Engineering Analysis

The most important part of the snow blower would have to be the engine since this is what powers both the linear drive and auger drive. Therefore, it would be crucial to determine the thermal efficiency of the engine during the design/testing stages of the design process. By determining the maximum potential efficiency of the engine in design, designers are able to gauge whether the engine performance is acceptable and make adjustments accordingly. Below is an example of what how the engineering analysis applied to this task may look like.

Problem Statement

Determine the thermal efficiency of the 4 stroke engine in design.

Given:

• Volume in combustion chamber with piston at highest point
• Volume in combustion chamber with piston at lowest point
• Temperature inside combustion chamber
