What is Mean Piston Speed Names Orientation In this activity you will be calculating the mean piston speed for a bunch of different engines that vary in type and size When scaling findingsresults from a small scale to a large scale it is important to identify underlying concepts to do the scaling to In this course the mean piston speed will allow you to make predictionsassumptions necessary when solving problems Learning Outcomes 1 Be able to calculate mean piston speed ms for variety of engine sizes and units 2 Understand how to predict a max RPM making an assumption about mean piston speed Targeted Skills Identifying assumptions 7 examining preconceptionsbiases Generalizing solutions 7 modifying for broader applicability Persuading 7 using information selectively to convince Max MPS Engine Cylinders lquot 39 Bore Stroke RPM mls Cl Engines Cummins ISB 24v 6 59 L 402 in 472 in 3200 Cummins ISX DOHC 6 15 L 54 in 67 in 1900 USS Bowfin16278A 16 145 L 834 in 1012 in 1300 SI Engines Ford 351W stock 8 351 inquot3 40 in 35 in 4500 Cadillac 472 8 472 inquot3 43 in 406 in 3700 Chrysler K car 4 22 L 875 mm 92 mm 4200 HighPerf Engines Honda 8168 Type R 4 16 L 81 mm 774 mm 9000 Ford 351W Race Prep 8 351 inquot3 40 in 35 in 7200 Polaris 600 XC SP 2 600 00 772 mm 64 mm 10000 Honda CBR F4i 4 600 cc 67 mm 425 mm 14500 Honda D16Z6 4 16 L 75 mm 90 mm 7200 1 Calculate the Mean Piston Speed for each of the above engines Report this in units of ms 2 What can we say about Mean Piston Speed relative to the size Swept Volume of an engine 3 What information is most necessary when estimating Mean Piston Speed for an engine when you don t know its Stroke and max RPM 4 Why are the Mean Piston Speeds lower for the CI Engines
