Work Proposal


  • Most members of the group have some experience with a CAD package, this should allow our modeling expert to delegate tasks during the modeling in order to speed things up.
  • The technical expert has an excellent understanding of car engines, this should make product disassembly and reassembly go quickly and smoothly. Other members of the group are familiar with the tools required and are familiar with basic product tear down procedures. This should prove greatly helpful to the technical expert during dissection.


  • Only one team member has a working knowledge of internal combustion engines. While this does make him an asset to the group, without him present during the dissection we could run into problems identifying parts or disassembling them.
  • We have a large and complex engine with many pieces, keeping everything organized could become a problem during dissection and reassembly. A number of different bolt lengths, threads and head sizes are used, keeping careful track of each variant is very important.
  • None of the group members have experience creating or editing a Wiki page, so our Wikipage Designer will have to learn many new things as the needs present themselves.

Plan for Dissection
Regardless of the number of parts, dissection of any product follows the same procedure; remove each piece in the order which they are available. We plan on disconnecting everything that we have access to, and then disconnecting the pieces which are exposed. In this way we will eventually disconnect every part from its neighbors. This is, of course, a simplification of the actual process required to dissect an engine but it conveys the basic concept of how product dissection occurs. Throughout the process we will be labeling and keeping track of parts, regardless of size and shape. Every piece connects to its neighbors in a specific way and the multitude of bolts are not all the same length or threading. A variety of tools will be needed for this endeavor, see below for the list of tools.

Necessary Tools

  • Engine Mount - Without a means of elevating the engine and rotating it this project would be nearly impossible. Certain pieces of the engine are secured to the bottom of other pieces, so without access to the bottom of the engine we would never be able to fully dissect the product.
  • Socket Wrench - A socket wrench with a set of hex sockets is absolutely essential. Every bolt we have located is a hex bolt, ranging from 8mm to 16mm.
  • Crescent wrench - Some locations it may be simpler and easier to use a crescent wrench rather than a socket wrench, having the correct sized crescents available could be invaluable
  • Mallet - Some force is required to separate press fit parts such as the bearings on the crankshaft and connecting rods for the pistons/
  • Pliers - In some cases parts may want to turn which are supposed to remain stationary, in which case pliers would allow us to prevent or force motion as needed.

Management Proposal

An important step in any project is estimating the amount of time required to complete each step and figuring out how to fit all of that work into the period available for the project. To this end we created this Gantt chart, detailing each of the steps and when that step is to be completed. Another important thing is organization. Our group meets on Monday, Wednesday, and Friday from 4:50-5:00pm to discuss where each member is with his assigned tasks and figure out who will be working on what in the future. We communicate mostly via email, with phone calls and text messages used in the case of time-sensitive questions.
