The functioning of the engine in a closed loop with lambda sensor and catalyzer makes the excess air factor to be maintained as close as possible to the value 1=1. Based on an own model, the authors realized an analytical calculation of the indicated diagram. The indicated diagram was also raised on an experimental stand in p-V coordinates, and the real indicated diagram in p-a coordinates. The equations for the thermal processes that take place in the engine have been determined and, after that, these were introduced in a computer. Using these equations, the state parameters in the characteristic points of the engine cycle were calculated.

This paper presents the numerical results of a simulation of the thermodynamic cycle for in spark ignition engine (SI) in normal external conditions (T 0 =293 K; p 0 =10 5 Pa) and revolution n=5500 rpm, at full charge. The simulation took in account the constraint for =1, for air pollution reduction whit combustible gases This paper presents the numerical results of a simulation of the thermodynamic cycle for in spark ignition engine (SI) in normal external conditions (T 0 =293 K; p 0 =10 5 Pa) and revolution n=5500 rpm, at full charge. The simulation took in account the constraint for =1, for air pollution reduction whit combustible gases [1]. The indicator diagram was calculated in p-V coordinates, and in p-α coordinates. Equations for thermal processes that take place in the engine were determined and then entered into a computer program. Using these equations, the state parameters were calculated at the characteristic points of the engine cycle. The research was conducted in order to obtain information that could be used improving the characteristics of an engine SI. The operating mode of the engine is defined by the speed of rotation and load, but it involves knowledge, in addition to these, of the thermal regime (parts temperature, cooling fluid temperature, intake air temperature, exhaust temperature, altitude corrections and etc.). The logic diagram of the calculation program is presented. The calculation program for determining the indicator diagram is done in Mathcad, both for the low pressure area and for the high pressure. The engine stand and the pressure transducer with their characteristics are presented. The diagrams are shown in p-V and p-φ coordinates. The p-V indicator diagrams are calculated by the presented program based on data measured on the engine stand.. The indicator diagram was calculated in p-V coordinates, and in p-α coordinates.
