White smelly smoke from diesel engine

What could make a diesel engine produce white smoke? What causes excessive white smoke from a diesel engine? Why does my diesel engine have white smoke? Why is my engine plowing white smoke?

But mostly, it is the incorrect injector timing in the cylinders. To be more specific, the white smoke you see is your diesel fuel , unburne or only partially burned. The commonest reasons for this lie in the fuel system. They range from faulty fuel injectors to retarded fuel injectio n timing, or even low compression.

If you smell a strong diesel odor , the white smoke means the extra fuel is in such excess that it can’t even begin to ignite (as compared to black smoke , where partial ignition has occurred). Typically, this white smoke indicates a serious fuel injection problem. The most noticeable symptom of internal coolant leakage is when the white smoke is billowing out of the exhaust pipe and leaves a sweet odor in the air. An engine burning coolant can be easily determined. First question, do you have to regularly add coolant?

This typically occurs due to the engine being too cool to burn the fuel , often resulting from low compression in one cylinder, problems with the fuel injection timing or a defective fuel injector. Condensation that accumulates inside the exhaust pipes, converter and mufflers can produce a puff of white smoke upon diesel engine start-up. In very cold temperatures, the heated exhaust can freeze into minute fuel droplets when exiting the exhaust and produce a more prolonged emission of white smoke for a very short period of driving time. In many cases, white smoke emanating from the tailpipe (often at idle once the engine reached operating temperature) typically means a worn out injector.

Now this isn’t always the case, but after some trouble shooting we’re usually the go-to shop when diesel drivers need refurbishe rebuilt, or new injectors. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned. Diesel Engines Blowing White Smoke from Exhaust.

Some causes of this include. Analyzing the color and smell of diesel exhaust emissions can tell you the performance and component conditions of the engine. 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. This is usually the last color of smoke 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. Low engine cylinder compression.

The unburnt fuel particles blow out the tailpipe producing a rich, thick, diesel fuel odor. It is normal to see white smoke from the exhaust during sub-zero and colder weather, at least until the engine warms up. The good news is, white smoke alone is not an indicator of this problem. White smoke generally happens when there is not enough heat to burn the fuel. Along with the white smoke , you will be able to smell a sweet odor.

Sometimes, you can also see that the coolant reservoir level is low. WHY DIESELS SMOKE : Diesel car engines get smoky because of a few common reasons. Identifying the smoky colours, often black or white smoke , can help you diagnose the cause of the problem.

That in turn can help you cure and stop a smoking diesel engine. Do you see white smoke from a diesel engine when accelerating or startup? If smoke is being release then this is indicative of a problem. HOWTO looks at all the possible reasons why white smoke is coming from your exhaust pipe. I ran diesel purge through the system and replaced the fuel filter.

Blue Smoke Occurs When Starting A Diesel Car: Damaged Glow Plug Damaged glow plugs cause blue smoke from car. When starting up a diesel engine , we need to use a glow plug to cause ignition of diesel fuel. Once the engine is warmed up, the use of the glow plug is not necessary as the heat of the engine makes ignition of diesel fuel.
