Naitoh, K., Shirai, T., Tanaka, M., Nojima, Y. et al., "Fugine as Single-Point Compression Engine based on Supermulti-Jets Colliding with Pulse: Combustion Test of Second Prototype Engine with Strongly-Asymmetric Double-Piston System," SAE Technical Paper 2015-01-1964, 2015, doi:10.4271/2015-01-1964.
We proposed a new compressive combustion principle for an inexpensive and relatively quiet engine reactor that has the potential to achieve incredible thermal efficiency. The high efficiency can be achieved with colliding supermulti-jets that create complete air insulation to encase burned gas around the chamber center.We developed a small prototype engine system for gasoline, which has a strongly-asymmetric double piston and the supermulti-jets colliding with pulse. In this report, we will show combustion experimental results at startup and at steady state operation. We obtained exhaust temperature over 100 degree Celsius and pressure data, which imply auto-ignition occurrence of gasoline.
