Does a Bored Engine Have the Same Power as Before?
1 Answers
Bored engines do not have the same power as before; in most cases, vehicle power is reduced after boring. Reasons for reduced vehicle power after boring: The inner wall of the cylinder after boring is certainly not as smooth as the original factory finish. When the piston is compressed, the combustible mixture may leak, affecting cylinder pressure drop and vehicle power performance. After boring, the cylinder diameter increases, and larger pistons are required, which in turn increases the combustion chamber volume and reduces cylinder pressure. Main effects of a bored engine: After boring, the distance between the original cylinders becomes narrower, reducing the overall strength of the engine block. The inner wall of the cylinder is not as smooth as the original factory finish, leading to reduced piston sealing during compression, which affects vehicle power output. The cylinder diameter after boring is undoubtedly larger than the original, necessitating larger pistons. A larger cylinder diameter means the vehicle's displacement will increase, and fuel consumption will also rise. Reasons for not directly replacing the cylinder liner when boring an engine: The main reason is that the cylinder block of automotive engines is typically a cast iron block without a cylinder liner. When faced with internal cylinder roundness issues, boring is the only solution, as such cast iron blocks without cylinder liners cannot be fitted with them.
