Abstract: Noise attenuation units are disclosed that are connectable in a system as part of a fluid flow path. Such units include a housing defining an internal cavity and having a first port and a second port each connectable to a fluid flow path and in fluid communication with one another through the internal cavity, and a noise attenuating member seated in the internal cavity of the housing within the flow of the fluid communication between the first port and the second port. The noise attenuating member enables the fluid communication between the first port and the second port to flow through the noise attenuating member.

Abstract: Methods and systems for improving vacuum generation for an engine that may be operated at higher altitudes are presented. In one non-limiting example, a transmission that is mechanically coupled to the engine may be shifted from a gear to neutral in response to an actual total number of times a vehicle brake pedal is applied and partially released while the vehicle is stopped and the brake pedal is applied.

Abstract: A manually adjustable aspirator is disclosed for use in a vacuum system for a vehicle having a vacuum source. The aspirator includes a passageway having a diameter that can be adjusted by a vehicle operator for different altitudes. The aspirator includes a body, a passageway having a narrowed aperture defined by opposed cones, and a manually adjustable flow adjuster having an adjustment knob. A brake booster is connected to the aspirator. An air intake is connected with a vacuum source and the aspirator. The cones include first and second cones each having a narrowed end. The narrowed ends are joined at a narrow aperture that defines an inner diameter. The flow rate adjuster regulates the size of the inner diameter. Adjustment of the knob allows operator selection between a high boost in a high altitude location and a low boost in a low altitude location having a higher source vacuum.

Abstract: This blow-by gas recirculation device for an internal combustion engine of a vehicle is provided with a vacuum pump which supplies negative pressure to a brake booster. The blow-by gas recirculation device includes: a fresh-air introduction passage for introducing a fresh air into crankcase from an intake passage upstream of a throttle valve; a PCV device for recirculating, to the intake passage downstream of the throttle valve, blow-by gas in the crankcase; and a suction/recirculation means which uses the vacuum pump to suck the blow-by gas from inside the crankcase, in a region where the blow-by gas ventilation quantity by the PCV device is insufficient, and recirculate the blow-by gas to the intake passage, while the fresh air is being introduced from the fresh-air introduction passage. As a result, the blow-by gas concentration in the crankcase is reduced, engine oil contact opportunities are reduced, and oil deterioration is inhibited.

Abstract: A control device calculates an estimate of negative intake pressure based on the relationship between the rotation speed of a crankshaft and a throttle opening degree (Step S24). Then, the control device sets the estimate PE of the negative intake pressure, which is calculated in Step S24, to a greater value as combustion efficiency of CNG used in engine operation becomes higher (Step S25). When the corrected estimate PE of the negative intake pressure becomes smaller than or equal to a reference value PTh (Step S26: YES), the control device starts a negative pressure recovery procedure (Step S27).

Abstract: Methods and systems are provided for regulating engine operating parameters such as exhaust gas recirculation (EGR) based on road roughness conditions. Based on increased road roughness estimation, EGR flow rate may be opportunistically raised, enabling NVH associated with elevated EGR levels to be masked by NVH associated with rough road conditions. In addition, purging of fuel vapors from a canister or a crankcase to the engine may be increased while transmission shift schedules may be advanced so as to complete the shift during the rough road condition.

Abstract: Check valves are disclosed that have a housing defining an internal cavity having a first port and a second port both in fluid communication therewith, and having a first seat defined by a first elastomeric V-ring seal and a second seat. and a check valve plate within the internal cavity that is translatable, in response to pressure differentials, between a closed position against the first seat and an open position against the second seat within the internal cavity of the housing. The first elastomeric V-ring seal includes a body having an interference fit to an annular channel defined by the housing and a lip extending from the body in a direction that defines a generally V-shaped void, viewed in cross-section, opening in a direction away from and generally perpendicular to the flow through the elastomeric V-ring seal into the internal cavity.

Abstract: Methods and systems are described for diagnosing degradation of a vacuum actuator in an engine system. An example method comprises indicating degradation of the vacuum actuator based on an estimate of flow of air into and out of a vacuum reservoir. The estimate is further based on flow of air generated via each of an aspirator in the intake system, an actuation of the vacuum actuator, and leakage during the actuation of the vacuum actuator.
