An intake system component includes a side wall and a holding sheet arranged on an inner surface of the side wall. The side wall is formed by a fibrous body including base material fibers and binder fibers that bond together the base material fibers. The binder fibers have a lower melting point than the base material fibers. The holding sheet is formed in the same manner as the side wall by a fibrous body including the base material fibers and the binder fibers that bond together the base material fibers. The binder fibers have a lower melting point than the base material fibers. The holding sheet includes a holding portion and a joined portion. The holding portion holds an adsorbent that adsorbs a fuel component. The joined portion is located around the holding portion and joined with the inner surface of the side wall by the binder fibers.

An injector arrangement structure includes an air cleaner which is arranged at a rear side of an engine for a vehicle, a rear suspension which extends vertically at the rear side of the engine, and a first injector which is attached to the air cleaner. The air cleaner includes an outlet tube configuring a clean side of the air cleaner. The rear suspension and the outlet tube overlap each other in a side view. A partition wall dividing an intake passage vertically is provided inside the outlet tube. The first injector is attached from a lower side of the outlet tube so as to inject fuel toward the partition wall.

An apparatus for reducing fuel evaporation gas using a closeable path structure, which is configured such that a path through which fuel evaporation gas can flow is narrowed when an engine stops, may include an intake pipe through which air is drawn into the engine, and an openable door disposed to open or close the intake pipe and configured such that, when the engine is operated, the openable door opens the intake pipe, and when the engine is stopped, the openable door closes the intake pipe, wherein a fuel evaporation gas trap configured to collect the fuel evaporation gas may be disposed on an internal wall of a portion of the intake pipe on which the openable door is disposed.

The present invention discloses an internal combustion engine, comprising a compressor, a combustion chamber, a pipeline, a spray pipe, an oil feeder, a driving device, a first safety device, a second safety device, an electric ignition device, a rack, a first bracket arranged on a top of the rack, a second bracket arranged on an upper part of the rack, a third bracket arranged on a lower part of the rack and a fourth bracket arranged on a left part of the rack. The compressor comprises an inner shell and an outer shell, wherein the inner shell comprises an upper pressing plate and a cylindrical plate; the cylindrical plate can move up and down in the cylindrical plate slot; and an outlet is formed in a non-protruding part at the bottom of the outer shell. The internal combustion engine has simple structure and high efficiency.

A power train system includes a heat exchanger reservoir to collect condensate, a layered intake manifold, and integral tubing leading from the reservoir to an interior of the intake manifold via an intake manifold wall such that there is no seal between the condensate port and the manifold. The tubing splits into at least two branches transitioning into a set of wings containing a plurality of nozzles protruding into the interior.

A condensation dispersion device for a turbocharged vehicle engine includes a valve body, a movable valve, and a biasing means. The movable valve and biasing means are disposed within the valve body. The valve body defines a valve seat within the valve body, and includes an inlet and an outlet. The movable valve defines an engagement feature operatively configured to engage with the valve seat when the movable valve is in a first position. The biasing means is operatively configured to urge the movable valve to a second position when the pressure in the intake manifold is equal to or greater than atmospheric pressure.

The present disclosure provides a fuel injection unit for an internal combustion engine. The fuel injection unit includes: a separator that is disposed in an intake port to supply air into a combustion chamber formed in an engine head, and that divides a channel for air into an upper channel and a lower channel; a blade disposed ahead of the separator and opening or closing the upper channel or the lower channel by rotating; and a first injector disposed over the intake port. In particular, when the first injector injects fuel, the blade does not interfere with the fuel.

A combined mass airflow sensor and hydrocarbon trap is provided for absorbing evaporative hydrocarbon emissions from an air intake duct of an internal combustion engine. The combined mass airflow sensor and hydrocarbon trap comprises a duct that supports a hydrocarbon absorbing sheet in an unfolded configuration within a housing. The duct communicates an airstream from an air filter to the air intake duct during operation of the internal combustion engine. An opening in the housing receives a mass airflow sensor into the duct, such that the mass airflow sensor is disposed within the airstream. Guide vanes extending across the duct reduce air turbulence within the airstream passing by the mass airflow sensor. Ports disposed along the duct allow the evaporative hydrocarbon emissions to be drawn into the interior and arrested by the hydrocarbon absorbing sheet when the internal combustion engine is not operating.
