Type 59 --- ENGIPLSI ==================== NUMERICAL SIMULATION OF A GAS ENGINE IN PART LOAD REGIEME Routine ENGIPLSI deals with the part-load operation of a Spark Ignition Engine. The shaft power is assumed to be reduced by a controlled throttling before the carburator. It is also assumed that the engine is maintained at a certain stand-by rotation speed when no shaft power is demanded. This stand by rotation speed is an additional parameter. Input, Output and Parameter descriptions are in the *.for file. For More details, see the HVAC1KIT manual. For a complete description of the routine, reference the HVAC1KIT manual, prepared by; Jean Pascal BOURDOUXHE and Marc GRODENT, Research Assistants. Jean LEBRUN, Principle Investigator.
