AI Technical Summary

Technical Problem

During operation, marine turbocharged intercooled engines may experience abnormalities in parameters such as intake air temperature, intercooled air temperature, and boost pressure, leading to changes in the amount and temperature of air in the cylinder and affecting engine reliability. Therefore, a health management method needs to be designed to identify and address risks in a timely manner.

Method used

By monitoring engine operating parameters such as intake air temperature, circulating oil volume, and engine speed, the system calculates the baseline boost pressure and determines whether the real-time boost pressure is within the allowable range, generating alarm signals and issuing fault prompts to remind users to address potential risks.

Benefits of technology

It enables real-time monitoring and fault diagnosis of turbocharged intercooled engines, protecting the engine's reliable operation and avoiding greater risks, without the need for additional parts. Real-time monitoring is achieved through test bench calibration or simulation calculation.

Abstract

本发明公开了一种发动机健康管理方法,先获取进气温度、循环油量和发动机转速,查得基准增压压力和增压压力修正值,计算出修正后基准增压压力,再获取实时增压压力和许用增压压力偏差,然后判断发动机是否运行在稳定工况常规环境下;若运行在稳定工况常规环境下,再判断实时增压压力P是否在[P1‑P2,P1+P2]区间之内,若P不在区间之内,发出对应的故障提示。可见,本发明通过对发动机运行过程中运行参数的监测诊断,来实现冷却水滤器、空气滤清器、进气管路、排气管路、增压器等零件工作情况的实时监测,并根据实际监测情况发出故障提示、降负荷运行等,以提醒用户提前识别风险并处理,避免更大使用风险,保护发动机可靠运行。
