1. By: Jared Eischeid Compression or Spark?

2. WHERE DOES IT COME FROM? Gas and diesel fuel are both refined from crude oil also known as petroleum refining 3 simple steps Separation- heated to boiling point to separate hydrocarbons Conversion-changing certain hydrocarbons into another Treatment-adding processed products to meat emission laws

3. SAME THING OR DIFFERENT? Both are internal combustion motors designed to convert chemical energy into mechanical Gas- fuel is mixed with air, compressed by pistons, and ignited by spark plugs (spark) Diesel- air is compressed before fuel is injected, compressed air ignites when heated (compression)

5. WHAT IS BETTER? Diesel Emit small amounts of carbon monoxide, hydrocarbons, and carbon dioxide Have greatly reduced soot levels and noise levels Cost more but get higher fuel mileage Last longer and higher energy density

6. ECONOMY Construction equipment Semis, trains, and freight ships Military and agricultural equipment Essential for todays living and already dominates over gasoline in Europe
