This invention relates to the field of induction cleaning, more particularly to chemically cleaning the induction system of the internal combustion engine. The carbon that accumulates within the induction tract of the internal combustion engine is very difficult to remove. Chemically these carbon deposits are very close to that of asphalt or bitumen. It has been found that if the induction cleaning chemicals are delivered in timed layered intervals the removal of such induction carbon can be accomplished. The Dual Solenoid Induction Cleaner uses electronically controlled solenoids to deliver at least two different chemistries in alternating layers to the engine's induction system. These electric solenoids are connected to a single induction cleaner nozzle. The induction cleaner nozzle is slipped through the vacuum port opening into the inside of the induction system where it will spray an aerosol of the chemistry directly into the moving air column entering the engine.

A ventilation apparatus of an internal combustion engine of the invention ventilates a chain chamber by recirculating blow-by gas to an intake passage through a blow-by gas recirculation pipe and introducing air into the chain chamber through an air introduction pipe. The air introduction pipe is secured to a head cover wall portion which corresponds to a portion of a head cover wall which defines the chain chamber.

The presently disclosed subject matter is generally directed to a system and method of protecting vehicle engines by preventing water from entering the belt drive and/or air intake of the vehicle motor. The disclosed system includes a housing and one or more snorkels that extend in an upward direction from the housing. Each snorkel includes a water sensor that detects the level of water outside of the vehicle. When water reaches the snorkel maximum depth and triggers the sensor, valve within the housing closes to divert water away from the motor. Once the vehicle is back on dry land, the user can reset the valve to the open position.

A cooling device includes a surrounding member, an air inlet, an air outlet, and a flow-path-formation mechanism. The surrounding member is configured to surround an engine. The air inlet is formed in the surrounding member. The air outlet is formed in the surrounding member and is to be coupled to an intake pipe of the engine. The flow-path-formation mechanism is configured to form a flow path that allows outside air to circulate to the air outlet from the air inlet when a temperature of the engine or a temperature inside the surrounding member is greater than or equal to a predetermined temperature.

An improved hydrogen oxygen generator used for converting water to hydrogen gas and oxygen gas, which is mixed with fuel in a vehicle engine for improved mileage and cleaner burning fuel. The generator includes a water bottle. Water from the water bottle is fed by gravity through a water line, with an inline water line orifice adapter. The water line is connected to a threaded water line nipple. The water line nipple is attached to a solenoid valve. The solenoid valve is used for heating the water, in a range of 100 to 150 degrees F., and is connected to a wireless signal receiver, for receiving a remote signal for turning the generator “on” and “off”. A gas generator nipple is attached to the solenoid valve and to a side of an engine manifold. The generator nipple is used for creating hydrogen gas and oxygen gas from the heater water and then introducing the heated hydrogen and oxygen gas with engine fuel inside the manifold.

An internal combustion engine is provided with: two intake pipe portions for guiding intake air to two banks; and a blow-by gas recirculation pathway for leading blow-by gas to the two intake pipe portions from a cylinder head or a crank case that includes the two banks. The blow-by gas recirculation pathway includes a distribution passage which is provided between the two intake pipe portions, and which distributes the blow-by gas and allows the same to flow to the two intake pipe portions.

This compressed air generation system (12) for an automotive vehicle (V) comprises: —a turbocompressor (4) feeding an internal combustion engine (2) of the automotive vehicle (V) with compressed air, —an air compressor (8), —at least one compressed air tank (10) connected to an outlet pipe (82) of the air compressor (8), the air compressor (8) comprising an inlet pipe (80) fed with compressed air from the turbocompressor (4). The compressed air generation system (12) comprises a pressure regulator (14) placed downstream the turbocompressor (4) and upstream the air compressor (8) and which limits the pressure (P8) of the compressed air fed from the turbocompressor (4) to the air compressor (8) to a first threshold (T1).

The invention relates to a plug assembly (1), in particular for use in a vehicle, comprising a tube (3), a sealing element (5) and a plug connector (4), which comprises a connector body (6), wherein the connector body (6) has an annulus (22) located between a first casing section (12) and a second casing section (15) of the plug connector (4), wherein a connection section (33) of the tube (3) is introduced into the annulus (22) of the connector body (6) and the sealing element (5) is arranged between the first casing section (12) and the connection section (33) of the tube (3). The first casing section (12) of the connector body (6) is deformed in such a way that an interlocking connection is established between a shaping region (56) of the first casing section (12) of the connector body (6) and the tube (3), wherein the sealing element (5) protrudes at least partially into the shaping region (56) of the first casing section (12), such that the sealing element (5) is clamped at least sectionally between the first casing section (12) and the tube (3).

A resonator includes: an inner pipe having first openings penetrated into an outer peripheral surface thereof from an inner peripheral surface thereof and second openings spaced apart from the first opening; a first cover adapted to allow a first resonant space to be formed between the outer peripheral surface of the inner pipe and the inner peripheral surface thereof, the first resonant space communicating with the internal space of the inner pipe through the first openings; and a second cover adapted to allow a second resonant space to be formed between the outer peripheral surface of the inner pipe and the inner peripheral surface thereof, the second resonant space communicating with the internal space of the inner pipe through the second openings.

The present invention relates to the carbon deposit buildup in the internal combustion engine, or more specifically the removal of such carbon from the induction system, combustion chamber, and the exhaust system. The method is one in which a high volumetric flow rate of chemical/chemical mixes are used to remove a greater amount of carbon from the engine. These preferred chemical/chemical mix flow rates are 6 to 9 Gallons per hour, which is approximately 9 times the volumetric flow rate of the industry standard of 1 gallon per hour.
