Discussion on the Frequent Burning and Erosion of Marine Medium-Speed Diesel Engine Valves: A Case Study of MAR 8N330 Diesel Engine

Abstract

In the practice of ship management, valve burning and erosion is a common and adversely affecting incident, which can lead to a series of serious consequences. This article analyzes the frequent burning and erosion of medium-speed diesel engine valves from seven aspects: the harsh working conditions of the valves, the impact of environmental temperature, the impact of cylinder sealing status, the corrosion of valves by low-quality fuel oil, the influence of the intake and exhaust system, the impact of high or too low load operation, and the influence of valve clearance and sealing surfaces. Corresponding prevention and control measures are proposed. This provides beneficial ideas and reference for decision-making for engine room personnel to smoothly handle valve burning and erosion faults and ensure the safe navigation of ships.
