ABSTRACT:
An electronically controlled carbon-cleaning apparatus for removal of carbon deposits in internal combustion engines. A microcomputer and associated electronics perform all control, and user interface functions. Firmware provides self test, automatic voltage adjustment to direct current systems used on internal combustion engines. The apparatus includes a fill feature whereby a solution tank is filled automatically. The apparatus circulates a fuel-cleaner solution through the fuel injection system of the engine while it is operated, thereby saving the time and cost associated with the removal and hand cleaning of injectors. Fuel-cleaner solution level and run time are continuously monitored by the microcomputer and displayed on a LCD display. Solution pressure is continuously monitored and necessary adjustments automatically made while circulating fuel-cleaner solution. An engine cut-off solenoid driver is provided to shut down the engine in the event of a empty solution tank. An audio alarm comprised of two unique sets of frequencies alerts the operator when necessary.
