Engine Block

Basics

• The "Core" of the engine
• Typically used in reference to Internal Combustion Engines (ICEs), but can also be applied to External Combustion Engines (ECEs) if such a block is used, as opposed to independant cylendars
• It holds most of the core components:
  • Acts as the outer part of the cylendars
  • Holds various rods/axles
  • Can even have lines / ports for liquids (is this ever done?)

Production Methods

• Most often:
  • "Blank" is cast, often by Investment Casting (need to see if this is becoming outdated)
  • Blank is Heat Treated (Metalwork)
  • Blank Is Machined (Typically via CNC Mill ) to acheive more precise Tolerances
  • This step may occur at seperate facilities, but:
  • The final holes etc are drilled, and the engine block is finalized (plus any other treatments etc)
