This invention relates to cleaning the induction systems, the combustion chambers and exhaust systems of internal combustion engines. And, more particularly, to chemicals and mixtures of chemicals for removing the different types of carbon deposits encountered in internal combustion engines used in “road vehicles”. Carbon deposits were taken from the induction systems of these road vehicles for the purpose of bench testing such carbon and product development. More specifically, chemicals (i.e., solvents) and chemical mixes (i.e., solutions) have been accurately tested on such harvested carbon deposits for their ability to remove the various types of carbon deposits that accumulate within road vehicle internal combustion engines. Additionally this invention also relates to apparatus for delivering chemicals and chemical mixes. Which includes those developed by applicant, as well as those prior art products marketed for carbon removal, to the induction system of vehicles to maximize the effectiveness of the chemical delivery.

An apparatus for cleaning an intake system of an engine includes a pressure-resistant container having a reservoir chargeable with an engine cleaner composition and a discharge orifice for discharging the engine cleaner composition from the reservoir. The apparatus also includes a dispensing assembly including an assembly inlet connectable to the discharge orifice of the pressure-resistant container for receiving the engine cleaner composition discharged from the pressure-resistant container. The dispensing assembly further includes an assembly outlet, and a length of tubing for receiving the engine cleaner composition from the dispensing assembly. The apparatus further includes a timer configured to control a timed valve that, when opened, allows the engine cleaner composition to discharge from the pressure-resistant container. The timer is configured to delay opening of the timed valve for a predetermined period of time after actuation of the timer.

An attachment for an air blow gun includes a nozzle and a nozzle insert. The nozzle is a hollow cylinder and includes radial pinholes at one end. The nozzle insert includes a longitudinal pinhole. The nozzle insert is inserted into the end of the nozzle with the radial pinholes. When high-pressure air is delivered to the attachment, plumes of high-velocity air exit from the radial pinholes and the longitudinal pinhole. The attachment is particularly well suited to cleaning confined spaces in workpieces with high-velocity air.

A method for cleaning a combustion engine is disclosed wherein an apparatus with a cable is coupled to an on-board diagnostic port on the vehicle, and a service hose with a misting nozzle adapter is coupled to a first port on a vehicle. A controller monitors data from the on-board diagnostic port on a vehicle, where the data preferably includes the engine rpm, the catalytic convertor temperature, the engine coolant temperature, the MAF, and the MAP. The controller monitors information from the cleaning apparatus, and the information is processed to adjust the dispensing of the cleaning solution. The adjustment of the cleaning solution can vary the rate, volume, pressure, pulse interval, flow pattern, and duration of the solution in the engine.
