Build a MOC V8 Blocks to Learn How Engine Works

V8 engine is one of the cylinder arrangements of internal combustion engines. Generally used on mid- to high-end vehicles. The 8 cylinders are arranged in two groups, 4 in each group, arranged in a V shape. It is the most common engine structure in current automobile sports. The principle of the V8 engine is the same as that of other engines. V8 represents the arrangement and number of cylinders in the engine. Commonly used cylinder numbers in automobile engines include 3-cylinder, 4-cylinder, 6-cylinder, 8-cylinder, 10-cylinder, 12-cylinder, etc.

The most common angle in V8 engines is 90°. There are many products of this structure, which have the most ideal ignition and vibration characteristics. Because the V6 engine is derived from the V8 engine, a 90° angle is usually used.

Assembling a MOCV8 engine building block is a good way to observe the engine’s operating rules. The MOC engine is a mechanical device based on MOC building blocks that can simulate the working principle of a real engine. It consists of multiple parts, including cylinders, pistons, connecting rods, crankshafts, etc. When the engine is started, the fuel mixture in the cylinder is ignited, creating an explosive force that pushes the piston downward, which in turn drives the connecting rod and crankshaft to rotate, ultimately driving the mechanical device to operate.

The working principle of the MOC engine can be divided into four steps: intake, compression, combustion and exhaust.
The first is the air intake stage. At this stage, the piston moves downward and the air and fuel mixture in the cylinder enters the cylinder through the intake valve. The intake valve opens when the piston moves downward and closes when the piston moves upward.

Next is the compression stage. During this stage, the piston moves upward, compressing the air and fuel mixture inside the cylinder. During this process, both the intake valve and the exhaust valve are closed.

Then comes the burning phase. During this stage, the igniter ignites the fuel mixture in the cylinder, creating an explosive force that pushes the piston downward. During this process, both the intake valve and the exhaust valve are closed.
The last step is the exhaust stage. At this stage, the piston moves upward, expelling the burned exhaust gas out of the cylinder through the exhaust valve. The exhaust valve opens when the piston moves upward and closes when the piston moves downward.

The principle of the MOC engine is basically the same as that of the real engine, but it differs in details. For example, the MOC engine’s cylinder is square, while the real engine’s cylinder is round. In addition, the crankshaft of the MOC engine is composed of multiple parts, while the crankshaft of the real engine is one entire part.

The principle of MOC engine not only allows children to understand the working principle of the engine, but also cultivates their hands-on ability and creativity. Children can design different types of MOC engines based on their imagination and creativity, thereby improving their mechanical production capabilities and creativity. The principle of the MOC engine is an interesting mechanical device that can simulate the working principle of a real engine. It not only allows children to understand the working principle of the engine, but also develops their hands-on ability and creativity.
