Volkswagen TDI
A Modern Diesel…
2
Why A Diesel?
  • The TDI is capable of over 50 miles per gallon.


  • This means a 700+ mile cruising range… or fewer stops for fuel during the week (my personal best is 802-miles on a single tank).


  • More torque (delivered at low RPM) than comparable gas powered cars enables the TDI to deliver similar performance and low RPM cruising at highway speeds.
3
Why A Diesel?
  • Better mileage means less time and money spent at the fuel pump.


  • Higher torque at lower RPM means less shifting at fluctuating speeds.


  • Less maintenance means fewer headaches.  There is no distributor, spark plugs, tune-ups, or valve adjustments.  Just replace the oil, filters, and belts as scheduled.

Myths About Diesels...
5
Myths About Diesels...
  • “Diesels are noisy…”
6
Myths About Diesels...
  • Not anymore.  Direct injection technology reduces engine noise.
7
Myths About Diesels...
  • Computer-designed sound-deadening engine covers help reduce noise even further.
8
Myths About Diesels...
  • This cover was designed by measuring sound levels at every square inch.
9
Myths About Diesels...
  • “Diesels are slow…”
10
Myths About Diesels...
  • Not anymore.  With 177-ft/lbs on tap, the TDI performs on par with most similarly displaced gasoline powered engines, even some V6’s.
11
Myths About Diesels...
  • Performance chips or modules boost the TDI’s performance by up to 30%.
12
Myths About Diesels...
  • And all suspension, intake, and exhaust modifications popular with gassers will work on the TDI.
13
Myths About Diesels...
  • Even Volkswagen Motorsport has adopted the use of diesel-powered racecars.
14
Myths About Diesels...
  • This 4-cylinder TDI produces 207-bhp and over 320-ft/lbs of torque.  But its forte is that it races twice as long between fuel stops.
15
Myths About Diesels...
  • “Diesels are smelly…”
16
Myths About Diesels...
  • Not anymore.  There is a soot smell when the car first starts.  Once the computer takes over the exhaust smell is only DIFFERENT, not worse, than a gasser’s.
17
Myths About Diesels...
  • “Diesels smoke a lot and pollute our air…”
18
Myths About Diesels...
  • Not anymore.  Diesel technology is expanding by leaps and bounds.  The US is far behind the rest of the world.  As the fuel in the US improves, so will the diesel technology that’s available to us.
19
About TDI Emissions...
20
About TDI Emissions...
  • The TDI is NOT a Powerstroke, Cummins, or Duramax diesel engine.  Nor is it an Over the Road 18-wheeler.
21
About TDI Emissions...
  • The TDI meets all emissions standards for passenger cars.
22
Compared to Gasoline Powered Cars...
  • TDIs emit 30% less Carbon Dioxide (CO2), a Global Warming Gas.


  • TDIs emit almost NO Carbon Monoxide (CO), a well-known poison.


  • TDIs emit much lower Hydrocarbons.
23
Compared to Gasoline Powered Cars...
  • Oxides of Nitrogen (NOx) emissions are higher on a TDI when compared to a new gas vehicle.  However, a gas vehicle’s NOx output slowly increases over time.


  • Tests revealed that both cars emit the same NOx levels by 50,000-miles.  After that, the gasoline powered car emits more NOx.


  • It is estimated that NOx emissions between the two cars would be similar over the life of the cars.
24
Compared to Gasoline Powered Cars...
  • Particulates are where “special interest groups” scare the public with diesels.  Yes, it’s true diesels emit more PM10 soot particles (particles up to 10-microns).


  • However, gasoline-powered cars emit more PM1 particles, which are more likely to be breathed deeply into the lungs instead of being sneezed out like dust.  Although PM10 “looks” dangerous (‘cuz it’s ugly), PM1 likely does the body more harm.
25
And Then There’s Biodiesel...
  • This could take a separate presentation by itself.


  • But here are the basics:
26
Biodiesel – The Basics...
  • Biodiesel is a cleaner burning alternative fuel made from renewable domestic resources such as soybeans, canola, and other plants.
27
Biodiesel – The Basics...
  • Unlike other alternative fuels, biodiesel can be used in any diesel engine without modification.
28
Choosing Biodiesel Over Diesel...
  • True Cost:  In 1996, it was estimated that the military costs of securing foreign oil was $57 billion annually.  Foreign tax credits accounted for another estimated $4 billion annually and environmental costs were estimated at $45 per barrel.  For every billion dollars spent on foreign oil, America lost 10,000 – 25,000 jobs.


  • The use of biodiesel drastically reduces our dependence on foreign oil, keeps our farmers actively employed, and boosts the economy.

Biodiesel Is Less Toxic Than Table Salt and More Biodegradable Than Sugar...
