  1. Engine TeamStatus Update February 17, 2009

  2. Agenda • Engine • ECU • Cooling • Electrical • Engine Dyno

  3. Current engine • Honda f4i • 599 cc • Compression ratio : 12:1 • Production 2001-2006 • Power in bike:109hp (crank )46 ft lb (crank)@12500 rpm and 10000 rpm

  4. Other options • Suzuki GSX-R600 (599cc)compression ratio 12.5:1 (04-07),12.8:1 (08-10)power (crank): 125 hp @ 13,500rpm • Honda CBR 600RR (599cc)compression ratio 12:1 (03-06), 12.2:1 (07-10) • Kawasaki Ninja ZX-6R (599cc)compression ratio 13.3:1 (03-10), 13.9:1 (08)peak power @ 12,250 (05), 12,700 (07), 14100 (09) • Yamaha YZF-6R (599cc or 600cc before 06)compression ratio 13.1:1 (10), 12.4:1 (01-05)peak power @ 14,500 (06-10)

  5. Engine Control Unit • What is an ECU: • Electronic device charged with determining the exact amount of fuel, ignition timing, etc. required to smoothly operate an ICE. • Functionalities: • Fuel Injection • Determining the appropriate A/F ratio based on throttle position, RPM, MAP • Ignition Timing • Adjusting ignition timing for ideal power delivery/fuel efficiency/engine smoothness • I/O:

  6. Engine Control Unit • Different ECUs, Different Functionalities: • What is the best ECU for our team? • What can different ECU’s do/What are the benefits/downsides of popular ECU’s used by other FSAE teams? • Research currently ongoing • Currently considering (for academic purposes): • Performance Electronics-ECU1 • Megasquirt II, V3.0 Board • MoTeC M4

  7. Tuning Theory • Basic Tuning Theory Knowledge from here: • http://www.megamanual.com/begintuning.htm Solid introduction to how ICE’s work, stoichiometric calculations/AFR, how to generate good fuel maps, etc.

  8. Past + Present: • One radiator mounted under side pod • Custom thermostat housing • F4i stock water pump • Single pass radiator Cooling Future Concepts: Different positions Oil cooling Double pass radiator All aluminum tubing

  9. Engine Electrical • Goals: • Have finished (real) electrical diagram by end of week • Rewire a previous racecar (CMR79) by spring break • While rewiring CMR79, develop and document the process of rewiring, and compile a list of components as a full electrical inventory of the racecar
