The description of "the internal combustion engine that powered the first industrial revolution" is some kind of fantasy. As ChatGPT puts it: The “first industrial revolution” was powered mainly by steam engines, not internal combustion engines. Internal combustion engines became important later, during the late 19th century / Second Industrial Revolution. Typical piston internal combustion engines do not have “two complementary pistons” called “intake” and “compression.” Intake, compression, ignition/power, and exhaust are strokes (phases of operation), not pistons.
