Engineering Analysis -(Group 10) 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. Determine the thermal efficiency of
the 4 stroke engine in design. - Volume in combustion chamber
with piston at highest point - Volume in combustion chamber with
piston at lowest point - Temperature inside combustion chamber -
Any energy lost to friction is negligible - Engine is based on
Otto cycle (ideal case for 4 stroke engine) - Air acts as an
ideal gas - Only fuel/air present in the fuel/air mixture used
for combustion - No unintended
