Basics

  • This page is focused on pre-dev research on the Open Source Piston Engine
  • The Youtube Channel "Engineering Explained" has great information, and explanations on all sorts of engine related stuff, especially developing technologies

Emissions Contol

Piston/Combustion Chamber Layouts

  • Electronic valves - eliminates need for camshaft and rockers, allowing higher simplicity, and 30% efficiency gain.
  • DIY campless - [2]
  • Camless engines are not yet available, outside of some large diesels. [3] -from 2016, is this still relevant, looking into this right now
  • Free piston engine - drives a working fluid directly, without crankshaft
  • Stelzer engine - 2 opposing combustion chambers with middle pumping chamber. [4]. Pertinent popular references -

[5] and [6]

  • Free piston engine linear generator (FPEG) - [7]
  • Hydrogen-powered linear generator is reportedly as efficient as fuel cells - [8]. Discusses linear generator configuration fired on both sides. Also discusses compression ignition of non-diesel fuel - via homogeneous (premixed) charge - (HCCI) . Peter Van Blarigan, Sandia Labs Sme.png


  • Homogeneous charge compression ignition - [9]
