Study Notes

Automotive Engineering

Oil provides 33% of the world's energy and transportation engines account for over 60% of the global daily crude oil consumption.
Passenger vehicles, trucks, and heavy-duty vehicles consume roughly 14 million barrels of crude oil per day in the USA.
The USA imports 62% of its oil, contributing to a daily expenditure of approximately $1 billion for imported oil based on current prices.
Replacing internal combustion engines (ICEs) is considered unreasonable for light-duty vehicles. Instead, research is needed for more fuel-efficient and clean power plants.
1 kg of fuel consumes ~15 kg of air and generates about 3 kg of CO2, contributing significantly to the global annual CO2 production of 37 billion tons.
The International Energy Agency suggests reducing fuel use in road vehicles globally by 30-50% by 2030.
The grand challenge for automotive engineering researchers is to maximize engine efficiency, minimizing emissions, and optimizing tolerance of various fuels.

True or False Statements

Oil provides a quarter of the world's energy: True.
62% of internal consumption is extracted from the USA: False (62% is imported).
High expectations for IC engines to be replaced by cleaner ones: True.
No clear alternative for IC engines in commercial vehicles: True.
Burning 1 kg of fuel consumes >15kg air: False (it consumes ~15kg).
The world's annual CO2 production is 37 billion tons: True.
GHGs will be completely stopped by 2050: False (reduction is targeted)
Introducing new technology will be inexpensive: False (it requires substantial investment).
Maximizing engine efficiency is a primary challenge: True.
Adapting to varied fuels will not be a solution for transportation: False (it's regarded as a key solution/adapatation).
