Re: What does the future of diesel engines in farm machinery look like?

Diesel engines have a use in agriculture but they need to follow the same 
constraints that other diesel-engine-users follow. For years farmers and 
agribusiness have held the opinion they are better and more important than 
others when it comes to environmental impacts. There is no good 
justification for this position. 
The biggest current problem with diesel engines is the emission of small 
particles from their exhaust. These particles, less than 10 microns in size 
and called PM10, can lodge deep in the lungs where they are hard to clear 
from air passages.
