I think what you meant to say was: "Carburetor vs. *electronic* fuel injection" All Diesel (compression-ignition) engines use fuel injection, and many spark-ignition (Otto or Wankel) engines use fuel injection of one kind or another. The first patent for a fuel injection system was issued to George Bailey Brayton in 1872, so it's not exacly new technology. The first fuel injected engines for passenger car use became available in late 1930s and early 1940s. Early mechanical injection systems (except for air-blast injection) typically used injection valves with needle-like nozzles in combination with one or multiple relatively sophisticated helix-controlled injection pumps that both metered fuel and created injection pressure. They were well-suited for intermittent multi-point injection systems as well as all sorts of conventional direct injection and chamber injection systems. https://en.wikipedia.org/wiki/Daimler-Benz_DB_601 https://en.wikipedia.org/wiki/BMW_801 https://en.wikipedia.org/wiki/Rolls-Royce_Merlin I would daresay that any one of these designs would survive an EMP and keep turning out enormous horsepower with no trouble at all.
