1. A fluid-dispensing device attachable to an air-intake system of an internal combustion engine for introducing an engine cleaner composition into the air intake system, the fluid-dispensing device comprising:
- (i) a pressure-resistant container having a reservoir and a discharge orifice, the reservoir charged with an engine cleaner composition and a propellant;
(i) an on-off valve having an inlet and an outlet, the inlet connected in with the discharge orifice of the pressure-resistant container for receiving engine cleaner composition discharged from the container; and
(ii) a length of flexible tubing having an inlet end and an outlet end and a central bore extending from the inlet end to the outlet end, the inlet end of the tubing connected with the outlet of the valve for receiving engine cleaner composition discharged from the pressure-resistant container through the valve;
wherein the fluid-dispensing device provides a flow rate of engine cleaner composition at the outlet end of the length of flexible tubing ranging from about 25 to about 50 grams per minute.

6. A fluid-dispensing device attachable to an air-intake system of an internal combustion engine for introducing an engine cleaner composition into an air intake system through a vacuum port, the fluid-dispensing device comprising:
-
(a) a container having a reservoir and a discharge orifice, the container charged with an engine cleaner composition;
(b) a length of flexible tubing having an inlet end and an outlet end and a central bore extending from the inlet end to the outlet end, the inlet end of the length of flexible tubing in communication with the reservoir of the container for receiving engine cleaner composition from the reservoir; and
(c) a vacuum port adapter having an inlet end and an outlet end, the inlet end in communication with the outlet end of the flexible tubing and the outlet end adapted to be friction fit within the vacuum port;
wherein the fluid-dispensing device when connected to the air intake plenum of an internal combustion engine providing a vacuum ranging from about 18 to about 22 inches of Hg provides a flow rate of engine cleaner composition ranging from about 25 to about 50 grams per minute. - View Dependent Claims (7, 8, 9, 10)
