Oil mist separator

Номер: US20120159912A1
Автор: Stefan Ruppel
Принадлежит: MAHLE International GmbH

An oil mist separator for a crankcase ventilation system in an internal combustion engine is disclosed. The oil mist separator is an impact type separator that includes a nozzle device having at least one nozzle, an impact wall and a separation material configured therebetween. The impact wall is located opposite to the at least one nozzle and may be coated with the separation material. A distance is configured between the nozzle and the separation material, and is reduced compared to a surrounding region, and wherein the separation material in a region of the opposing nozzle projects towards the same and thereby reduces the distance of a nozzle outlet to the separation material in this region compared to the surrounding region.

FAILURE DETECTION DEVICE FOR BLOW-BY GAS RECIRCULATION APPARATUS OF ENGINE

Номер: US20150040878A1
Автор: Yoshioka Mamoru
Принадлежит:

An engine includes a EGR valve to regulate a EGR flow rate. A blow-by gas recirculation passage allows blow-by gas generated in the engine to flow in a surge tank to return to the engine. A PCV valve operates in response to negative pressure to regulate a blow-by gas flow rate in the recirculation passage. During deceleration fuel cutoff of the engine, an ECU holds a throttle valve at a predetermined slight opening degree and controls the EGR valve to be forcibly opened from a valve-closed state to change intake pressure (negative pressure) in the surge tank and determines whether or not the PCV valve is in sticking failure based on changes in intake amount detected by an air flow meter before and after the negative pressure changes. 1.
