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

Ans:
No

Ques: 2 What Is a B-Tree?


Ans:
The B-tree was invented in 1972 by R. Bayer and E. McCreight, and was designed from the start to create shallow trees for fast disk access. Shallow trees have few �levels�, We have to seek through them fewer times, and therefore they run quickly. Because seeks often require going to disk for the information we need, The performance increase with a shallow tree rather than a deeper
