Does Opening the Engine Count as a Major Overhaul?
1 Answers
Opening the engine is considered a major overhaul. Below is relevant information: 1. Engine Block: The block serves as the skeleton of the engine, providing the foundation for mounting all its mechanisms and systems. It houses all the main components and accessories of the engine, both internally and externally, and withstands various loads. Therefore, the block must possess sufficient strength and rigidity. The block assembly primarily consists of components such as the cylinder block, cylinder liner, cylinder head, and cylinder gasket. 2. Displacement: Engine displacement is one of the most common parameters of an engine. It represents the total volume of all the cylinders' working capacity, typically measured in liters (L). The working volume of a cylinder refers to the gas volume swept by the piston from top dead center to bottom dead center, also known as single-cylinder displacement, which depends on the cylinder bore and piston stroke.
