week 7

Today after class our group members all went to library to discuss the details of our technology project.our topic is is high performance cars used straight pipe instead of the catalytic convertor, but there is a problem, the problem is straight pipe can not resist the engine air flow especially when the drivers release the accelerator pedal so the torque is reduced. we want to install a butterfly in the exhaust pipe and use the accelerator pedal to control the butterfly,it sounds no hard, but if we want to do this project it very difficult to do it that our supervisor gerry said. after the group conversation we were distributed some jobs to do, we have to find some pipe ,the pipe has to be the exact size as the engine exhaust pipe we choosed, i looking for some pipe on line at home, when i was looking for the pipe i was worried about how can we install the butterfly in the pipe and how can we control the butterfly? i was very confused .
