Structure of a Gasoline Engine?

Gasoline engine structure consists of two major mechanisms and five systems, namely the crank-connecting rod mechanism, valve train, fuel supply system, lubrication system, cooling system, ignition system, and starting system. Below are the details: Specific meaning: A gasoline engine (Gasoline-Engine) is an engine that uses gasoline as fuel to convert internal energy into kinetic energy. Due to the low viscosity and fast evaporation of gasoline, a fuel injection system can be used to inject gasoline into the cylinder. After compression reaches a certain temperature and pressure, a spark plug ignites it, causing the gas to expand and perform work. Characteristics: Gasoline engines are characterized by high speed, simple structure, light weight, low cost, smooth operation, and convenient maintenance. Gasoline engines are widely used in automobiles, especially in small cars.
The structure of gasoline engines is quite fascinating. I've studied some mechanical devices before. Simply put, the core consists of components like cylinders, pistons, and crankshafts forming the main framework. The cylinder is like a tube, with the piston moving up and down inside, driving the connecting rod linked to the crankshaft to convert linear motion into rotational power. The intake and exhaust valves control gas flow, the fuel injector sprays gasoline in, and the spark plug ignites the mixture to push the piston. Lubrication and cooling systems are essential, such as the oil pump circulating oil to maintain smooth operation and the water pump dissipating heat to prevent overheating. The engine block is divided into the cylinder block and head, also connected to the intake manifold, exhaust manifold, etc., functioning like a heart to drive the vehicle. V-type or inline layouts affect space efficiency, but the basic principles are similar, with modern models focusing more on lightweight materials to reduce weight.
As an ordinary person who has driven for several years, I often pay attention to the internal workings of gasoline engines. The cylinder is the main stage, where pistons move back and forth like legs taking steps, and the connecting rods link to the crankshaft to generate driving force. Every time I press the accelerator, gasoline is injected into the cylinder through the fuel injector, and the spark plug ignites it, causing a small explosion that transfers power to the wheels. There are also intake and exhaust valves controlling the flow of air in and exhaust gases out, while lubricating oil covers every corner to prevent friction damage. The cooling system circulates water to dissipate heat, and poor heat dissipation occurs if it gets clogged. The engine has a compact structure, with the cylinder block supporting all components, and the spark plugs mounted on the cylinder head. These parts work together seamlessly. Occasionally, I check the fluids when parked, and keeping all components clean is crucial to avoid carbon buildup or oil leaks.
