DIESEL Engine Exhaust SMOKE ..

The information below is primarily aimed at diesel engines, since they commonly have the most smoke problems, but it will also help with petrol engines and 2-stroke petrol/oil fueled engines.

THE COLOUR of diesel engine exhaust smoke and when it occurs can tell you a lot about the internal condition of a diesel engine.

 

SMOKE COLOUR ..

Basically there are 3 types of smoke emitted from a diesel engine .. black, blue and white.

Basically, smoke from a diesel engine indicates that something is not right.  Smoke 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.

Smoke 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, 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, smoke may be your last chance to act before a catastrophic engine failure occurs (eg piston seizure, valve or turbocharger failure).

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, but that would only apply to older technology diesel engines.  In modern type diesels .. no smoke at all should be evident.


 

BLACK smoke ..

Black smoke is the most common emitted from diesel engines and indicates incomplete combustion of the fuel. Black smoke causes can vary widely and include ..

  • Incorrect fuel injection timing .. commonly too retarded.
  • Fuel injection pump wear, or incorrect settings .. commonly retarded.
  • Faulty cold start, or faulty advance/retard mechanisms .. commonly retarded.
  • Incorrect air/fuel ratio setting .. excessive fuel to air ratio.
  • Under-performing turbocharger .. pressure low, or air leaks.
  • Air leaks in inter-cooler pipes .. pressure loss.
  • Dirty or worn fuel injectors .. commonly carbon deposits affecting spray pattern.
  • Carbon deposits in combustion chambers .. common in lightly loaded engines.
  • Excessive carbon build-up around exhaust valves and exhaust spaces.
  • Sticking piston rings .. often due to carbon deposits.
  • Glazed cylinder cross-hatch .. due to carbon deposits.
  • Incorrect valve clearances .. often timing error when replacing cam-belts.
  • Faulty valve stem seals .. rarely.
  • Engine wear in general .. often misdiagnosed when carbon deposits are the real problem.
  • Engine oil viscosity too low .. check oil grade against operating conditions.
  • Cool operating temperatures .. coolant should reach 85C, or higher. Check thermostats.
  • Exhaust gas recirculation (EGR) system faulty, or blocked with carbon.
  • Engine overloaded .. reduce load, use lower gear, clean the anti-foul, change propellor pitch.
  • High altitude operation .. lack of oxygen to complete fuel burn.
  • Dirty or restricted air cleaner systems .. air intake filter partially blocked.
  • Poor quality fuel.

Black smoke can occur across the entire operating range, but is usually worst under full power, or during the lag before the turbocharger boosts air supply to match the fuel usage such as in the early stages of acceleration and during gear changes. Moderate turbo lag smoke may be acceptable, otherwise black smoke should be hardly visible in a correctly running engine.  

Obviously, worn or damaged components must be replaced .. the earlier you identify and fix the problem, the less damage will be done.  Keep on top of engine tune issues, including valve adjustments, regular servicing of air, fuel and oil filters.  Do not buy fuel from suspect outlets.  Dirty engine components, such as fuel 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, FTC is what you need.

Cleaning the internals of engines is usually considered only possible at physical overhaul, however, we 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 (DeSLUDGE Flushing Oil Concentrate).

Black smoke is high in carbon or soot, which is an undesirable product of diesel combustion.  The combustion of diesel is a complicated process of breaking down the various hydrocarbon fuel molecules into progressively smaller and smaller molecules, by extremely rapid burning (explosion) in the presence of oxygen.  The main and ideal end products of combustion are CO2 (carbon dioxide a greenhouse gas) and water.  It is believed that the last step in the process is carbon monoxide (a 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.

BLUE smoke ..

To go directly to products that reduce engine BLUE smoke click here

Blue smoke is caused by engine lubricating oil burning. The oil can enter the combustion chamber from several sources including ..

  • Worn valve guides, or seals
  • Cylinder &/or piston ring wear
  • Cylinder glaze
  • Piston ring sticking
  • Incorrect grade of oil .. too thin and getting past rings, or valves guides
  • Fuel dilution of the oil, making it too thin.

Blue smoke is often evident at cold start, which can reflect reduced oil control due to carbon fouling deposits around the piston rings and/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 stage.

An engine may actually burn oil without the evidence of blue smoke, because good compression burns oil quite cleanly, however, it is not acceptable for any new engine, or engine in good internal condition to burn large amounts of lubricating oil .. with or without blue smoke.

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 SupaSLIP achieves this for many of our customers

WHITE sometimes more GREYISH smoke ..

To go directly to products that reduce engine WHITE smoke click here

White smoke is caused by raw, unburnt fuel passing into the exhaust stream. Common causes include ..

  • Incorrect fuel injection timing
  • Defective fuel injectors
  • Low cylinder compression

Low cylinder compression may be caused by leaking valves, sticking piston rings, ring wear, cylinder 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.

Continuous evidence of white smoke indicates a mechanical defect, or incorrect fuel timing.

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 .. unfortunately, expensive mechanical repair is the only proper solution here.

EXHAUST SOOT ..

EXHAUST SOOT continued ..

You may wish to read further about the wear that soot can cause when in engine oil as a result of "blowby", which is what makes diesel oil look BLACK.

HINT about decarbonising an engine ..

Sometimes an engine can throw out a lot of exhaust soot during the 1st few hours of using FTC catalyst engine decarboniser .. don’t be surprised if you see that happening. But, you may need to clean the surfaces near the exhaust exit more than usual .. especially transoms with exhaust ports on boats.

FTC catalyst engine decarboniser slowly burns carbon deposits in all combustion and exhaust system areas. Hard carbon takes longer to remove than soft deposits. The harder the motor is worked the quicker the removal.

 

PS .. A decarbonised engine will reduce air pollution .. often greatly!!


ENGINE FOULING DEPOSITS (usually CARBON related) ..

FTC_pistons.JPG

Engine Fouling deposits can be safely removed as you drive by adding FTC catalytic engine decarboniser to the fuel .. and using the companion product DeSLUDGE FOC at the next engine oil change. You may also consider using SupaSLIP in engine oil to improve performance and reduce frictional wear.

DIESEL engine EXHAUST SMELL

 

Diesel engine exhaust SMELL can tell you something about the engine condition.

If the idling engine exhaust smells like raw (unburnt) diesel and stings your eyes, then it is likely that either the fuel injector tip ports (fine fuel spray holes) are partially blocked, or the fuel injection timing is very retarded. Partially blocked injector tips are quite common in “direct” fuel injection engines. If the smell and sting occur only at cold start, the glow-plugs may be faulty, or they may need more heating time before the engine is started.

Note: exhaust gases are highly poisonous .. avoid breathing them, especially in enclosed areas.
