Week Eight

This week the lab group made a trip to Jason Gallaghers house to begin testing. On the way to the testing site, gasoline was acquired to perform the control test with the engine running on its intended fuel. The lab group got to work setting up the engine and fuel tank. It was powered via the electric start using a battery powered jumper box. Once the lab group got the electrical system set up, it came time to adjust the carburetor to allow for the proper gas to air ratio so it would run properly. This took a while, as initially gasoline was just injected into the carburetor through air intake to get it started This, however, made it stall out after running for about 30 seconds. The aim was to have it run for at least a minute in order to ensure that it attained its maximum output and the data could be properly collected. After making the appropriate adjustments, the engine was finally able to run for over 2 minutes. The lab group then proceeded to attach the temperature probe to the exhaust outlet.This would keep measuring the exhaust temperature until it reached a stable maximum value which could be recorded. Lacking access to pure alcohol, it became necessary for the lab group to seek alternative sources of the alcohol. Following the  initial experiment, ethanol was acquired in the form of 190 proof (95% alcohol) Everclear. The lab group plans on finishing testing on Sunday of week 9.

Week Seven

This week the lab group continued gathering supplies and refined the details on the experiment even more. After realizing it would be extremely inefficient to attain hydrogen the project prameters had to be modified. The lab group, with assistance from the group adviser Som Tyagi, decided that the objective of the project would be to measure the efficiency difference between gasoline and gasoline combined with varying amounts of ethanol. To do this the lab group decided to test the gasoline mixture attained at a local gas station to that of various ethanol gasoline blends. This week the lab group also attained various materials for the experiment. These materials were a gas tank as well as the oil necessary for the lubrication of the engine. Som Tyagi also provided a temperature probe for the experiment, and the aperture design for fuel injection was finalized.

Week Six

After referencing dozens of Chinese electrical diagrams, this week the lab group prepared the engine for use by wiring up the engine so that the kick start would produce a charge and create a spark via the spark plug. The lab group also wrote up the draft final report for the experiment. The search for a site to conduct the experiment safely and without disturbing other continues. However, due to the fact that the experiment releases harmful exhaust, the lab group was barred from utilizing any of the Drexel campus labs. Therefore the lab group decided that it would be most reasonable to do the lab at an off campus location at Jason Gallagher's house.
