Smoker With Turned Up Pump Video
 

Was looking at some smoker videos on YouTube..and happened to come across this 1572 with a turned up pump... http://www.youtube.com/watch?NR=1&fe...&v=LMzBiNQ2YZA


I don't believe it is a good idea to do so..but was just curious what others thought about it, just for the heck of it.. :biggrin2:

Sounds like a bad record but it's throwing out some smoke.:bigthink:

Black smoke from a diesel like that is just unburned fuel and he's actually making less power.

I don't think the the black smoke means less power. On our pulling tractor it has more power with black smoke than when it's lean and smoking gray. I have been wanting to do the same thing to the 782D but don't know where the screw is. As far as affecting reliability it should have no effect whatsoever. I know i'm comparing apples to oranges but our IH 1566 has over 300 hp and it is our main farm tractor. It has ran like that (with over 300 hp) for 20 years (since we put it together) and is completely stock minus injectors and injection pump. Even though they are not similar in size a diesel engine is a diesel engine no mater how you look at it and they are all built similar so reliability should not be an issue.

Rolling black smoke reminds me of hauling coal in the old freight shakers we had turned up back in PA.

Also Sam may have done this, but if you wanted to roll black smoke in the cat 777, hold the brake on and push the fuel to the floor. It would load up fast!

Iv always been told black smoke is wasted fuel, but it was cheap back then.

Follow the fuel line..and there should be a screw right where the line goes into the injection pump.

It's your engine so if you want to make smoke have at it. I've only been around diesels for about 50 years. Cat's, Cummins, Detroit's, Mack’s, Volvo's and Kubota's. Every manufacturer has told me the same thing, black smoke is less power and a shorter life. The 980C in this pic had 20,000 hours on it before overhaul and the main and rod bearing wear still in spec for re use. Yep I don’t know what I’m talking about, you go make smoke son. :biggrin2:

I do agree that turning up the pump all the way wouldn't help HP, because all your doing is giving more fuel, and no more air (to much of a difference in ratio).

However, I do believe 1 turn or so would add power, because you are adding so litttle fuel, that the engine could probably make up the small difference in air to fuel ratio through the intake. Just my :TwoCents:

I have always been told that if you turn the fuel up, or run a tuner that yo need to watch your exhaust temps so that you don't do any damage. Now maybe on these little diesels there is little chance of that. I know in my 882 that if I am just riding around the yard pulling the cart or sweeper I just go at a high idle, tons of power.

Sorry if I offended you, I'm just going by what works for us on farm and pulling tractors. I don't want to make my 782D smoke like that. I just want to turn it up a .5 to 1 round to give it a little more punch.
