Abstract: An internal combustion engine having pistons, cylinders, an air cooler, an air manifold and a turbocharger with a compressor. There is a tank to contain hot water under pressure. The pressure in the tank and the water temperature can be controlled. At least one injector allows heated water to be injected into the turbocharger compressor. A further injector allows water to be injected into the air cooler and a plurality of yet further injectors allow water to be injected into the air manifold. Conduits supply water from the tank to the injectors. Control of flow in the conduits is by valves. The invention permits the cleaning of an internal combustion engine without dismantling the engine or the turbocharger.

Abstract: An anti-pollution system for an internal combustion engine wherein a container within which is a body of water has an air injection system including first tubing extending into the container, second tubing connected to extract combustion gases from the engine exhaust system to introduce them into the container, third tubing extending from within the container to the engine intake system to subject the interior of the container to vacuum, and a heater energized from the vehicle ignition system for heating the body of water, so that during engine operation combustion gases are introduced into the container where they are cleansed, enriched with air and passed into the fuel intake system.
