STUDY OF NEW TYPES OF LOW-NOISE ENGINES TO DETERMINE RELATIONS BETWEEN NOISE AND PARAMETERS ASSOCIATED WITH THE CASING

UNTERSUCHUNG AN NEUARTIGEN GERAEUSCHARMEN MOTOREN UEBER DIE ZUSAMMENHAENGE ZWISCHEN DEM GERAEUSCH UND DEN DIE VERSCHALUNG BETREFFENDEN PARAMETERN

THE OBJECT OF THE RESEARCH CONSISTS IN COLLECTING BASIC INFORMATION ON THE OCCURRENCE OF NOISE IN THE NEW GENERATION OF ENGINES AND ON THE INFLUENCE OF VARIOUS PARAMETERS. THE NEW LOW-NOISE ENGINE, WHICH IS THE RESULT OF PREVIOUS WORK, IS CHARACTERISED BY THE BODY NOISE INSULATION OF ALL THE PARTS WHICH FORM THE SURFACE OF THE ENGINE AS OPPOSED TO THE ACTUAL ENGINE ITSELF. THE REALISATION OF THIS PRINCIPLE LED TO A CLOSED EXTERNAL CASING, WHICH IS SUPPORTED AT A FEW POINTS BY FLEXIBLE SOUND-DAMPING ELEMENTS INSIDE THE ENGINE. THIS CLOSED EXTERNAL CASING MAY BE USED AS A SUBSEQUENT MEASURE TO SURROUND A CONVENTIONAL ENGINE, AND MAY ALSO BE INTEGRATED INTO THE DESIGN OF THE ENGINE, IN CERTAIN CASES CLOSING OFF THE LUBRICATION AREA FROM OUTSIDE. GENERAL VALID DATA ARE TO BE COLLECTED FROM THE RESULTS OF THE WORK SO THAT IN THE CONSTRUCTION OF THE NEW LOW-NOISE ENGINES IT WILL BE POSSIBLE TO ACHIEVE ECONOMIC DESIGN AND SELECTION OF MATERIAL FOR THE CASING.
