compression-expansion-exhaustion cycle.

Typical variable valve control technologies manage the timing of the valve’s opening and closing (as in Continuously Variable Valve Timing – CVVT) or control the volume of air admitted by adjusting the depth of the opening (Continuously Variable Valve Lift – CVVL).

. variable valve control technologies could not regulate valve duration, as the valve’s closing timing was subordinate to opening timing and could not respond to diverse driving situations. CVVD takes the technology in a new direction by adjusting how long a valve is open.

When the vehicle is maintaining a constant speed and requires low engine output, CVVD opens the intake valve from the middle to end of the compression stroke.

This helps to improve fuel efficiency by reducing the resistance caused by compression.

On the other hand, when engine output is high, such as when the car is driving at a high speed, the intake valve is closed at the beginning of the compression stroke to maximize the amount of air used for the explosion, enhancing torque to improve acceleration.

Smartstream G1.6 T-GDi Engine

Unveiled alongside the new CVVD technology is the new Smartstream G1.6 T-GDi Engine, a V4 gasoline turbo unit with 180 horsepower and 27.0kgm of torque.

The new powertrain is the first to utilize the Group’s new CVVD technology and also features Low-Pressure Exhaust Gas Recirculation (LP EGR) to further optimize fuel efficiency.

The exhaust gas recirculation system returns some of the gas burnt by the engine to the combustion chamber, producing a cooling effect and reducing the emission of nitrogen oxides.

The G1.6 T-GDi also features a low-pressure system that redirects the burnt emission gas to the front of the turbocharger compressor, rather than the intake system, to increase efficiency under the high load condition.

Additionally, the new unit has an Integrated Thermal Management System that quickly heats or cools the engine to an optimal temperature, and a strong direct spray system that achieves 350bar, surpassing the 250bar of the previous T-GDi engine.

In addition, engine friction is reduced by 34% with the application of low friction moving parts.

Femi Fani-Kayode, the controversial former Aviation Minister has shared his opinion on the greatest danger to Nigeria’s stability, peace and unity.  

 

According to him, the greatest danger to Nigeria’s stability is ‘the insolent and rapacious disposition and insatiable lust for power of the Fulani hegemonists coupled with the Fulanisation agenda’,

In his words; The greatest danger to Nigeria’s stability, peace and unity is the insolent and rappacious disposition and insatiable lust for power of the Fulani hegemonists coupled with the Fulanisation and Islamisation agenda of President Muhammadu Buhari.

You cannot possibly comprehend the mindboggling mess that our country is in, let alone get us out of it, until you fully appreciate this fundamental and basic point. For the last 59 years as a nation we have been swimming in one big massive soakaway and the stench is unbearable.
