  "country": "US",
  "title": "How Rudolf Diesel's Engine Works",
  "original_title": "Internal-combustion engine",
  "summary": "Rudolf Diesel's 1898 patent describes a highly efficient engine that ignites fuel using the heat generated by compressing air rather than using a spark plug.",
  "what_it_does": "The engine operates by drawing in air and compressing it to such a high pressure that the temperature rises significantly. Once the air is hot enough, fuel is injected directly into the cylinder. The fuel ignites spontaneously upon contact with the superheated air, eliminating the need for an external ignition source like a spark plug.",
  "what_it_does_not_cover": [
    "Does not cover engines that use spark plugs for ignition.",
    "Does not cover engines that mix fuel and air before compression.",
    "Does not cover external combustion engines like steam engines."
