The Olshammar Engine

Unlock the future of engine performance. At Olshammar Nebula AB, our patented technology boosts power and cuts fuel use—proven by cutting-edge simulations. Our tech delivers results: 10% less fuel and 16% more power for petrol engines at 3.5 bar boost. Diesel and two-stroke engines see even bigger gains—up to 95% more power. Discover the results of our GT-Power computer simulations and contact us to cooperate.

Layout in GT-Power

This patent improves the efficiency of engines with high turbo boost.

2023, 31 October – New computer simulations in GT-power has been completed by FEV Sverige AB and the results are very good.

  • a fourstroke petrol (SI) engine show 10.1% lower Brake Specific Fuel Consumption (BSFC) and 16.4% more Brake Power (BP) @ 3.5 bar absolute boost.
  • a fourstroke diesel (CI) engine show 8.2% lower Brake Specific Fuel Consumption (BSFC) and 19.2% more Brake Power (BP) @ 5.5 bar absolute boost.
  • a twostroke diesel (CI) engine show 24.8% lower Brake Specific Fuel Consumption (BSFC) and 95.8% more Brake Power (BP) @ 5.5 bar absolute boost.

You can use the GT Power files to verify the results for each engine model. You can also create your own models to test other fuels. The Artifical Intelligence model GROK predicts that the efficiency gains will be good for Hydrogen, Amonia and Jet-A/Kerosene, and very good for LNG (Liquid Natural Gas) with these predicted gains.

  • Four-Stroke SI LNG: 12-15% BSFC reduction, 20-25% power increase (assuming 4-5 bar boost).
  • Four-Stroke Dual-Fuel: 10-13% BSFC reduction, 25-30% power increase (5.5 bar boost).
  • Two-Stroke LNG (Gas or DF): 25-30% BSFC reduction, 100-120% power increase (5.5 bar boost).

Earlier 2021 computer simulation showed 7% lower Brake Specific Fuel Consumption (BSFC) @ 3.5 bar absolute boost. Summary of these results are presented in video 5 and a report that can be downloaded from The Royal Institute of Technology (KTH) with link to report MasterThesisReport_MF225X_2021
