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.

Injector troubleshooting methods1. Few or no oil injected by the injector.2. Injector injection pressure is too low.3. Injector injection pressure is too high4. Leakage of fuel injector injectors5. Poor atomization of fuel injector injection6, Injector injection into the line7, Injector needle valve surface burned or blue-black color. Note: (diesel engine overheating) check the cooling system, and pay attention to the replacement of coupling parts.

Recently, the Novokuznetsk Mining and Coal Exhibition was held in Novokuznetsk, Russia, from June 4 to 7. As a leading company focusing on the field of machinery parts, Jining Huida Construction Machinery Co., Ltd. was honored to attend the exhibition on behalf of Chinese suppliers. In this event, we have demonstrated the excellent quality and innovative strength of Made in China with impressive achievements, which has won more praise for our company in the global market!The exhibition venue exhibition area of 55,000 square meters, nearly 30,000 visitors, as many as 600 exhibitors and brands.

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.

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.

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.
