What causes the Haval H9 to lack power during acceleration?
1 Answers
Haval H9 lacks power during acceleration due to excessive carbon buildup in the engine. During engine operation, unsaturated olefins and gum in the fuel produce a coking-like substance under high temperatures, which absorbs gasoline. This creates a vicious cycle where excessive carbon deposits prevent the intake valves from closing tightly, eventually causing the engine to malfunction. Specific solutions are as follows: 1. Avoid prolonged idling and low-speed driving habits, as well as excessive warm-up periods. 2. Use high-quality fuel. 3. Do not shift gears at low RPMs. 4. During maintenance, clean the throttle body approximately every 20,000 kilometers, and if possible, perform an endoscopic inspection.
