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
