smoke for diesel engines

Well by "unrealistic smoke" I meant the models sitting or moving along with a really large plume of gray smoke coming out of them like they were on fire. On a steam engine, OK, but way overdone on the MTH diesels that I've seen. <br /> <br />As I also mentioned, these large scale engines have large tanks to hold the smoke fluid. Using a suitably sized smoke unit that will fit into an HO scale diesel would not leave much room if any to install a reservoir. And then there's the access to the smoke unit to add fluid pretty regularly. Make a removable roof hatch? <br /> <br />I had a smoke chimney in a sawdust burner on my modular layout, and would insert some fluid into it using an eyedropper. It would only hold a few drops, smoking for 5-10 minutes or so. I would only load it up once in a while as I did not want it to smoke all the time. It ran on a fixed voltage from a power pack accessory terminal. <br /> <br />I wonder if such a unit would work with the lower voltages of an operating engine? I burned out the smoke units twice in my sawdust burner, don't know if I let them run dry with the power still on or not . When the third one (at $20.00 each) failed, I forgot about it. So another thing to consider - can you keep smoke fluid in the unit, or would you be able to turn it off? If its connected to the engine's power, then it would be on all the time and would probably be toast if let run dry. <br /> <br />Some things to think about. <br /> <br />Bob Boudreau
