<p>[quote user="Overmod"]I don’t know why any engineer would quote “10%” as an example for DEF mixing. I have never heard of more than 3% as an extreme hypothetical case, with most engine architectures only requiring 1 to 2%. [/quote]</p> <p>I found your 1 to 2% in a Cummins broschure for truck motors and 5% in another one. I didn't find the consuption for a railroad engine.</p> <p>The intention was to show that there are measures to work with the different consumtion rates of fuel and DEF. I said " If DEF consumtion is 10% of diesel fuel make the DEF tank 15% of the fuel tank size." Perhaps I better would have sait "if it were".</p> <p>I didn't pretend that 10% is the DEF consumption I just took an arbitrary number to make point. At least that was the intention. I know what I want to say but sometimes the result is a bit different in a foreign language<br />Regards, Volker.</p> <p>Edit: I found numbers for a Caterpillar C175-16 Tier 4 generator set:<br />- Fuel consumption at 100% load: 174 gal/hr<br />- DEF consumption at 100% load: 12 gal/hr<br />Source: <a>s7d2.scene7.com/is/content/Caterpillar/C10332678</a></p> <p>The numbers are on page 4. The DEF consumption is 6.9% of fuel consumption</p>
