9. Electrical Components in a Car
• Majority of car composed of electrical components
• Air conditioning, in-car technology, relies on electrical
circuits
• Electrical components in a car usually a luxury and is basic
foundation of the vehicle next to the chassis

10. ECU (Engine Control Units)• Older mechanical
ECU’s
• Responsible for
controlling
air/fuel ratio,
ignition and valve
timing, etc.
• Multiple electrical
sensors to
complete tasks

11. Other Critical Components Spark Plugs
Battery
Fuse

12. Overview
• Electrical components are the basic foundation, as
important as the chassis
• Every component is equally as important even though
it might seem useless
• Advancement of cars will rely on humans’
engineering capability to generate and apply
electrical power in diverse ways

13. Chemical Engineering

14. Liquid: Gasoline
• 87, 89, 91-93, Ultra Low Sulfur
Diesel (ULSD)
• 87 Octane – lowest octane,
inexpensive, most popular
• 2 C8H18 + 25 O2 → 16 CO2 + 18
H2O

15. Combustion
Perfect Combustion
• FUEL (hydrocarbons) + AIR (oxygen and nitrogen) = CARBON
DIOXIDE(CO2) + Water (H2O) + Nitrogen
Real World Combustion
• FUEL (hydrocarbons) + AIR (oxygen and nitrogen) = UNBURNED or
PARTIALLY BURNED HYDROCARBONS (VOCs) + NITROGEN
OXIDES(NOx) + CARBON MONOXIDE (CO) + CARBON
DIOXIDE (CO2) + Water (H2O)
HYDROCARBONS (HC)
NITROGEN OXIDES (NOx)
CARBON MONOXIDE (CO)
CARBON DIOXIDE (CO2)

16. Liquid: Coolant
• Requirements for a
Liquid Coolant for
Electronics
• Types of Coolant

17. Liquid: Oil
• Elemental Composition of Petroleum
• Conventional oil
• Full-synthetic oil
• Synthetic-blend oil
