Diesel Engine Smoke: Blue, Black, or White?

Feb 07,  · White Smoke White smoke can be caused by either excess fuel or an internal coolant leak in your engine. This is a case where you’ll probably want to call in the diesel pros, but here’s a diagnostic tip: While the engine is smoking, hold your hand over the exhaust outlet for 20 seconds or so. Don’t restrict the exhaust, just attempt to.

Diesel smoke like blowby and oil use is a worrying engine symptom which indicates that an engine is not what regions did sir francis drake explore 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 developingthat 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 what does white smoke from a diesel mean 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 what does white smoke from a diesel mean 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, what causes long term constipation 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. It indicates poor and incomplete combustion of the diesel fuel. There are many causes, including. 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. 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, what is stand up paddle surfing 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 what is inquiry- based science 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.

The oil can enter the combustion chamber for several reasons. 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 what is corporate environmental responsibility 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 what does white smoke from a diesel mean 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. Some causes of this include. 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. It is evident as pressure coming out the crankcase ventilation tube, valve cover what does white smoke from a diesel mean or dipstick tube.

Engine oil leaks can also result from excessive cylinder blowby, as the excess pressure finds the weakest point. Some causes include. Cost Effective Maintenance has demonstrated that excessive blowby in these units can be minimized at low cost and without downtime. 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.

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?

What does it mean if my engine is blowing blue smoke? Worn valve guides or seals Wear in power assemblies i. Some causes of this include Faulty or damaged injectors Incorrect injection timing could be a worn timing gear or damaged crankshaft keyway.

Oct 10,  · White Smoke from Diesel Exhaust. White smoke in diesel engines is usually the last color you want to see, particularly on gas cars. If the smoke is thin, and goes away relatively quickly, than it is merely condensation. However, thicker, longer lasting smoke is a much larger headache. Your engine is more than likely burning coolant. Diesel engines can emit blue, black or white smoke from their exhaust while running, and each color can indicate a fault with a part or system. White smoke points to some very specific conditions which can indicate a number of component or system failures.

A marine diesel that shows a bit of smoke on start-up is probably nothing to worry about, but if it keeps on smoking after a few seconds of run-time, or starts smoking after it warms up, or when you throttle up, that engine is screaming to you to get something fixed.
