ABSTRACT:
An electronically controlled carbon-cleaning apparatus for removal of carbon deposits in internal combustion engines. A microcomputer and associated electronics controls the solenoid valve and pump motor. The microcomputer performs all user interface functions. Firmware provides self test, automatic voltage verification and a variety of safety features. The apparatus includes a fill feature whereby a solution tank is filled automatically. The apparatus is designed to gradually provide power to the pump so that leaks or faulty connections can be detected before the pump reaches full pressure. 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 LED display. Fuel-cleaner solution pressure is continuously monitored for leaks due to faulty hose connections. An automated leak test feature allows the user to check for leaks in the fuel injectors and pressure control valve without removing them from the engine. An audio alarm comprised of many unique sets of frequencies alerts the operator when necessary.
