A cleaning apparatus includes a wash chamber, a platform and a lid. The platform is disposed in the chamber and sized to support an engine block. The lid has a first portion rotatably coupled to the wash chamber and a second portion rotatably coupled to the first portion. When the first portion of the lid is disposed in a position rotated distal to the wash chamber, the second portion of the lid is disposed in a position rotated proximal to the first portion of the lid. When the first portion of the lid is disposed in a position rotated proximal to the wash chamber, the second portion of the lid is disposed in a position rotated distal to the first portion of the lid.

The invention includes a system to reduce deposits from a surface of an intake valve, preferably in a GDI engine. The system includes a delivery device having a reservoir for holding a cleaning agent. The reservoir has a body that defines an interior space, and an outlet port in fluid communication with the interior space of the reservoir body. The delivery device has a delivery conduit that extends from the outlet port and terminates at a distal end. The proximal end of the delivery conduit is in fluid communication with the outlet port. An actuator having an open position and a closed position is included in the delivery device. Upon activation of the actuator from a closed position to an open position, a portion of the cleaning agent flows from the interior space through the outlet port and is delivered under pressure to distal end of the delivery conduit.

The present disclosure relates to an adapter that is attachable to an engine vacuum source (e.g., insertable into an end of a vehicle-engine vacuum hose) to receive a cleaning fluid from a canister (e.g., aerosol can) and to meter the cleaning fluid into the vacuum source. The adapter may include a vacuum-source insert and a nozzle receiver. In addition, the adapter may include a fluid path between the vacuum-source insert and the nozzle receiver that meters a flow of cleaning fluid.

A descaling method involves a tool for diagnosing the engine of a motor vehicle, which tool can interact with the control electronics system of the engine, not only for reading information and controlling certain members during a hydrogen injection cleaning procedure, but also for checking, in real time after cleaning, the state of the impacted members and updating the engine management parameters accordingly in the control electronics system. Thus, the electronic management of the engine may take account of the resetting (i.e. to the initial values or values close to the initial values) of the operating parameters of the engine which are sensitive to engine scaling, such as EGR valve mobility, valve lift, DPF clogging, injector needle mobility, etc.

An apparatus and method used to maintain an engine coolant system and related components, which may be easily and quickly connected to multiple configurations and sizes, whereby an engine forward flushing can be accomplished.

The cleaning agent includes a detergent, a carrier, and an oil. In a preferred embodiment, the system is an aerosolized. Also contemplated with the scope of the invention are related methods of removing deposits from the surface of an intake valve and/or of enhancing or improving engine performance.

A system and method for cleaning deposits, such as carbon build-up, from an air induction path of a motor vehicle engine. A reservoir mounted onboard the vehicle is in fluid communication with the induction path and contains a cleaning solution. A control module activates a valve to meters a flow of the solution into an air intake plenum in response to a signal indicating a parameter related to operation of the engine. The solvent may be delivered in a quantity calculated to collect at sump of the intake plenum and be drawn into the engine when intake air flow exceeds a threshold rate. The engine-related parameter may be distance travelled by the vehicle.

An attachment for purging the inside of the carburetors which is comprised by a tubular device having a carburetor connecting member and quick connect receiver extension. The attachment is connected through the bottom of the carburetor or through the feed fuel line of the carburetor. The attachment is attachable to a quick disconnect fitting which can be connected to a conventional car tire air nozzle or pressurized can with the same fitting as the car tire nozzle. The attachment allows all the jets and passages located on the inside of carburetor to be purged at the same time with multiple short blasts of compressed air or pressurized can solvent but without the carburetor being removed from the engine or taken a part. The same principles can easily be applied to all type carburetors for either a two or four-stroke engine.

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.
