Internal Combustion Engine

 

Ratings

Overall Rating:

4 stars
Content Quality: 4 stars
Effectiveness: 5 stars
Ease of Use: 4 stars
Reviewed: Sep 27, 2002 by Engineering Editorial Board
Overview: The site contains pertinent discussions and 21 applets that perform simple
calculations for analyzing internal combustion engines (ICE). It is divided into
three analysis areas of ICE performance: heat transfer, thermodynamics and
fluid mechanics. The Engine Performance applets under the Thermodynamic section
are the most involved. The heat transfer applet presents some fundamental
concepts on the modes of heat transfer in relation to ICE.
Learning Goals: To analyze the heat transfer, thermodynamics, and fluid mechanics principles of
internal combustion engines.
Target Student Population: Undergraduate Mechanical Engineering students. This site was developed to be an
addition to a senior level internal combustion engine class.
Prerequisite Knowledge or Skills: Basic knowledge of heat transfer, thermodynamics, and fluid mechanics.
Type of Material: Java Applets that can be used for lecture/presentation.
Recommended Uses: The material can be used as either a classroom demonstration or a self-tutorial
to teach various topics in thermodynamics, fluid mechanics, and heat transfer as
they apply to internal combustion engines. It can be used in teaching a
technical elective course in internal combustion engines and also as a reference
tool for design purposes.
Technical Requirements: Web access with a browser that supports Java applets.


Evaluation and Observation

Content Quality

Rating: 4 stars
Strengths: The presentation of fundamental concepts in thermodynamics and heat transfer
applied to internal combustion engines. The material makes effective use of
graphics to represent simulation results for analysis.
Concerns: The fluid mechanics applet could be expanded.

Potential Effectiveness as a Teaching Tool

Rating: 5 stars
Strengths: The material can be integrated into a mechanical engineering curriculum, and
good learning assignments that use the material can be written easily. The
applets are well organized into the areas of thermodynamics, heat transfer and
fluid dynamics. The heat transfer applets would be excellent additions to any
introductory heat transfer course.
Concerns: None

Ease of Use for Both Students and Faculty

Rating: 4 stars
Strengths: Navigation of the many objects contained on the website is very intuitive and
simple. Only minimal instruction is needed to become familiar with all of the
applets.
Concerns: The acceleration applet could not be accessed from the vehicle power
requirements link, but could be accessed from the main fluid mechanics page.
