用于将水溶液注射到内燃机的燃烧室中的车辆系统和方法
摘要：
本发明涉及一种构造为将水溶液注射到位于内燃机的燃烧室(14)上游的进气线(12)中或该内燃机的所述燃烧室(14)中的车辆系统(80)，所述车辆系统(80)包括以下车辆系统组件：用于存储水溶液的储箱(16)；泵(18)；位于内燃机的燃烧室(14)上游的进气线(12)；一个或更多个构造为将水溶液注射到所述进气线(12)中、所述燃烧室(14)中或两者中的注射器(20)；构造为给所述注射器(20)供给由所述泵(18)泵送的水溶液的供给线(22)。在所述车辆系统中，至少一个所述车辆系统组件(16、18、12、20、22)或所述储箱(16)的构件(24)的至少一部分由聚合物材料制成。所述聚合物材料：-包括有效量的至少一种抗菌剂，或-在其表面上具有包含至少一种抗菌剂的表面覆层，该表面覆层包括0.001wt％到0.25wt％的该至少一种抗菌剂。
摘要（英）：

The present invention relates to a vehicle system (80) configured for injecting an aqueous solution in an air intake line (12) upstream of a combustion chamber (14) of an internal combustion engine, or in the combustion chamber (14) of the internal combustion engine, said vehicle system (80) comprising the following constituents: a tank (16) to store an aqueous solution; a pump (18); an air intakeline (12) upstream of a combustion chamber (14) of an internal combustion engine; one or more injectors (20) configured for injecting aqueous solution in the air intake line (12), in the combustion chamber (14) or both; a feed line (22) configured for feeding said injector (20) with aqueous solution pumped by the pump (18). In the vehicle system, at least a portion of at least one of the vehiclesystem constituents (16, 18, 12, 20, 22) or of a tank (16) component (24) is made of a polymer material. The polymer material comprises an effective amount of at least one antimicrobial agent, or hason its surface a surface coating containing at least one antimicrobial agent, the surface coating comprising between 0.001 % by weight and 0.25 % by weight of the at least one antimicrobial agent.
