摘要:
A method of operating a control unit of an emission abatement assembly, the method comprising the steps of: monitoring operation of a fuel-fired burner of the emission abatement assembly and determining if predetermined conditions are present, generating an error signal if the predetermined conditions are present, and communicating the error signal to an engine control unit of an engine.

Ein Schalldämpfer, insbesondere für die Abgase einer Verbrennungskraftmaschine, mit einem Gehäuse (14) und mindestens einer im Gehäuse angeordneten Hohlkammerstruktur (20), ist dadurch gekennzeichnet, daß das Gehäuse (14) mit mindestens einem nach innen ragenden Vorsprung (24) versehen ist, mittels dem die Hohlkammerstruktur (20) im Inneren des Gehäuses (14) arretiert ist.
摘要:
A powertrain control system (10) is provided that includes an engine (12) having multiple cylinders (14). A controller (24) selectively activates the cylinders (14) to provide a cylinder combination having a desired power displacement. In one example powertrain control system (10), the controller (24) selectively activates the cylinders between a V-8 and V-4 mode. An exhaust system (17) having a valve (28) and an electrical actuator (26) selectively electrically actuates the valve (28) in response to the controller (24) between multiple positions. The electrical actuator (26) moves the valve (28) from an open position in V-8 mode to a partially closed position in V-4 mode to increase back pressure and reduce noise, vibration and harshness issues in V-4 mode. A muffler (20) includes a housing (30) having an exhaust passage. The valve (28) is supported by the housing (30) and arranged in the exhaust passage. The valve (28) is moveable between multiple positions for tuning the muffler (20). The electrical actuator (26) is supported by the housing (30) to actuate the valve (28) between the multiple positions.

A filter apparatus (10) comprises a housing (18), a filter element (14), and an anti-drainback valve (24). The anti-drainback valve (24) comprises a support member (92) and a valve member (30) coupled to the support member (92) for movement between a normally closed position blocking a flow of fluid out of the housing through an inlet formed in the housing and an opened position allowing a flow of fluid through the inlet into the housing.
摘要:
A fluid filter assembly including a canister having a first passage and a second passage. A filter element is disposed within the canister and defines a bore, which is aligned with and in communication with the first passage. An end-cap is mounted on the end of the filter element and has a center portion, which is aligned with the bore of the filter element and has at least one bypass hole. A washer valve is mounted on the center portion of the end-cap, and has a closed position, wherein the washer valve sits flush against the end-cap sealing the at least one bypass hole from the bore, and an open position, wherein the washer valve deflects away from the end-cap exposing the at least one bypass hole to the bore.
摘要:
An exhaust pipe valve having a housing (12), a bearing sleeve (22) mounted in the housing, a valve spindle (16) rotatably mounted in the bearing sleeve, and a valve plate (14) mounted at the valve spindle, the bearing sleeve (22) having a primary bearing surface (24) on its side facing the valve plate, the valve spindle having a primary sealing surface (20) cooperating with the primary bearing surface of the bearing sleeve, a washer (30) being arranged on the valve spindle for cooperation with the bearing sleeve on its side facing away from the valve plate, and a spring (32) being provided which biases the primary sealing surface (20) of the valve spindle (14) against the primary bearing surface (24) of the bearing sleeve (22) while biasing the washer (30) against the bearing sleeve (22).
