摘要

Energy in, mechanical power out-that sums up an engine. It's genius that keeps the world moving at every level. Fitting, then, that genius is built right into the Latin root word, ingenium, from which engine derives. Ingenious or not, things can and do go wrong. When an engine quits, it's natural to want to know why, even if the engine is headed to a repair shop. And in most cases, that's where it should be headed if there's a problem.
