The term turbo is no stranger to most of us, and most cars on the market are now relying on turbo engines. Turbocharged cars have certain advantages in terms of power and fuel economy, but these advantages require the owner to develop some good driving habits, otherwise turbocharger will cause damage to the car. Here are some of the things that owners need to be aware of when talking about turbocharged cars?
The first is the need to use good quality oil. The analysis of the reasons for the burning of motor oil on the market today is mostly due to the damage of the seal between the turbocharger and the intake pipe. The main reason for the seal damage of the seal is that the cycle of replacing the oil is too long or a poor quality oil is used. As a result, the floating turbine main shaft lacks lubrication and heat dissipation, resulting in damage to the seal and causing oil leakage. The choice of a good oil can increase its oxidation resistance, abrasion resistance, lubrication and heat dissipation.
Followed by the use of turbocharged cars usually pay special attention to the timely replacement of oil filters and air filters, but also to maintain the cleanliness of the turbine. Because the air contains a lot of impurities, once the dust particles enter the high speed operation, the dust particles will make the dust particles hit the supercharger, which will cause the turbine to run unstable and cause wear. Therefore, vehicle owners need to periodically check whether the turbocharger is damaged, and the easiest way to identify is to hear whether the engine has abnormal noise or unusual vibration, and whether the sealing ring is sealed.
Finally, the cold car starts slowly, the hot car idles and then turns off. Because when the cold car starts, the oil temperature is not only relatively low but also relatively viscous, resulting in poor oil lubrication. During this process, if the owner forces the turbine to work at full capacity, it will accelerate its wear and tear. Another point that requires the owner to pay attention to is that the engine is turned off immediately after parking, which will cause the cooling system and the supply of lubricating oil to stop and cause damage to the vehicle bearing. Therefore, let the car engine run for 2-3 minutes before the flameout to ensure that the turbine has enough time to cool.
To see Xiao Bian talking about so much, nothing more than to remind owners to use the car must develop good driving habits, the only way to play out the advantages of the turbine, while also extending the life of the car.
Construction Hydraulic Filters
Filter working principle diagram of hydraulic oil from the left into the pipe to filter, from the filter flow to the inner core, again from export flow, when the filter clogging, pressure, to achieve the relief valve opening pressure, the oil through the overflow valve, the inner core, again from exports, outside filter than inside the filter of high precision, the element belongs to the coarse filtration.
Two, hydraulic filter test method: at present, the world has widely adopted the international standard ISO4572 "hydraulic filter core filtration performance of multiple pass method", the test content includes to determine the filter core, the filter ratio of different sizes (β value) plugging process pressure difference characteristics and scale capacity. The multi-pass method simulates the actual working condition of the filter in the hydraulic system. The pollutants constantly invade the system oil and are filtered out by the filter, while the particles that fail to be filtered return to the tank and pass through the filter again. In order to meet the needs of high precision filter performance evaluation, and because of the change of test dust and the use of new automatic particle counter calibration method, ISO4572 has been modified and improved in recent years, after modification, the new standard number ISO16889 has been adopted by the test method for many times.
