Transcript of Engine Island!
Mike Xiao, Roderick Stokes Engine Island! Overview How Crude Oil is Refined
Crude oil is extracted from wells
Comprised of hydrocarbon variations
plant & animal fossil remains
Different molecular arrangements result in boiling point nuances.
Chemical processing - shortens hydrocarbon length
Fractional distillation - boils crude oil https://docs.google.com/document/d/1yEQ3yvu32SiSDBBx8Ifbx8zhbrfVFWfm442oUjq1lBE/edit?usp=sharing Here's the link to the script document Visual Representation of

Extracting the Oil Oil Extraction Components How is Crude Oil Refined
Future of Engines G== Part 3: Gasoline Engines Gas Engines: A history The Function of Gasoline Engines FAQ Part: 5
Diesel Composition Part Six: Diesel Engines !VIDEO VOLCANO! Part: 5 The Future of Internal Combustion Engines HISTORY OF DIESEL ENGINE i) Invented by Rudolph Diesel ii) Patented in 1892 iii) Prevalent use throughout history and
today What is a Spark Plug? I) An insulated plug composed of the following parts:
(2) Porcelain or alumina insulator
(5) Secondary Coil
(6) Center Electrode How Does a Spark Plug Work? i) Magnet on a spinning flywheel.
ii) This current generates the electrical energy needed.
iii) Secondary coil
iv) Ignition i) Operates very similarly to the Gas Engine. Called a four stroke engine because it involves four movements, or strokes. How Diesel Engines Work ii) Cycle: What Could Go Wrong? i) Ignition too early
ii) Ignition too late
iii) Gap is not set properly
iv) Carbon build-up 2. Compression stroke The Future of Spark Plugs 3. Combustion stroke i) Pulse Plugs 4. Exhaust strokes i) Early Conceptions:
Abu Al-Jazari, 1206 ii) Patenting:
Samuel Brown, 1823 iii) Modern day use Diesel Engine Vs. Gas Engine i) The diesel engine is more energy efficient, 25-30% better fuel economy ii) Fuel is injected into compressed air, allowing high compression ratio without knocking i) Four-stroke cycle ii) A cylinder lies in the core of the engine iii) Glow plugs iii) Arrangement Problems with gas engines
i) While in America we seldom drive diesel cars, diesel accounts for 50% of the auto market in Europe
ii) Diesel cars can run on biodiesel without any engine modifications
iii) Newer CRT particulate filters and catalytic converters as well as better refined diesel fuel can reduce soot, CO, particulate matter and hydrocarbons emission by as much as 90% in the future i) Bad Fuel Mix ii) Lack of compression iii) Lack of spark i) Diesel is made from fractional distillation of petroleum
ii) More viscous, oil like consistency. Has a higher boiling point than water
iii) Releases 13% more CO2 than petrol when burned
iv) energy content of 38.6 MJ/L i) Are there any advantages to steam engines over combustion engines? ii) Are there any other cycles besides the four stroke cycle? iii) Why have multiple cylinders, and not just one huge one?
iv) Why do you need to jump start your car when the battery dies out? The future is looking pretty bleak for IC engines.
Source of sustainability until presented with an alternative wh'ale be finished soon! Pay attention kids, Main components of gasoline: Isooctane butane 3-ethyltoluene Gas or Petrol: Made from fractional distillation of petroleum Energy content: 34.6 MJ/L Chemical Composition of Gasoline ii) Lasers Chemical Composition of Diesel 1.
