 Based on the nature of our product and the fact it has quite a few moving parts, fairly precise models would need to be made in order to evaluate the product.  In terms of various models that would need to be analyzed, analytical ones would be the most important and beneficial but graphical models would also be useful.  These graphical models can be in the form of CAD drawings, or 3D modeling such as Solid Works.  While these models are helpful the most important are the analytical models such as fatigue, power transmission, thermodynamic, stress/strain as well as others.  With our product being an engine many of these models need to be performed and analyzed before the engine is manufactured on a large scale.
-Fatigue models would need to be performed on various parts of the engine such as the cylinder walls, pistons, piston rings as well as the engine block itself.  These are necessary because if some of these parts fail the whole engine could fail.  For example if any of the rings fail the engine could either lose compression or oil could leak into the combustion chamber and cause the engine to burn oil.  Also, power transmission models would need to be analyzed to look at how power is transferred from combustion to the pistons, then to the crank shaft then to the blades.  Along with the power transformations, possible power losses would need to be tested.  Thermodynamic/heat transfer models would also have to be tested and analyzed because our engine being internal combustion it creates a lot of heat.  The engine block itself has “fins” on it in an attempt to dissipate heat.  For engineers to know whether these fins properly dissipate heat or dissipate enough of it these models need to be looked at.  Fluid flow models, while not as important as the others would also need to be analyzed.  The only model that would need to be looked at would be the transfer of fuel from the tank to the carburetor.  A rubber hose connects these two components and would need to be tested to ensure proper flow as well as is there were possible restrictions such as a kink.  Lastly and possibly the most important model that would need to be tested would be the materials stress/strain model.  There are various different components in our engine that are made of different materials.  Each of these components has a different use and some need to be able to handle certain stresses and strains.  For example, our engine block is made of cast iron.  This is so because with the engine block being internal combustion the block needs to be able to handle higher stresses and strains.  This piece as well as other various components needs to be tested numerous times and for long period of times in order to ensure that they do not fail under repeated use.  All of these models need to be fairly precise and when combined would provide a larger detailed model of how the whole engine may perform under hard repeated use.

 ===Design Changes and Recommendations===
-This motor is very heavy and would be exhausting to push around. One of the biggest things that could be done to improve this engine is to decrease the over all weight and the over all package size. Most of the materials could be lightened by using alluminum or some other alloy and still have the strength needed. Parts such as the gas tank could be redesigned to compact the entire package, other parts can be completely removed. The intake tube between the carbuerator and the engine block can be taken out and the carbuerator can be bolted directly to the block. This would reduce cost of manufacturing. Almost all of the rotating compenets could be reduced in weight this would allow the motor to reach opperating speed faster, rev higher, and increase power by decreasing the rotating mass. The piston head and cylinder can be increased in diameter to increase displacement and increasing power. A switch to a fuel injection system would help improve fuel economy because the amount of fuel and the timing of fuel can be controled. The muffler could be improoved to have more baffels in it to make the engine quieter and more comfortable for the user. Air flow could be improved by porting the heads and using bigger valves, this would increase the power of the motorby making it easier for it to get the air and fuel in and out.
