What does DVVT engine mean? Do you know?
2 Answers
First of all, DVVT stands for: Dual Variable Valve Timing, which means intake and exhaust variable valve timing technology. A DVVT engine is an engine that adopts this technology. Engines work according to the four strokes of intake, compression, power, and exhaust, and traditional valves also strictly open or close according to the timing of these four phases. However, DVVT technology allows the valves to open and close normally at low speeds and delay opening and closing at high speeds to improve volumetric efficiency. Engines equipped with DVVT can reduce intake and exhaust losses, lower fuel consumption, and make the engine more powerful. What does a DVVT engine mean? Have you learned it now?
DVVT stands for Dual Variable Valve Timing technology, which is an engine system that automatically adjusts the opening and closing times of the intake and exhaust valves based on driving conditions. This ingenious design allows the engine to reduce valve lift for fuel savings during low-speed driving and increase valve lift for enhanced power output at high speeds, much like intelligently regulating breathing rhythm. Through years of driving experience, I've found this technology highly practical—it not only reduces fuel consumption by about 10% to 15% for daily commutes but also delivers smoother acceleration with less jerkiness. Many popular car models utilize DVVT or similar technologies, such as Toyota's VVT-i or Honda's i-VTEC. Compared to single variable valve timing, it offers greater precision and simpler maintenance, rarely encountering issues with regular upkeep. The automotive industry consistently promotes such innovations to improve efficiency.
