Due to liability issues associated with the Hill Climb Event, students will not be permitted to drive the snowmobiles, regardless of qualifications. A10 - Premium gasoline will have an octane rating of 91. The 600cc displacement limit will remain as stated in Rule 4.2.1. All three engines thermodynamically follow the same four phase Otto Cycle, however the mechanical execution of this cycle is completely different for all three. In the CSC2001 rules, four stroke engine displacement is set at 1.6 times the two-stroke engine displacement.
Rotary engines produce three power pulses per crankshaft revolution.
This would translate into a 480 cc limit for rotary engines in the SAE CSC2001 rules. The question was raised and the displacement set after the team proposals had already been submitted. The CSC2001 rotary engine limit was set to 600cc's after taking into consideration these proposals and the implications of this ruling for teams who had selected the rotary engine as their powerplant , as well as the limitations of availability for this class of engine. Displacement is factored into the cost using the 'engine size factor'. Q14 - My question is in regards to the modification of the chassis.
