They slide up and down inside the cylinder, transferring force to the connecting rod. | Typically made of aluminum alloys for their lightweight properties, combined with high-strength steel for critical areas. The piston’s crown is often coated with a hard material like silicon nitride to resist wear. | A piston is a cylindrical component with a flat top (crown) and a smaller diameter at the bottom (skirt). The crown is responsible for sealing the combustion chamber, while the skirt interacts with the cylinder walls. |
| Valves | Valves regulate the flow of intake air and exhaust gases into and out of the combustion chamber. They open and close in response to signals from the camshaft. | Valves are commonly constructed from high-strength steel alloys. The valve stem is typically made from a material that offers both strength and resistance to heat. Valve seats are often made from heat-resistant alloys. | A valve is a component that opens and closes, allowing gas flow into or out of the combustion chamber. It consists of a valve head, valve stem, and valve spring. The valve head is the part that seals the combustion chamber opening, and the valve stem connects to the camshaft. |
| Crankshaft | The crankshaft converts the reciprocating motion of the pistons into rotational motion. It transmits power to the vehicle’s drivetrain. | Crankshafts are often made from forged steel alloys for their strength and durability. The material selection is critical to withstand the high torsional stresses during operation. | A crankshaft is a rotating shaft with a series of crank arms. These crank arms are connected to the connecting rods, which in turn connect to the pistons. The rotational motion of the crankshaft is transferred to the transmission. |
| Connecting Rods | Connecting rods connect the pistons to the crankshaft. They transmit the force generated by the piston to the crankshaft, converting linear motion into rotational motion. | Connecting rods are typically made of forged steel alloys, selected for their high strength-to-weight ratio and resistance to fatigue. | A connecting rod is a component that links the piston to the crankshaft. It has a large bearing surface at each end to allow for smooth rotation and minimize friction. |
| Camshafts | The camshaft controls the opening and closing of the valves in the engine. It has lobes (cams) that push on the valve lifters, causing the valves to open and close at the appropriate times. | Camshafts are typically made from hardened steel alloys, designed to withstand the repeated impacts and stresses. | A camshaft is a rotating shaft with a series of lobes (cams) along its length. These cams push on the valve lifters, controlling the valve opening and closing timing. |
