Oil catch can

Abstract

A catch can assembly for a vehicle comprises a quadrilateral housing having a top unit coupled to a bottom unit for forming a quadrilateral interior volume, the housing having an input for receive a mixture of oil and air and an output for outputting the air; a filter at the interior volume for separating the oil from the air so that the oil collects at the bottom unit; a bracket coupled to the quadrilateral housing for aligning the quadrilateral housing relative to a surface of the vehicle; and a window in the bottom unit for viewing a level of the oil collected at the bottom unit.

What is claimed is: 
     
         1 . A catch can assembly for a vehicle, comprising:
 a quadrilateral housing having a top unit coupled to a bottom unit for forming a quadrilateral interior volume, the housing having an input for receive a mixture of oil and air and an output for outputting the air;   a filter at the interior volume for separating the oil from the air so that the oil collects at the bottom unit;   a bracket coupled to the quadrilateral housing for aligning the quadrilateral housing relative to a surface of the vehicle; and   a window in the bottom unit for viewing a level of the oil collected at the bottom unit.   
     
     
         2 . The catch can assembly of  claim 1 , further comprising a bezel about the window, the bezel including machine marks for identifying a volume of oil in the bottom unit. 
     
     
         3 . The catch can assembly of  claim 1 , wherein the bottom unit includes an opening, and wherein the catch can assembly further comprising at least one o-ring about the opening to provide a seal between the window and the opening. 
     
     
         4 . The catch can assembly of  claim 1 , wherein the vehicle is an automobile. 
     
     
         5 . The catch can assembly of  claim 1 , wherein the vehicle is a motorcycle. 
     
     
         6 . The catch can assembly of  claim 1 , further comprising a drain hole and a drain plug at the drain hole for preventing oil from escaping the bottom unit. 
     
     
         7 . A catch can assembly for a motorcycle, comprising:
 a housing having a top unit coupled to a bottom unit for forming an interior volume, the housing having an input for receive a mixture of oil and air and an output for outputting the air;   a filter at the interior volume for separating the oil from the air so that the oil collects at the bottom unit;   a bracket coupled to the quadrilateral housing for aligning the quadrilateral housing relative to a surface of the vehicle, wherein the bottom unit has an extension for coupling to an air filter backing plate of the motorcycle.   
     
     
         8 . A vehicle, comprising:
 an engine;   an intake system; and   a catch can, comprising:
 an inlet from a valve cover or crankcase of the vehicle; 
 an outlet to an induction system, breather, or manifold of the vehicle; 
 a quadrilateral housing having a top unit coupled to a bottom unit for forming a quadrilateral interior volume, the housing having an input for receive a mixture of oil and air and an output for outputting the air; 
 a filter at the interior volume for separating the oil from the air so that the oil collects at the bottom unit; 
 a bracket coupled to the quadrilateral housing for aligning the quadrilateral housing relative to a surface of the vehicle; and 
 a window in the bottom unit for viewing a level of the oil collected at the bottom unit.
