We start this week pretty much from where we left off in the previous week. STILL NO IDEA FOR A PROJECT! This is worrying as we have to present our issue and solution for a technological project in week four. How are we going to do that if we do not yet have a project idea.
After doing a bit of thinking I realized that Ive always wanted to try and incorporate an exhaust brake into petrol engines. My idea is inspired by the exhaust brakes used within trucks.These brakes help the trucks maintain control under deceleration and also assist in slowing down and stopping the truck. I discussed my idea with my partner Richard and we both felt that it was an good idea.
However after doing some research my partner Richard told me that my idea of an exhaust brake within petrol engines would not be viable. This was discouraging news. I decided to ask Anura who is my EMS lecturer about why it would not work. He told me well this is simple. Petrol engines are air controlled; therefore under overrun conditions the exhaust gasses would be very low to create a backwards pressure. Diesel engines on the other hand are fuel controlled.
Me and Richard took that information and decided to create a retro fit exhaust brake for small diesel engines such as SUVs and pickup trucks. Doing further research we found that such kits are already available but they are vacuum controlled. To make ours unique, we decided to make our kit electrically controlled.
