Abstract: A device and method for cleaning the air-intake system of an EGR-valve-equipped diesel engine includes a dispersion component which mixes air and a liquid cleaning solution before delivering them to the air intake system of a running diesel engine. A main air intake is blocked and the EGR valve is removed and replaced with a coupler that receives the dispersion component, whereby a pressure drop is created. The pressure drop creates sufficient vacuum so that cleaner may be administered into the air-intake duct of the running engine. The cleaning solution is provided to the dispersion component under pressure supplied by a pressurized air source.

Abstract: A cleaning solution, which is particularly useful in cleaning the air-intake system of an EGR-valve-equipped diesel engine, includes a high-polarity solvent and low polarity solvent. The solution may also include a surfactant, a fatty amide, and a functional ketone. The cleaning solution is applied to the air intake system while the diesel engine is running, thereby drawing the cleaning solution into the air intake system to clean the same. The EGR valve is removed and replaced with a vessel in which a pressure drop is created. The pressure drop creates sufficient vacuum so that cleaner may be administered into the air-intake duct of the vehicle.

Abstract: The present invention is directed to a device and method for removing and replacing oil in an engine in a vehicle. The device includes a container and a control system. The container contains a cap assembly, a tubular housing, and a base assembly. The tubular housing is located between the cap and base assemblies and is sealably coupled therewith. The control system includes a pressure system and a transport system. The pressure system includes a pressure gauge, a vent valve, an air valve, and a regulator. The pressure system is connected to an air source. The transport system includes a control valve, an air hose adaptor, and an oil port connector. The transport system is connected to the pressure system via a connector hose. In operation the device operates to remove and replace the oil in a engine prior to startup.

Abstract: Disclosed is a container including a filter which is tapped into the supply and return fuel lines of a vehicle between the tank and the engines fuel injection system. The container is filled with a cleaner which is introduced into the vehicles fuel injection system and cleans the injectors. The system is able to function without the assistance of any other supporting equipment. It simply feeds off of the existing fuel delivery system already existent in the vehicle.
