PARAMETERS AFFECTING IN-CYLINDER SOOT AND NOX FORMATION IN A DIRECT INJECTION DIESEL ENGINE
A spectroscopic method to determine in-cylinder flame temperature and soot concentration was combined with in-cylinder NOx-modelling to study the influence of operating conditions and combustion system parameters on the formation of soot and NOx in a low-emission single- cylinder direct-injection diesel engine. Fuel consumption and emissions are compared with time-resolved combustion analysis data. (A) For the covering abstract see IRRD 869246.
THE INVENTION CONCERNS A CONTROL CIRCUIT FOR ANAEROBIC REACTOR SYSTEM. THE TOUR INCLUDES FILTER 16 ESTIMATE THAT RECEIVES INPUT SIGNAL SENSOR PRODUCTS AN ESTIMATE OF THE PRESENT VALUE A VARIABLE IN THE SYSTEM, COMPARE THAT ESTIMATE FOR A SIGNAL SENSOR THE VARIABLE AND PRODUCT OF THAT COMPARISON, SIGNAL ERROR dIFFERENCE IS TO COMBINE THE RECEIVED SIGNAL and reapplied INTEGRATOR, A DISPOSAL OF A BIAS LONG TERM THAT MAY BE PRESENT IN AT LEAST ONE OF SIGNALS rECEIVED, SUCH ELIMINATOR INCLUDING HIGH PASS FILTER BY 53 OR rECEIVED INPUT SIGNALS ARE TRANSMITTED TO THE iNTEGRATOR 58, SUCH FILTER HIGH PASS THAT REJECTING THE BIAS PERSISTS FOR A PERIOD CONSIDERABLY LONGER THAN THE TIME cONSTANT SYSTEM. APPLY THE iNVENTION INCLUDING THE TREATMENT OF WASTE WATER.
