Black blue and white smoke from diesel engine

Your diesel engine is equipped with a governor that helps control the amount of fuel that gets delivered to your engine’s cylinders depending on the load your engine is experiencing. The occasional puff of black smoke that may occur when you suddenly push your throttle to the max is really nothing more than the governor shooting some extra fuel into the injectors before the engine catches up and comes up to rpm. Consistent smoke coming from the exhaust most likely indicates a deeper internal problem with the engine. A small puff of smoke during quick acceleration is acceptable with older diesel engines due to a lag before the turbocharger’s air flow can match the increased volume of diesel fuel injected into the cylinders. Basically, smoke from a diesel engine indicates that something is not right.

Diesel Smoke tells YOU a Story. 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. This means that part of the diesel fuel remains unburnt and turns into black soot. It indicates poor and incomplete combustion of the diesel fuel.

If you notice a truck consuming more motor oil than normal without blue smoke , there are probably worn parts that need to be replaced. White smoke can mean unburned fuel in your exhaust. If you see white smoke when you cold-start the engine and the smoke disappears as the engine warms, the common cause is fouling deposits on the piston rings.

Perkins has a wealth of knowledge about diesel engines amassed through years of research, development and testing of its own models. Blowing white smoke is a red flag for your diesel engine , yet we see this happen all the time to our customers. In many cases, white smoke emanating from the tailpipe (often at idle once the engine reached operating temperature) typically means a worn out injector.

The most common causes are worn piston rings or valve stem seals. Another cause coul be that your crankcase ventilation valve is malfunctioning. Older diesel engines will always make a little black smoke , especially under load.

A vehicles exhaust color means alot. White exhaust smoke indicates coolant is burning in the combustion chamber, blue exhaust smoke indicates oil, and black exhaust smoke indicates a rich condition. Exhaust smoke is a way of your car communicating with you to say what is wrong. Usually, the smoke that get emitted is black , white , grey and blue. The exhaust gases is an old school way to detect symptoms of problems i. EGR is blocked and its over fueling.

Or as many people call it, “rolling coal”. People throw tuners, modules, or some kind of smoke switch, onto their diesel to make the truck add more fuel than necessary to create black smoke, as well as install larger injectors. The black smoke disappears, engine power restores and fuel consumption oil waste reduce.

Engine smokes: Blue or dove-colored smoke. The mainreason for the appearanceof blue smoke - oil gets into the engine cylinders. Oily smoke may have blue color with various hues - from transparent blue to blue - white , depending on the engine operating condition, and the degree of the oil heating that got into the cylinders.

Black Smoke is the most common emitted from diesel engines and indicates incomplete combustion of the fuel. Each engine has valves that open and close. These Valves are manufactured to open mechanically by pressure from a Rocker Arm. They let air and gasoline come into the engine.

Blair Lampe is a New York-based professional mechanic, blogger, theater technician, and speechwriter. Most diesel cars (if not all) emit a small amount of black exhaust smoke while accelerating. It takes some time for the engine system to develop enough revolutions (RPM) and power to burn the fuel.

If, however, a preheat device such as glow plugs or an air-intake heater are malfunctioning, the production of white smoke may be excessive and longer lasting.
