瑞士温特图尔发动机有限公司（WinGD）推出了一套新的发动机诊断解决方案，将在由贝仕船舶管理公司（BSM）运营的一艘液化天然气（LNG）运输船上开展试验。该船配备有两台WinGD 5X72DF 二冲程发动机，试验装置将监测对发动机运行至关重要的五个部件——气缸套、活塞环、排气阀、燃油泵和燃油喷射器的工况，运用算法评估它们的剩余使用寿命，并制定合适的维护周期。这一名为WiDE的发动机诊断系统能够为船员诊断发动机故障并给出可能的原因，提醒船员进行维护保养。该技术是实现二冲程发动机智能预测性维护的重要一步。

        Swiss marine power company WinGD has launched a pilot project for a new engine diagnostics solution that will be trialled on a vessel managed by Bernhard Schulte Shipmanagement (BSM). The trial vessel is a BSM-managed LNG carrier with two five-cylinder WinGD X72DF engines. The pilot installation will monitor five of the engine components crucial for reliable engine operation (cylinder liners, piston rings, exhaust valves, fuel pumps and fuel injectors), recommending condition-based maintenance intervals by using algorithms to estimate their remaining useful life. Through WiDE’s engine diagnostics system, crew on the vessel will be provided with the possible causes to diagnose faults and prompted to add relevant maintenance tasks. The technology is an important step to enable smart, predictive maintenance for two-stroke engines.

Tips：燃油泵是供油系统中使用的一种泵，用于克服燃油滤清器的液压阻力，并在滤清器的液压因污垢而升高时稳定供应给高压泵的燃油量。燃油泵将燃油从燃油箱中吸出、加压后输送到供油管中，和燃油压力调节器配合建立一定的燃油压力。油泵分为内置式（浸在汽油箱的的汽油中）和外置式（布置在汽油箱外），一般采用内置式。船用柴油机一般配备低速油泵，约620转/分。
