Medium Speed Diesel Engines for Sea Transport Cost Reduction

A Finite Elements Procedure for Evaluating Injectors Reliability of Medium Speed Diesel Engines

A kind of injection nozzle manufactured since 1990 and utilized for ten thousands of motors, has recently showed a series of failures. These failures have happened only in one naval equipment and during a short period of time. In any case an uncertainty relative to sizing criteria arose. With reference to this problem, in the present work a methodology for performing a more careful structural a...

Diesel engines for light-to-medium helicopters and airplanes (Editorial)

Particle formation, deposition, and particle induced corrosion in large-scale medium-speed diesel engines

The objective of this work was to study the formation of particles and their morphology and chemical composition in large-scale diesel engines operating with low-grade residual fuel oils. The effect of a Mg-based fuel oil additive on exhaust gas particles was also investigated. Particle characteristics were determined by means of the methods of aerosol technology, chemical analyses, and electro...

Combustion Modeling for Modern Direct Injection Diesel Engines

In order to comply with stringent pollutant emissions regulations, a detailed analysis of the engine combustion and emission is required. In this field, computational tools like CFD and engine cycle simulation play a fundamental role. Therefore, the goal of the present work is to simulate a high speed DI diesel engine and study the combustion and major diesel engine emissions with more deta...

technologies for High Power density diesel Engines

The engines used in armoured fighting vehicles have to be compact, light in weight, efficient and reliable. In order to achieve a compact engine design, a complete understanding of all the factors affecting the engine performance is needed. However, it is important to note that the performance of the engine cannot be compromised in the pursuit of compactness. The aim of this paper is to classif...
