No one bush-burning diesel Edit seasonal use of lubricants. Different seasons should use different grades of oil. Some diesel bush-burning, because summer is the use of small viscosity oil in the bush can not form a film due to the contact surface. Second, the lubricating oil dirty. If dirty oil added to the body, it will cause clogging of the oil bush-burning. Third, pay attention to observe the instrument. When the diesel engine oil pressure should be normal (0.15 to 0.25) between MPa, idling engine oil pressure not less than 0.5MPa. Many machine hand rarely pay attention to see the oil pressure gauge, and therefore can not be found hidden faults. The fourth is to add the right amount of oil is not. If too much oil marine engines offer, easy to burn the oil when the engine is running, the formation of carbon, if it is too small marine engines, is due to poor lubrication bush-burning axle. Usually the oil surface in the most appropriate scale up and down between the dipstick. Fifth, long-term overload caused by bush-burning. Work overload due to chronic marine engines manufacturers, engine temperature, low speed, carrying capacity bearing increases, a corresponding reduction in the fuel supply pump, combined with lower oil viscosity at high temperatures, more likely to cause bush-burning. Sixth, with the gap between the shaft and tile does not meet the standards. The gap is too small, the oil is not easy to enter, can not form a film layer, the gap is too large, easy to drain the oil, the oil film layer is difficult to form. Therefore, when the repair assembly must be guaranteed within the standard range of bearing clearance. Development of marine diesel engines in models look relatively stable overall, marine engine dealer a few years ago, focused on improving the reliability of the model, this is because the development of the supercharger technology, diesel strengthening of improved quickly, especially oil crisis After reflected in reduced fuel consumption and low-quality fuel oil burning to pursue the goal of a strong economy, national environmental policy limits on diesel emissions increasingly harsh, and increases NOx, SO2 and other harmful emissions is the high strength a byproduct of burning low-grade fuel oil, and the content of these types of harmful exhaust gas components, marine diesel engine diesel worse than cars. Each diesel engine manufacturers are committed to following the common pursuit of the new diesel engine.
