When operating excavators, one of the most common issues faced is abnormal increase in diesel consumption or burning oil. This not only raises equipment operating costs but also leads to equipment wear and failure. To address this issue, it is crucial to identify the root causes of increased fuel consumption or burning oil.Excessive Wear of Components: The wear of the piston, piston ring, and cylinder liner can cause oil to escape into the combustion chamber, leading to a sharp increase in oil consumption.

When it comes to Japanese imported machines, the Komatsu excavator stands out for its exceptional performance and durability, winning the hearts of machine enthusiasts in the Chinese market. However, regardless of the series, after thousands of hours of operation in various construction environments, Komatsu excavators encounter the challenge of adjusting the hydraulic pump.

The primary differences between Komatsu original (OEM) filters and aftermarket filters lie in their quality, performance, and cost.Quality and Materials: OEM filters are made by Komatsu or approved manufacturers, ensuring they meet the company's strict design and quality standards. They are built to last and offer optimal filtration capabilities, protecting sensitive machinery parts like engines and hydraulic systems.

Automotive injector failure can occur due to various reasons that impact the performance and reliability of the vehicle. Some common causes of automotive injector failure include the use of unqualified or contaminated oil, damage to the sensor coil, wear of the internal structure of the injector, failure of the electronic control module, leakage from the injector or clogging of the nozzle, improper fuel pressure (either too high or too low), and loose or damaged connections to the injector.When faced with automotive injector failure, it is crucial to address the issue promptly.

Injector spray atomization and the shape of the oil beam on the engine work has a great impact, if the oil cambium shape is reasonable, atomization effect is good, then the engine will get a good cold start, smooth idling, less emissions effect.

The fuel injection pump is a core component of the engine, making daily maintenance critical. When the fuel injection pump malfunctions, how should it be repaired? In the following, I will explain common fault cases and troubleshooting methods for excavator fuel injection pumps.Fault 1: Diesel mixing with engine oil. This issue is typically caused by wear of the injection pump, manifested by an increase in oil volume with a strong diesel odor.
