Ice Help
Application

The program may be used as a tool by Students, Engineers etc to evaluate and illustrate the potential performance of Two Stroke Internal Combustion Engines, hence the name ICE. It enables the user to establish the potential outcome of alternative design configurations. The output data is presented in tables with the option to display this in Graphical form or Diagrams, on Screen or to a Printer.

The program ICE (Internal Combustion Engine) does not give precise answers to all  engine functions. It is a powerful analysis tool to compare alternative configurations.

The features, which may be evaluated, are -
