The steam is clear when the engine and/or the atmosphere is warmer. Moved to golf cart community and for last year averaged 175. Worn cylinder and/or rings As the engine is running at 3600 RPM’s that piston is moving extremely fast. Air in the fuel can also cause white smoke. Steam is usually caused by a lack of sea water flow through the water-injected exhaust system. WHITE SMOKE White smoke often occurs when there is either too much fuel being injected into the combustion chamber, or not enough heat to burn the fuel. pressure. Also, check for water leaks that may have found their way into the fuel tank or engine block. Very little smoke is expected due to the condensation of water from the exhaust gases. This can overfill the crankcase with oil by x2, x3, x4 or more in capacity! Generator could be running without issue and then the clear exhaust smoke begins to turn white and then stays white means that there is some water within your fuel system. White smoke is usually caused by the engine running too cold, a faulty injector or injection timing, or engine coolant leaking into the dry section of the exhaust manifold. It might be a small problem, it may be the beginning of a huge issue, but either way, a quick reaction will ensure that the … They range from faulty fuel injectors to retarded fuel injection timing, or even low compression. This can occur if coolant is leaking into the head. White smoke on a cold start, and then it disappears as the engine warms up This is very common. This is usually a result of faulty head gaskets or cracked cylinder heads or blocks. The reason that a faulty piston ring or a scored/gauged cylinder wall will cause white exhaust is similar to reason #1 in the first section. However, there might be a more serious situation, when water enters the system. White smoke is a sign of water vapor or fuel that has been atomized but not burned. From there, it works its way around the piston, passed the 3 rings (since the rings simply cannot prevent that much volume from seeping by), and the oil then flows on top of the piston where it is compressed with the fuel/air mix from the carburetor and is part of the combustion process. The increased internal pressure pushes the liquid oil up the combustion cylinder to the bottom of the piston. Vapour is natural result of fuel combustion. While the exhaust system is still cold the vapour is partially condensed so it becomes visible, and on a cut of an exhaust pipe usually there is … White Smoke Indicates a Faulty Fuel System: Time for a Fuel Injector Service . link to How Long Can I Leave the Car Radio on? This is not smoke, it’s steam! White smoke occurs as a result of combustion temperature being so low that only partial combustion occurs and the partially burned fuel that exits the exhaust is in the form of a white vapory smoke. The key of longevity for any engine is regular maintenance. Top 7 Reasons White Smoke is Coming From Your Tailpipe. In order to function properly, a diesel engine needs precise timing of the injector pump and high. Step 1: Inspect The Intake Gasket. Low cylinder compression is another, albeit not so common cause of white plumes. Check hoses. If left alone and if the engine continued to run, it would produce white smoke until it had burned off enough oil until the oil level in the crankcase returned to tolerable levels for acceptable internal pressures. I guess it depends on the engine, but I would consider this one to be an easier fix than the previous section — at least on the engines that I’ve had the pleasure of working on. Depending on the make and model, you’re essentially going to have to remove the recoil starter cord, then the starter cup and fan wheel. link to Here's How Long Can You Leave Your Car's Headlights On, Terms and Conditions for Home Battery Bank. And if you drive a petrol car and see white smoke, it’s really not good news. This is a problem which can have many causes. You can replace these things, but it is not worth it when you consider the price of replacement parts vs. the cost of a new unit. Anyway, when there is excess oil added to the crankcase, the inside of the crankcase builds up added pressure as the engine gets very hot during operation. White Smoke Indicates a Faulty Fuel System: Time for a Fuel Injector Service, The key of longevity for any engine is regular maintenance. It could also be as simple as water entering the exhaust or carburetor after the engine was pressure-washed. Please consult a certified electrician if there is anything you are uncomfortable with. By far, the most common reason your generator will be sending out a cumulus cloud of white exhaust will be because there is too much oil in the crankcase. It happens every day. It will often happen at startup in cold weather with lower compression engines. Car in garage when not in use. Any time you see a change in the behavior, you need to address it. This is nothing but steam caused due to condensation. These parts take the role of distribution the combustion mixture, along with the coolant to the separated intake port. On the other hand, if the smoke is a bluish white, … I’m going to explain simply why each of these things occurs and how you can go about fixing it to get your generator running correctly again and not creating a smokescreen that the military would be proud of! If you can think of any other reason why an engine might blow white smoke let me know and I’d love to update this list. The only help here is cylinder honing. I now drive 70% highway and 30% city. I hope you found this article helpful! Faulty or damaged injectors; Incorrect injection timing (could be a worn timing gear or damaged crankshaft keyway). The good news about that is that if I can fix it, you can too! It could have far-reaching consequences further down the line. Broken or leaking valves are among top causes of low compression, but far from only culprits. To be more specific, the white smoke you see is your diesel fuel, unburned, or only partially burned. Inoperative crankcase breather. This is especially a problem if you bought your generator used from someone who wasn’t very mechanically inclined. If this article helped you out, I’d love to hear that as well! We've all accidentally left our car's headlights on at one point or another during our driving careers. Where the combustion occurs, as the piston squeezes and compresses the fuel and air, is known as the combustion chamber. It might be a small problem, it may be the beginning of a huge issue, but either way, a quick reaction will ensure that the engine life is not compromised and that the costs to you are not unnecessarily high. The commonest reasons for this lie in the fuel system. So, any decrease in the pressure or delay in the fuel delivery to the combustion chamber will result in incomplete combustion, leading to white smoke. The crankcase is simply the cavity where the oil sits and the rotating parts of the engine cycle around in a circle and are lubricated by the oil. If it does, it is time for a fuel injector service. If the rings don’t make a proper seal between the piston and the cylinder wall, or if the cylinder wall itself has damage to it that prevents a seal between itself and the rings, then oil will be splashed up from the crankcase below and will glide up the cylinder wall with the piston but will work its way to the top and combust with the air and gasoline in the combustion chamber. white smoke coming out if exhaust when i first start it in the morning. Inhaling carbon monoxide could lead to unconsciousness and death in less than three minutes if 12,800pm (1.28) is being inhaled. After that the flywheel and then you’ll have to remove the bolts and break the seal on the crankcase cover to get into the sump of the crankcase. White smoke from any vehicle exhaust, specially when the engine or weather is cold is nearly always steam which is a normal product of burning petrol. Diesel Generator white smoke when running indicates water in the fuel. It might be a small problem, it may be the beginning of a huge issue, but either way, a quick reaction will ensure that the engine life is not compromised and that the costs to you are not unnecessarily high. As it compresses and combusts it will blow some of that compression and exhaust through the damaged gasket and into the pushrod cavity where it will make its way to the crankcase. Yet another option is cylinder glazing, which is basically a patina of sorts coating the cylinder. White smoke from the exhaust pipe on startup, idle or acceleration is telling us that there is coolant or water that is getting vaporized. I've been an avid hobbyist in these fields for over 5 years and I enjoy sharing what I've learned in a way that's geared for beginners and those just getting their foot in the door with small engine repair and prepping. White smoke coming from the lawnmower should never be ignored as it can potentially be a sign of a serious problem with your mower’s engine that needs immediate attention. This usually makes an engine a lot louder than normally. Some causes of this include. White smoke from your diesel generator occurs because of un-burnt fuel in the exhaust gas or water in the fuel.
