  7. Abstract:
  8. Since the construction of the first models of internal combustion engines in the nineteenth century, efficiency and, since the late twentieth century, pollution and fuel consumption has been the main issue for researchers and manufacturers who have always sought to improve it. Manufacturers of internal combustion engines are required to perform numerous tests to carefully study and increase the level of technology and reliability of their products. There have been two ways for them to do this; the first way is to use the experimental method; that is, making multiple samples that require a high cost that makes it impossible. The second way is to use engine simulation software, which can be used to examine the existing processes in addition to reducing the costs associated with the design and testing of combustion engines. These modelings can be one-dimensional or multidimensional, which require engine operating conditions and geometry to solve the problem. In the present study, the performance of a carburetor Wankel engine has been investigated through computer modeling. Thermodynamic modeling by equating the rotary engine with a reciprocating engine according to the relationship between these two types of engines is done in GT-Power software and validated based on the data obtained from the experimental test of the rotary engine in standard environmental conditions. Then the valid model is used for simulation and parametric study in two separate parts; In the first part, the effect of operating environmental conditions on carburetor engine performance and comparing engine power using two alternative fuels, and in the second part, the effect of adding a turbocharger system is investigated and a suitable turbocharger is selected for the required operating conditions
