Abstract

resumo patente de invenção: "dispositivo de preaquecimento para um sistema de injeção de combustível". a presente invenção refere-se um dispositivo de preaquecimento (3) para preaquecer um combustível de um motor de combustão interna que compreende um alojamento (5), que tem uma abertura de entrada (6) para conectar o dispositivo de preaquecimento (3) a uma tira de distribuidor (2) de um sistema de injeção de combustível (1) do motor de combustão interna e uma abertura de saída (7) para conectar um injetor de combustível (4) do sistema de injeção de combustível (1) no dispositivo de preaquecimento (3), uma câmara de preaquecimento (10) que pode ser atravessada pelo combustível e a qual está envolvida pelo alojamento (5) e fluidamente conectada na abertura de entrada (6) e na abertura de saída (7), e ainda compreendendo pelo menos um elemento de aquecimento elétrico (12) para aquecer o combustível dentro da câmara de preaquecimento (10). de modo a conseguir uma estrutura econômica, o respectivo elemento de aquecimento (12) compreende dois lados externos opostos (13, 14) sobre os quais está disposto em cada caso pelo menos um corpo de transferência de calor metálico (15, 16) o qual entra em contato com o combustível dentro câmara de preaquecimento (10).patent summary: "preheating device for a fuel injection system". The present invention relates to a preheating device (3) for preheating a fuel from an internal combustion engine comprising a housing (5) having an inlet opening (6) for connecting the preheating device (3) to a distributor strip (2) of an internal combustion engine fuel injection system (1) and an outlet port (7) for connecting a fuel injection system fuel injector (4) (1) to the device preheating chamber (3), a fuel-passable preheating chamber (10) which is surrounded by the housing (5) and fluidly connected to the inlet port (6) and outlet port (7), and further comprising at least one electric heating element (12) for heating the fuel within the preheating chamber (10). In order to achieve an economical structure, the respective heating element (12) comprises two opposite external sides (13, 14) on which at least one metal heat transfer body (15, 16) is arranged in which case. contacts the fuel inside the preheat chamber (10).
