The engine assembly includes core components such as the cylinder block, cylinder head, and oil pan, as well as a series of electronic accessories such as sensors ECU、 The fuel injection system and oil pump, among other components, together constitute the overall architecture of the engine.
Inside the engine, there are key components such as pistons, connecting rods, crankshafts, camshafts, and valves, which work together to enable the engine to operate normally. However, it should be pointed out that the above is only the tip of the iceberg in engine structure. In fact, a complete engine is composed of tens of thousands of precision components.
The engine is known as the heart of a car, which plays an important role in generating electricity and is an indispensable source of power for normal driving. In most cars, reciprocating piston engines are used, and their working principle is relatively intuitive and easy to understand.
The operation process of the engine can be divided into four strokes: during the intake stroke, the piston descends to suck in the combustible mixture; During the compression stroke, the piston moves upward to compress the combustible mixture; During the power stroke, the spark plug ignites the combustible mixture; After combustion, the thrust generated by the combustible mixture causes the piston to descend, thereby driving the engine to generate power. During the exhaust stroke, the piston rises again and the exhaust valve opens to discharge the exhaust gas generated by combustion from the cylinder.
