  1. Diesel Engines By: Douglas Aycock April 8, 2009

  2. History • Named after Dr. Rudolf Diesel • Originally replaced the stationary steam engine • 75% efficient compared to10% by steam engine • 1894 filed for a paten for his new invention • By 1898 Diesel was a millionaire • Used to power anything from electrical and water plants to marine craft • About 50 % of new cars in Europe are Diesel (2007) Diesel Engines, By: Douglas Aycock

  3. How the Diesel Engine Works • Four Stroke • Intake - air enters • Compression – compresses and heats air • Combustion – fuel combusts, and pushes piston down • Exhaust – pushes exhaust out Diesel Engines, By: Douglas Aycock

  4. Diesel Engines Compression Ignition Higher compression ratio 14:1 - 25:1 Can burn petroleum diesel, synthetic, and biodiesel Fuel ignites when mixed with air Gas Engines Spark plug ignited Lower compression ratio Up to 14:1 (high performance) Can burn gasoline Fuel and air mixed then ignites Differences Diesel Engines, By: Douglas Aycock

  5. Advantages Over Gas Engines • More torque and less RPM’s (revolutions per minute) • Better fuel economy – 20% - 30% over gas • Easier maintenance - no tune-ups • Tougher engine components • Last longer – average 350,000 miles (gas – 250,000) • Higher energy density fuel • one gallon Diesel fuel = 147,000 BTU • One gallon Gasoline = 125,000 BTU Diesel Engines, By: Douglas Aycock
