Engine Anatomy (Engine Internal Structure Analysis) The Global trade tender evaluation toolsengine is a complex machine that can convert the energy generated by fuel combustion into mechanical energy, thus driving the vehicle to rotate. From the outside, the engine looks like a neat iron box, but it contains many sophisticated mechanical and electronic components inside. In this article, the internal structure of the engine will be dissected in detail. I. Several structures of gasoline engines. Gasoline engines have various structural forms, such as single-cylinder, twin-cylinder, four-cylinder, six-cylinder, eight-cylinder or even twelve-cylinder. Among them, most passenger and commercial vehicles use four-cylinder engines.There is a piston, a piston ring, a connecting rod and a crankshaft inside each cylinder block. The piston and the crankshaft are connected by a connecting rod, and the crankshaft rotates through the force of fuel combustion, and finally drives the wheels. II. The internal structure of the gasoline engine 1. The cylinder block and cylinder head of the engine constitute the main structure of the engine. The cylinder block is a vertical ring seen from the side, and the inside is the working space of the piston and connecting rod. The cylinder head is a cover covering the top of the cylinder block, including the valve, spark plug, intake duct, outlet duct and other components. Additional accessories on the cylinder head also include intake and exhaust convexity.The drive chamber of the camshaft, and the camshaft is supported by a series of sliding bearings through sleepers or other means. Two. The crankshaft and connecting rod The crankshaft and connecting rod constitute the power transmission system of the engine. A crankshaft is a long, iron, cylindrical camshaft located at the bottom of the engine, parallel to the axle. The angle and curve shape of the crankshaft can convert the front and rear reciprocating motion of each cylinder into rotational motion. Each connecting rod converts the linear motion of the piston into the rotational motion of the crankshaft. 3. The valve and piston valve are the main components of the engine, and they are installed on the cylinder head at the top of the cylinder block. The opening and closing time of the valve is controlled by the camshaft. The piston works opposite to the valve, and the piston works in this mode: injecting mixed gas when going down and discharging exhaust gas when rising.Four. The motion transmission and motion transmission systems of the axle engine include transmission, transmission shaft and transmission system. These parts transmit the rotation movement to the wheels. Wheels are composed of hubs, tires and axles. The engine powers the wheels in this way, thus driving the car forward. Conclusion The engine is the heart of a car, which is composed of various sophisticated parts. Understanding the internal structure of the engine can help us better maintain and understand our cars. Whether you are a car enthusiast or a car repairman, an in-depth understanding of the engine is very important. The above is the basic structure of engine anatomy. I hope it will be helpful for your study.
