Toroidal vortex induction diffuser

Abstract

In certain embodiments, a PFI diffuser induction device may use toroidal vortex flow to thoroughly mix H2 and air in the intake runner and port of a H2 engine. When H2 enters a stream of air flow in the form of a toroidal vortex, it may tend to swallow the air into the vortex where a low-pressure region may be formed due to the swirling velocity of the vortex, which may be more effective that the typical mixing via conventional injection methods. Engine test measurements show remarkable improvements in engine combustion stability as well as engine efficiency and power output using a counterflow Toroidal Vortex Induction Diffuser to achieve high levels of fuel mixture homogeneity in combustion engines using hard-to-mix fuels like H2, CH3OH, C2H5OH and other gaseous and liquid fuels.
