Abstract
A dispensing apparatus is disclosed for adding a fluid agent to the fuel supply of an automotive engine, the agent is effective in depressing the ignition temperature of soot collected in an exhaust trap. The apparatus comprises: (a) a reservoir for containing a supply of the fluid agent such as copper octoate and hexane; (b) an electrically operated pulse pump for positively displacing a measured amount of the agent from the reservoir into the fuel supply; (c) register means for registering the amount of fuel replenished to the engine fuel supply and for transmitting an electrical signal proportional to the amount of fuel so added; and (d) control means responsive to the electrical signal to permit electrical operation of the pulse pump for a number of predetermined pulses to dispense a required amount of the agent for maintaining a desired uniform concentration of the agent throughout the fuel supply.
