The internal combustion (IC) ee is a heat ee that converts chal energy in a fuel into mechanical energy, usually made available on a rotating output shaft. Chal energy of the fuel is first converted to thermal energy by means of combustion or oxidation with air inside the ee. This thermal energy raises the temperature and pressure of the gases within the ee, and the high-pressure gas then expands against the mechanical mechanisms of the ee. This expansion is converted by the mechanical linkages of the ee to a rotating crankshaft, which is the output of the ee.
The main focus of this course is on the application of the eeering sciences, especially the thermal sciences, to internal combustion ees. The goals of the course are to familiarize the student with ee nomenclature, describe how internal combustion ees work, and provide insight into how ee performance can be modeled and analyzed.
In this course, we discuss the eeering parameters that are used to characterize the overall performance of internal combustion ees. Major ee cycles are covered such as Otto, Diesel, Dual and Miller cycles. The following lectures will apply the principles of thermodynamics to detee temperatures and pressures throughout an ee cycle, in addition to important ee performance parameters such as: Indicated Thermal Efficiency and the Indicated Mean Effective Pressure. Also we investigate the dependence of ee performance on ee compression ratio and ee load.
An aspect upon which we have put considerable emphasis is the process of constructing idealized models to represent actual physical situations in an ee. Throughout the course, we will calculate the values of the various thermal and mechanical parameters that characterize internal combustion ee operation.
My goal in this course is to help students acquire a solid theoretical background of internal combustion ees. Solved numerical examples are used extensively in this course to help students understand how theory is applied to analyze practical applications.
