Future System for High-Pressure Fuel Leakage Detection in Marine Commercial Engines

Abstract

The project explores the development of novel double-walled high-pressure fuel injection pipes used in marine commercial engines. Current double-walled pipes meet the safety standard, but they suffer from higher costs and increased manufacturing complexity. The project aimed to offer the industry a superior alternative to existing solutions in certain Volvo Penta engines, with the intent of improving the manufacturability of the components, reducing costs, and improving tolerances. The project was driven towards developing a robust leak detection and containment mechanisms to mitigate hazards such as fuel spray or contamination in the engine room. It also investigates on potential suppliers for procuring the materials and components for the system. It also aims to propose recommendations for future systems. The project was conducted using a stage gate product development process. Initially, an analysis of existing systems and Volvo Penta marine engines was performed, followed by a review of the regulations applicable to current engines, as these regulations played a major role in the concept development. The final design was validated through Finite Element Analysis (FEA) while cost calculations were performed and material alternatives were explored.
