Patent ID: 7674341

Claim:
An apparatus for cleaning an internal combustion engine, fuel system and emission system comprising: a first vessel including a first cleaning fluid, the first vessel being in fluid communication with a first cleaning fluid flow path, wherein the first cleaning fluid includes at least one of: (a) an engine fuel component enriched in aromatic compounds and (b) an engine fuel component enriched in aliphatic compounds; a second vessel including a second different cleaning fluid, the second vessel being in fluid communication with a second different cleaning fluid flow path; and an electrode positioned in the second different cleaning fluid flow path, the electrode configured to apply an electrostatic charge to the second cleaning fluid, wherein both the first cleaning fluid flow path and the second different cleaning fluid flow path are in fluid communication with a same fluid delivery conduit configured to attach to a fuel line of the internal combustion engine, and wherein the apparatus is configured to deliver through the fluid delivery conduit both the first cleaning fluid and the electrostatically charged second cleaning fluid to the internal combustion engine in a fuel line and emission system cleaning process.
