[0002] With the introduction of the Paris Climate Agreement and a series of international maritime regulations, higher standards have been set for emissions, fuel consumption, and other indicators of marine low-speed diesel engines. Electronically controlled, environmentally friendly low-speed diesel engines continue to attract widespread attention. With the continuous optimization and upgrade of main engine emissions and fuel consumption, diesel engine development is gradually moving towards automation and intelligence. Hydraulic oil is a critical component of electronically controlled main engines. Due to the special characteristics of the precision sealing structure within hydraulic components, certain cleanliness requirements are required for the hydraulic oil. Failure to do so will affect the sensitivity of the hydraulic oil control valve, resulting in the malfunction of the marine low-speed diesel engine. Therefore, the hydraulic oil must pass through a high-pressure filter to ensure that the hydraulic oil reaches the required cleanliness level and can continuously provide power for injection and exhaust.
