So how about an engine that sings? French technicians have programmed the controller for an Asiatech 10-cylinder, 750-hp Formula 1 engine (based on a Peugeot design), to run through various rpm/note ranges in the correct sequence to play a rousing sequence of musical notes. With five combustions per revolution at a frequency per second of 12/rpm [60/(5 x rpm)], the engine can produce revs for a particular note by multiplying the note's frequency by 12. For example, a 440 Hz A note needs 5,280 rpm and a C needs 3,139 rpm. For a demonstration of "When the Saints Come Marching In," go to http://astro.temple.edu/~kmr/Chauffe2.mp3.
