					Diesel Engine

• Rudolf Diesel
• German nationality,
  but born in Paris in
• Wanted to become
  an engineer at the
  age of 14
• Against the will of
  his parents
        Rudolf Diesel
• Went to Royal Bavarian Polytechnic
  of Munich
• He began to design an engine based
  on the Carnot cycle and formed the
  basis for his invention of the diesel
Later Life
 He knew that even very good steam
  engines are only 10-15%
  thermodynamically efficient, which means
  that up to 90% of energy available in the
  fuel is wasted
 His goal was to increase the efficiency
 He tried to design an engine based on the
  Carnot cycle, but he failed
 He developed his own engine according to
  his theory and design
 It was later called the diesel engine
             Diesel Engine
 A diesel engine is an internal combustion
  engine that uses the heat of compression
  to initiate ignition to burn the fuel, which is
  injected into the combustion chamber
  during the final stage of compression
 It is developed in 1897
              How does it work?
   It converts the chemical energy available in fuel
    into mechanical energy
   This mechanical energy moves pistons up and
    down inside cylinders
   This motion creates the rotary motion needed to
    turn the wheels of a car forward
   It uses a four stroke combustion cycle: intake,
    compression, combustion, and exhaust
Diesel Engine and the Industrial Revolution

 It delivers power more efficiently, thus
  less expensively, for a variety of industries
  all over the world
 It did not require burning coal, train
  transport and shipping companies were
  able to save a great deal of money
      Diesel Engine and society
   Diesel engines have long been popular in
    bigger cars, and it is spreading to smaller
   It is more economical
   It is also used in trains by replacing steam
