Apparatus for cleaning engine deposits
An apparatus for cleaning a combustion engine is disclosed 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.
1. An apparatus for cleaning engine deposits in a vehicle's combustion system, comprising:
a service hose adapted for connection to an inlet port of the combustion system;
a cable adapted for connection to an OBD port of the vehicle; and
a fluid delivery machine connected to the service hose and the cable, the fluid delivery machine further comprising:
an inlet port adapted to connect with a pressurized gas source;
a display;
an air pressure regulator;
an inlet pressure gauge and an outlet pressure gauge;
an OBD board for analyzing a vehicle's engine characteristics received via the cable from the vehicle's OBD port;
a cleaning fluid reservoir;
a solenoid valve;
a cleaning fluid level sensor; and
a controller;
wherein the controller of the fluid delivery machine is configured to obtain from the OBD port of the vehicle an engine revolutions per minute (rpm), and adjust a flow of cleaning fluid from the cleaning fluid reservoir to the inlet port of the vehicle's combustion system based on the engine rpm.
2. The apparatus for cleaning engine deposits of claim 1 , wherein the controller of the fluid delivery machine is configured to adjust flow pattern of the cleaning fluid at the inlet port of the combustion system of the vehicle based on informaton received from the OBD port.
3. The apparatus for cleaning engine deposits of claim 2 , wherein the flow pattern includes a pulde interval.
4. The apparatus for cleaning engine deposits of claim 2 , wherein the flow pattern includes a fluid pressure.

6. The apparatus for cleaning engine deposits of claim 1 , wherein the controller is further configured to obtain from the OBD port of vehicle a catalytic converter temperature, and adjust a flow of cleaning fluid from the cleaning fluid reservoir to the inlet port of the vehicle's combustion system based on the catalytic converter temperature.
7. The apparatus for cleaning engine deposits of claim 1 , wherein the controller is further configured to obtain from the OBD port of the vehicle an engine coolant temperature, and adjust a flow of cleaning fluid from the cleaning fluid reservoir to the inlet port of the vehicle's combustion system based on the engine coolant temperature.
8. The apparatus for cleaning engine deposits of claim 2 , wherein the fluid delivery machine further comprising a source of compressed air.
9. The apparatus for cleaning engine deposits of claim 1 , wherein the controller is further configured to obtain from the OBD port of the vehicle a mass air flow rate, and adjust a flow of cleaning fluid from the cleaning fluid reservoir to the inlet port of the vehicle's combustion system based on the mass air flow rate.
10. The aparatus for cleaning engine deposits of claim 1 , wherein the controller is further configured to obtain from the OBD port the vehicle's manifold absolute pressure, and adjust a flow of cleaning fluid from the cleaning fluid reservoir to the inlet port of the vehicle's combustion system based on the manifold absolute pressure.
