What are the components of the engine block assembly?

Engine block assembly mainly includes the cylinder block (some with cylinder liners), cylinder head, cylinder gasket, and oil pan. Below is relevant information about the engine block assembly: 1. The engine block assembly serves as the engine's framework, providing the mounting base for the crankshaft connecting rod mechanism, valve train, and major components of various engine systems. 2. It consists of the cylinder head cover, cylinder head, cylinder gasket, cylinder block, and oil pan. 3. The cylinder head is used to seal the top of the cylinder and, together with the piston crown and cylinder wall, forms the combustion chamber. 4. Additionally, the water jackets and oil passages within the cylinder head and block, along with the oil pan, are integral parts of the cooling and lubrication systems, respectively.
I remember once when my old car had engine trouble, the mechanic showed me the engine block assembly after opening the hood. He said the core components include the cylinder head, cylinder block, crankcase, and oil pan. The cylinder head is at the top of the engine, controlling the intake and exhaust valves; the cylinder block is the foundational structure, housing the cylinder liners and coolant passages for heat dissipation; the crankcase encloses the crankshaft at the bottom; and the oil pan is essentially the reservoir for engine oil. If these parts wear out—like a leaking cylinder block or oil pan—the engine can overheat or burn oil, compromising driving safety. That time, my car shook violently due to a failed cylinder head gasket, costing me a repair bill. Now, I regularly check coolant and oil levels every three months to prevent major issues. Proper maintenance of the engine block assembly not only extends engine life but also saves fuel and hassle. Paying attention to the temperature gauge and stopping to check if it runs high is a simple habit for daily driving.
