... of the different zones. Thus, the model is not predictive but diagnostic: The objective is to interpret measured engine data in order to obtain insight into the in-chamber combustion and pollutant formation processes. The model has been tested on EGR-sweeps and under full-load conditions on the conventional engine...

...Craig R. Davison; Chris Drummond Statistically based metrics, incorporating operating costs, for gas turbine engine diagnostic systems are required to evaluate competing products fairly and to establish a convincing business case. Diagnostic algorithm validation often includes engine testing...

... diagnostic information for current and future diesel engines. The remainder of this paper describes new results using an improved apparatus and focuses on measurements of smoke levels below 1 FSN. Correlation between first generation smoke sensor signal and filter smoke number (1000 rpm, 3.25 bar BMEP...
