In the previous article, we talked about the main causes of wear and corrosion of cylinder liners. In this article, we will continue to talk about how to reduce abnormal wear and corrosion.
Abnormal wear and corrosion of cylinder liners will affect the normal service life and performance of the engine. So how can we reduce the occurrence of these situations? The following five points are very important:
First, strengthen the cleaning and maintenance of the filter to keep the air filter, oil filter and fuel filter in good working condition at all times. Strengthening the maintenance of the three filters can effectively reduce the impurities and mechanical impurities in the air entering the cylinder, thereby reducing the wear of the cylinder liner and extending the service life of the engine. Especially on the air filter, check whether the filter element and the sealing rubber gasket are damaged. For the oil bath air filter, check whether the oil level in the oil pan meets the regulations.
If the working conditions of the vehicle are relatively bad, you can replace the relevant filters in advance to keep the vehicle in a good condition. In addition, although the inferior three filters on the roadside are cheap, for the sake of long-term use of the vehicle, try not to touch these things.
Secondly, use compliant engine oil and fuel, strictly select lubricants with the best viscosity value according to the season and engine performance requirements, and regularly check and maintain the quantity and quality of lubricants. You should know that some inferior lubricants will become thinner when the temperature rises, and will rise to the piston ring to cause carbon deposits and snap rings. Some inferior engine oils will become thicker due to poor thermal oxidation stability, which will greatly reduce the lubrication effect. In addition, inferior engine oil has poor cleaning ability and cannot take away all impurities, which will cause impurities such as particles and metal chips to wear inside the engine.
You also need to pay attention to the selection of coolant, check the quantity and quality of coolant regularly, and maintain a normal replacement frequency. Above we mentioned the hazards of using inferior coolant, which is one of the important factors causing cavitation and wear of engine cylinder liners.
Maintain the normal operating temperature of the engine and avoid too low or too high temperature. According to data, the normal operating temperature of the engine should be between 80 and 90 degrees Celsius. If the temperature is too low, the engine cannot maintain good lubrication, which will increase the wear of the cylinder liner. At the same time, the water vapor in the cylinder is easy to condense into water droplets, dissolve the acidic gas molecules in the exhaust gas, generate acidic substances, and corrode and wear the cylinder wall. If the temperature is too high, the cylinder strength will be reduced, the viscosity of the lubricating oil will decrease, and then the wear of the cylinder liner will be aggravated.
Especially at high altitudes on the plateau, the vehicle is in a high-pressure and heavy-load state for a long time and the waterway is in a large circulation state, which is obviously not conducive to the service life of the engine. Looking back, there may be certain problems with the configuration of the whole vehicle for the current operating route. Using the vehicle under such a high-intensity overload is more likely to cause failures.
Reasonable and correct maintenance of the truck can effectively extend the service life of the vehicle. The main methods to reduce abnormal wear and cavitation of the engine cylinder liner are to meet the vehicle configuration, maintain and replace the three filters, select genuine engine oil and coolant, the appropriate operating temperature of the engine, and maintain the normal mechanical performance of the engine. Truckers should never buy inferior products just for the sake of cheapness, otherwise it is easy to lose more than you gain. If you want to buy truck spare parts, you might as well choose us!
