Diesel Engine Repair Experience 1. Causes of Unstable Engine Speed If a diesel engine is running at high speed but the fuel line is not blocked, you should check the low-pressure tubing. An unstable speed can occur when the speed control rod is bent. A bent governor may cause irregular movement during speed adjustments, creating resistance and leading to fluctuating engine speed. 2. How to Use Lera’s Technique Effectively For diesel engines that have been in use for a long time, the clearance between the connecting rod and crankshaft tends to increase, and the crankshaft journal may wear down over time. This can result in frequent oil leaks. To prevent this, simply replace the bearings and scrape a small bevel on both ends of the bearing to improve oil retention, which helps reduce the risk of oil leakage and improves overall performance. 3. What Does "Oil Beads" in the Water Tank Mean? If you notice a drop in engine power and see oil beads or bubbles in the cooling tank, it's time to shut down the engine and perform maintenance. One of the first things to check is whether the cylinder liner has developed cracks. Cracks can allow compressed gases to push oil from the cylinder wall into the cooling system, resulting in visible oil droplets and air bubbles in the tank. 4. Additional Tips for Diesel Engine Maintenance Regular inspection of fuel injectors is also essential. Clogged or worn injectors can lead to poor combustion, reduced efficiency, and increased emissions. Additionally, keeping the air filter clean ensures proper airflow, which is crucial for optimal engine performance. It's also recommended to monitor the coolant level and quality regularly to prevent overheating and internal damage. By following these simple steps, you can significantly extend the life of your diesel engine and avoid costly repairs in the future. QC Purchasing Service For Ingredients
