What is the reason for the humming sound when accelerating in Haval H6?
1 Answers
Acceleration with resonance noise is basically caused by low-speed engine resonance. Low-speed vibration frequency is low, and when it is close to or the same as the natural frequency of certain components, resonance occurs. The following is a relevant introduction to the Haval H6: 1. Model Highlights: The Haval H6 is positioned as an urban SUV, with two drive modes: two-wheel drive and four-wheel drive. The H6 is built on a new platform different from the previous H3 and H5, with the main feature being the use of a monocoque body. The four-wheel-drive version of the H6 employs an on-demand four-wheel-drive system, unlike the body-on-frame + part-time four-wheel-drive system used in the H3 and H5. While this may affect its off-road performance to some extent, the benefits include reduced body weight for improved fuel efficiency and better ride comfort. 2. Powertrain: Equipped with a 1.5GDITEVO engine, the maximum torque output range is expanded to 1400-3600 rpm, paired with a second-generation 7DCT transmission, achieving a comprehensive transmission efficiency of up to 95.6%.
