Project - Crankcase breather characterisation and simulation
“My task was to characterise and simulate the Indian’s Bunn Breather System to determine its suitability for use in the Indian crankcase breather. The Bunn Breather allows the motorcycle to allow more air flow through the crankcase, purging Blow-By-Gas and lowering the mean crankcase pressure, thus reducing oil leaks, power losses, increased fuel consumption, corrosion and damage”.
“I had to characterise the Bunn Breather valve dynamic behaviour for both large and small valves up to 6000rpm ≈ 100Hz and also produce a computational fluid dynamics model of the valve behaviour. Additionally, I had to produce a dynamic model to aid understanding and to use as a tool to optimise engine crankcase ventilation performance.”
Challenges
“The idea of testing any valve at such high frequency (up to 6000rpm ≈ 100Hz) is challenging so designing the testing rig used to characterise the current Bunn Breather valve was demanding. After some research it was clear that using a lot of existing pneumatic valves such as solenoid valves didn’t have the response time needed so I then designed a special dynamic test rig using purely mechanical approach.”
Highlights
“I love engines of any kind and really wanted to work on this project. Seeing the rig I had designed working and doing its job during dynamic testing. Also seeing the face of the client (Rex Bunn) when he saw the work we had done and how happy he was a real highlight. Answering countless questions from him afterwards was also very rewarding.”
Lessons learned
“I learnt so much, not only about myself and my work habits but also in doing a project you learn project management in a direct manner. I learned to develop models from fundamental laws of mechanics which was balanced with the wonderful chance to spend time in the workshop, making parts for the rig as well as testing of the system. Team work was a large part of my project with Sam Jack being my project partner. Finally I learned to write a full project report and the sleepless nights that come with it.”
