Experimental Study on ATAC (Active Thermo-Atmosphere Combustion) in a Two-Stroke Gasoline Engine

Abstract

<div class="htmlview paragraph">The paper deals with experimental activity concerning ATAC, which, in two-stroke gasoline engines, helps solving the crucial problem of combustion instability at light loads. ATAC consists of employing the energy of residual gas to prime an efficient combustion.</div> <div class="htmlview paragraph">The research is aimed to give further insight into ATAC mechanism both by visualisation of the combustion process and by examination of the influence which relevant parameters like air-fuel ratio, engine speed, compression ratio, scavenging passage design have on ATAC operation.</div> <div class="htmlview paragraph">Several results have been acquired and collected hitherto. A part of them are shown and discussed in this paper.</div>
