Abstract
The present invention relates to a hydrocarbon trap positioned in the air intake system of a vehicle, upstream from the engine and wholly in the airflow. The hydrocarbon trap comprises a holder and a material for adsorbing the hydrocarbons, inserted inside the holder. The holder comprises a screen that is added at the end facing the engine. The screen is held in place with the help of a locking mechanism. The locking mechanism comprises a locking ramp on the holder and corresponding locking tab on a clamping ring surrounding the holder.
Claims24
A hydrocarbon trapping device positioned in the air intake system of an engine, wherein the device is placed upstream from the engine, the device comprising:
- a housing having a body with a first end and a second end, wherein the engine is closer to the first end of the body than to the second end of the body;
- at least one element having a circumference, the circumference substantially surrounded by the body of the housing, for adsorbing hydrocarbons released by the engine;
- and
- a first screen connected to the housing adjacent to the first end of the body for preventing the element from flowing to the engine.
A hydrocarbon trapping device positioned in the air intake system of an engine, wherein the device is placed upstream from the engine, the device comprising:
- a housing having a body with a first end and a second end, wherein the engine is closer to the first end of the body than to the second end of the body;
- an element housed in the body of the housing for adsorbing hydrocarbons released by the engine;
- a screen coupled with the body;
- and
- a clamping ring attachable around a perimeter of the body of the housing;
- wherein the screen is inserted between an end of the clamping ring and one of the first and second ends of the body.
A hydrocarbon trapping device positioned in an air intake system of an engine, wherein the device is positioned upstream from the engine, the device comprising:
- a housing, wherein the housing defines an inner perimeter surface, a first face facing the engine, and a second face facing away from the engine;
- an element having a circumference, the element configured to adsorb hydrocarbons, wherein the inner perimeter surface of the housing surrounds the circumference of the element between the first face and the second face;
- a first screen attachable to the first face of the housing;
- and
- a cushion ring surrounding the circumference of the element substantially between the housing inner surface and the element, the cushion ring comprising a compliant material.
