The main causes of black smoke emission include the following. Each one of these systems can vary in the design specs even for the same engine; this is depending on the application and configuration of the genset. If the exhaust system of diesel generator set needs to add exhaust muffler, the muffler should be reasonably selected and installed to minimize the back pressure of exhaust system caused by muffler installation. For this discussion, the exhaust back pressure is the gage pressure in the exhaust system at the outlet of the exhaust turbine in turbocharged engines or the pressure at the outlet of the exhaust manifold in naturally aspirated engines. Larger waste can also damage the blades of the turbocharger. Therefore, each diesel engine should use a separate exhaust system. For a well burned diesel generator set, the smoke from the exhaust pipe is colorless or light gray. After replacing the air filter element, press the button switch on the end of the maintenance indicator to reset it. How Can We Maintain Oil Filter of Diesel Generator Set. It must minimize back pressure, which can cause horsepower losses and temperature increases that can shorten the engine’s life. When designing a smoke extraction system, the most basic consideration is that the back pressure should not exceed the allowable range, because excessive back pressure will greatly reduce the efficiency of the engine, durability, and severely increase fuel consumption. 1. Larger waste can also damage the blades of the turbocharger. . Leakage of exhaust gas usually detects leakage sound or can be seen that high temperature gas discolors the material near the leak. var cnzz_protocol = (("https:" == document.location.protocol) ? " There s air in the fuel line of the oil engine, which affects the fuel supply and fuel injection. The external exhaust pipe should be firmly fixed to the hull without vibration and its weight should not be applied to the expansion tube of the diesel engine. 36 $207.58 $207.58 Expansion joints are not allowed to eliminate misalignment between tubes. The inner diameter of the external inlet pipe should be larger than the expansion joint, and too much bending should be avoided. ENGINE-GENERATOR SYSTEM 263000 MARCH 2016 PAGE 1 OF 8 DESIGN GUIDELINE 263000 ENGINE-GENERATOR SYSTEM AND ROOM Scope: This guideline defines the requirements and standards for design of engine-generators and associated system components. The return pipe is connected to the bottom of the middle shell of the supercharger, and the oil goes back to the diesel fuel pan along the return pipe. Check for cracks or perforations in the hose, soft movement of the clamp, tighten or replace if found, to ensure that the intake system does not leak. The cylinder is not tightly closed, and the engine oil burns in the combustion chamber. . Generator exhaust extension systems from GenExhaust.com enable you to extend the exhaust of your generator outside, allowing you to keep your generator protected inside from inclement weather. As a consequence, emission levels of these exhaust gas components became regulated. The return pipe is connected to the bottom of the middle shell of the supercharger, and the oil goes back to the diesel fuel pan along the return pipe. The main cause of white smoke emission include the following. The temperature of diesel engine is too low. Oil leakage from the seal ring is rare, but it can still occur. D. There s air in the fuel line of the oil engine, which affects the fuel supply and fuel injection. Whether you have a generator that requires a single generator clamp, generator flanges, generator gaskets, generator stainless flexible tubing, generator exhaust silencer or an entire Generator exhaust system we are here to help. Please install heat insulation measures on the surface of the external exhaust pipe. The oil is too much and the water is less, making the burning is incomplete. The valve clearance is too large, or the timing gear is not installed correctly, resulting in insufficient intake and exhaust impurity or late fuel injection. Air entering the unit cylinder should be kept clean (if the air enters the cylinder with dust and dirt, it will cause early wear and tear of the cylinder sleeve, piston ring, and also damage the valve rod and duct. The main cause of white smoke emission include the following. . Noise. Ruspet Exhausts For guaranteed excellence in industrial exhaust manufacturing and installation Ruspet Exhausts are … ules dry exhaust pipe is used in the exhaust system of diesel generator set, which can make full use of exhaust energy and give full play to engine performance. I n addition, the genset is equipped with a diameter of 127mm exhaust elbow and exhaust bellows, easy to connect. Adds: No.2 Xingguang Road, Guxi Industrial Park, Taixing, Jiangsu, China. If the smoke from the exhaust pipe is black, white and blue, the unit is not properly exhausted. (2) Diesel generator oil supplies the supercharger with bearings and provides some cooling with its working oil pressure through the tubing. Air leakage in the intake system, in addition to inspection with the naked eye, but also with soap foam in the possible leak to check. A suitable silencer compatible with the exhaust pipe is used to reduce noise and it can be installed indoors or outdoors. Temperature sensor in the car exhaust system, located behind the diesel particulate filter in a car on a lift in a car workshop, seen from below. The installation of the exhaust pipe must comply with relevant regulations, standards and other requirements; ensure that the hot exhaust muffler and exhaust pipe are easy to move away from Burning substances; ensuring that the emitted smoke does not become a public hazard. A 90° pipe bend increases the length of the system and back pressure. The oil in the oil basin is too much oily, and too much oil is formed and splashed into the cylinder wall and burned into the combustion on chamber. (3) Air leakage in the intake system, in addition to inspection with the naked eye, but also with soap foam in the possible leak to check. So how to diagnose and analyze the intake and exhaust system of diesel generator. 3. The water is heated and turns into white steam. Air entering the unit cylinder should be kept clean (if the air enters the cylinder with dust and dirt, it will cause early wear and tear of the cylinder sleeve, piston ring, and also damage the valve rod and duct. Pipes and silencers, whether indoors or outdoors, should be kept away from flammable substances. Since regulated emission levels are often much lower than that which can be achieved through in-cylinder control meas… If the smoke from the exhaust pipe is black, white and blue, the unit is not properly exhausted. Therefore, each diesel engine should use a separate exhaust system. The breakdown of supercharger reduces its supercharging efficiency and causes the decrease of diesel engine power and the increase of smoke. E. Cylinder compression force is seriously inadequate. The installation of the exhaust pipe must comply with relevant regulations, standards and other requirements; ensure that the hot exhaust muffler and exhaust pipe are easy to move away from Burning substances; ensuring that the emitted smoke does not become a public hazard. (2) Too much smoke or lower power of turbocharged diesel engine may be due to loosening of pressure section of intake pipe or serious leakage of rubber pipe. Engine Exhaust Considerations The exhaust system of a generator has several inherent design problems that must be considered. Diesel generator oil supplies the supercharger with bearings and provides some cooling with its working oil pressure through the tubing. do not allow the operation of diesel generator sets without air filters. When several diesel generators are installed together, some problems may arise if a general external exhaust pipe is used. The valve clearance is too large, or the timing gear is not installed correctly, resulting in insufficient intake and exhaust impurity or late fuel injection. When several diesel generating units are working at different times, condensate water produced by diesel engine exhaust will enter the non-working diesel engine and will easily damage the diesel engine parts. Any long horizontal or vertical exhaust pipe should be installed diagonally downwards and fitted with a drain valve that should be at the lowest point to prevent water from flowing into the engine and silencer. Note: after installation of exhaust system, diesel engine back pressure must not be greater than 6KPA, otherwise diesel engine performance will be affected. Copyright © Jiangsu Starlight Electricity Equipments Co., Ltd.All Rights Reserved | Sitemap . A. High intake and exhaust resistance creates a vacuum between the compressor and the supercharger housing, causing the sealing ring to leak oil. Otherwise, it is easy to cause early wear and tear of diesel generator set. C. There is water in the fuel oil or there is a water leak in the cylinder. Intake air leakage of diesel generator set. Too much air intake resistance causes black smoke and power reduction (air filter can be blown three times with compressed air and will have to be replaced later). Designs exceeding 3m must be approved by the manufacturer. These characteristics impose severe limitations on what can be done to silence the engine exhaust noise: nVery High Noise (100 to 120 dBA @ 1 m) nHigh Temperatures (950 to 1050 ο F) nHigh Velocities (5,000 to 15,000 fpm) Expansion joints are not allowed to eliminate misalignment between tubes. FLACHAU, AUSTRIA - MAY 10, 2017 : The AdBlue tank at the BP gas station on highway rest stop in Flachau, Austria. The external exhaust pipe is made of steel pipe, and the turbocharger of the diesel engine must be flexible connected. Motor vehicle exhaust gases. air filter resistance should be checked when the diesel engine is calibrated. If the return tube of the supercharger is blocked or damaged, the oil pressure in the middle shell will rise and the oil will flow along the seal to the compressor or turbine inlet vortex shell. o how to diagnose and analyze the intake and exhaust system of diesel generator. The air inlet should be located away from all kinds of heat sources, and the exhaust gas from the exhaust pipe should not be inhaled into the intake pipe. Seal rings are arranged at both ends of the rotor part of the supercharger. The temperature of generator exhaust systems gas leaving the engine is generally in the region of 500°C. C. Low cylinder pressure, low compression temperature, poor combustion. Injector nozzle spray poor atomization or dripping oil. The inner diameter of the external inlet pipe should be larger than the expansion joint, and too much bending should be avoided. Generator Exhaust Section. These temperatures, combined with the frequent start/stop exercise cycle of generators, already create a serious challenge to the exterior paint used on carbon steel silencers. The installation method of diesel generator intake and exhaust system is as follow: In order to provide enough fresh air for diesel generator set operation, diesel engine intake should be arranged in the air circulation place outside the engine room. https://" : " http://");document.write(unescape("%3Cspan id='cnzz_stat_icon_1261919589'%3E%3C/span%3E%3Cscript src='" + cnzz_protocol + "s4.cnzz.com/z_stat.php%3Fid%3D1261919589%26show%3Dpic' type='text/javascript'%3E%3C/script%3E")); What are the precautions for the diesel generator set exhaust system?
