With our third week into the technology project our group had still not come up with an idea for the technology project. This is becoming concerning as we have to make our first presentation for week four of the technology project. It seems as though everyone else has come up with an idea except for us and I feel a bit left behind.
However my team mate Jal came up with a good idea to create a retro fit kit exhaust brake for petrol engines. The idea drew inspiration from the exhaust flaps used in diesel trucks which closes off the exhaust pipe and essentially suffocates the engine. This removes the combustion process and turns the engine into an air compressor which aids in deceleration or engine braking.
After a bit of research I did however discover that this idea would not work on petrol engines because of the throttle body. The butterfly valve closes of a large percentage of air to the engine during idle and engine braking. This translates to small exhaust flow, and there would not be enough exhaust gases to help the engine slow down.
With a bit more research I did discover that there is already a retro fit kit exhaust brake for diesel engines in SUV's and utes. These kits are vacuum controlled and with a bit of modification to the original idea we decide to create an electronically controlled kit for diesel engines in utes and SUV's when they are towing heavy loads to help improve engine braking.
