OPTIMISING THE REGULATING SYSTEM OF SUPERCHARGED DIESEL ENGINES

摘要

Increasing the performances of supercharged Diesel engines and reducing their specific fuel consumption and environment pollution suppose not only the application of some efficient constructive solutions, but also the improvement of their control and adjustment, otherwise the above goals cannot be reached. The present paper forwards an original concept and several solutions related to the optimisation of the regulating system's characteristics with the PGAV governor for supercharged Diesel engines equipping diesel-electric locomotives or variable pitch propeller ships. In this respect we presented the calculus algorithm and computer software used for the numerical simulation of the PGAV Woodward governor with the purpose of determining an optimised governor characteristic.
