Help with diesel emission information

[Dieselnut59]

Hello all. I am looking to sell new forklifts to a customer of ours. They currently have pre-emission propane lifts in their warehouse. They have 30 forklifts ranging from 2000# to 6000# capacity. I want to sell them new "clean diesel" equipment to not only offer cleaner emissions but to eliminate the explosion hazards and refueling hassles associated with propane. Any information any of yall can help provide will be greatly appreciated. The lifts are manufactured by Doosan (formerly Daewoo) and have the 2. 3 liter and 3. 3 liter Cummins engines. They are Tier II emission compliant and I plan to order them with the optional catalytic exhaust to make them even cleaner. I currently have a demo model with the catalytic exhaust at their location. It is amazingly clean running and has NO smoke or smell. They LOVE it. I just need some emission characteristics data for the new "clean diesel" technology, but have been unable to find it anywhere, including on Cummins and Doosan's websites. How do the new diesel engines compare to propane in "real numbers"?

Thanks for any help!

John

"The same emission limits apply to all vehicles regardless of the fuel they use. That is, vehicles fueled by gasoline, diesel, or alternative fuels all must meet the same standards. Since light-duty emission standards are expressed in grams of pollutants per mile, vehicles with large engines (such light trucks or SUVs) have to use more advanced emission control technologies than vehicles with smaller engines in order to meet the standards. "



Diesel Progress Magazine had a very good article on Diesel EPA standards. Full dyno test reportedly with no soot in tailpipe.



I was curious why the new Tier II diesel engines EXHAUST smells funny. Like a M1 turbine tank engine. :-{} Apparently getting it hot enough to burn the soot has a unique smell.



But, oh well, propane engines EXHAUST has an odor to me too.



The site above gets to most of your questions.

Thanks for the information! I found some other research that stated similar things. Tier II emissions regulate all forklifts for emissions across the board, regardless of fuel. The fuel going into the engine is obviously what makes the engine cleaner. Propane has not been changed in formulation since its introduction as a motor/heating fuel. Gasoline has gone through many changes and diesel has received the most drastic changes to clean it up, notably the significant reductions in sulfur. Even with computer controls and 3-way catalysts, the tier II gasoline/propane lifts are still not as clean as the new mechanical pump (no computer) tier II diesel units running ULSD. I went a step beyond and am adding catalytic exhaust and using ULSD B20 to fuel them. These machines are the cleanest running engine powered forklifts around and they (the customer) are THRILLED with them!
