Ingо wаs plаnning his presentаtiоn tо a group of sixth graders about the internal combustion engine. “I’ll start in the late 1790s,” he began, “and outline successes and failures of that era, leading into the mid-1800s. Naturally I’ll discuss the different fuels that can be used, and the nuances of a two-stroke, four-stroke, and six-stroke process, noting applications to the Wankel rotary approach and the Otto cycle. Hmm . . . I’ll need time for the pros and cons of the Scuderi engine, and I should probably touch on the early Mazda campaigns and why they seemed revolutionary at the time.
