What is the structure of a gasoline engine?

[DeJonathan]

Conventional gasoline engines consist of components such as the fuel tank, fuel pump, fuel filter, air filter, carburetor, intake manifold, exhaust manifold, and exhaust muffler. Their function is to mix gasoline and air into an appropriate combustible mixture for delivery into the cylinders for combustion and to expel the exhaust gases generated from the engine. Specific details are as follows: Engine Block: This serves as the assembly base for all engine components. It includes the cylinder head, cylinder block, and lower crankcase (oil pan). The inner walls of the cylinder head and cylinder block together form part of the combustion chamber. Many parts of the engine block also function as components of other systems. Crankshaft Connecting Rod Mechanism: This is the mechanism through which the engine generates and transmits power, converting the linear reciprocating motion of the piston into the rotational motion of the crankshaft to output power. It includes the piston, piston pin, connecting rod, crankshaft with flywheel, and cylinder block.
