Course Description
Background InformationThe ideal cycle for a simple gasoline engine is the Otto Cycle. In this course material, the open, simple Otto Cycle used for stationary power generation and combustion are presented.
For Otto Cycles, only air is used as the working fluid.
When dealing with combustion, six different fuels (carbon, hydrogen, sulfur, coal, oil and gas) react with air and oxygen enriched air as the oxidant at different stoichiometry values (stoichiometry => 1) and oxidant inlet temperature values.
For Otto Cycles, thermal efficiency derivation is presented with a simple mathematical approach. Also, p - V and T - s diagrams and power cycle major performance trends (thermal efficiency, specific power output, power output, combustion products composition on weight and mole basis, specific fuel consumption and stoichiometry) are plotted in a few figures as a function of compression ratio and combustion temperature. It should be noted that this course material does not deal with costs (capital, operational or maintenance).
The combustion technical performance at stoichiometry => 1 conditions is presented knowing the enthalpy values for combustion reactants and products, given as a function of temperature. For each combustion case considered, combustion products composition on both weight and mole basis, flame temperature, stoichiometric oxidant to fuel ratio and fuel higher heating value (HHV) are presented in tabular form and plotted in a few figures.
Course ObjectivesIn this course material, the student gets familiar with the ideal Otto Cycle and combustion and their p - V, T - s and h - T diagrams, operation and major performance trends.
At the conclusion of this course, the student will:
- Understand basic energy conversion engineering assumptions and equations
- Know basic elements of Otto Cycle and combustion and their p - V, T - s and h - T diagrams
- Be familiar with Brayton Cycle and combustion operation
- Understand general Otto Cycle and combustion performance trends
Continuing Education InformationWhen the student is done with the the Advanced Otto Cycle and Combustion Analysis course material, he/she needs to take a thirty (30) question quiz. Upon successful completion of the quiz, Professional (Licensed) Engineers will get 3 hours of credit.
Furthermore, upon successful quiz completion, Engineering Software will provide a copy of the Course Certificate in a PDF form either in an e-mail directly as an attachment and/or providing a URL for it; Engineering Software can always mail a copy of the Course Certificate to the student and/or mail it where it needs to go for the record.
Note: Students from Florida, Louisiana, New York and North Carolina states should consult their State Licensing Boards for pre-approval of all continuing education.
It is the responsibility of the individual learner to be sure that he or she is meeting continuing education requirements for each license and corresponding renewal period!
