I am interested in finding the specs for diesel injector nozzles, especially the DN type. I am using a DN0SD193 for an Isuzu pup truck but am experimenting with different nozzles to improve performance using veg. oil. I am guessing from what I have been able to gather that the DN is the type, the 0 is degree spray pattern, S is the size. I'm not sure about these and am at a loss as to what the 193 and other numbers such as that at the end mean. If anyone knows about specs to decipher the "code", it would help me make some choices without just trial and error (that gets expensive!). Also, if anyone had experience with nozzles for veg. oil, that would be helpful as well. I am thinking that a wider spray pattern might help, etc.
Thanks for any help.
