Diesel engine designs striving to increase engine performance have made great progress in engine fuel delivery to the combustion chamber. diesel engine is now quieter, smoother and more powerful. But today's diesel engine owners overlook an important factor. The quality of diesel fuel today has not kept pace with the engine upgrades.
Diesel fuel begins to deteriorate as soon as it occurred. Within 30 days of refining, all diesel fuel regardless of brand, goes through a natural process called re-polymerization and oxidation. This process forms varnishes and soluble gums in the fuel, making the fuel molecules to stretch and bond together. These components now fall to the bottom of the fuel tank and form asphaltene also known as diesel sludge. The fuel begins to be dark in color, smell bad, and in most cases causes the smoke from the engine. The rest goes to the exhaust as unburned fuel and smoke. With the increase in cluster size they begin to reduce the clogging of the filters of fuel flow. It is estimated that eight out of ten diesel engine failures are directly related to poor quality and contaminated fuel. The accumulation of contaminants in the fuel systems and storage tanks can quickly clog filters, thus leading to the outside of the motor, the wear of the fuel pump and damaging the diesel engine.
This threat requires that we realize the burden on diesel fuel instead of gasoline. Gasoline is only as fuel. diesel, moreover, must also cool and lubricate the injection system. Water moves diesel fuel. wear when the fuel is moved occurs because lubrication is now missing.
The water that enters the results of the combustion chamber in other damage. Water causes corrosion of tanks, lines, injectors, and greatly reduces combustibility.
Bacteria also present a serious problem. Bacteria feed of nitrogen, sulfur and iron that may be present in the fuel or the tank.
There is absolutely no algae in diesel fuel. You can have fungus and microbial contamination but no algae. Why is there so much bad fuel?
The number one reason is because of the growing popularity of diesel power and the accompanying increased demand for more diesel fuel. There was a time when diesel fuel remained in the refinery storage tanks long enough to naturally separate and settle, allowing the clean fuel to delete. Now, with the increased demand, diesel fuel never remains stationary long enough to solve, and water and suspended solids are sent to you, the user.
The change in refinery techniques is another problem. For more products per dollar; diesel fuel is now being refined from more marginal portions of the crude barrel. Thirdly, current fuel distribution methods also have a negative impact on the fuel condition at the time of delivery. In many cases, brokers control fuel sales to major distribution terminals and determine delivery dates. The solution packages hardware and multifunctional diesel additives.
Many formulations of diesel fuel additives address key issues regarding the fuel performance; some to improve fuel economy, increase lubrication, improving cold flow, and improve cetane number. Most diesel fuel additives contain combustion improvers that release oxygen during the compression stroke. This allows combustion to start sooner, providing a more complete fuel burn. A more complete burn all the fuel supply blocks and the motor is capable of producing. As improved combustion and you get a smooth running engine, a power increase which improves fuel economy and reducing black smoke emissions.
Cetane is a performance evaluation of a diesel fuel, a higher cetane number or cetane rating indicates greater energy efficiency. cetane influences of fuel, time white smoke after starting, driveability before warming up, and intensity of diesel knock at idle. Increasing the cetane number of a fuel and you have a better performance.
In diesel fuel, fuel lubricates the fuel pump and injectors. Fuel A with low lubricity may cause excessive wear and premature failure of these components. Improve lubrication and extend engine life.
Diesel fuels have pour points (lowest temperature at which an oil or another liquid shed) under conditions outlined in the range of normal winter temperatures. As fuel approaches its pour point of the fuel in the form of paraffin wax crystals that keep coming. flow improver additives modify the wax crystals, lowering the levy and fuel point give better cold weather performance.
Storage tanks for other issues to be considered. So adding new, fresh fuel always has a bit of the bad added all the time fuel is purchased. The fuel will always be bad fuel until the core problem is addressed
The order of treatment for fuel related problems should always begin with a determination of the existence of water in the fuel and if the fuel has microbes (fuel bugs) in it. water issues and fuel test kits can be used for this maintenance phase. Biocides kill bacteria, that's all!
The issue of water should be repaired first by the use of fuel water separators on the tank or equipment. The following is a multifunctional chemical additive should be added to improve the fuel efficiency, and then, if necessary, a specific additive to dissolve the sludge or diesel and a corrosion inhibitor to protect steel tanks. For long-term prevention, it is recommended the use of the magnet fuel conditioners. These devices continually reverse the fuel re-polymerization during circulation and reduce the need for continued use of additives.
