Characteristics of unsteady total pressure distortion for a complex aero-engine intake duct

Effect of Direct Injection Diesel Engine Convert to Sequential Injection CNG Engine in Intake Port Gas Flow Pressure Profile

The one dimension computational model of a sequential injection engine, which runs on compressed natural gas (CNG) with spark ignition, is developed for this study, to simulate the performance of gas flow pressure profile, under various speed conditions. The computational model is used to simulate and study of the steady state and transient processes of the intake manifold. The sequential injec...

Robotic Assembly of Aero - Engine Components

The VITAL (EnVIronmenTALly Friendly Aero Engines) project funded by the European Commission under its Framework 6 Programme aims to provide significant reductions in fuel burn, emissions and noise through the development of innovative design and manufacturing techniques. One way to reduce the amount of fuel burnt, and hence CO2 produced, is to reduce the weight of the engine. A significant prop...

Failure analysis of an intake valve in a gasoline engine

This paper presents a failure analysis on a failed intake valve in a gasoline engine. During an endurance test, an intake valve was broken and caused some damages on the piston. Material examinations (by a light microscope and also a scanning electron microscope) were conducted on the fracture surface of the intake valve shaft. Results showed that no pores or defects could be observed and the m...

Aero-Engine Adaptive Fuzzy Decoupling Control

A new kind of multivariable adaptive fuzzy decoupling controller is present for Aero-engine, which consists of multivariable fuzzy decoupling control and fuzzy model reference learning control. A fuzzy inverse model is used to produce and adjust fuzzy rules online. The simulation results show that this controller is effective.
