A noise attenuator which can reduce time and cost for installation thereof as compared with the conventional configuration and a vehicle air intake duct provided with the noise attenuator are provided. The noise attenuator includes a pair of circular through holes formed through a duct wall, a pair of wave transmitting/receiving membrane which are stretched so as to close the circular through holes, and a seesaw member which connects between central portions of the paired transmitting/receiving membranes. Accordingly, when one of the membranes receives a sound wave of noise thereby to be vibrated at a predetermined frequency, the other membrane follows it and is also vibrated while shifted by a half cycle. As a result, a cancellation wave with a phase opposite to the sound wave received by the one membrane is transmitted from the other membrane, whereupon the noise can be attenuated.

An apparatus and a system is provided that may be utilized to determine air flow through an air filter and/or a plurality of air filters. The present invention utilizes a demonstration apparatus to illustrate the differences in air flow and air restriction between a plurality of different air filters and filtration media. The apparatus and system utilizes a common plenum which subjects the plurality of air filters to the same differential pressure. The air flows through a first side of the air filter and is measured on the second side of the air filter by utilizing a wind meter or similar device to gauge the amount of air flow velocity of the second side of the filter. Additionally, the apparatus and system utilizes a display means to illustrate the differing air velocity through the second side of the air filter.

When a deterioration determination apparatus determines a degree of deterioration in characteristics of an airflow meter, a driving condition of an engine is maintained at a specified condition in which intake air flow rate is greater than a specified value. A measurement error of the airflow meter is computed based on an intake air flow rate measured with the airflow meter. The degree of deterioration due to stain is determined based on the measurement error.

An intake system of an engine may include an intake line that is configured to supply cylinder of an engine with air, an exhaust line that exhaust gas combusted in the cylinder is exhausted, a housing disposed on the intake line and a compressor is disposed therein, the compressor is operated by a turbine disposed on an exhaust line, a recirculation line that recirculates the air from the intake line of a downstream side of the compressor to the intake line of an upstream side of the compressor, and an anti surge valve disposed on the recirculation line to open/close the recirculation line, wherein a length of a first section (l) that is straight from the anti surge valve is longer than two times the outlet diameter (d) of the anti surge valve in the recirculation line that is formed from the anti surge valve to an upstream side of the compressor. A distance (L) from the intake line that is connected to the recirculation line to the inlet of the housing may be longer than times the inlet diameter (D) of the housing that the compressor is disposed therein. Accordingly, while the intake air circulates the anti surge valve during a tip-out or acceleration period, the turbulent flow may be decreased and the flowing becomes smooth such that the noise is decreased and the emotional quality may be improved in the intake system of the engine.

Intake system for internal combustion engine

Номер: US20120180746A1
Автор: Masakazu Tanaka, Naoto Yamagishi
Принадлежит: Honda Motor Co Ltd

An intake system for an internal combustion engine, having a structure in which blow-by oil and/or fuel entering into an air cleaner case can be discharged to the outside of the air cleaner case. The intake system for an internal combustion engine is provided in which air is sucked from a clean air chamber in the air cleaner case into a throttle body provided with a throttle valve through a funnel while defining an airflow passage. Concurrently, fuel is sprayed from an injector, thereby feeding the fuel-air mixture into an intake port. A bypass passage different from the airflow passage is provided between the clean air chamber in the air cleaner case and the throttle body. The bypass passage is so structured that a passage inlet thereof on the clean air chamber side opens at an inner wall surface of the air cleaner case.

A throttle body fuel injection system and method that is arranged to easily replace four-barrel carburetors includes a throttle body assembly with four main bores, each with a throttle plate and an associated fuel injector. Each injector feeds fuel into a circular fuel distribution ring via a fuel injection conduit, which introduces pressurized fuel into the air stream. The fuel distribution rings and bores have profiles that avoid constrictions for to prevent low pressure zones according to the Venturi effect. Fuel is injected through downward-facing outlets at or near the bottom end of the rings. The fuel injection rings are two-piece, each formed of an insert pressed into an outer housing. The insert includes axial grooves intervaled about its exterior circumference of insert that are joined by a circumferential groove formed about the insert. The grooves are in fluid communication with a conduit that supplies fuel from a fuel injector.

A locking sealing arrangement for providing a fluid tight seal between a cap or a spigot and an adjacent structure is set forth. The locking sealing cap includes a peripheral sealing member such as an o-ring to form the fluid tight seal. The locking sealing cap engages the inner surface of the adjacent support structure by a cam-lock arrangement. A locking tab extends from the surface of the support structure. A tab-receiving slot is formed in the locking sealing cap. Once the locking tab is aligned in the tab-receiving slot, rotational movement of the locking sealing cap causes engagement of the locking sealing cap with the support structure. One embodiment of the locking sealing cap includes an internal torque feature for receiving a tool to allow engagement. In another embodiment of the locking sealing cap an external, multi-sided tool engagement surface is provided. 1.
