International Truck and Engine recently handed out “A
Guide to Scientific Research on Diesel and Natural Gas Engines”
at a “Green Diesel Technology” meeting. In it,
they claim that “Recent scientific research confirms
that advanced, low-emitting engine technology and ultra-low-sulfur
fuel make diesel trucks and buses as clean or cleaner than
natural gas….” Can it be true? Well…not
with an honest “apples to apples” comparison.
Many of the studies cited were funded by International and
none make honest comparisons. For example, they compare
new diesel buses with advanced particulate traps (and ultra-low
sulfur fuel) against old natural gas buses with no pollution
controls. In a fair comparison, the buses would have the
same level of technology. And while International speculates
about diesel and NG safety, statistics show there has never
been a natural gas fuel system related fatality in the US!
Why is International adamantly against NG? Perhaps because
they have no heavy-duty natural gas engine to sell. Click

“Fact Sheet,” comparing their claims with the
“real facts.”
