What does engine head mean?

Engine head refers to the engine. Introduction to the engine: An engine (Engine, motor) is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), electric motors, etc. Structure of the engine: The engine block is the framework that constitutes the engine and serves as the installation base for various mechanisms and systems. It houses all the main components and accessories of the engine, both internally and externally, and bears various loads. Therefore, the engine block must have sufficient strength and rigidity. The engine block group mainly consists of components such as the cylinder block, cylinder liner, cylinder head, and cylinder gasket.
I've been repairing cars for over a decade. The engine head, which is the large cover on top of the car engine, is like the top of a human head. You know, it seals the pistons and cylinders underneath, preventing the combustion gases and oil from leaking out, and also helps with heat dissipation. I've encountered many cases before, such as when the head gasket ages, it can cause oil leaks or coolant mixing into the engine oil, leading to engine overheating. This is no small matter; the gasket or even the entire head needs to be replaced promptly, or the engine could be ruined. I remember one time helping a customer with an inspection and finding cracks on the engine head. It cost several thousand to replace, but the car regained its power immediately after the repair. When driving daily, it's best to regularly check around the engine head for any oil stains. Early prevention can save a lot of money.
As a young car owner, I didn't understand much about the engine head when I first learned to drive, but later my friend explained it to me. It's that upper part of the engine, whose main functions are to keep the cylinders sealed and cooled. Without it, the engine would fall apart like an uncovered pot. Now when I drive, I pay attention to the temperature gauge on the dashboard. If it's overheating, it might be a head issue, like a failed gasket. Once my car emitted white smoke, and the mechanic said the head gasket had failed. Replacing it fixed the problem, costing just a few hundred bucks—not too expensive. I've also realized that keeping the cooling system clean is crucial for extending the head's lifespan. In short, understanding this helps us avoid major breakdowns.
