Piston rings are critical components in an internal combustion engine, fitted around the outer diameter of the piston. They serve three main functions: sealing the combustion chamber, regulating oil consumption, and transferring heat from the piston to the cylinder wall.

Connecting rods are essential components in an internal combustion engine, connecting the piston to the crankshaft. They transfer the force generated during combustion from the piston to the crankshaft, converting linear motion into rotational motion.

An alternator is a key component in a vehicle’s electrical system, responsible for generating electricity to power the engine’s electrical systems and charge the battery while the engine is running. It converts mechanical energy from the engine into electrical energy through the process of electromagnetic induction.

A Wire ECU (Electronic Control Unit) is a critical component in modern electrical systems, especially in vehicles and machinery, where it manages and controls the operation of various electronic functions. It acts as the brain behind complex wiring networks, ensuring communication between sensors, actuators, and control modules.
