  • Patent number: 11959426
    Abstract: A conventional gasoline engine is retrofitted and calibrated to operate as a bi-fuel engine using Hydrogen as the second fuel. When operated with Hydrogen, which typically leads to a reduction of engine output power, the engine is preferably operated in a charged mode and in a lean mode with the engine throttle kept in a wide-open position during charged and lean mode operation resulting in a more efficient engine with a reduction of engine output power loss.
    Type: Grant
    Filed: September 1, 2022
    Date of Patent: April 16, 2024
    Assignee: H2 IP INVESTMENTS LTD.

  • Patent number: 11149668
    Abstract: A conventional gasoline engine is retrofitted to operate as a bi-fuel engine using Hydrogen gas as a primary fuel and gasoline as a secondary fuel at various acceptable air fuel ratios while avoiding forbidden air fuel ratios. The engine is preferably operated to burn Hydrogen fuel in a charged mode and lean mode at certain acceptable air fuel ratios where relatively little NOx emissions occur. When additional power or acceleration is requested, processor controlled fuel injectors are operated to inject relatively small amounts of gasoline into the engine resulting in a fuel mixture that prevents increases in NOx emissions as the processor operates at a stoichiometric air fuel ratio where a catalytic converter is best able to reduce harmful emissions. The injection of the liquid gasoline fuel to the gaseous Hydrogen fuel reduces the temperature of the fuels significantly and reduces or eliminates backfiring tendency of the engine.

The engine is preferably operated to burn Hydrogen fuel in a charged mode and in a lean mode at certain acceptable air fuel ratios where relatively very little NOx emissions occur. When additional power or acceleration is requested, processor controlled fuel injectors are operated to inject relatively small amounts of gasoline into the engine resulting in a fuel mixture that prevents increases in NOx emissions as the processor controls the engine to operate at a stoichiometric air fuel ratio where a catalytic converter is best able to reduce harmful emissions into the environment. The injection of the secondary liquid gasoline fuel to the gaseous Hydrogen fuel the temperature of the fuels significantly reduces or eliminates backfiring tendency of the engine.
