What does DVVT engine mean?

DVVT engine stands for Dual Variable Valve Timing, which refers to the variable valve timing technology for both intake and exhaust. Below is more information about DVVT engines: 1. The DVVT engine is an extension and development of VVT, addressing technical challenges that VVT engines could not overcome. 2. DVVT, or Dual Variable Valve Timing, can be considered the most advanced form of variable valve timing system technology currently available.
DVVT engine refers to the Dual Variable Valve Timing system. I've studied this technology myself, and simply put, it uses a hydraulic control device to simultaneously adjust the opening and closing times of both intake and exhaust valves. At low engine speeds, such as in traffic jams, it delays the closing of the intake valve to allow more air into the cylinder, improving torque. At high speeds, like when driving on highways, it closes the intake valve earlier to enhance explosive power. The advantage of this design is that it avoids the low-speed weakness of traditional engines while also optimizing fuel consumption. It also automatically adjusts its strategy based on factors like water temperature or load, making it smarter and more environmentally friendly compared to single VVT systems that only control the intake valve. Modern family cars, such as some Japanese brands, use this solution.
