摘要： The arrangement for controlling the flow of laden gases is arranged upstream of an oil separation system and is provided with a check valve, a bypass valve and a stationary segment. The check valve is at least partially movable so as to define a first passage for a forward first flow direction in the event of positive pressure, while the bypass valve is moved rearward by negative pressure so as to clear a second passage for a second, opposite, flow direction. The stationary segment forms a seating surface for the bypass valve. The bypass valve, urged against the seating surface by an elastic biasing member, forms a seat for the check valve. In the event of sufficient negative pressure, the two valves are moved rearward together despite the biasing member and work together to redirect and guide the flow along an escape path corresponding to the second passage.

摘要： A valve for controlling a gas stream between a first side and a second side of the valve is described. A valve opening is passage for the gas stream between the first side and the second side. A valve closure with a valve plate closes the valve opening. A valve mount is arranged toward the second side and on which the valve closure is mounted. The valve closure is pretensioned in the direction of the first side to close the valve toward the second side by the valve plate. The valve plate has an opening element which can be opened toward the first side in the event of an overpressure on the second side.

摘要： An internal combustion engine has a control device, an EGR valve that adjusts an EGR rate, a PCV valve that adjusts an opening degree of a first PCV passage that communicates an inside of a crankcase and a downstream side of a throttle valve. The control device operates the throttle valve in a closing direction in response to a deceleration request. The control device adjusts an opening degree of the PCV valve based on an immediately preceding EGR rate immediately before reception of the deceleration request.

摘要： There is provided an engine capable of reducing oil consumption. The engine includes a cylinder head, a cylinder head cover mounted above the cylinder head, a rocker arm covered by the cylinder head cover, and a breather chamber provided inside the cylinder head cover. As a front-rear direction is defined by a longitudinal direction of the cylinder head cover, the breather chamber has a blow-by gas inlet at one side in the front-rear direction, a blow-by gas outlet at another side in the front-rear direction, and an oil discharging guide chamber at an intermediate part in the front-rear direction. The blow-by gas inlet is opened on a bottom wall of the breather chamber, and a peripheral wall of the oil discharging guide chamber is protruded downwardly from the bottom wall of the breather chamber toward between the rocker arm provided at a side of the blow-by gas outlet and the blow-by gas inlet.

摘要： An internal combustion engine includes a supercharger, an oil tank, a scavenging pump, a first passage, a second passage, and a one-way valve. The supercharger is provided in an intake passage. The oil tank communicates with a crankcase via a collecting passage. The scavenging pump is provided in the collecting passage to transport a fluid in the crankcase to the oil tank. The first passage connects an upper space located above a liquid surface in the oil tank and a downstream portion of the intake passage located on a downstream side with respect to the supercharger. The second passage connects the upper space and an upstream portion of the intake passage located on an upstream side with respect to the supercharger. The one-way valve is provided in the first passage and allows the fluid to flow only from the upper space toward the intake passage.

摘要： Methods and systems are provided for using a crankcase vent tube pressure or flow sensor for diagnosing a location and nature of crankcase system integrity breach. The same sensor can also be used for diagnosing air filter plugging and PCV valve degradation. Use of an existing sensor to diagnose multiple engine components provides cost reduction and sensor compaction benefits.
