Engine on Demand™ (EoD™)

Our Engine on Demand™ (EoD™) technology, or Cluster Engine™, can be simply described as follows: A standard combustion engine is intersected between two cylinders into single engine sections that are reconnected at the crankshafts or/and the camshafts by clut- ches, so that one or more engine sections, or in its purest version even each single-cylinder engine can be totally switched off and on as needed. Alternatively, several engines are taken directly for the construction. In comparison to other solutions that only switch off and on the fuel and ignition systems of one or more cylinders our technology is 50 to 90% more efficient, because no mass must be moved without any use and no friction is produced by a switched off cylinder at all.

Most Efficient Combustion Engine
The technology can be combinded with every kind of
forced induct- ion and energy regeneration system. In this way we could make the before most efficient engine worldwide, our high performant Looped Combined Combustion Engine, even more efficient by around 12 to 15%. The worldwide most efficient reciprocating engine looks now as follows:

  • Combined Combustion Engine™ (CCE™)
  • Engine on Demand™ construction (includes standard start-stop system),
  • Compound Forced Induction Architecture™ in a Tricharger™ configuration with Twincharger Bank™ composed out of a
    • Supercharger Bank™ for low number of revolutions and
    • Turbo Bank™ for high number of revolutions,
    or with a and
  • energy regeneration systems including so that we have in the end a Supercharged Looped Combined Combustion Cluster Engine™ (SLC³E) with Turbo Bank and BERS.

    Intelligent Engine Management
    With a more complex engine that features a
    forced induction or/and an energy regeneration system the engine management has now a much larger set of options for selection. For example, in an intellig- ent way the engine management system now controls not only the amount of fuel that has to be injected as well as the right timing for this and the ignition, or the start and stop, but also decides if it is more efficient to switch on or off a cylinder, use an energy recovery system, give more or less pressure by controlling the forced induct- ion components appropriately, or even make a mixed adjustment in- stead. In this way an engine can deliver its maximal performance and highest efficiency.
