Diesel engine repair and maintenance encompass a range of essential tasks that ensure the optimal performance, longevity, and reliability of diesel engines. Understanding the specific requirements and best practices associated with diesel engine care is crucial for maximizing efficiency and minimizing costly breakdowns. In this article, we will delve into the key specifications of diesel engine repair and maintenance.
Robert Sikorsky, a famous American engineer, listed five main causes of engine wear in his book forever driving.
After the fuel is burned in the engine combustion chamber, a large number of harmful substances will be produced. Generally speaking, every 100 gallons of gasoline produces 1-5 pounds of nitrogen and sulfuric acid. These substances will not only cause corrosion to the cylinder, but also rush into the engine through the three piston rings (upper ring, middle ring and lower ring), causing metal corrosion to the main components of the engine, such as cam and crankshaft. This corrosion cannot be eliminated only by the use of lubricating oil.
After the engine is shut down, it will cool from high temperature to low temperature. This temperature change process will produce water-cooled condensate, and even ponding in the engine. This will cause serious metal corrosion to the engine, especially when the engine is restarted in a short distance and the engine temperature is too late to evaporate water vapor. This kind of wear cannot be solved by lubricating oil.
The engine needs to inhale air during combustion, and even the best air filtration device is difficult to prevent dust from being sucked into the engine with the air. Strong wear is caused by inhaled dust, which cannot be completely eliminated by lubricating oil. Especially in China’s dry, rainless and windy areas, this strong wear is more prominent.
GM’s research shows that when the engine stops running for 4 hours, all the lubricating oil on the friction interface will return to the lubricating oil tank. At this time, start the engine. Since the oil pump does not have enough time to send the lubricating oil pump to all lubricating parts, the dry friction of periodic loss of lubrication will occur in a short time, resulting in serious abnormal and strong wear of the engine. This strong wear cannot be solved by lubricating oil. (according to other relevant data, this strong wear accounts for more than 70% of the total wear of the engine).
Once the engine leaks oil, water and gas, it will cause increased fuel consumption, accelerated wear and tear of parts, and decreased power. To solve the problem of “three leaks” in Diesel Engine Repair And Maintenance, let’s take a look at the causes of “three leaks” first.
Proper Diesel Engine Repair And Maintenance can effectively extend the life of your diesel engine, reduce the failure rate, and lower costs. In order to improve your work efficiency and reduce costs, please carefully understand the correct use and Diesel Engine Repair And Maintenance methods. Specialized accessories and oil should be used.
Oil changes are often overlooked, but to be honest, they are very valuable. Fresh oil helps to lubricate the moving parts of the engine, absorb heat and reduce carbon deposition. To learn more about which oil is suitable for your truck’s diesel engine and the oil change frequency of your truck, please check your owner’s manual. You can also check the dipstick every few weeks. If you don’t have enough oil, top it up.
