Embodiment Construction

[0028]Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the diesel exhaust particulate filter. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for performing field tests to determine whether a semi-truck diesel engine particle filter is functioning properly. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

[0029]Referring now to FIG. 1, there is shown a perspective view of the present invention. The present diesel exhaust particulate filter comprises an elongated pole 11 having a first end 31 and a second 32, a rigid, annular service ring 14 disposed at the first end 31, and a filtration means 12 removably affixed to the service ring 14. The elongated pole 11 is preferably composed of a rigid material so that users can more easily ex...

Abstract

A method and device for testing a diesel engine to determine whether the engine's diesel particulate filter is functioning properly is provided. The device comprises an elongated pole with a service ring disposed at one end. The service ring is designed to removably support a filtration means, which is composed of porous cloth material. The device is removably affixed over the outlet of a diesel engine exhaust pipe, allowing the filtration means to trap any particulates that may be contained within the engine exhaust. If the diesel engine particulate filter is functioning properly, there will be no particulates collected by the filtration means; if the diesel engine particulate filter is not functioning properly, the present invention allows the user to collect physical evidence of such.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 768,954 filed on Feb. 25, 2013, entitled “Diesel Particular Filter Field Test Kit.” The above identified patent application is herein incorporated by reference in its entirety to provide continuity of disclosure.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to filtering devices. More specifically, the present invention relates to devices for testing diesel engine exhaust for particulates.[0004]Diesel engines generate particulates, which are expelled from the engine via the exhaust, due to incomplete combustion of the diesel fuel. Such particulates cause harmful air pollution, thus all modern diesel engines are fitted with a diesel particulate filter to prevent these particulates from entering the atmosphere. However, if the diesel particulate filter is not functioning properly, whether due to over accumulation of parti...
