Abstract	To effectively use fuel energy in internal combustion engines, the concept of Low Heat Rejection Engine (LHRE) has been developed over the past four decades. This concept that LHRE can increase an engine power output and efficiency has enabled further accomplishment of a broad array of research topics in this field. In this work, the various processes of the LHRE DI diesel engine were simulated with a developed multi-zone quasi-dimensional model and the results were compared with those derived from the base DI conventional engine. In the multi-zone model, the engine combustion chamber after fuel injection is divided in two zones: air zone and spray zone. After break up time, spray zone also divides into an axial direction and across it in radial direction. The governing equations that include mass, energy and simplified momentum equations were solved for each zone to obtain the pressure, temperature, equivalence ratio, and properties of the combustion products. In this study, the multi-zone two-dimensional model was developed to model insulated engine and also to predict the enhancement of the engine power.
