Abstract: An air cleaner assembly with a restriction indicator includes a housing having an exterior surface around an interior volume. The housing includes a bore extending through a portion of the exterior surface of the housing surrounded by a bore wall protruding from the portion of the exterior surface. A receptacle wall of the housing is disposed around the bore wall and is radially spaced from the bore wall to form a channel between the bore wall and the receptacle wall. A restriction indicator measures a restriction in the interior volume and displays an indication of the restriction. The restriction indicator includes a stem that is at least partially insertable into the bore that engages an inner surface of the bore wall. One or more tabs of the restriction indicator are at least partially insertable in the channel and removably couple to the receptacle wall.

Abstract: A self-calibration method of determining remaining useful life of an internal combustion engine's air filter includes establishing a pressure drop versus mass airflow rate relationship for a clean air filter using pressure drop, mass airflow rate, and temperature data captured at low and elevated engine speeds. The method also includes establishing a maximum clean air filter pressure drop at a preset maximum airflow using the clean filter relationship. The method additionally includes establishing a pressure drop versus mass airflow rate relationship for an in-service air filter using pressure drop, mass airflow rate, and temperature data captured at low and elevated engine speeds. The method also includes determining a maximum in-service air filter pressure drop at the preset maximum airflow using the in-service filter relationship. The method further includes comparing the maximum clean and in-service air filter pressure drops to determine the remaining useful life of the in-service air filter.

Abstract: Disclosed is a method for detecting the clogging of an air filter including the following steps when the cross section for the passage of air in an intake tract is greater than a predetermined passage cross section: measuring a pressure in the intake tract at the end of a phase of admitting air into a cylinder; measuring a pressure in the intake tract at the end of an exhaust phase in a cylinder; and determining that the air filter is clogged by comparison between at least one pressure measured during a pressure measurement at the end of the phase of admitting air into a cylinder and, on the other hand, a pressure measured during a pressure measurement at the end of the exhaust phase, the filter being estimated to be clogged when the comparison yields a value higher than a predetermined value.

Abstract: An air purifying prompting system includes an air purifying system and a prompting server wirelessly communicated with the air purifying system. The air purifying system includes an air purifying processor, an air filter communicating with the air purifying processor, a positioning module for positioning the air purifying system, and an air quality sensor for detecting air quality around the air purifying system, wherein the prompting server is arranged to generate an air filter usage time data. The air filter usage time is used to activate generation of air filter prompting signals to the air purifying system.

Abstract: The present disclosure relates to an exhaust scavenging system for an engine system including an engine enclosed in an engine enclosure and an air intake system including an air filter having a filter element for filtering air. The exhaust scavenging system includes an exhaust conduit, a venturi, and a valve system. The exhaust conduit is coupled to the engine and is configured to receive exhaust gas discharged by the engine. The venturi is associated with the exhaust conduit and operates to generate a suction to draw air from the air filter and the engine enclosure. The valve system is configured to selectively fluidly connect the venturi with the engine enclosure or the air filter. The valve system fluidly connects the venturi with the air filter for facilitating purging of the filter element of the air filter.

Abstract: Methods and systems are provided for reliably prognosing a vehicle component, such as a vehicle battery or an intake air filter. A state of degradation of the component is predicted based on a metric that is derived from a sensed vehicle operating parameter, the parameter selected based on the component being diagnosed, as well as based on past driving history and future driving predictions. The predicted state of degradation is then converted into an estimate of time or distance remaining before the component needs to serviced, and displayed to the vehicle operator.

Abstract: Methods and systems are provided for determining a status of an air filter in an intake of an engine in a hybrid vehicle. One example method includes, during an engine-off condition, utilizing a pump in an evaporative leak check module of the hybrid vehicle to produce a pressure in an intake manifold of the engine, and indicating degradation of the air filter based on a comparison of barometric pressure and the pressure produced in the intake manifold. In this way, degradation of the air filter may be determined without engine operation.

Abstract: An apparatus and a method for controlling engine RPM (Revolutions Per Minute) for a construction machine are disclosed, which can compulsorily decrease the engine RPM when an air filter clogging signal is generated. The method for controlling engine RPM for a construction machine including an engine, an air filter, an air filter clogging switch, an engine electronic control unit (E-ECU), and a vehicle electronic control unit (V-ECU), includes determining whether the air filter is clogged in accordance with a signal from the air filter clogging switch, continuously accumulating an engine operating time without initializing the engine operating time even if an engine start is turned off after the air filter clogging signal is generated, determining whether the air filter is repaired or replaced if the accumulated engine operating time exceeds a predetermined time after the air filter clogging signal is generated, applying a control signal from the V-ECU to the E-ECU to compulsorily decrease the engine RPM to predetermined RPM if the air filter is not repaired or replaced in a state where the accumulated engine operating time exceeds the predetermined time, and decreasing the engine RPM to the predetermined RPM in accordance with the control signal that is applied from the E-ECU to an engine driving unit.
