Internal Combustion Engines

Spring 2004

Clean diesel combustion technology, like this Low Emission Diesel Engine, uses innovative air, fuel, and combustion management and conventional particulate matter aftertreatment to achieve lower NOx levels without the need for NOx aftertreatment.

Course Highlights

This course features  homework assignments, labs and an extensive reading list.

Course Description

This course elaborates on the fundamentals of how the design and operation of internal combustion engines affect their performance, operation, fuel requirements, and environmental impact, study of fluid flow, thermodynamics, combustion, heat transfer and friction phenomena, and fuel properties, relevant to engine power, efficiency, and emissions, examination of design features and operating characteristics of different types of internal combustion engines: spark-ignition, diesel, stratified-charge, and mixed-cycle engines. The project section details the Engine Laboratory project. We have aimed this course for graduate and senior undergraduate students.

Homework Policy

  1. The purpose of the homework and problems is to get each of you to think about and use the material we discuss in class.
  2. Obviously, I want each of you to make a serious try at each problem. If discussions with other students help you get started, then contribute to and benefit from such discussions.
  3. However, I expect that each of you will work independently on the details of the problem solutions which you hand in as your work. I regard it as dishonest to copy from any previously circulated solutions and present such work as your own.
  4. If you have any questions about the above, please discuss them with me.
