METHOD FOR CLEANING ENGINE DEPOSITS
First Claim
1. A method for removing deposits on a combustion engine, comprising:
- coupling a data cable to an on-board diagnostic port on a vehicle;
coupling a service hose from a cleaning apparatus to a first port on the vehicle;
operating the vehicle engine at a predetermined engine rpm;
monitoring, by a controller, data from an on-board diagnostic port on a vehicle, wherein the data includes engine rpm, a catalytic convertor temperature, engine coolant temperature, mass air flow, and manifold absolute pressure;
monitoring, by the controller, information from the cleaning apparatus, wherein the information is associated with the dispensing of the cleaning solution including at least one of a rate, a volume, a pressure, a pulse interval, a flow pattern and a time; and
dispensing, by the controller, a cleaning solution through the service hose to the first port on the vehicle;
wherein the information is increased or decreased by the controller during the dispensing, in response to the data.

Abstract
A method for cleaning a combustion engine using a cleaning apparatus, wherein 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.
