Engine Team Status Update

This update outlines our team's progress and ongoing research in engine technologies as of February 17, 2009. We focus on the Honda F4i engine specifications, comparing it with competitors like Suzuki GSX-R600 and Kawasaki ZX-6R. Key topics include understanding Engine Control Units (ECUs), their functionalities, and the benefits of various ECU options like Performance Electronics and Megasquirt. We also discuss current cooling system designs and our goals for completing the electrical diagrams and rewiring processes for our racecar by spring break.

  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
