Group 19 - Honda Engine
Our group, Group 19, has been tasked with disassembling a Honda engine. Our engine is an inline four cylinder. This means that it contains four cylinders and pistons adjacent to one another. We plan to start disassembly at the top in the air filter and work downward. This seems like the easiest approach, as the air filter will yield way to the cylinders of the engine. Figure 1 shows the top view of the engine. We then plan to disassemble the cylinders and make way through to the crank shaft. There are a widespread number of tools that may be necessary to help disassemble the engine. The outermost parts of the engine are simple enough to disassemble. Standard screw drivers and a ratchet can mostly be used to remove casings, and pliers can be used to remove most hoses without a problem. For the internal parts, vice grips and WD-40 may be used to remove some jammed components that are better set into place. Figure 2 shows a more detailed breakdown of the tools and possible uses.
|Metric Ratchet Set||Removing bolts from the casing/internal components|
|Metric Screw Driver Set||Removing screws from the casing/internal components|
|Metric Allen Keys||Removing Allen head screws from the casing/internal components|
|Metric Torx Screw
|Removing Torx head screws from the casing/internal components|
|Pliers||Removing hoses and clamps|
|Needle Nose Pliers||Removing small clamps|
|Vice Grips||Holding loose components to the engine|
|Hammer/Mallet||Removing attached/rusted on components|
|WD-40||Loosening components that may be difficult to move after setting|
This dissection is expected to take approximately 10 hours. Five hours would be used to disassemble the product. Two and a half hours would be dedicated to understanding the internal components and their functions. The final two and a half hours would be spent reassembling the engine properly.
There are several large challenges involved in the disassembly of the engine. Firstly, there are many small parts and components that we are unfamiliar with. This will make it difficult to understand how it works. Additionally, we found that the engine itself has a highly intricate design. This coincides with the first obstacle, meaning that the high degree of complication will make understanding the inner workings of the engine difficult. The last impediment we found was that the engine is heavy. Being unable to physically manipulate the entire product makes dissection difficult, as some components may be in hard to reach places.
Our group has a small arrangement of capabilities among our members. John Burkhart has some limited solid modeling experience that will need to be supplemented to complete the project. All members are able to operate a computer, as well as most tools and equipment we will be using to disassemble the engine. In addition, all members of our group have AutoCAD experience, and are able to use that as a possible presentation tool.
Our group also has several disadvantages. No members of our group have ever made a Wiki, meaning that someone will have to take time to learn how to develop and maintain one. Also, none of our group members have any automotive experience. This lack of knowledge will hinder our group in identifying the components of the engine.
