The piston, which receives high heat and great force as the mixture combusts and expands, acts as a guide for reciprocating motion and cools the cylinder appropriately to firmly support the crankshaft.

It forms a combustion space so that the high-pressure gas and air mixture can ignite and burn accurately. Additionally, the cylinder head functions as a seal to maintain pressure generated within the cylinder and prevent leakage to the outside.

It is a horizontal structure installed to secure overall rigidity and stability by connecting the left and right structures of the vehicle.

A part that fixes the stator and supports the bearing part of the rotor in the motor body, preventing harmful substances such as foreign matter, dust, and water from entering the motor, while extending the life of the motor and shortening assembly time. .A part that fixes the stator and supports the bearing part of the rotor in the motor body, preventing harmful substances such as foreign matter, dust, and water from entering the motor, while extending the life of the motor and shortening assembly time. .
