Study Notes

Engine Oil

  • Function: Lubricates engine components, reduces friction, and prevents overheating
  • Types:
    • Conventional (petroleum-based)
    • Synthetic (chemical-based)
    • Synthetic blend (mix of conventional and synthetic)
  • Viscosity: Measures oil's thickness and flowability
    • Thin oils for cold weather, thick oils for hot weather
  • Additives:
    • Detergents: Neutralize acids and remove deposits
    • Dispersants: Prevent soot and varnish buildup
    • Anti-wear agents: Reduce friction and wear

Transmission Fluid

  • Function: Lubricates transmission components, reduces friction, and prevents overheating
  • Types:
    • Automatic transmission fluid (ATF)
    • Manual transmission fluid (MTF)
    • Continuously variable transmission fluid (CVTF)
  • Properties:
    • Viscosity: Similar to engine oil, but with higher viscosity index
    • Friction modifiers: Reduce clutch pack wear and improve shifting
    • Anti-wear agents: Prevent gear and bearing wear

Filtration Systems

  • Function: Remove contaminants from lubricants to prevent engine damage
  • Types:
    • Oil filters: Remove particles, soot, and varnish from engine oil
    • Fuel filters: Remove particles and contaminants from fuel
    • Air filters: Remove particles and contaminants from air
  • Filter types:
    • Cartridge-style filters
    • Canister-style filters
    • Synthetic media filters

Coolant System

  • Function: Regulates engine temperature and prevents overheating
  • Components:
    • Radiator: Heat exchanger that dissipates heat
    • Water pump: Circulates coolant through the system
    • Hoses: Transport coolant between components
    • Thermostat: Regulates engine temperature
  • Coolant types:
    • Ethylene glycol-based
    • Propylene glycol-based
    • Organic acid technology (OAT) coolants

Engine Oil

  • Lubricates engine components, reduces friction, and prevents overheating
  • Comes in three types: conventional, synthetic, and synthetic blend
  • Viscosity measures oil's thickness and flowability, with thin oils for cold weather and thick oils for hot weather
  • Additives include detergents to neutralize acids, dispersants to prevent soot buildup, and anti-wear agents to reduce friction

Transmission Fluid

  • Lubricates transmission components, reduces friction, and prevents overheating
  • Comes in three types: automatic transmission fluid (ATF), manual transmission fluid (MTF), and continuously variable transmission fluid (CVTF)
  • Has a higher viscosity index than engine oil, with friction modifiers to reduce clutch pack wear and anti-wear agents to prevent gear wear

Filtration Systems

  • Remove contaminants from lubricants to prevent engine damage
  • Includes oil filters to remove particles and varnish, fuel filters to remove particles, and air filters to remove particles
  • Filter types include cartridge-style, canister-style, and synthetic media filters

Coolant System

  • Regulates engine temperature and prevents overheating
  • Components include radiators, water pumps, hoses, and thermostats
  • Coolants come in three types: ethylene glycol-based, propylene glycol-based, and organic acid technology (OAT) coolants
