abstract a method for fuelling an internal combustion engine, and a fuel system (10) for delivering a variety of fuel types to the engine, with selected fuel types typically being chosen according to their availability. the fuel system (10) can be configured to accommodate liquid fuels such as gasoline, ethanol or a blend thereof, and gaseous fuels such as cng, lng or lpg. the engine is configured to operate on any of the designated liquid fuels, and can switch between the liquid and gaseous fuels. the fuel system (10) includes a respective common delivery arrangement (11) for selectively delivering fuel into the combustion chamber of each cylinder of the engine. the common delivery arrangement (11) comprises at a fluid delivery device (12) and a liquid metering device (31) configured for operation in concert. the fluid delivery device (12) comprises a fluid delivery injector. fuel is delivered to each combustion chamber is through the same fluid delivery device; that is, the same fluid delivery device (12) is used, regardless of the fuel type. more particularly, the fluid delivery device (12) can be used for delivery of gaseous fuel only, delivery of liquid fuel only (by way of an air assist delivery process), or delivery of a fuel mixture comprising the gaseous fuel and the liquid fuel according to the fuelling requirements of the engine at any time. _________________________________________________________________________________ tradução do resumo resumo patente de invenção: "sistema de dispensa de múltiplos combustíveis". método para abastecer com combustível um motor de combustão interna, e um sistema de combustível para dispensar uma variedade de tipos de combustível no motor, configurado para acomodar combustíveis líquidos, tal como gasolina, etanol ou uma mistura dos mesmos, e combustíveis gasosos, tal como cng, lng ou lpg. o motor é configurado para operar em qualquer dos combustíveis líquidos designados, e pode comutar entre combustíveis líquido e gasoso. o sistema de combustível inclui uma disposição de dispensa comum para seletivamente dispensar combustível na câmara de combustão de cada cilindro do motor, compreendendo um injetor de dispensa de fluido e um dispositivo de medição de líquido configurados para operação em conjunto. o mesmo injetor de dispensa de fluido comum é usado para a dispensa de combustível gasoso apenas, a dispensa de combustível líquido apenas (por meio de um processo de dispensa assistido por ar), ou a dispensa de uma mistura de combustíveis compreendendo o combustível gasoso ou o combustível líquido. A method for fuelling an internal combustion engine, and a fuel system (10) for delivering a variety of fuel types to the engine, with selected fuel types typically being chosen according to theft availability. The fuel system (10) can be configured to accommodate liquid fuels such as gasoline, ethanol or a blend thereof, and gaseous fuels such as CNG, LNG or LPG. The engine is configured to operate on any of the designated liquid fuels, and can switch between the liquid and gaseous fuels. The fuel system (10) includes a respective common delivery arrangement (11) for selectively delivering fuel into the combustion chamber of each cylinder of the engine. The common delivery arrangement (11) comprises at a fluid delivery device (12) and a liquid metering device (31) configured for operation in concert. The fluid delivery device (12) comprises a fluid delivery injector. Fuel is delivered to each combustion chamber is through the same fluid delivery device; that is, the same fluid delivery device (12) is used, regardless of the fuel type. More particularly, the fluid delivery device (12) can be used for delivery of gaseous fuel only, delivery of liquid fuel only (by way of an air assist delivery process), or delivery of a fuel mixture comprising the gaseous fuel and the liquid fuel according to the fuelling requirements of the engine at any time.
