POTENTIALITY OF THE MODIFICATION OF ENGINE COMBUSTION RATE FOR NO SUB X FORMATION CONTROL IN THE PREMIXED SI ENGINE

In order to study the potentiality of the modification of the combustion rate for NO formation control in the spark ignition (SI) engine, the authors first developed a new mathematical model by assuming the stepped gas temperature gradient in the cylinder. The predicted results from this new mathematical model show good coincidence with the experimental data. Second, the authors discuss the effects of the modification of the combustion rate on NOX formation using the new mathematical model. It was concluded that NOX formation in the premixed SI engine would be essentially determined by the specific fuel consumption only, regardless of any modification of the engine combustion rate. /GMRL/
