STUDIES OF COMBUSTION IN STRATIFIED CHARGE ENGINES

UNTERSUCHUNGEN UEBER DIE VERHRENNUNG IN SCHICHTLADUNGS MOTOREN

The multiplicity of parameters which govern the design and tuning of stratified charge engines makes many different solutions possible. All the arrangements so far proposed are reviewed according to a rough classification of the salient characteristics. The influence of the main variables (spark plug location, subsidiary chamber injection, ignition timing and inlet air control) on the efficiency and exhaust emission of a stratified charge engine with subsidiary chamber injection are discussed and compared with the conventional otto cycle. The higher NO emission of the otto motor is noted and compared to the results from other stratified charge designs. The theoretical analysis of NO formation is illustrated by graphs. Engines with subdivided combustion chambers promote a high degree of stratification and considerable reduction of NO emission. Further charge stratification may be achieved by means of subsidiary chamber injection resulting in even greater efficiency. All the various stratification methods enable the design of internal combustion engines to be adapted to contemporary efficiency and emission requirements. Because of the multiplicity of the parameters their influence and relationships have not been fully established, so that further progress in this field is both possible and desirable. /TRRL/
