What is the effect of the Envision's dry dual-clutch transmission?
2 Answers
The effect of the Envision's dry dual-clutch transmission is fast gear shifting and relatively fuel-efficient. The gear shifting time of a dual-clutch transmission is extremely short, even faster than that of a manual transmission, taking less than 0.2 seconds. Below are detailed explanations about automotive clutches: 1. Overview: The automotive clutch is located within the flywheel housing between the engine and the transmission. The output shaft of the clutch serves as the input shaft of the transmission. During vehicle operation, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and the transmission, thereby cutting off or transmitting the engine's power to the transmission. 2. Principle: The driving and driven parts of the clutch transmit torque through friction between contact surfaces, using liquid as a transmission medium, or employing magnetic transmission (electromagnetic clutch). This allows for temporary separation and gradual engagement between the two parts, while permitting mutual rotation during the transmission process.
I've been driving the Envision for a year now, and its dry dual-clutch transmission performs well for city commuting. The gear shifts are super fast, upshifting as soon as I step on the gas, and it's particularly fuel-efficient on the highway, saving about a liter per 100 kilometers. However, in stop-and-go traffic, it can be a bit jerky, feeling like a slight nudge that's not smooth, especially in the summer when the fan noise is loud, and the system seems prone to overheating. I recommend using the S mode or manual mode more often on the highway to clear carbon deposits and avoid excessive wear on the clutch plates. The maintenance manual suggests checking it every 20,000 kilometers. Overall, as a daily commuter, it's fuel-efficient and practical, but you need to get used to that little bit of bumpiness.
