P10221: Baja 1 (Baja Driveline Test Development)/public/
Table of Contents
Attendees: Brian Helm, Matt Tranter, Jeffrey Ryan,Chukwuchebem Orakwue
- Start time: 6:15 PM
- End time: 7:45 PM
- Engine must be bolted to the Dyno easily.
- In the project outline, we need to stress what we are trying to gain. For example improve specs, get baseline numbers, and fulfill objectives.
- Need to figure out what we will do this quarter for MSD 1 and also what we will do for MSD 2.
- Use excel spreadsheet with tabs for short term deliverables and long term deliverables. Use word to create weekly summaries with what you have done, issues, and what you want to do.
- Design questions: 3 stands or 1 for the design? Quick disconnect is needed. Type of transducers going to be used? Engine mount placement? Mount parts? Vibration concern? Different sprocket for dyno or engine? Speed of implementation?
- Need to get a good CVT and engine from Baja. Could rebuild gaskets to get right cylinder pressure.
- 1 team member needs to meet with Baja in their weekly meetings to make it known we're serious about helping them. Also at the 5th and 9th week reviews have the Baja board there.
- Create pitch to Baja board about the project. (Power train test team for the season)
- Need to validate small dyno sensor by the end of MSD 1.
- Engine specs needed: Crankshaft angle (encoder) cylinder pressure, oil temp, head temp, inlet air temp, air flow rate, exhaust temp, A/F ratio, O-2 sensor measurement.
- Dyno operation and info: Dyno has rpm sweet spot. Depends on the ratio of the sprocket. (has already a 528 chain) Need airflow to cool the engine in room. Might have an exhaust draw problem with the rooms exhaust system. Holes in dyno stand every 4 inches apart.
- Safety procedure needed.
- Dyno time will be an issue with other groups also using the dyno.
- Dyno has fuel injection already set up. We need gravity fed injection.
- We have 8 thermocouples at our disposal.
- There could be a 4 week lead time for getting the right sprocket.
- Could make a signal board when we do the testing.
- If we knew what the CVT load output is in the real world, we can change the springs to get different results.
- We need a throttle encoder so we can have the exact amount of throttle at any given time.
- We might need to assume certain specs about the engine and run with it. We can make sure it is easily changed down the road.
- Need to find out how much fuel storage.
- Need wide range O-2 sensor.
- There's a 2 % loss with the chain drive between dyno and engine.
- Risk management: Noise from engine might interfere with sensors.
- Need to get space in senior design room. (table to keep parts at)
- Test procedure and high level timeline need to be done ASAP.
- 9-16-09 6-8 PM.
DeMinco Action Items:
- Find out 0 rpm torque rating for dyno.
- O-2 sensor parameters.
- Ignition system encoder.
