SOME RESULTS OF A STUDY ON THE OPERATION OF A HIGHLY SUPERCHARGED ENGINE AT VARIOUS RATES ON MOTION IN THE CYLINDER,

Abstract

The best economy in highly supercharged engines is achieved with Hesselman type combustion chambers. The article investigates problems of the effects of air charge gas dynamics on the operation of a 4-cycle, highly supercharged engine with a cylinder diameter of over 200 mm. All three air velocity components are analyzed; axial, radial and tangential. The analysis makes use of oscillograms produced at idling to determine tangential air velocity in the cylinder before the beginning of combustion to determine the influence of screened valves, analyze coefficient of admission and means pressure of pumping cycles for valves with and without screens and show the variation of principal engine operation indicators for various sprayer-atomizers, etc. (Author)
