The Fundamental Research of Combustion in the Stratified Charge Engine With An Auxiliary Chamber 785096
The major features of the stratified charge engine with an
auxiliary chamber are: (1) the mixture in the combustion chamber
has concentration gradient due to the auxiliary chamber and (2)
turbulent flame is injected into the main chamber. The objective of
this research is to examine those effects upon the combustion
characteristics and the burned gas composition. The characteristics
of flame propagation were examined by using a series of schlieren
photographs.
A summary of the major conclusion of this research is given
below:
(1) The mixtures supplied in the main and the auxiliary chambers
burn without mixing with each other.
(2) The concentrations of HC and CO decrease as the closer the
mixture in the auxiliary chamber approaches stoichiometry and the
leaner the mixture in the main chamber. The concentration of CO
decreases as the torch opening area decreases.
(3) The concentration of NOx decreases as the mixture in the
auxiliary chamber becomes richer, the mixture in the main chamber
becomes leaner and the torch opening area becomes larger.
