A fugitive hydrocarbon treatment module and system for controlling the emission of hydrocarbons from the air intake system of an engine includes a zeolite adsorber unit positioned in the air intake system such that all gases flowing to and from the engine through the air intake system pass through the adsorber, so as to allow hydrocarbons borne by the gases to be adsorbed upon the substrate of the adsorber unit when the engine is shut down and desorbed from the adsorber unit when the engine is in operation.

Fugitive hydrocarbon treatment module for internal combustion engine air intake system

A hydrocarbon sensor and collector. An element that is capable of absorbing and releasing hydrocarbons is positioned in the air intake system of a vehicle, upstream from the engine and wholly in the airflow. The element has a plurality of chambers defined in it that allow air to pass through the element. The hydrocarbon sensor and collector also includes a means for detecting the level of hydrocarbons absorbed by the element.

Hydrocarbon sensor and collector

A vapor evacuation system that is used to intermittently remove hydrocarbon vapors from vehicle components to an available vapor storage canister using an electrically controlled small flow rate vapor-handling pump. The vapor-handling pump is intermittently turned on and off as a function of ambient temperature or inlet manifold temperature and as a function of time since last engine-on operation.

Hydrocarbon vapor evacuation system

A system and method is disclosed for measuring mass of hydrocarbons from point source contributions to overall hydrocarbon emissions from an automotive vehicle at rest.

Method and apparatus for measuring a gaseous component emanating from a vehicle

An evaporative emissions canister includes a housing containing a hydrocarbon adsorbing material, such as carbon. The canister may be configured to such that a portion acts as a buffer canister of such that the entire canister is used to adsorb hydrocarbon emissions. The canister housing is generally cylindrical with a reduced cross-sectional area portion and is configured in a manner to allow flow along a relatively straight line.

Evaporative emission canister for an automotive vehicle

An evaporative emissions canister includes a housing containing a hydrocarbon adsorbing material, such as carbon. The canister may be configured to such that a portion acts as a buffer canister of such that the entire canister is used to adsorb hydrocarbon emissions. The canister housing is generally cylindrical with a reduced cross-sectional area portion and is configured in a manner to allow flow along a relatively straight line; with both features acting to increase purge efficiency and reduce restriction, respectively.

An automotive evaporative emissions canister includes a housing containing a hydrocarbon adsorbing material, such as carbon. The canister includes a vent port for venting air to the atmosphere upon adsorption of hydrocarbons and for admitting air upon the desorption of hydrocarbon during the purging operation of the canister. A purge port is adapted for connection to the engine to allow the desorbed hydrocarbons to flow into the engine. A plurality of holes is formed through the side wall of the canister housing and are formed at a location remote from the purge port between the vent port and the purge port to define a buffer zone. The holes are adapted for communication with the fuel tank to allow fuel vapor to flow through the tank through the plurality of holes into the buffer zone. Thus, vapor purged directly from the tank to the engine is buffered through the carbon canister to prevent any vapor purge spikes creating the undesirably over-rich condition.

A fuel vapor recovery system for an automotive vehicle includes a fuel tank, a first vapor recovery canister, a second vapor recovery canister, and a bypass flow metering element. The first canister has an inlet communicating directly with the fuel tank and an outlet. The second canister has an inlet communicating directly with the outlet of the first canister. The bypass flow metering element is disposed between the inlet and outlet of the first canister and directs a predetermined portion of the vapor from the tank directly to the inlet of the second canister, thereby reducing the vapor flow restriction through the system.

Fuel vapor recovery system

An evaporative emission control system for an automotive vehicle includes a generally cylindrical casing having an adsorption zone containing hydrocarbon adsorbing agent, an antechamber extending within the casing to the adsorption zone, and a swirl inducing inlet passage for conduction of hydrocarbon laden air into the antechamber such that a rotational flow pattern will be established in the antechamber, with the rotational flow having an axis coincident with a longitudinal axis of the generally cylindrical casing.
