Air Fuel Ratio Control in Liquefied Petroleum Gas Injected Si Engines

Chris Manzie, Harry Watson, Marimuthu Palaniswami Department of Electrical and Electronic Engineering Department of Manufacturing and Mechanical Engineering The University of Melbourne, Victoria, Australia, 3010 Abstract: Despite being one of the fastest growing alternative fuel sources, little attention has been given to control of the air fuel ratio at the point of combustion in liquefied pet...

Ion Current Simulation During the Post Flame Period in SI Engines

The application of ion current signals is one of the most recent approaches in engine management systems. By applying a small constant DC voltage across the electrodes of the spark plug and measuring the current through the electrode gap, the state of gas may be measured and investigated. In this paper a computer code is developed in order to analyze the state of gas during the combustion p...

Prognosis of Faults in Gas Turbine Engines

A problem of interest to aircraft engine maintainers is the automatic detection, classification, and prediction (or prognosis) of potential critical component failures in gas turbine engines. Automatic monitoring offers the promise of substantially reducing the cost of repair and replacement of defective parts, and may even result in saving lives. Current processing for prognostic health monito...

Anomaly Detection in Aircraft Gas Turbine Engines

Is Thermal Barrier Coating for Low Heat Rejection in SI Engines or Diesel Engines?

The diesel / gasoline engine rejects about two thirds of the heat energy of the fuel, one-third to the coolant, and one third to the exhaust, leaving only about one-third as useful power output. Theoretically if the heat rejected could be reduced, then the thermal efficiency would be improved, at least up to the limit set by the second law of thermodynamics. Low Heat Rejection (LHR) engines aim...
