Characteristics of the Perkins ‘Squish Lip’ Direct Injection Combustion System 780113
This paper describes the application of a novel combustion chamber of re-entrant form to a high speed direct injection diesel engine. A parametric study with the major dimensions of the chamber as variables shows the relationship between oxides of nitrogen, specific fuel consumption and smoke emission. Control of pollutants is demonstrated at retarded injection timings without significant deterioration in performance. The major factors affecting hydrocarbon emission are presented and the combustion system is shown to comply with the most stringent exhaust emission legislation yet proposed.
