Today we arrived in London! The work started right away with great efficiency. Things left to do before the safety inspection and competition is mounting the new door, finish the foiling of the car body and fixing the clutch ECU that is non-functional at the moment. This will most probably be finished tomorrow, since we now know that the error in the clutch ECU was a pin that was grounded when it shouldn’t. We also need to do a few more tests on the internal combustion engine and it’s ECU.
A lot has happened since the last update. Most notably we have a new internal combustion engine that we have modified. A test rig has been built for the engine where we will identify important parameters for our model of the car.
Speaking of models, the plant model of the car has been improved and can now be simulated with the track in London. Aside from simulations we also went for a test drive IRL outside the Integrated Transport Research Lab here at KTH to verify the previous system and let our driver get used to the car.
Furthermore we have streamlined the auxiliary power system to make it more robust and the design for the new clutch is underway.
More updates to follow!
The work with KTH’s entry for Shell Eco Marathon 2016 is in full swing! We are a team of 16 excited students from Machine Design, Internal Combustion Engine, Lightweight Construction and Mechatronics.
The competition this year will be held in London between the 27th of June and the 3rd of July where we will compete in the class Urban Concept.
The focus this year will be to develop an optimized drive cycle designed for the competition track. We will also improve upon current inefficiencies in the power-train.
To be continued…
ElBa ran its first attempt and the race was valid! The car made it through 10 laps with a total distance of 16117 meters under 36 minutes, which means that the car had an average speed of 27 km/h. ElBa came fourth with a result of 96 km/L . We are going to compete again now after some adjustments, for example the small motor will be used this time instead of the big motor in lower velocities and hopefully this will reduce the fuel consumption and get us to the third place.
