A vaporized fuel introduction apparatus introduces vaporized fuel to an intake system that includes a compressor housing that houses a compressor impeller and an intake duct that is coupled to an upstream side of the compressor housing. The vaporized fuel introduction apparatus includes a circulation path, a vaporized fuel introduction path, and an ejector mechanism. The circulation path is made up of a housing-side flow path provided as a single body with the compressor housing and a duct-side flow path provided as a single body with the intake duct. The circulation path circulates compressed air flowing in a portion of the compressor housing which is downstream of the compressor impeller to the intake duct. The vaporized fuel introduction path is coupled to the circulation path and guides the vaporized fuel. The ejector mechanism is provided in the circulation path.

The invention discloses a high efficiency combustion control system and a method thereof. A high-efficiency combustion control system includes a gasification unit, a gas remixing zone coupled to the gasification unit, a combustion unit coupled to the gas remixing zone; a first gas detecting unit disposed in the gasification unit; a second gas detecting unit disposed in the remixing gas region; and an air supply unit coupled to the gas remixing zone. The first gas detecting unit and the second gas detecting unit detect the concentration of a specific gas of the first gaseous fuel or the second gaseous fuel respectively. And air is supplied to the liquid fuel or the first gaseous fuel according to the gas concentration, so that the gasification rate is changed, and the calorific value is changed accordingly to obtain the optimal calorific value and the optimal combustion efficiency.

Described herein are catalytic heating systems, comprising catalytic reactors and dual-mode fuel evaporators, and methods of operating such systems. A dual-mode fuel evaporator is thermally coupled to a catalytic reactor and comprises an electric heater used for preheating the evaporator to at least a fuel-flow threshold temperature. Upon reaching this threshold, the liquid fuel, such as ethanol or methanol, is flown into the evaporator and evaporates therein, forming vaporized fuel. The vaporized fuel is mixed with oxidant, and the mixture is flown into the catalytic reactor where the vaporized fuel undergoes catalytic exothermic oxidation. At least some heat, generated in the catalytic reactor, is transferred to the evaporator and used for the evaporation of additional fuel. When the evaporator reaches or exceeds its operating threshold, the electric heater can be turned off and all heat is supplied to the evaporator from the catalytic reactor.

A method for forming substantially consistently-sized and substantially controllably-timed droplets is disclosed. An opening is provided through which a protrusion passes. The protrusion ends at a tip below the opening. A process liquid is provided to the opening at a controlled flow rate. The process liquid passes through the opening and flows along the protrusion, forming a droplet of the process liquid on the tip that reaches a substantially consistent droplet size and falls. The process liquid continues to pass through the opening at an even time interval based on the flow rate. In this manner, substantially consistently-sized and substantially controllably-timed droplets are formed.
