Compression Ignition: Otto, Diesel and Thermal Efficiency
Three milestones in which an engine was designed from a thermodynamic argument rather than developed from an existing machine, and immediately outperformed everything else.

Three milestones in which an engine was designed from a thermodynamic argument rather than developed from an existing machine, and immediately outperformed everything else.
Three milestones united by fluid mechanics: a machine that generates lift to fly, a rig that generates lift to outrun the wind, and a cycle that moves heat against its gradient.
Five milestones across eighty years that turn a laboratory observation about atmospheric pressure into a general source of industrial power.
Two technologies with a straightforward efficiency argument that says run hotter, and one shared constraint: both are limited by what the hot parts are made of, not by thermodyn…
Six milestones in which electricity acquired its first mass market, and in which the decisive engineering turned out to be system design rather than lamp design.
Four milestones in which marine propulsion moved from consuming most of the ship to leaving room for the cargo that paid for it.
Spark ignition against compression ignition, why compression ratio governs efficiency, and how diesel-electric traction solved the transmission problem by deleting it.
Four milestones in which the compact high-pressure engine and the iron hull between them end the age in which transport meant wind, water and muscle.
Four milestones showing a field that acquired chemistry rather than physics, and in which the decisive advance came from a part-time experimenter working in a cellar.
Three milestones, and an unusually clean case of a first design getting the architecture right, plus a patent case worth knowing.
