UNIVERSITY AT BUFFALO SI AUSTIN KEPPLER / AUSTIN OCWIEJA
LAST YEARS RESULTS Bearcat 3000 Chassis 700 Ctec4 2 cylinder four stroke engine Exhaust manifold failure during endurance event
2019 CLEAN SNOWMOBILE STRATEGY Build a snowmobile that can be built upon in future years Sustain performance characteristics that would make the snowmobile marketable Focus on reducing noise output of both the engine and chassis
CHASSIS 2017 ZR 3000 Lightweight Trail suited Same basic platform as previous year
ENGINE Arctic Cat Ctec4 700cc 2 Cylinder Four Stroke
ENGINE MANAGEMENT Motec M130 Closed Loop Fuel Tuning Flex Fuel Compatable Tuned to run at stoichiometric combustion
TURBOCHARGER BorgWarner KP 35 Pboost+Patm Patm Pressure Ratio = 1 2Engine Displacement Max RPM V.E. D.R. 1728 CFM = Utilize these parameters to locate efficiency on compressor map
EXHAUST Factory Exhaust Manifold Precision Turbo Wastegate Honda Muffler 3 Way Magnaflow Catalytic Converter Custom Built Resonator
RESONATOR ? ? ? = 2? ? ? Identified droning frequency around ~59 - 60 Hz
CHASSIS NOISE REDUCTION Tested several different materials Foam Lizard Skin Spray Paint Enclosed test fixture
TEST RESULTS Average dB 104 99 94 89 84 100 200 300 400 500 600 700 Frequency (Hz) Black Foam Grey Foam Lizard Paint Bare Metal
CONCLUSION Successfully created a low noise emitting snowmobile Unfortunately ran into small undetected problems that led to the failure of the snowmobile
