Why would an engine knock on a ford fusion?

Answer 1

Engine knocking in a Ford Fusion can occur due to several factors, including low-quality fuel, which can lead to pre-ignition, or an improper air-fuel mixture that causes detonation. Additionally, it could be a sign of carbon buildup in the combustion chamber or worn engine components, such as bearings or pistons. Insufficient engine oil or incorrect timing can also contribute to this issue, requiring prompt attention to prevent further damage. Regular maintenance and using the recommended fuel type can help mitigate these problems.
