Smokey diesel

Post Reply New Topic

In work I often have to drive forklift trucks along with everyone else for that matter. The counter balance is great, the telescopic one is also great but the side loader billows an unending cloud of black, acrid smoke and fills up a 30000 square foot workshop in minutes with pungent fog.

The foreman has messed around with it to try and cure it of it's ailments but instead of curing the smoke problem, somehow made it twice as fast for some reason. This obviously makes it twice as fun to drive around the yard but makes it responsible for most of the towns nitrogen oxides pollution. Leaving it on outside for a minute or two gets rid of some of the smoke but even then, driving it into the workshop gives the same death stares as putting a baby in a microwave. Revving it in any way, shape or form within the workshop is even worse.

It also seems to be puffing a lot of smoke from a hose within the engine compartment, so much smoke that it's formed a strange tar like layer on the bed. Even after it's switched off it still seems to huff and puff residual smoke from the engine compartment so we decided to remove the entire cover for said compartment.

Any ideas of what the problem might be?

The smoke is black, I presume?
It sounds like it's not completely burning the fuel during the power stroke.

Does it keep cycling after it's been powered off (does it huff and puff like it's still on)?

Fuel cleaner and possibly new injectors.

Babies do not normally fit in microwaves.

I think it's more of a rich fuel problem than a dieseling problem. The oil levels never seem to drop but there is a noticeable puff every time the accelerator is pressed. I'm thinking perhaps air intakes. As for the amount of fuel it's using it's hard to tell as like all heavy as hell industrial vehicles it drinks fuel like an airliner.

Do you mean filter? If so then you jogged my memory and it's probably stinking. I thought the injectors usually give much worse signs of problems like constant stalling or is that just my inept guess and mechanics (I'm not the best at it)


Are you sure?

I'd be curious what the A/F ratio is because it does seem likely that it's running rich, at least that would explain the if there's soot and the residue left from that hose in the engine bay.

That said, I don't think there's enough information about the problem or enough expertise on the board to get a diagnosis. I think your boss needs to get a diesel mechanic to look at it.

Fuel itself can get dirt in it where an additive as a fuel cleaner helps.
I only know the basics.
A Citreon Xantia I used to have for a short while would go fast but leave a black cloud behind. I was told it was the injectors. Injector cleaner is another fuel additive.
