Black Diesel Ute blowing black smoke out of the exhaust

Diesel Smoke tells YOU a Story…

Diesel Smoke tells YOU a Story

Diesel smoke (like blowby and oil use) is a worrying engine symptom which indicates that an engine is not running well, and its service life is likely to be shortened considerably, unless remedial action is taken.

Basically, smoke from a diesel engine indicates that something is not right. It should be taken as an indication that there is a problem existing (or developing), that will potentially shorten the engine life, or result in unnecessary costs. It should be regarded as an opportunity to take measures that will save you money in both the long term and also the short term. At the least, that smoke may be due to a simple problem, that is causing poor combustion efficiency, and costing you in excessive fuel bills (eg carboned up engine from excessive idling, stop start operation or short run times). At the other end of the scale, it may be your last chance to act, before a catastrophic engine failure occurs (eg piston seizure, valve or turbocharger failure).

Stop Diesel Smoke Product Pack

This pack will stop your diesel blowing smoke or your money back!

Simply add to your fuel and oil and the problem is solved.

Should my engine be blowing white, blue or black smoke?

A diesel engine in good condition should produce no visible smoke from the exhaust, under most operating conditions. A short puff of smoke when an engine is accelerated under load may be acceptable, due to the lag before the turbocharger speed and air flow is able to match the volume of diesel injected into the cylinders. That would only apply to older technology diesel engines, but with modern type diesels, no smoke at all should be evident.

There are three basic types of smoke, as identifiable by their colour. And then there is blowby smoke (or just blowby).

Black Smoke from Diesel Engines

BLACK SMOKE is the most common smoke emitted from diesel engines. It indicates poor and incomplete combustion of the diesel fuel. There are many causes, including

  • Incorrect timing
  • Dirty or worn injectors
  • Injectors sticking open too long (Common Rail Diesel type)
  • Over-fuelling
  • Faulty turbocharger (ie not enough air to match the fuel)
  • Incorrect valve clearance
  • Incorrect air/fuel ratio
  • Low cylinder compression (eg sticking piston rings or worn components)
  • Dirty air cleaner
  • Restricted induction system (eg system too small or kinked inlet piping)
  • Carboned up intake manifolds (esp Common Rail Diesels)
  • Other engine tune factors
  • Poor quality fuel
  • Excessive carbon build up in combustion and exhaust spaces
  • Cool operating temperatures

  • Carboned up intake manifolds (esp Common Rail Diesels)
  • Other engine tune factors
  • Poor quality fuel
  • Excessive carbon build up in combustion and exhaust spaces
  • Cool operating temperatures

Obviously, worn or damaged components must be replaced, and the earlier you identify and fix the problem, the less damage will be done. Keep on top of engine tune issues, including valve adjustments, and regular servicing of air, fuel and oil filters. Do not buy fuel from suspect outlets. Dirty components, such as injectors can be easily restored to full cleanliness by using an effective and reliable fuel system cleaner. If you choose from our range of products, Cleanpower is what you need.

Common rail diesels are the new hi-tech breed of diesel to meet ever increasing emission standards. Operating pressures and temperatures are several times higher than older technology, and tolerances are much finer, making them more susceptible to fuel and deposit issues. Injectors and pumps are naturally more expensive, but problems can, and do, melt pistons and destroy engines. CRD Fuel Enhancer is fast becoming the standard for correcting and prevention in Australia.

Cleaning of internals of engines has usually only been possible at overhaul, however, Cost Effective Maintenance provide two products to enable vehicle and equipment owners to quickly, safely and cheaply restore full cleanliness to combustion and exhaust spaces (FTC Decarbonizer) as well as piston rings, oil pumps, oil galleries, oil coolers, piston skirts, valve gear, etc (Flushing Oil Concentrate).

Black smoke is high in carbon or soot, which is an undesirable product of diesel combustion. Now, the combustion of diesel is a complicated process of breaking down the various hydrocarbon fuel molecules into progressively smaller and smaller molecules, by burning in the presence of oxygen. The main and ideal end products of combustion are CO2 and H2O (carbon dioxide, the greenhouse gas and water). It is believed that the last step in the process is carbon monoxide (the poisonous gas) to carbon dioxide. This is also the slowest step by far, and when combustion conditions deteriorate some upstream bottle necking occurs in the chain of combustion reactions. This results (according to some authorities) in polymerization of smaller partly burnt molecules into much larger ones, which become visible as soot, or black smoke.

What does it mean if my engine is blowing blue smoke?

BLUE SMOKE is an indication of oil being burnt. The oil can enter the combustion chamber for several reasons.

  • Worn valve guides or seals
  • Wear in power assemblies (i.e. cylinders, piston rings, ring grooves)
  • Cylinder glaze
  • Piston ring sticking
  • Faulty turbocharger seals
  • Incorrect grade of oil (eg oil too thin, and migrating past the rings)
  • Fuel dilution in the oil (oil thinned out with diesel)

  • Cylinder glaze
  • Piston ring sticking
  • Faulty turbocharger seals
  • Incorrect grade of oil (eg oil too thin, and migrating past the rings)
  • Fuel dilution in the oil (oil thinned out with diesel)

At cold start, blue smoke is often evident, and can reflect reduced oil control, due to fouling deposits around piston rings or cylinder glaze (which is actually carbon deposited in the machined cylinder crosshatching. These tiny grooves actually hold a film of oil, which in turn completes the seal between the combustion chamber and the oil wetted crankcase). Blue smoke should not be evident at any time, but it is worth noting, that engines with good sound compression can actually burn quite a lot of oil without evidence of blue smoke. Good compression allows oil to burn cleanly, as part of the fuel. It is not good though!

Once again, restore physical cleanliness to all components. Replace worn parts where necessary. In some situations, where the engines are pretty worn, but you just need to keep them in service, cleaning with the previously mentioned products, followed by effective additional anti-wear protection, will reduce internal stresses on all those tired components, providing extended service life. Our AW10 Antiwear achieves this for many of our customers.

Diesel Engines Blowing White Smoke from Exhaust

WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned. Some causes of this include

  • Faulty or damaged injectors
  • Incorrect injection timing (could be a worn timing gear or damaged crankshaft keyway).
  • Low cylinder compression (eg caused by leaking or broken valves, piston ring sticking, cylinder and/or ring wear, or cylinder glaze)

When white smoke occurs at cold start, and then disappears as the engine warms up, the most common causes are fouling deposits around piston rings and/or cylinder glazing. Use of our Flushing Oil Concentrate and FTC Decarbonizer address these respective problems.

Water entering combustion spaces will also create white smoke. Faulty head gaskets and cracked cylinder heads or blocks are a common cause of water entry, and are often to blame. Unfortunately, expensive mechanical repair is the only proper solution here.

What is Blowby Smoke?

BLOWBY (or BLOWBY SMOKE) is the emission of crankcase pressure (and fumes/smoke) out the crankcase ventilation system, and generally regarded as a clear indication of an urgently needed, and expensive, engine rebuild.

It is evident as pressure coming out the crankcase ventilation tube, valve cover breather or dipstick tube. Engine oil leaks can also result from excessive cylinder blowby, as the excess pressure finds the weakest point. Some causes include

  • Sticking piston rings
  • Worn cylinders
  • Worn or broken piston rings
  • Cracked pistons

In practice, only about 20% or less of diesel engines have suffering excessive blowby caused by worn or damaged parts.
Over 80% are attributable to piston ring deposits that cause the rings to bind in their grooves. Cost Effective Maintenance has demonstrated that excessive blowby in these units can be minimized at low cost and without downtime.

Bought Decarbonizer and the Flushing Oil Concentrate to use on my tractor and excavator, sadly a... bit too late for the digger....needs a rebuild. But the tractor was a definite improvement, the engine ran sweeter and a lot less gunk from the exhaust, really noticeable. Thoroughly recommend, the only suggestion is to maybe reconsider the product names....bit confusing. But names are not everything, absolutely worth the money. Many thanksread more

Frankly, I am astounded with the difference. I have been using the FTC Decarbonizer for the last... 1,500k. My mechanic has warned me the engine on my Winnebago Motorhome (Chevy 6.5L turbo diesel, 17 yrs old, 225k on the clock) was exhibiting signs of blow-by. There is now no evidence of smoke from the exhaust under load, the performance has improved, the engine just runs smoother, but incredibly it starts first time after being a difficult starter for several years. I am looking forward to its next service to see what the mechanic has to say. Great product.read more

I have used the AW10 in several cars now. It has made a HUGE difference in all of them. My little... junk Barina that I drive to the train station had a noisy engine and it got hot fast. After using the AW10, it is quiet and the temp takes a while to get to it's working temp. The car runs really well now. All the other cars are running well too.The Rust Conqueror is AMAZING. Works so much better than anything else I have tried. I first saw the XTroll rust treatment way back in the late 80's. It was fantastic back then. Over time I lost the can and moved states. I needed to treat some rust and nothing I used worked properly. I searched for the XTroll and found it with the Cost Effective Maintenance team. They were so helpful. The stuff isn't cheap but it is more than worth it. You want your equipment to last, Use the AW10 and XTroll. Look at the other products too. You won't regret it.read more
