System and method for injecting an aqueous solution on a vehicle

Abstract

The invention relates to a vehicle system comprising: a tank (500) for storing an aqueous solution (A); and a UV light purification module (700) arranged to purify the aqueous solution stored in said tank (500) ). The UV light purification module is arranged in the wall of the tank. The UV light purification module comprises: a light source compartment (720) accessible from an external area (E) outside the tank; and The light transmitting element (760) in the liquid space (L) in fluid communication with the aqueous solution in . The light source compartment comprises a light source (730) for emitting UV light through the light transmitting element into the liquid space.

Description

technical field [0001] The present invention relates to a vehicle system for storing an aqueous solution, preferably demineralized water, on board a vehicle, and in particular to a vehicle system for injecting an aqueous solution into an intake pipe upstream of a combustion chamber or directly into the combustion chamber. Background technique [0002] It is known to inject water into the intake pipe upstream of the combustion chamber or directly into the combustion chamber when the vehicle engine load is high. By injecting water into the air stream, the air is cooled, resulting in a higher density and thus more air per unit volume to enhance combustion. As a result, more power is obtained, ie performance is improved. [0003] The water used for injection needs to be stored on the vehicle, often for an extended period of time, before all the water is used for injection. It is known to add additives to water to maintain the water in proper condition. However, such additives...
