Systems for the reduction or elimination of intake valve deposits in gasoline direct injection engines and related methods

摘要

The invention includes a system to reduce deposits from a surface of an intake valve, preferably in a GDI engine. The system includes a delivery device having a reservoir for holding a cleaning agent. The reservoir has a body that defines an interior space, and an outlet port in fluid communication with the interior space of the reservoir body. The delivery device has a delivery conduit that extends from the outlet port and terminates at a distal end. The proximal end of the delivery conduit is in fluid communication with the outlet port. An actuator having an open position and a closed position is included in the delivery device. Upon activation of the actuator from a closed position to an open position, a portion of the cleaning agent flows from the interior space through the outlet port and is delivered under pressure to distal end of the delivery conduit. The cleaning agent includes a detergent, a carrier, and an oil. In a preferred embodiment, the system is an aerosolized. Also contemplated with the scope of the invention are related methods of removing deposits from the surface of an intake valve and/or of enhancing or improving engine performance.
