Inline Functions in C++
Inline functions instruct the compiler to insert the function’s code directly where it’s called, avoiding the overhead of a regular function call. This can improve execution speed, especially for small, frequently called functions.
Purpose
The primary goal of inline functions is to eliminate the overhead associated with function calls, such as saving registers, pushing arguments to the stack, and jumping to the function’s location.
Performance
Inlining enhances performance for

Polyethylene (PE)
Repeating Chemical Structural Unit:
Pf: 110-137 ยบ C
Types of Polyethylene:
- Low Density (LDPE): Branched chain structure.
- Low degree of crystallinity, density, and strength.
- High Density Polyethylene (HDPE): Straight chain structure.
- High degree of crystallinity and resistance.
- Linear Low Density (LLDPE): Linear structure with short, oblique lateral branches.
Properties:
- Low cost.
- Toughness and low ambient temperature resistance.
- Good flexibility.
- Excellent corrosion resistance.
Engine Components and Lubrication Systems
1. Engine Block and Cylinder Liners
Engine blocks are typically made of cast iron or light alloy. Cast iron, made from flake graphite, offers good mechanical strength but is heavy. Aluminum alloy, composed of silicon, is lighter. Cylinder liners, often made of cast iron, provide a wear-resistant surface within the engine block.
Types of Cylinders
- Integral Block: The cylinder is directly machined into the engine block material, without separate liners.
- Dry Liner: Thin-walled cylinders are press-fitted
