What technology is used in the automatic Premium engine?
2 Answers
Automatic Premium engine adopts DVVT technology, which is the Dual Variable Valve Timing technology, making the engine more efficient, energy-saving, and environmentally friendly. The following is an introduction to the engine with DVVT technology: 1. It utilizes a relatively simple hydraulic cam system to achieve its function. By adjusting the timing of valve closure according to the engine's different working states, it enhances the engine's power performance and improves fuel economy. 2. VVT engines can only adjust the intake valves, while DVVT engines can adjust both intake and exhaust valves simultaneously. They exhibit excellent characteristics of high torque at low RPM and high power at high RPM, making them technologically advanced. 3. By controlling the valves for intake and exhaust timing, this technology is increasingly being applied in modern passenger cars.
I've driven quite a few cars equipped with automatic Premium engines and found they incorporate advanced technologies to enhance performance. Primarily, they feature direct fuel injection systems that allow gasoline to burn more completely, reducing waste. They also come with turbochargers that provide extra power during acceleration, making the drive exhilarating. Additionally, they are equipped with variable valve timing technology, which automatically adjusts the valve opening and closing times based on driving conditions, improving fuel efficiency—typically resulting in significantly lower overall fuel consumption. From my personal experience, the start-up is quiet and smooth, especially when paired with an automatic transmission, making the overall performance quite intelligent. Long-term maintenance is relatively straightforward, though it's important to pay attention to fuel quality and avoid using substandard gasoline that could affect the fuel injection system.
