<1>. Oil filter: The oil will contain some foreign particles during use. These particles have friction-generated particles, parts do not clean the remaining impurities, and there are also parts of the early oxidation metamorphic particles produced by high temperatures. There are iron pins, sand grains, rubber particles, etc., mixed in the engine oil will cause frictional side effects, damage and even burn tiles, reduce service life and reliability. The oil filter must be used on the diesel engine. The oil filter is mainly used for paper filtration. The filter paper filters the impurities in the oil. Some filters can be divided into primary and fine filters, which can filter out 0.040mm particles by 100%, and filter particles from 0.030-0.040mm by 99%. Particles below 0.030mm can cause deterioration if the concentration is too high. Can filter more than 0.010mm particles 100%, 95% more than 0.005mm filter out, if the use of poor quality oil filter, in use in case of blockage or resistance increases so that the main oil pressure drop caused The amount of oil in the main bearing is not enough, causing serious consequences. Â
　　 <2>. Diesel filter: The diesel filter mainly filters out the dust and impurities that enter the fuel pump. Because these dust and impurities will damage the fuel pump and the injector and other components, the user must select the high quality standard diesel filter. Cleaner.
 <3>. Water grid : Coolant should be filtered because of mud, sand, dust, oil and scale, iron corrosion deposit after processing, protective agent that precipitated, and deterioration of sealing gasket debris. In the engine, especially after a certain period of storage, (supplementary water also contains dust, silt, etc.) will hinder the thermostat work, contaminate and plug the water pipe in the oil cooler, block the radiator (water tank), soft Cooling water channels in pipes, pipes, and cylinders. Silt and other scales of metal shavings may cause abrasion of the impeller and the shaft of the pump, causing damage to the cylinder liner seal, the seal of the pump's face and the wear of the thermostat, these particles and metal chips, seal fragments, etc., if stuffed into the thermostat, The thermostat can no longer be opened and closed, so a standard water filter must be used and replaced regularly.
 <4>. Air filter : The common light single-stage dry air filter is used on the Cummins diesel engine (generator set). The high-quality standard filter element is made of specially processed filter paper, and can be replaced with high efficiency. 99.5%. Fresh air enters the air filter from around the air filter. The air required for diesel combustion also depends on the air filter. Therefore, the smaller the air filter resistance, the better. The air filter is used. After a certain period of time, the filter element will become dirty and the resistance will increase. If the resistance increases beyond the specified value, the diesel engine will not be able to obtain enough air for combustion, and thus will produce smoke, lack of power, etc. The air resistance indicator installed on the air intake can indicate whether the air resistance is normal. If the resistance exceeds the specified value, the indicator changes from normal green to abnormal red. At this time, the filter should be replaced and then the indicator. Click on the end to restore it to green.
 <5>. Engine oil : The use of high-quality engine oil, and the use of appropriate oil replacement and oil filter replacement cycles are an important factor in extending the service life of the diesel engine. Cummins and Rolls-Royce do not recommend any specific grade of engine oil.
The role of oil:
1) The oil used in high-speed diesel engines such as .cummins & perkins must be multi-functional and have the following main functions:
Lubrication: Provide oil film lubrication between moving parts to reduce friction and wear.
Cooling: As a thermal medium, it removes heat from the critical surface and acts as a cooling element.
Sealing: filling the cylinder wall, the uneven surface of the valve stem and sealing in the oil seal of the turbocharger.
Cleaning: Suspend dirt in it so as not to form scale on the surface of engine parts, and to clean it.
Damping and cushioning: especially high pressure components such as gears and push rods.
Prevents oxidation and corrosion: protects parts. Â
2). When the engine oil in the diesel engine loses the above function, it must be replaced. The engine oil is rarely lost under normal conditions, but it is easily polluted, thus losing the function of protecting the diesel engine. Oil contamination is a normal result after the diesel engine is running. Because During the operation of the diesel engine, many contaminants enter the engine oil. They are: By-products from the combustion of diesel engines: Bitumen produced from incomplete combustion of fuel oil, soot, and acids. Acids, coke, and scale: Due to cracking of engine oils or decomposition Dirt produced by oxidation: Contaminants that enter the diesel engine through intake air, fuel oil, and engine oil or oil. Â
3). Engine oil performance specifications: The ap (american, petroleum, institute American Petroleum Institute) classification of cf-4 and sae15w-40 are American Petroleum Institute's current level for high-speed diesel engines. Â
　　 <6>. Coolant : Cooling water for diesel engines should be clean. There are no corrosive compounds such as chlorides, sulfates, and acids. The water should be slightly alkaline. The ph value should be between 8.5-10.5, and it must be Add dca anti-rust water.
