Embodiment Construction

[0016] The following description is merely exemplary in nature and is not intended to limit the disclosure, usage, or methods of use. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0017] First refer to figure 1 , shows an exhaust system 10 for an engine 12 . The exhaust system 10 and the engine 12 are installed in an automobile. The engine 12 generates torque to move the vehicle. As will be described in more detail below, the exhaust system 10 receives exhaust from the engine 12 and figure 1 denoted as "ATM") before processing it.

[0018] The engine 12 includes a plurality of combustion chambers 14a, 14b, 14c. In the illustrated embodiment, the engine 12 includes a first combustion chamber 14a, a second combustion chamber 14b, and a third combustion chamber 14c. However, it will be appreciated that the engine 12 may include any number of combustion chambers 14a, 14b, 14c withou...

Abstract

An exhaust system for an engine with a plurality of combustion chambers. The exhaust system includes a first emission treatment device in fluid communication with at least one of the combustion chambers so as to receive exhaust therefrom. The exhaust system further includes a second emission treatment device in fluid communication with at least one other of the combustion chambers so as to receive exhaust therefrom. The second emission treatment device is also in fluid communication with a downstream end of the first emission treatment device so as to receive exhaust therefrom.

Description

field of invention [0001] The present disclosure relates to an exhaust system, and more particularly, to an exhaust system having a plurality of emission treatment devices. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] It is known to provide an engine with an exhaust system with an exhaust gas treatment device. For example, an engine includes a diesel particulate filter (“DPF”), a diesel oxidation catalyst (“DOC”), a selective catalytic reduction (“SCR”) device, and / or a three-way catalytic converter ("TWC") exhaust system. These exhaust treatment devices reduce the amount of undesirable materials that flow with the exhaust. [0004] More specifically, a diesel particulate filter generally receives exhaust gas flowing from a combustion chamber of an engine and collects soot contained therein. Periodically, the DPF undergoes a process called re...
