Algebraic Modeling for Thermodynamic Study of the Compression-Ignition Engine 2005-01-4143
In this work an algebraic model for the thermodynamic study of the compression-ignition engine is developed using the concept of efficiencies in the processes that compose the air standard cycle. In this model, the use of the efficiency concept added to the variation of the specific heat, the heat release based on Wiebe function, and variation of the initial instant of heat release and heat rejection, makes this no ideal cycle to approach the actual Diesel operation. A cinematic model of the crank-and-connecting rod mechanism is used to transform the gas work in axis torque. This model serves as didactic tool for the thermodynamic analysis of the compression-ignition engines operation.
