Comprehensive Correlation for the Prediction of the Heat Release Characteristics of Diesel/CNG Mixtures in a Single-Zone Combustion Model

Fuel combinations with substantial differences in reactivity, such as diesel/CNG, represent one of the most promising alternative combustion strategies these days. In general, conversion from diesel to dual-fuel operation can be performed existing in-use heavy-duty compression-ignition engines minimum modifications, which guarantee very little particles, less nitrogen oxide (NOx), and reduced noise by half compared diesel. These factors make it feasible retrofit a CNG fuel system on an engine operate dual mode. However, single-zone models using traditional single-Wiebe function are exceptionally adopted assess dedicated engines, whereas heat loss walls is estimated Woschni formulation. It means that fast preliminary analysis unmodified performance 1-zone becomes complicated due obvious deterioration energy parameters, which, turn, was predetermined deviation thermodynamic cycle variables calculation outcome. this study, main novelty lies fact we propose novel composition-considered correlation for prediction release duration characteristics diesel/CNG mixtures engine.
