Have you ever wanted a running engine with repeatable mechanical faults that all of your students could diagnose? Would you like an engine system that has internal mechanical faults not requiring you to reinsert and repair them after each student use? The EM-141S-TY01 does exactly that. It was designed for the purposes of teaching students mechanical engine component failure diagnosis and is a real time-saver allowing instructors to instantly provide a “turn-key” engine mechanical fault diagnosis package.
