Embodiment Construction

[0016] exist figure 1 A block diagram of a motor vehicle generally designated 10 is shown in . The motor vehicle described includes an air intake system generally indicated at 12 for receiving air via an air intake 14 to supply air to facilitate combustion in an engine (not shown). The air intake system also has an air cleaner 16 and an oil vapor adsorption or absorption device generally indicated as 20, the oil vapor adsorption device includes an oil vapor adsorption member 22 for adsorbing the air in the air intake system 12 after the engine is shut down. Any unburned fuel.

[0017] Referring now to Figures 2-4, a first embodiment of an oil vapor adsorption member is shown. The oil and gas adsorption member 22 includes an outer cylinder or outer member 24, an inner cylinder or inner member 26, and an intermediate member or folded member 28, the inner cylinder 26 is located in the outer cylinder 24 so that the inner cylinder and The outer cylinders have a common axis A, an...

Abstract

A hydrocarbon adsorbing device capable or adsorbing or absorbing and subsequently releasing hydrocarbons in the induction system of a motor vehicle. In one embodiment, the hydrocarbon adsorbing device includes an inner cylinder of hydrocarbon adsorbing material and an outer cylinder of hydrocarbon adsorbing material. The inner cylinder is located within the outer cylinder. The hydrocarbon adsorbing device also includes an intermediate member of hydrocarbon adsorbing material that is located between the inner cylinder and the outer cylinder. The intermediate member may be attached to both the outer cylinder and the inner cylinder and be folded in a pleated fashion. In one embodiment, the intermediate member extends completely about the inner cylinder. The hydrocarbon adsorbing device may also include a flange attached to and extending outwardly from the outer cylinder for use in locating the hydrocarbon adsorbing device in the induction system.

Description

technical field [0001] The present invention relates to an oil gas or hydrocarbon adsorption or absorption device that can be used in the air intake system of a motor vehicle, in particular, to an oil gas adsorption device with a structure that can increase the surface area of ​​the adsorption material. Background technique [0002] Efforts are continually being made to reduce emissions from internal combustion engines. One way in which emissions are expelled from the internal combustion engine is when the internal combustion engine is turned off. Fuel that has been sprayed from the injectors, but was not burned before the engine was shut down, evaporates outward through the intake manifold, intake line and air filter, and eventually escapes into the atmosphere and causes air pollution. [0003] In an effort to reduce such undesirable evaporative slip, many types of filters have been developed. Examples of filters for use in vehicle air intake systems can be found in U.S. ...
